Betting offers in New Zealand: what every promotion really costs a punter
Updated 30 October 2026 · Verified against the Racing Industry Act 2020 and the Department of Internal Affairs register.

A “free bet” sits on almost every betting site in the world. The word is identical everywhere; what it does once it reaches a New Zealand punter is not. Since the Racing Industry Amendment Act 2025 came into force on 28 June 2025, only one operator may lawfully take racing and sports bets from a person in New Zealand: TAB NZ, the state-backed totalisator and bookmaker, running two online brands, the long-established TAB and its newer sister site Betcha. Every other welcome offer a New Zealand reader sees online arrives from an operator that, by definition, is breaking the law to serve that reader. The size of the bonus, the percentage match, the cap on winnings, the “100%” headline, the wagering multiplier of “just” 5x, all of it lands in a market the law treats as a closed one.
That makes the cost question the one that matters most. A reader weighing a $50 free bet, a 100% deposit match, a risk-free first wager, a boosted odds headline or a multi bonus wants to know the figure behind the figure: how much of the bonus clears, how much returns on a win, and how much is simply burned through by the bookmaker’s margin inside the qualifying bets. That is the lens this page uses throughout. It opens with the incentives themselves, ranks the ten brands a New Zealand reader actually encounters, sets the legal frame the offers live inside, names the safer-gambling tools that ride alongside, and closes with a worked example of what a free bet is worth on an average bet at 1.90.

What a “betting offer” actually is in New Zealand
A betting offer is the marketing wrapper a bookmaker puts around three underlying mechanisms: a sign-up bonus paid in real money, a free bet whose stake is not returned with the win, and a boosted odds enhancement applied to one specific market. Each shape carries a different cost shape, and the cost lives in the wagering terms, not in the headline number.

New Zealand’s legal monopoly matters here, because it removes the choice the offers pretend to provide. Only TAB NZ may lawfully offer racing and sports betting to people in New Zealand under section 74AAA of the Racing Industry Act 2020. There is no second licensed bookmaker. There is no whitelist of approved offshore sites. The Department of Internal Affairs told providers serving New Zealand to withdraw with immediate effect on 28 June 2025. That means the comparison a reader does online — TAB versus Bet365 versus Betfair versus the next brand a search result returns — is not a comparison of equals under New Zealand law. It is a comparison of one legal option and several illegal ones.
The offers are still real. TAB NZ runs Bonus Cash promotions, including a Mega Multi bonus of up to $50 in Bonus Cash when a multi of four or more legs falls short by a set number of legs. Offshore brands market 100% deposit matches, reload bonuses, cashback on losses, boosted odds on big games and refunded first bets to New Zealand traffic regardless of that prohibition. The headline numbers can look generous. The cost of clearing them, once the margin of every qualifying bet is taken into account, is the part the marketing copy does not put on the page.
The three shapes of a betting incentive
A cash bonus is the simplest. The bookmaker matches a deposit by a percentage, pays the bonus into the account, and lets the punter bet with it. The cost is the wagering requirement: a multiple that says “turn this over N times before any winnings are withdrawable”. A 100% match up to $100 with a 5x wagering requirement means a punter must place $500 of qualifying bets before the bonus, and any winnings from those bets, becomes cash.
A free bet is more confusingly named. The bookmaker credits an amount to bet with. If the bet wins, the punter keeps the profit — stake multiplied by (odds minus one) — but the stake is not paid back. A $50 free bet at 2.00 returns $50 profit, not $100. Free bets are the format most often called “risk-free” by marketers, and that word is doing a lot of work: a losing free bet is not refunded in cash; it is usually refunded as another free bet, which has the same stake-not-returned rule attached.
A boosted odds enhancement is the third shape. The bookmaker raises the price on one market above its listed value, paying the difference in cash if the bet wins. The cost is concentrated in the qualifying market: the boosted price is fine, but it usually comes with a maximum stake and a single-use constraint. A punter who uses a boosted odds token twice, or on a market it does not apply to, gets the standard price and not the headline.

What an offer costs once the market is added
Each of those three shapes leaves a cost on top of the obvious number. The wagering multiplier applies to qualifying bets at a minimum price; bets below that price usually do not count. The bookmaker’s margin is built into every qualifying price the punter places; a market margin of 5% means $5 of every $100 wagered is kept by the house on average. If the wagering requirement is $500 at a 5% margin, the expected cost of clearing is $25 — on top of any maximum-win cap the offer carries.
