The highest payout casinos for Kiwis — best RTP, tested in NZD

What RTP is: a worked NZD example

Return to player is the proportion of total money wagered on a game that's paid back to players over a very large number of plays. The remainder is the house edge. RTP and house edge always add up to 100%.

Here's the worked example in dollars. Imagine a pokie with a published RTP of 96.1%. Over the long run, for every NZ$100 wagered on that game, it returns on average NZ$96.10 to players and keeps NZ$3.90 as the house edge (3.9%). Scale that up: wager NZ$1,000 at 96% RTP and, over the long run, roughly NZ$960 flows back to players while NZ$40 is the house's take.

The crucial words are "on average" and "long run". That NZ$960 is a statistical average measured across millions of spins by thousands of players, not a promise about your session. In a single sitting you might turn NZ$100 into NZ$400, or lose the lot in twenty spins. The RTP only becomes visible over an enormous sample. So a higher RTP doesn't mean you'll win; it means the game is cheaper to play on average, and your bankroll should last longer before the edge grinds it down.

Quick rule of thumb. Moving from a 92% pokie to a 96% one cuts the house's take from NZ$8 to NZ$4 per NZ$100 wagered, over the long term — per turnover, not per session. Every point of RTP you give up is money handed to the house.

NZ law, tax & payments

Is this legal in NZ? New Zealand has no licensed domestic online casinos. Under the Gambling Act 2003 the sites Kiwis use are all offshore (Curaçao, Anjouan, Malta), and the Department of Internal Affairs (DIA) regulates the space as it affects players. It's not illegal for you to play at these offshore sites. A new Online Casino Gambling regime is on the way, with the first DIA licences expected in 2026 and offshore operators needing to be licensed to keep taking Kiwi custom thereafter. We update this page as the regime progresses.

Are winnings taxable? For nearly all NZ residents, no. Inland Revenue treats recreational gambling wins as a non-taxable windfall, not income, so you don't declare them or pay tax on your winnings — no matter how high a game's RTP. The rare exception is a genuine professional gambler whose betting is a business. If in doubt, confirm with IRD or an accountant.

A quick note on payments. Ignore any site still advertising POLi; it was discontinued in 2022 and can never be used. Current options for Kiwi players include Visa and Mastercard, online bank transfer / Account2Account, Neosurf (handy for small sub-NZ$5 deposits), Skrill, Neteller and MuchBetter, Paysafecard, Apple Pay and Google Pay, and cryptocurrencies such as BTC, ETH, USDT and LTC, which also tend to deliver the fastest withdrawals. Payment method affects deposit and withdrawal speed, not the RTP of the games you play.

Responsible gambling in New Zealand

Gambling should be entertainment you can afford, not a way to make money — and a high RTP is not a way to make money either. Over the long run, on every game, the house edge still favours the casino. If play stops feeling like fun, help is free and confidential.
