Betting promotions in New Zealand — what the offers really cost
Available in US
Betting promotions in New Zealand in 2026 are unusual for one reason: there is only one operator allowed to take your bet. Since section 74AAA of the Racing Industry Act 2020 came into force on 28 June 2025, TAB NZ and its online sister brand Betcha have held the only lawful licence for racing and sports betting offered to people in New Zealand. The Department of Internal Affairs told every unlicensed provider to withdraw with immediate effect. That single-rule market is the frame every offer, bonus bet and free-bet headline has to be read inside — and the frame changes what those words are worth.
This page walks through how a promotion is actually priced, what the rule costs the person claiming it, and what the offshore “welcome offers” New Zealanders keep meeting online can and cannot do for them.
*Current as of October 30, 2026 against TAB NZ’s published terms and the Department of Internal Affairs register.*
How a Promotion Is Valued: The Cost Behind the Headline
A betting promotion is a number on a banner. It is worth what it pays back after the wagering rule, the minimum odds and the deadline are taken off. Most of the headline is marketing; the value lives in the next four paragraphs.
What a “Free Bet” Actually Returns
A free bet (or a TAB NZ “Bonus Bet”) is a token you stake on a market. If the bet wins, the operator pays the profit at the stated odds. The stake of the free bet is not given back alongside the profit. That rule is what makes “free” misleading and what fixes the offer’s true value.
A stake of $10 placed at decimal odds 1.90 wins $9.00 of profit if the leg lands. The $10 free-bet stake stays with the operator. Net return to the bettor: $9.00 on a $10 token. The offered “free bet” has cost the operator $10 only on a loss; on a win it has cost them $9.00.
TAB NZ calls its promotional stake “Bonus Cash” and splits it across multiple bets; the same stake-not-returned principle applies unless its terms say otherwise. Read them.
The Wagering Rule and the Bonus-Bet Cycle
A wagering rule (or “rollover”) asks the bettor to turn the bonus over a set number of times at a stated minimum odds before any winnings can be withdrawn. The rule is the part the marketing copy leaves out. TAB NZ’s own bonus terms sit behind the same package.
The arithmetic is straightforward. Suppose a $30 Bonus Cash comes with a 1× turnover rule at minimum odds of 1.50. The bettor must place bets totalling $30 of bonus stake at odds of 1.50 or higher. A single qualifying bet of $30 at 1.60 clears the bonus in one move; a $10 bet at 1.50 takes three moves. None of this returns the original $30 of Bonus Cash on a win — only the profit counts as withdrawable, subject to the operator’s own fine print.
The Expected Cost of a Bonus-Bet Promotion
A promotion’s real cost is what the wagering rule costs the bettor on average, given the margin baked into the market they bet on.
Take the same $30 Bonus Cash on a 1× turnover at minimum odds 1.50, wagered entirely on a single two-way market priced at 1.90 / 1.90. The payout share of that two-way market at equal prices is 1 ÷ (1/1.90 + 1/1.90) = 1 ÷ (1.0526) = 0.9500, or 95.00%. The bookmaker’s margin is 1 minus that, or 5.00%.
The expected cost of clearing the offer, if the bettor wagers the bonus through the qualifying market, is turnover × margin = $30 × 5.00% = $1.50. That is the average slice of every dollar wagered that the bookmaker keeps. The bettor’s expected position after clearing: $30 of profit paid only on winning legs, minus an expected $1.50 of margin absorbed across the turnover. Net expected: positive on a low-margin market with a low turnover; negative once the turnover climbs.
The lesson: the higher the wagering multiple, the more the margin eats. A 5× turnover on the same $30 at the same market costs an expected $7.50.
The Free-Bet Value Formula
For a free bet whose stake is not paid back, value = free-bet amount × (odds − 1) ÷ odds × payout share of that market.
Plug the inputs. Free-bet amount $30, decimal odds 1.90, two-way market at 1.90 / 1.90 with payout share 95.00%.
Step 1. (1.90 − 1) ÷ 1.90 = 0.90 ÷ 1.90 = 0.4737.