The reading order this page recommends: read the offer’s wagering multiple, then its minimum qualifying odds, then the expiry window, then the maximum withdrawal cap. The headline bonus size is the last figure worth knowing, because it is the one the marketing emphasises and the one the cost clauses override.
Reading the TAB NZ and BETTA offers at face value
TAB NZ is the only legal bookmaker for racing and sports in New Zealand since 28 June 2025, and the offers on its two brands are read in their own terms. They do not follow the offshore pattern of a deposit match plus a free bet plus a reload. They sit closer to a tote-style customer-loyalty structure, with the wagering built into the product and the bonus attached to multi and same-game-multi formats.
The flagship incentive on TAB NZ’s app is Bonus Cash. New customers receive a Bonus Cash credit that can be divided across multiple bets rather than spent on a single wager. The format suits a punter who already plans to place several multi bets, because the bonus stretches through several bets instead of one.
The flagship multi-feature offer is the Mega Multi bonus. A multi of four or more legs that falls short by a set number of legs triggers a return of up to $50 in Bonus Cash. The mechanism is a partial-refund insurance on the legs that did land, paid as bonus credit rather than as cash. The cost of that insurance is twofold: only one multi per day qualifies, the bonus is capped at a defined maximum, and the bonus cash carries its own turnover before it withdraws.
Betcha, the newer TAB NZ brand, structures its incentives differently. The daily Toolbox in the app carries odds boosts and “insurance” tools on bets that do not land, the Bet Social section lets punters copy trending bets and follow tipsters, and the Playbook holds tips and match analysis. None of those is a sign-up match in the offshore sense. They are engagement tools layered on top of the same betting product, and the cost of accepting one is the cost of accepting any market: the bookmaker’s margin in the price.
What stands out, comparing the two brands against offshore welcome packages, is that neither TAB NZ brand advertises a wagering multiplier. There is no “5x rollover” stamp on the Bonus Cash terms the way an offshore site might phrase it. The New Zealand statute does not set a rule on bonus size or wagering terms for TAB NZ; the figures come only from TAB NZ’s own terms. That absence of a published rollover figure is the single biggest structural difference between the legal New Zealand market and the offshore sites that target it.
What the offshore sign-up offers look like next to TAB NZ
Offshore operators serve New Zealand traffic with the standard offshore welcome package: a 100% deposit match, a free bet stake on the first wager, reload bonuses on later deposits, and boosted odds on a marquee event. The numbers sound large and the wagering requirements are smaller than the offshore norm used to be. From the punter’s point of view, the headline is what is being sold. From the cost point of view, the headline is what is being used.
A representative example across the offshore sites a New Zealand reader meets: a 100% first deposit bonus up to EUR 100 (Spinbara, Boomerang Bet, BetNinja in this set), with wagering terms published on the operator’s own page. The match is paid as bonus credit, the credit carries a rollover before it becomes cash, and bets below the qualifying odds do not count toward the rollover. The cost of clearing the bonus is the rollover times the market margin. A punter who clears EUR 100 of bonus with a 5x rollover at a 5% market margin burns an expected EUR 25 of the bonus to the house edge.
A second shape is a refunded first bet or a matched free bet. The bookmaker credits a free bet equal to the punter’s first wager, up to a cap, and pays out the winnings if the bet lands. The stake is not returned on a win, and a losing first bet is usually refunded as another free bet — the “refund” wording in the headline does not mean a cash refund. The cost is twofold: the stake-not-returned rule on the original bet, and the same rule on the refund if the first bet loses. Both bets are paid at the book’s margin.
A third shape is a boosted odds enhancement on one marquee event. The bookmaker raises the price above the listed value, pays the difference if the bet lands, and limits the qualifying stake to a small number. The cost is concentrated on that single bet and is limited by the stake cap.
Why the headline figure overstates what is on offer
The 100% match is the most common offshore headline. Read as raw cash, it doubles the punter’s bankroll on day one. Read as bonus credit, it doubles the bankroll on day one only if the punter clears the wagering requirement at a net positive rate, which the market margin makes structurally unlikely at scale. A punter who runs out of qualifying bets before clearing the bonus loses the bonus. A punter who clears the bonus pays the margin on every qualifying bet. The expected net, on the bonus alone, is the bonus size minus (rollover × market margin) minus the chance of failing the rollover entirely.
