During our tests, one site emerged as the best paying online casino in New Zealand. But we had other strong contenders in specific areas, like fair bonuses or blackjack games with high Return to Player (RTP) rates. Check out our top recommendations for each category below:
Each top payout casino has unique strengths, but they share one thing in common – every site on our list is licensed by a reputable gambling authority, ensuring legal and safe gambling.
Casino Payout Rate and Winning Chances: Why They Matter in Online Casinos
Want to boost your chances of winning at online casinos? Understanding payout rates is the way. There are RTP guides that dive deeper, but the most important thing to remember is that it’s all theoretical. There is no guarantee of success even at the casino with the best payouts.
Important to remember: Volatility also matters—high-volatility games pay less frequently but with bigger wins. Knowing this will help shape your strategy.
We found Betway’s casino payout rate auditor listed in the footer of the website.
Can You Trust the Stated Casino Payout Percentages?
You can trust the stated average RTP rates at the top payout online casinos we’ve reviewed because they are officially licensed. Legit sites undergo regular fairness audits by independent organisations like eCOGRA and GLI.
Pay attention: Exceptionally high casino payout percentages (over 99%) are often a red flag, indicating potential manipulation. To avoid this, stick to reputable, licensed casinos.
Which are the Highest Payout Casino Games?
The casino’s overall payout is an average of all its games, so the type of game you choose matters! Here are some of the best games for higher payouts— just remember that the exact percentage can vary due to differences in mechanics and rules.
Top 10 Best Payout Casino Games
Blackjack – 98.03% – 99.93%
Video Poker – 90.00% – 99.00%
Baccarat – 98.76% – 99.50%

Best Payout Casino Slot Games
RTP in slots can vary widely because each game is designed with unique features and mechanics. For example, jackpot slots typically have lower payout rates because a portion of each bet contributes to the jackpot prize.
Many popular online slots in New Zealand offer high RTP rates. Some of the highest ones you will encounter are Book of 99 by Relax Gaming and Jackpot 6000 by NetEnt. Here are some more games that boast RTPs above 97.50%:

Should you need further details regarding the payout rates at top NZ online casinos or how these theoretical figures are calculated, our team of experts is ready to help.
What is the payout rate of a casino and how to calculate it?
The casino payout rate is the average payout percentage of all games listed on the casino. It is a theoretical value that is changing with every gaming update on the site.
What is the best payout for an online slot in New Zealand?
The list of highest online slot RTP in New Zealand changes frequently as new games come out. Currently, some of the highest payouts you can find are on slots like Book of 99, Jackpot 6000, and 1429 Uncharted Seas.
What's the difference between payout rate and house edge?
These are the two sides of the same coin. While the RTP rate presents the percentage of all wagers that go back to the players, the house edge presents the opposite - the percentage the casino keeps as revenue.