Step 2. 0.4737 × $30 = $14.21 of expected gross value before the market margin.
Step 3. $14.21 × 0.9500 = $13.50 expected value.
The free bet is worth about $13.50 on average, against a headline of $30. That is the headline-to-value gap the rule creates, and it scales the same way on any market: a free bet at shorter odds returns less; at longer odds returns more, capped by the bookmaker’s market margin and any payout ceiling in the offer’s terms.
A band, not a figure: depending on the market the bettor chooses and the minimum odds in the offer, the same $30 free bet is worth between roughly $12 and $16 on a 95.00%-payout-share market. Higher-margin markets (a 7% margin instead of 5%) cut that band by around $1.50.
What to Check Before Claiming
Five things decide whether a promotion is worth claiming:
- The wagering multiple. One turn of the bonus is common at TAB NZ; five or ten turns on offshore brands is routine.
- The minimum odds. Bets below the minimum do not count; check whether singles, multis or both qualify.
- The deadline. Some offers expire the bonus in 7 days, some in 30; unused bonus expires with it.
- The market exclusion. Many offers exclude tote (pool) bets, enhanced odds or cashed-out wagers from the qualifying turnover.
- The payout ceiling. Free-bet winnings are sometimes capped; a win above the cap is paid only to the cap.
Read the operator’s own terms page. No headline number on the marketing banner answers any of these.
The Single-Operator Landscape
New Zealand’s betting market is a monopoly by statute. That is unusual globally and reshapes every comparison a reader can make.
TAB NZ: One Operator, Two Brands
TAB NZ operates two online brands: TAB and Betcha. They are not rivals; they are the same operator under different skins, both run by Entain under a 25-year partnership 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, plus a one-off $100 million payment Entain pledged to the racing sector at signing.
The TAB NZ app offers Same Race Multis, Same Game Multis, one-tap Popular Multis and a Place Extra option for runners to finish up to 10th in selected races. Betcha offers a Multi Builder with trending multis and a live-leg tracker, a daily Toolbox of odds boosts and insurance tools, a Bet Social feed and a Playbook with tips and match analysis.
Because there is no second licensed bookmaker to comparison-shop against, the “best bonus in New Zealand” is whichever TAB NZ promotion is live in the app. The competition is between today’s offer and next week’s.
Offshore Brands New Zealanders Keep Meeting
New Zealand-based readers will see online welcome offers from offshore brands: 100% deposit bonuses, free-bet welcome packages, boosted odds on the Premier League. None of these brands may lawfully take a sports or racing bet from a person in New Zealand. Section 74AAA covers the offer, the acceptance of the bet and the payment of winnings: the breach happens when the operator accepts a New Zealand-customer wager, and the operator is liable.
Offshore brands carry no New Zealand complaints route and no New Zealand harm-minimisation framework. The Department of Internal Affairs warns that overseas operators may sit in jurisdictions with minimal consumer safeguards, may not return unspent credits and may not pay out large wins. The point-of-consumption charge that once applied to offshore racing and sports bets ceased on 30 June 2026; a tax being payable did not make the offer lawful in the first place and its removal does not unmake it now.
The offshore brands listed in the comparison below are referenced because New Zealand players see their advertising; they are not licensed in New Zealand and the offers on their sites are not available to a person betting from a New Zealand address.
The Statute Behind the Monopoly
Section 74AAA of the Racing Industry Act 2020 is the legal reason there is one online bookmaker in New Zealand. The Racing Industry Amendment Act 2025 inserted it; the change came into force on 28 June 2025.
What the Section Says
The section prohibits any person other than TAB NZ from offering racing betting, sports betting or other racing or sports betting to a person in New Zealand. The rule applies regardless of where the offeror is resident or incorporated: an Anjouan licence, a Curaçao licence, a Tobique licence — none of them gives a right to take bets from people in New Zealand.
How It Is Enforced
The Department of Internal Affairs monitors compliance with the betting prohibition under section 92A of the same Act. After the section came into force, the Department told providers serving New Zealand to withdraw with immediate effect. There is no licensing route for another bookmaker and no licence register for betting: the register exists only because there is one lawful operator.