The refunded first bet is the second most common headline. Read as cash, it insures the first wager up to the cap. Read as a refund-in-bonus-credit, it shifts the first bet from a real-money wager to a bonus-credit wager, and the bonus credit carries the stake-not-returned rule that the real-money first bet did not. The expected net is the win chance of the first bet multiplied by the bonus size, minus the cost of the underlying margin the punter paid on the first bet.
The boosted odds is the third most common headline. Read as a price lift, it raises the return on a specific event. Read as a stake cap, it limits how much the price lift can be worth. The expected net is the cap times the price lift times the win probability of the bet, minus the cost of the underlying margin.
In each case, the headline figure is the marketing word, and the cost clauses are the actual figure. The two are not the same number.
Where the cost actually lands
A wagering requirement is the most expensive figure in any betting offer, and the easiest to miss. It is expressed as a multiple of the bonus or the deposit, and it is applied to bets at a minimum qualifying price. A punter who bets below the qualifying price does not progress toward the rollover. A punter who bets at the qualifying price pays the margin on every qualified bet. A punter who runs out of the rollover window forfeits any bonus progress not yet converted to cash.
A minimum qualifying odds clause is the second most expensive figure. It is the floor below which bets do not count. A 1.50 minimum is cheap to clear because most markets qualify. A 2.00 minimum is more expensive because favourite prices are usually below 2.00 and the punter has to back outsiders to clear. The minimum price interacts with the rollover: a high minimum price on a high rollover is the most expensive combination on the page, because it forces the punter to bet on the markets where the bookmaker’s margin is the highest.
A maximum withdrawal cap is the third most expensive figure. It caps how much of the bonus winnings the punter can convert to cash. A 10x cap on a EUR 100 bonus caps the cash payout at EUR 1,000 — generous on a free bet but stingy on a big multi. The cost of the cap is the difference between the actual win and the capped payout, which the punter does not see until after the win.
A bonus expiry is the fourth most expensive figure. It is the deadline by which the rollover must be cleared. A 30-day expiry on a 5x rollover is workable. A 7-day expiry on a 5x rollover is tight, and forces the punter to bet in volume rather than in selectivity. The cost of the expiry is the margin the punter pays on unnecessary bets.
What “minimum odds” really means at the betting slip
The minimum qualifying odds clause is the part of an offer where the cost hides in plain sight. A 1.50 minimum looks permissive — most markets qualify — but the markets that do qualify at 1.50 carry the bookmaker’s full margin. A punter placing a EUR 5 qualifying bet at 1.50 pays the EUR 5 bet at the underlying market margin, which is the bookmaker’s cut of every euro staked at that price. The cost is not in the rollover number; it is in every bet the punter places to satisfy the rollover.
What a wagering requirement looks like in practice
A 5x rollover on a EUR 100 bonus requires EUR 500 of qualifying bets at minimum odds to clear the bonus. A punter who places 100 bets of EUR 5 each at 1.80 across a range of markets places EUR 500 of bets, clears the rollover, and converts the bonus to cash. The cost is the margin on 100 bets at 1.80 — roughly EUR 25 on a typical 5% margin. The expected net to the punter is EUR 75 in cleared bonus minus EUR 25 in margin paid: EUR 50, on a bonus headline of EUR 100.
Top 10 betting offers available to New Zealand readers
The comparison below ranks the brands a New Zealand reader actually encounters, with the legal status named plainly at the top of each row. TAB and Betcha are the two lawful online brands of TAB NZ, the state-backed bookmaker and totalisator. The remaining eight are not licensed in New Zealand; the Department of Internal Affairs has told operators serving New Zealand to withdraw, and any offshore brand taking bets from a person in New Zealand is in breach of section 74AAA of the Racing Industry Act 2020.
The numbers in the third column are the offers each operator’s own terms state. None has been verified against TAB NZ’s regulator beyond TAB and Betcha, because the regulator does not oversee the rest. Where the offer was not seen on the New Zealand-facing version of the operator’s site, the column reports the version research actually recorded.
| Brand | New Zealand status | Operator’s own terms on the offer |
|---|---|---|
| TAB | TAB NZ brand (lawful) | Bonus Cash on signup, divisible across multiple bets; Mega Multi bonus of up to $50 in Bonus Cash when a multi of 4+ legs falls short by a set number of legs; no published rollover multiplier in the app’s listed terms |

Sources and their caveats: TAB and Betcha’s incentive listings are drawn from the New Zealand App Store listings for each app, which mirror the published terms. The offshore rows are drawn from each operator’s own promotional pages and terms pages, which in several cases (Telbet, Spinbara, BetNinja) state offers in currencies or versions not targeted at New Zealand readers. SpinBetter, LunuBet, Ivibet, Tonybet, Megapari, Boomerang Bet, Thunderpick and BetWinner were considered in research and are not featured, either because no New Zealand-facing version of their offer was located or because their licence and product fit the same not-licensed-in-New-Zealand bracket.
Why TAB and Betcha lead the comparison under New Zealand law
TAB and Betcha take every stake at the bookmaker’s margin, and the rest of this page treats them as one operator. The reason is structural, not competitive: under the Racing Industry Amendment Act 2025, TAB NZ is the only lawful provider of racing and sports betting to people in New Zealand, and the two online brands run off the same totalisator pool, the same betting rules, and the same fixed-odds engine. The TAB NZ partner Entain runs the betting business under a 25-year agreement signed in 2023 that gives Entain a 50/50 share of gross profits, with at least $150 million a year going to TAB NZ for the first five years and a one-off $100 million payment to the racing sector.
That partnership matters to a New Zealand punter because it determines what “Bonus Cash” actually funds. TAB NZ’s offer is paid out of the TAB business, and the TAB business funds the racing code: thoroughbred, harness and greyhound racing, plus the codes’ own integrity infrastructure. A punter using TAB NZ’s Bonus Cash on a multi bet contributes to that funding chain in a way an offshore bookmaker’s deposit match does not.
Why the offshore brands appear in the comparison anyway
New Zealand readers meet offshore brands whether the law likes it or not. Search results surface them, social media advertises them, and several accept New Zealand customers without checking a New Zealand address. The comparison above includes them so the reader can see what each one’s own terms actually state, and so the legal status of each row is named in the same place as the offer it carries. It does not include them so a reader signs up. The illegal-for-the-operator line under each offshore row is the operative fact, and the wagering terms in the third column are what the operator publishes.
How the rows are ranked
The ranking is not by bonus size. It is by which bookmaker a New Zealand reader can actually use under New Zealand law, then by what the offer is worth once wagering and the market margin are taken into account, then by the breadth of the offer across the legal brands TAB and Betcha. TAB and Betcha rank first because they are the only lawful options and because their offers do not carry an offshore-style rollover. The offshore brands follow in alphabetical order, because none of them is legal in New Zealand and ranking them on offer size or wagering terms suggests a comparison the law does not support.
What the law actually says about betting offers in New Zealand
The legal frame around a New Zealand betting offer is short and very firm. Three statutes do almost all the work: the Gambling Act 2003, the Racing Industry Act 2020, and the Racing Industry Amendment Act 2025. A fourth, the Online Casino Gambling Act 2026, governs online casino gambling only and does not license sports betting.
The Racing Industry Act 2020 and the 2025 amendment
The Racing Industry Act 2020 established TAB NZ as the body that may offer racing betting and sports betting to people in New Zealand. The Racing Industry Amendment Act 2025 inserted section 74AAA: no person other than TAB NZ may offer racing betting, sports betting or other racing or sports betting to a person in New Zealand, regardless of where that person is resident or incorporated. The amendment took effect on 28 June 2025, and the Department of Internal Affairs told providers serving New Zealand to withdraw with immediate effect.
The change did not extend TAB NZ’s monopoly into casino gambling. TAB NZ’s success in applying for a casino licence under the Online Casino Gambling Act 2026 is a casino matter, not a betting matter. The casino law caps online casino inducements at $100 per customer per day and 200% of the deposit; that cap is on the casino side and does not govern betting offers. A punter who sees a 100% deposit match advertised under a TAB NZ brand’s casino product is reading the casino rule, not the betting rule.
What may be bet on under the Act
The Act covers racing and sports betting. Racing means thoroughbred, harness and greyhound races held in New Zealand or abroad, and TAB NZ runs fixed-odds and tote (pool) bets on them; published betting rules cover Win, Place, Each Way, Quinella, Exacta, Trifecta, First Four, Double, Treble, Daily Double, Running Double, Quaddie, Big6, Multis and Same Game Multis. Sports betting means betting on the outcome of a sporting event, and TAB NZ’s sports product carries football codes, rugby codes, cricket, basketball, tennis and other sports through its app.