The penalty for breaching section 74AAA is not stated in the section, and no prosecution of an offshore bookmaker was found. The Department of Internal Affairs’ power sits in its standing authority over the Gambling Act 2003 framework and its direction to withdraw.
What the Player Faces
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 betting operator in breach of section 74AAA. No published penalty for the player was found. The law targets the operator; the Department of Internal Affairs warns players of the risks. New Zealand does not block bookmaker websites at the network level, so a player can reach an offshore brand; the legal liability for offering the bet sits with the operator, not the bettor.
A greyhound-racing note: greyhound racing is closing in stages from 1 August 2026. From that date, offshore operators may not take bets on greyhound races either.
What the Casino Law Does Not Do
The Online Casino Gambling Act 2026 licences online casino gambling only. TAB New Zealand winning the right to apply for a casino licence does not extend the betting monopoly. The 2026 Act does not create a betting licence, does not open the door to a second TAB NZ competitor and does not authorise an offshore bookmaker. A casino-style rule such as a $100 / 200% inducement cap is a casino rule, not a betting rule, and does not govern a sports-betting bonus.
Responsible Gambling Tools and Help
Player-protection rules in New Zealand differ by product. Betting and casino are separate permits with separate rules; the protections for one do not always extend to the other.
The Age Rule for Betting
The age for TAB NZ betting is 18. Betting under 18 is an offence under section 89 of the Racing Industry Act 2020. Land-based casino gambling in New Zealand is gated at 20. The 18-vs-20 split matters: an offer promoted as “21+ on the operator’s site” is an operator-level term, not a New Zealand rule.
The Tools in the TAB NZ App
The TAB NZ app lists three harm-minimisation tools: deposit limits, time-outs and self-exclusion. A self-exclusion applies across TAB NZ’s brands (TAB and Betcha), so an exclusion on TAB covers Betcha and vice versa. There is no single national online-betting exclusion register; the register the casino law will require is for online casinos only.
Betcha carries a 17+ App Store age rating, lists Safer Betting tools in-app and displays the Gambling Helpline number prominently.
The Help Lines
The free Gambling Helpline 0800 654 655 and the text line 8006 are available 24/7. Safer Gambling Aotearoa runs alongside. These are the same lines TAB and Betcha list in their apps.
The Levy That Funds Treatment
TAB NZ pays a Problem Gambling Levy of 0.74% of its betting revenue, in force from 1 July 2025 to 30 June 2028. The levy funds problem-gambling treatment services. Offshore operators that supply New Zealand residents pay online gambling duty (12% of profits since 1 July 2024, 16% from 1 January 2027); a duty being payable does not make an offer lawful.
The Advertising Code
The Advertising Standards Authority’s Gambling Advertising Code applies to betting advertisements in New Zealand. Ads must not target children (under 14) or young people (14 to under 18), judged by context, appeal and expected audience; an audience of 25% or more of the relevant age group counts as significant where accurate audience data exists. Ads must not encourage harm and must be truthful with terms available. No New Zealand equivalent of a “whistle-to-whistle” broadcast ban was found.
The Top-10 in the New Zealand Frame
A reader comparing betting offers in New Zealand in 2026 is comparing one operator’s promotions with itself and asking how the offer compares with what an offshore site offers. The list below covers the two lawful brands first, then offshore brands New Zealanders encounter, marked for what they are.
TAB
TAB is one of two online brands of TAB NZ, the only provider lawfully offering racing and sports betting to people in New Zealand since 28 June 2025. New TAB NZ customers can receive Bonus Cash that can be split across multiple bets; the app lists 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. Same Race Multis, Same Game Multis and one-tap Popular Multis are part of the in-app experience; Place Extra lets punters back runners to finish up to 10th in selected races.
The cost to claim. No published New Zealand rule caps a bonus size or fixes a wagering multiple; the only binding terms are TAB NZ’s. Read the turnover, the minimum odds and the qualifying-market list before staking Bonus Cash.
The verdict. The lawful option, with New Zealand harm-minimisation tools and a regulator behind it. The trade-off is the absence of competition: there is no second bookmaker to push a better headline.
Betcha
Betcha is the second online brand of TAB NZ, marketed as a younger, app-first experience. The Multi Builder builds multi bets and tracks live legs; the daily Toolbox offers odds boosts and insurance tools for bets that do not land; the Bet Social section hosts chat, tipsters and shared bets or pools; the Playbook publishes tips and match analysis. Safer Betting tools sit in-app alongside the Gambling Helpline number.
The cost to claim. The same TAB NZ bonus framework applies because Betcha and TAB are one operator; offers on Betcha are governed by the same terms that govern TAB. The only practical difference is product surface: more in-app community features, more multi-builder tooling, no tote products that TAB carries.
The verdict. The same operator as TAB in a different wrapper. Choose on interface and feature preference, not on offer price — the offers are the same set run by the same back office.
Rooster.bet
Rooster.bet is operated by Novatrix SRL, a company incorporated in Costa Rica with registration number 3-102-893958, under e-gaming licence No. 0000002 issued by the Tobique Gaming Commission. The brand is not licensed in New Zealand; only TAB NZ may offer racing and sports betting here (see Statute section). The Tobique licence provides no authorisation for New Zealand customers, and no local complaints or harm-minimisation framework covers this brand.
The verdict. Offshore. The licence on the terms page is not a New Zealand licence and does not make the brand lawful here. The site’s marketing offers are restricted to residents of other jurisdictions, not New Zealand.
Spinbara
Spinbara advertises a first deposit bonus of 100% up to EUR 100 and a sport crypto welcome bonus of 100% up to 200 USDT on its English site, alongside a casino welcome bonus of 100% up to EUR 500 plus 200 free spins. The brand is not licensed in New Zealand and the offers sit behind a verification gate that includes a New Zealand address field; a New Zealand customer does not pass that gate lawfully.
The verdict. Casino-anchored brand with a sportsbook attached. The headline bonus numbers look generous against TAB NZ’s offers — but the offer is not available in New Zealand, and the casino rules do not extend to sports betting under New Zealand law.
Sportaza
Sportaza offers cash out before an event or market is finalised, Bet Builder (if one selection is void the whole betslip is void), multiples, Asian lines and interval markets in 1, 5, 10 or 15 minute ranges. The brand names an Anjouan licence (ALSI-202606064-FI2), which does not authorise the acceptance of bets from New Zealand customers as outlined in the Statute section.
The verdict. Product-rich sportsbook with deep market coverage. This depth remains inaccessible from a New Zealand address, as section 74AAA applies to the operator’s conduct, and Sportaza’s offers are strictly prohibited for New Zealand-resident players.
22Bet
22Bet offers over 30 market types per event, including 1X2, Double Chance, totals, both teams to score, correct score and HT-FT, plus tennis game, set and handicap markets. The brand names a Curaçao licence (8048/JAZ), holder TechSolutions Group N.V., which confers no such right for the New Zealand market (see Statute section).
The verdict. Wide market menu, generic Curaçao-licensed brand. Same offshore status as the others on this list; the depth of markets is a function of the product, not a New Zealand compliance fact.
Thunderpick
Thunderpick advertises a 100% deposit bonus up to EUR 600 on its English site and recommends crypto for fast deposits, with other payment methods also available. The brand is esports-first, covering CS2, League of Legends, Dota 2 and Valorant, and the sportsbook offers a cash-out feature and markets from the Champions League to the NFL. The brand names a Curaçao licence (OGL/2024/677/0722), holder Paloma Media B.V.
The verdict. Esports-anchored. New Zealand law has no settled definition for esports betting under the Racing Industry Act, creating an uncertain zone on top of the operator’s already-unlawful status — the default interpretation remains that an offshore esports wager from a New Zealand address violates section 74AAA.
Glorion
Glorion offers pre-match and live betting, virtual sports, horse racing and esports, with markets grouped into popular, niche, indoor and outdoor sports plus entertainment events such as award shows and elections. The brand names no licence that applies in New Zealand.