Greyhound racing is closing in stages from 1 August 2026. From that date, offshore operators may not take bets on greyhound races either. Bets on politics and novelty markets are not established under the Act. Esports is not categorised one way or another. Virtual sport is treated as casino gambling under the Online Casino Gambling Act 2026 and falls outside this page.
What the offshore operators cannot lawfully do
Since 28 June 2025, an offshore bookmaker taking sports or racing bets from a person in New Zealand is breaking New Zealand law under section 74AAA. The Department of Internal Affairs has stated the prohibition, but the Act does not state a penalty for the offshore operator in section 74AAA and no prosecution of an offshore bookmaker was found in the public record. New Zealand does not block bookmaker sites at the network level, and the law puts liability on the offshore operator rather than on the punter.
The punter is not in the same position. Section 19(4) of the Gambling Act 2003, inserted in 2025, says an individual may not be convicted for placing a bet with an offshore operator in breach of section 74AAA. No source states a penalty for a player. The right framing is the one the Department of Internal Affairs itself uses: the law targets the operator, the regulator warns players of the risks, and no published penalty for a player was found. Betting offshore is not illegal for the punter; it is unregulated for the punter.
What this means for the offer a punter actually sees
A 100% deposit match offered by an offshore brand to a New Zealand reader is, on the operator’s side, an inducement to place bets in breach of section 74AAA. On the punter’s side, it is an offer from an operator that does not come under New Zealand consumer-protection rules, that is not subject to the New Zealand Advertising Standards Authority’s Gambling Advertising Code, and that has no obligation to pay out a winning bet. The Department of Internal Affairs warns that overseas operators may be in jurisdictions with minimal consumer safeguards, may not return unspent credits, and may not pay out large wins.
A punter using an offshore brand’s free bet in New Zealand has three protections missing: no regulator to complain to in New Zealand, no harm-minimisation framework that reaches the operator, and no guarantee the operator will return winnings if the punter’s account is restricted. The offer looks the same as a TAB NZ Bonus Cash incentive. The envelope around the offer is not the same.
Bonuses and free bets: how each shape pays out in practice
A “betting offer” in New Zealand in 2026 takes four practical shapes: the Bonus Cash credit on TAB NZ, the Multi Bonus insurance on TAB NZ, the Boosted Odds enhancement on Betcha’s daily Toolbox, and the offshore deposit match plus free bet on the brands not licensed in New Zealand. Each shape pays out differently, and the cost differs accordingly.
TAB NZ Bonus Cash
Bonus Cash is the only sign-up incentive TAB NZ publishes on its app. New customers receive a Bonus Cash credit that can be split across multiple bets, rather than a single lump. The credit carries its own terms, published in the app, and those terms describe how the credit converts to cash and over what timeframe. The credit is paid in New Zealand dollars and is funded from the TAB business that TAB NZ and Entain run jointly.
Cost shape: the cost is the bookmaker’s margin on every bet the Bonus Cash funds. There is no separate rollover multiplier on top of the underlying market margin. A punter placing three multi bets of $20 each with a $50 Bonus Cash credit pays the bookmaker’s margin on each multi; the credit does not add a second margin on top.
Payout shape: the bonus credit pays out the profit on winning bets at the listed odds, with the stake treated as bonus credit (not real money) for the purpose of the cash conversion. A $50 bonus credit on a winning $20 multi at 3.00 returns $40 profit, paid back into the punter’s account, with the stake credited back as bonus credit rather than as cash until the conversion terms are met.
TAB NZ Mega Multi bonus
The Mega Multi bonus is the flagship multi-insurance product on TAB NZ’s app. A multi of four or more legs that falls short by a set number of legs triggers a return of up to $50 in Bonus Cash, paid into the punter’s account on the next betting day.
Cost shape: the cost is the opportunity cost of placing a multi rather than a series of singles. The Mega Multi bonus does not increase the multi’s odds, and a multi’s margin is the product of the legs’ margins. A four-leg multi where each leg is at 1.80 carries a higher margin than four single bets at 1.80, and the Mega Multi bonus does not refund that higher margin. The bonus is a partial refund of the stake, not a margin discount.
Payout shape: the bonus is paid as Bonus Cash, which carries its own conversion terms. The bonus does not pay out as cash, and the cap at $50 is the maximum Bonus Cash the punter receives on a single qualifying multi.
Betcha’s daily Toolbox
The Betcha Toolbox is a daily set of odds boosts and insurance tools on selected events. The boosts raise the listed price on a market for the duration of the offer, and the insurance tools refund part of the stake on a losing bet as a bonus credit.
Cost shape: the cost is the stake cap on each boost. A boosted odds token limited to a $10 maximum stake limits the upside of the boost to $10 times the price difference. The insurance tool carries a maximum refund and a minimum qualifying stake.
Payout shape: the boost pays out the listed profit at the boosted price if the bet wins. The insurance pays out the refund as Bonus Cash if the bet loses, with the refund subject to the same conversion terms as the TAB NZ Bonus Cash.
The offshore deposit match plus free bet
The offshore welcome package combines a deposit match paid as bonus credit with a free bet stake on the first wager. The package carries a rollover on the matched bonus, a minimum odds clause on the rollover, and a stake-not-returned rule on the free bet. The free bet is usually refunded as another free bet if the first wager loses, and the “risk-free” wording in the marketing does not describe a cash refund.
Cost shape: the cost is the wagering multiplier applied to the matched bonus at the minimum odds, paid at the bookmaker’s margin on each qualifying bet, plus the stake-not-returned rule on the free bet stake. A punter clearing a EUR 100 deposit match at a 5x rollover with a 1.80 minimum odds and a EUR 50 free bet pays the margin on EUR 500 of qualifying bets plus the stake-not-returned cost on the EUR 50 free bet. The expected total cost is roughly EUR 30 to EUR 40 on a typical 5% margin market.
Payout shape: the deposit match pays out the profit on winning bets at the listed odds, with the stake treated as bonus credit. The free bet pays out the profit on the winning bet at the listed odds, with the stake not returned. A EUR 50 free bet at 2.00 returns EUR 50 profit, not EUR 100.
How the four shapes compare on cost
A punter choosing between TAB NZ’s Bonus Cash, TAB NZ’s Mega Multi bonus, Betcha’s Toolbox and an offshore deposit match plus free bet is choosing between four cost shapes, not four headline numbers. The Bonus Cash carries the underlying market margin only. The Mega Multi bonus carries the multi’s compounded margin plus the cost of taking a multi over singles. The Toolbox carries the stake cap on each boost plus the insurance refund’s conversion terms. The offshore package carries the rollover, the minimum odds, the stake-not-returned rule on the free bet and the underlying margin on every qualifying bet.
The headline numbers do not sort that way. The TAB NZ Bonus Cash credit may be smaller in headline than the offshore 100% match, and the Mega Multi bonus may be smaller than the offshore risk-free first bet. The cost-to-clear number is the opposite way around, because the TAB NZ offers do not layer a rollover on top of the market margin.
What the Bonus Cash is worth on an average bet
The worked example this page owes the reader is what a free bet is worth on an average bet, applied to TAB NZ’s Bonus Cash credit on a representative two-way market at decimal odds 1.90 on each side. The arithmetic belongs to the free-bet-value formula, and the inputs come from TAB NZ’s own terms and from the chosen market.
The formula and its inputs
For a free bet whose stake is not paid back with the winnings, the value is the free-bet amount multiplied by (odds minus one), divided by the odds, multiplied by the payout share of the market. Value = free-bet amount × (odds − 1) ÷ odds × payout share.
The payout share of a two-way market at 1.90 / 1.90 is 1 ÷ (1 ÷ 1.90 + 1 ÷ 1.90) = 1 ÷ (0.5263 + 0.5263) = 1 ÷ 1.0526 = 0.9500, or 95.00%. The bookmaker’s margin on the same market is 1 − 0.9500 = 0.0500, or 5.00%. The market is a 5% margin market, which is in the band of leading bookmakers’ top-flight football and a totalisator’s near-1.90 / 1.90 split.
The result on a $50 free bet
A $50 Bonus Cash credit placed on a two-way market at 1.90, with the stake not returned, returns on average: $50 × (1.90 − 1) ÷ 1.90 × 0.9500 = $50 × 0.4737 × 0.9500 = $22.50 of expected value on the credit. The $50 stake is not paid back on a win; only the profit counts toward the bonus conversion. The $22.50 is the average return across a large number of bets at this price, not the return on any single bet.
The result is a band, not a single figure, because the value varies with the market’s margin. A punter placing the same $50 credit on a market at 1.80 / 1.80 (a margin of about 5.56%, payout share of 94.44%) returns $50 × (1.80 − 1) ÷ 1.80 × 0.9444 = $21.00. A punter placing the same credit on a market at 2.00 / 2.00 (a margin of 5.00%, payout share of 95.00%) returns $50 × (2.00 − 1) ÷ 2.00 × 0.9500 = $23.75. The band across these representative markets is $21.00 to $23.75.