The verdict. Entertainment markets (politics, award shows) sit in a second grey zone: the Racing Industry Act’s definition of “sports betting” is not established for those categories, and the operator’s status as offshore stands regardless.
Golden Panda
Golden Panda offers a Sports section with a sportsbook, esports and virtual sports, plus casino, live casino, crash games, rewards, cashback, a VIP Club, Golden Goals and Prediction Markets. The brand names no licence that applies in New Zealand.
The verdict. Casino-heavy brand with a sportsbook tacked on. The product surface is wide but the licence status is identical to the rest of the offshore set: the brand’s offers are effectively off-limits to New Zealand-resident customers.
Winz.io
Winz.io runs a sports betting bonus promotion with separate Sportsbook T&C, Sports Rules and Bonus Terms and Conditions pages. The brand names Anjouan and Tobique licences, holder Novatrix SRL, neither of which authorises the acceptance of bets from New Zealand residents under section 74AAA.
The verdict. Same operator group as Rooster.bet under a different brand. The licence tokens do not translate into a New Zealand right to bet, and the bonus is generally not available to a person in New Zealand.
Comparison Across the New Zealand Set
The table below lines up the brands covered on this page on the matters a reader comparing a promotion might check. Every cell carries a specific from TAB NZ’s own terms, the operator’s own terms or from the regulator’s statement on the brand’s New Zealand status; gaps are left where the inputs do not cover them, not filled with speculation.
| Brand | New Zealand status | What the operator’s own terms state on the offer |
|---|---|---|
| TAB | TAB NZ brand — only provider lawfully offering racing and sports betting to people in New Zealand | Bonus Cash that can be split across multiple bets; Mega Multi bonus of up to $50 in Bonus Cash when a four-plus-leg multi falls short by a set number of legs |
| Betcha | TAB NZ brand — only provider lawfully offering racing and sports betting to people in New Zealand | Daily Toolbox of odds boosts and insurance tools; Multi Builder with trending multis; Bet Social feed |
| Rooster.bet | Not licensed in New Zealand — only TAB NZ may offer racing and sports betting to people in New Zealand | Tobique Gaming Commission licence (No. 0000002); operator under Costa Rica registration 3-102-893958; offers not available in New Zealand |
| Spinbara | Not licensed in New Zealand — only TAB NZ may offer racing and sports betting to people in New Zealand | First deposit bonus 100% up to EUR 100; sport crypto welcome bonus 100% up to 200 USDT; offers not available in New Zealand |
| Sportaza | Not licensed in New Zealand — only TAB NZ may offer racing and sports betting to people in New Zealand | Cash out before settlement; Asian lines; 1/5/10/15-minute interval markets; offers not available in New Zealand |
| 22Bet | Not licensed in New Zealand — only TAB NZ may offer racing and sports betting to people in New Zealand | Over 30 market types per event including 1X2, Double Chance, totals, BTTS, correct score and HT-FT; offers not available in New Zealand |
| Thunderpick | Not licensed in New Zealand — only TAB NZ may offer racing and sports betting to people in New Zealand | 100% deposit bonus up to EUR 600; esports-first; offers not available in New Zealand |
| Glorion | Not licensed in New Zealand — only TAB NZ may offer racing and sports betting to people in New Zealand | Pre-match and live betting, virtual sports, horse racing and esports plus entertainment markets; offers not available in New Zealand |
| Golden Panda | Not licensed in New Zealand — only TAB NZ may offer racing and sports betting to people in New Zealand | Sportsbook plus casino, live casino, crash games, cashback, VIP Club; offers not available in New Zealand |
| Winz.io | Not licensed in New Zealand — only TAB NZ may offer racing and sports betting to people in New Zealand | Sports betting bonus promotion under separate Sportsbook T&C; offers not available in New Zealand |
The pattern in the table is the page’s point. Only the first two rows carry New Zealand status as “TAB NZ brand”; the other eight carry the same status line because section 74AAA does not differentiate by brand or licence. The offer column varies because each offshore brand markets differently; what does not vary is the unavailability of those offers to a person in New Zealand.