What the band means
The $22.50 figure is the average return across all qualifying bets at 1.90 / 1.90. It is not the return on any single bet: a winning $50 free bet at 1.90 returns $50 profit, and a losing one returns nothing. The expected value is the average over a large number of bets at this price, not a guaranteed outcome for any single punter. The stake-not-returned rule is what makes the expected value less than the headline $50.
This is the cost the marketing copy does not put on the page. A $50 free bet is, on average at 1.90, a $22.50 credit, not a $50 credit. A punter treating it as a $50 credit overstates the offer by 2.2 times. The narrower the margin and the higher the odds, the closer the credit gets to half the headline; the wider the margin and the lower the odds, the smaller the credit is as a share of the headline.
What this changes about choosing between offers
The free-bet-value figure is the cost-to-clear number an offer can be compared against. An offshore 100% match up to EUR 100, cleared at a 5x rollover at the book’s 5% margin, costs the punter roughly EUR 25 in margin before any cap on winnings. The expected net of the bonus is the EUR 100 bonus minus the EUR 25 cost, or about EUR 75. The expected net of a $50 free bet on a 1.90 / 1.90 market is $22.50 in bonus conversion. The two figures are not the same shape: the deposit match is a larger headline with a rollover cost; the free bet is a smaller headline with a stake-not-returned cost.
A punter choosing between them weights the cost of clearing. The deposit match has the higher headline but the higher cost-to-clear. The free bet has the lower headline but the lower cost-to-clear. The ratio of headline to expected net is the comparison, not the headline alone.
The safer-gambling tools and where to get help
The safer-gambling tools on TAB NZ and Betcha are real and they are the same on both brands, because both apps are run by TAB NZ and the exclusion rules apply across the group. The Department of Internal Affairs monitors compliance with the prohibition on offering betting outside TAB NZ, but the safer-gambling regime inside TAB NZ is TAB NZ’s own, supplemented by free helplines.
What TAB NZ and Betcha offer in their apps
TAB NZ’s app provides deposit limits, time-outs and self-exclusion. A punter can set a daily, weekly or monthly deposit cap; once set, the cap cannot be raised without a cooling-off period. A time-out is a short break, from 24 hours to six weeks, in which the punter cannot place bets. Self-exclusion is a longer exclusion, from six months to five years, in which the punter’s account is closed and any pending withdrawals are processed. The exclusion applies across TAB NZ’s brands, so a punter excluded from TAB is also excluded from Betcha.
Betcha’s app carries the same exclusion rules. A punter excluded from Betcha is excluded from TAB, and vice versa. The 17+ App Store age rating on the Betcha app is the iOS-rating-side enforcement of the 18+ age rule for TAB NZ betting; betting under 18 is an offence under section 89 of the Racing Industry Act 2020.
The free helpline
The free Gambling Helpline 0800 654 655 is listed in both TAB NZ’s and Betcha’s apps, alongside the text line 8006. The helpline is staffed by Safer Gambling Aotearoa, the national counselling service for gambling harm. The helpline is free, confidential and available 24/7.
What TAB NZ pays for the harm-minimisation framework
TAB NZ is required by statute to keep the risks of problem and underage gambling minimised, and pays a Problem Gambling Levy of 0.74% of gross profits, in force from 1 July 2025 to 30 June 2028. The levy funds the Ministry of Health’s gambling-harm services and the Gambling Helpline. A punter using TAB NZ’s app is contributing to the harm-minimisation framework through the levy; a punter using an offshore app is not, because the offshore operator does not pay the levy.
What offshore operators offer — and what they do not
Offshore operators not licensed in New Zealand typically offer their own deposit limits, time-outs and self-exclusion, because their home regulator (Curaçao, Anjouan, the Union of the Comoros) requires them. The rules vary by operator and by regulator. No New Zealand consumer-protection framework reaches them, no New Zealand complaints route applies to them, and no New Zealand harm-minimisation levy is paid by them.
The Department of Internal Affairs’s warning that overseas operators may be in jurisdictions with minimal consumer safeguards applies most acutely to the safer-gambling side of the offer. A punter who self-excludes from TAB NZ is excluded across both brands and can enforce the exclusion through the New Zealand complaints route. A punter who self-excludes from an offshore brand depends on the offshore operator’s own enforcement and on the home regulator’s complaints process.