The Cost of Betting Offshore from a New Zealand Address
Section 19(4) of the Gambling Act 2003 says an individual may not be convicted for placing a bet with an offshore operator in breach of section 74AAA. No published penalty for a player was found. The Department of Internal Affairs targets the operator, not the bettor. That is the legal posture.
The practical cost is sharper. An offshore brand carries no New Zealand complaints route: a dispute over a voided bet, a delayed payout, an unreturned balance has no New Zealand body to escalate to. 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 self-exclusion on TAB NZ applies across TAB and Betcha but does not reach an offshore site. A deposit limit set on TAB NZ does not cap deposits elsewhere.
The Player Safety section below covers the help lines; the same lines apply whether the bet was placed with TAB NZ or with an offshore brand.
Reading a Promotion: A Checklist
Use this when an offer crosses your screen, regardless of the brand.
- The wagering multiple. One turnover of the bonus at TAB NZ is the baseline; an offshore brand asking for five or ten is asking more of your time.
- The minimum odds. Bets below the minimum do not count toward turnover.
- The deadline. Unused bonus expires when the deadline passes.
- The market exclusion. Some offers exclude tote bets, enhanced odds or cashed-out wagers.
- The payout ceiling. Free-bet winnings are sometimes capped above the headline odds.
- The withdrawal rule. Some offers pay bonus as free bets whose stake is not returned.
- The New Zealand status. If the brand is not TAB NZ, is the offer available to a person in New Zealand? The legal answer is no; the practical answer is the same.
Player Safety
Set Your Limits Before You Bet
TAB NZ’s deposit limits, time-outs and self-exclusion are the three levers every account has. Set the deposit cap on day one of account opening; raise it only after a cooling-off period, never on the same day. A self-exclusion covers both TAB and Betcha.
Know the Help Lines
The free Gambling Helpline (0800 654 655) and the text line 8006 are 24/7. Safer Gambling Aotearoa provides online resources. Both TAB and Betcha display the helpline number prominently in their apps.
Watch the Marketing
The Advertising Standards Authority’s Gambling Advertising Code applies to New Zealand betting advertising. Ads must not target under-18s and must be truthful with terms available. If an ad crosses a line, the ASA is the body to report it to.
Know the Tax Posture
Recreational gambling winnings in New Zealand are generally not taxable to the player, and prize money from TAB horse, dog and trotting races is not taxable. A person who bets as a business is a different case; for general information, consult Inland Revenue or an accountant. Operator-side taxes (the Problem Gambling Levy, online gambling duty on offshore operators supplying New Zealand residents) are not a player concern.
Betting Under 18
Betting under 18 in New Zealand is an offence under section 89 of the Racing Industry Act 2020. Land-based casino gambling is gated at 20. The 21+ age note that recurs on offshore sites is an operator term, not a New Zealand rule.
What the 2026 Promotion Calendar Looks Like
TAB NZ runs “bonus bets” promotions throughout the year. No New Zealand rule on bonus size or wagering terms was found, so every figure below is what TAB NZ publishes, not what a regulator sets.
Racing Codes and Their Cycles
TAB NZ takes bets on thoroughbred, harness (trots) and greyhound racing. Greyhound racing closes in stages from 1 August 2026; from that date the multis and promos tied to greyhound cards are not available. The Melbourne Cup in late October / early November is the headline racing event in the Australian spring and runs through TAB NZ as part of its international racing coverage; the promo Calendar offers full-year coverage of Cup Day and the surrounding Spring Carnival.
Sport-by-Sport Coverage
TAB NZ offers sports betting on rugby union (All Blacks, Super Rugby Pacific), rugby league (NRL, Warriors), cricket (Black Caps), football and the major European leagues. Betcha and TAB both carry the same event menu under TAB NZ’s terms.
Major Events Worth Watching For Promo
The Spring Racing Carnival (Melbourne Cup, Cox Plate, Caulfield Cup), the NRL Finals, Super Rugby Pacific playoffs, the Black Caps’ home internationals, the FIFA World Cup cycle, the NFL playoffs and Super Bowl, the NBA Finals and the UEFA Champions League final are the events around which TAB NZ typically builds its larger promotional offers.
When a Promotion Looks Too Good
Three checks before claiming.
The Stake-Not-Returned Rule
If the offer is a free bet, the stake is not paid back with the winnings. A $30 free bet at 1.90 wins $9.00 of profit; it does not win $39.00. Read the offer’s payout rule.
The Minimum Odds Clause
If the offer asks for minimum odds of 1.50 and the bettor places a bet at 1.30, the bet does not count. Three bets at 1.30 do not equal one at 1.50. Read the offer’s minimum-odds rule.
The Deadline and the Ceiling
If the offer expires in 7 days and the bettor has not turned the bonus over, the bonus is forfeit. If the offer caps free-bet winnings at $200 and the bet wins $350, the bettor is paid $200. Read the offer’s deadline and ceiling.
The Arithmetic of a TAB NZ Bonus Bet
Take a TAB NZ Bonus Cash offer of $30, a 1× turnover at minimum odds 1.50, and a qualifying two-way market at decimal odds 1.90 / 1.90.
The market’s payout share at 1.90 / 1.90 is 1 ÷ (1/1.90 + 1/1.90) = 1 ÷ 1.0526 = 0.9500, or 95.00%. The bookmaker’s margin is 5.00%.
Turnover needed: $30 × 1 = $30. Number of qualifying bets: one bet of $30 at 1.60, or three bets of $10 at 1.50 — both clear the bonus.
Expected cost of clearing the bonus at the qualifying market: $30 × 5.00% = $1.50.
Expected value of the bonus as a free bet: $30 × (1.90 − 1) ÷ 1.90 × 0.9500 = $30 × 0.4737 × 0.9500 = $13.50.
The headline is $30; the expected value is about $13.50 on this market. The gap is the stake-not-returned rule, the bookmaker’s margin and the wagering rule working together. Adjust the odds and the margin changes; the formula scales the same way.
FAQ
Are there New Zealand rules on the size or terms of a betting bonus?
No. No New Zealand rule on bonus size or wagering terms was found, so every binding figure comes only from TAB NZ’s own terms. The online casino law’s inducement cap applies to licensed online casinos and does not govern sports-betting offers.
Why is the stake of a free or bonus bet not paid back with the winnings?
The operator pays the profit at the stated odds; the stake of the free bet stays with the operator. That is why “free” is misleading and why a $30 free bet at 1.90 wins $9.00 of profit, not $39.00. TAB NZ’s Bonus Cash follows the same stake-not-returned principle unless its terms say otherwise.
Which bookmaker may lawfully take sports and racing bets in New Zealand?
TAB NZ and its two online brands, TAB and Betcha, are the only providers lawfully offering racing and sports betting to people in New Zealand since 28 June 2025 under section 74AAA of the Racing Industry Act 2020. No licensing route for another bookmaker exists and no licence register for betting exists because there is only one lawful operator.
How is the return on a bet worked out from the stake and the odds?
For a single bet at decimal odds, return equals stake multiplied by odds, and net profit equals stake multiplied by (odds minus one). For a multi bet, the odds of the legs multiply into one price. A $10 stake at 1.90 returns $19.00, of which $9.00 is profit.
Which tools for controlling play do TAB and Betcha offer, and who can be called for help?
TAB NZ’s app lists deposit limits, time-outs and self-exclusion; an exclusion applies across both TAB and Betcha. The free Gambling Helpline is 0800 654 655, with a text line at 8006, available 24/7. Safer Gambling Aotearoa runs alongside.
What does a player lose by betting with a bookmaker that has no New Zealand licence?
The player loses a New Zealand complaints route, the New Zealand harm-minimisation framework, the cross-brand self-exclusion and the deposit-limit framework that TAB NZ provides. The Department of Internal Affairs warns that overseas operators may sit in jurisdictions with minimal consumer safeguards, may not return unspent credits and may not pay out large wins.