What the cost comes to when the offers are compared
The cost of an offer is the figure the headline does not show. For TAB NZ’s Bonus Cash, the cost is the bookmaker’s margin on every qualifying bet, with no rollover layered on top. For TAB NZ’s Mega Multi bonus, the cost is the multi’s compounded margin plus the cost of taking a multi over singles. For Betcha’s Toolbox, the cost is the stake cap on each boost and the conversion terms on the insurance refund. For the offshore deposit match plus free bet, the cost is the rollover, the minimum odds, the stake-not-returned rule on the free bet and the underlying margin on every qualifying bet.
The four cost shapes sort the four offer types in a way the headlines do not. TAB NZ’s Bonus Cash is the cheapest offer by margin cost and the smallest by headline. The offshore deposit match plus free bet is the largest by headline and the most expensive by margin-plus-rollover cost. A punter optimising on cost-to-clear picks TAB NZ’s Bonus Cash. A punter optimising on headline figure picks the offshore package. The two are not the same choice.
The legal frame sorts them again. TAB NZ’s Bonus Cash is paid in a regulated market under New Zealand law, with consumer protections that reach the operator. The offshore package is paid in a market where the operator is in breach of section 74AAA, where no New Zealand regulator oversees the offer, and where the punter has no New Zealand complaints route. The cost-to-clear number is only one part of the comparison. The legal envelope around the offer is the other.
What the choice comes to for a New Zealand punter
The choice for a New Zealand punter is not between ten offers; it is between the regulated option and the unregulated one. TAB NZ and Betcha are the two lawful online brands and the only two offers a punter can take under New Zealand consumer-protection rules. The offshore brands are not licensed in New Zealand, and their offers are not regulated by the Department of Internal Affairs or the Advertising Standards Authority’s Gambling Advertising Code.
The wagering terms and the headline numbers on the offshore side are not the deciding factor. The deciding factor is the legal envelope, and the legal envelope is closed.
Frequently asked questions
Are there any betting sites in New Zealand that give a free bet?
TAB NZ’s app lists Bonus Cash for new customers, which can be split across multiple bets, and a Mega Multi bonus of up to $50 in Bonus Cash when a multi of four or more legs falls short by a set number of legs. Betcha’s app lists a daily Toolbox of odds boosts and insurance tools on bets that do not land. Both apps are run by TAB NZ under the Racing Industry Act 2020, and there is no rollover multiplier on the Bonus Cash credit in the published terms.
Do offshore welcome offers work for New Zealand punters?
Offshore brands accept New Zealand traffic and advertise 100% deposit matches, free bets and boosted odds, but since 28 June 2025 they are in breach of section 74AAA of the Racing Industry Act 2020 for offering racing or sports betting to a person in New Zealand. The Department of Internal Affairs has told providers serving New Zealand to withdraw. Offshore wagering terms are not enforced by a New Zealand regulator, no New Zealand complaints route reaches them, and the punter’s recovery if a winning bet is not paid out depends on the operator’s home regulator.
Why is the stake of a free or bonus bet not returned on a win?
A free bet is paid as a credit that the punter uses to place a wager; on a winning bet, only the profit is paid out, not the stake, because the bookmaker never took the stake from the punter in the first place. The same rule applies to TAB NZ’s Bonus Cash credit, which is treated as bonus credit until the conversion terms are met. The rule is the standard free-bet mechanic, and the marketing word “risk-free” does not change it.
How is the return on a winning bet worked out from the stake and the odds?
In decimal odds, the total return on a winning bet is stake multiplied by the odds, and the net profit is stake multiplied by (odds minus one). A $20 bet at 3.00 returns $60 in total and $40 in profit. The bookmaker’s margin sits inside the price, so the odds on each side of a two-way market at 1.90 / 1.90 imply a margin of 5% and a payout share of 95%, before any promotion.
Which tools for controlling play do TAB and Betcha offer?
Both apps list deposit limits, time-outs and self-exclusion, and the exclusion rules apply across the two brands. The free Gambling Helpline 0800 654 655 and the text line 8006 are listed in the apps and are staffed by Safer Gambling Aotearoa 24/7. TAB NZ pays a Problem Gambling Levy of 0.74% of gross profits, which funds the helpline and the Ministry of Health’s gambling-harm services.
