    Explained: What is a top paying online casino? The top paying online casinos return the most winnings to players. This is also called casino win rate or RTP (return to player). Win rates show you, on average, how much you can expect to win back over time. A 97% win rate means a $100 bet may return $97. Higher percentages give you better odds, but they are based on tens of thousands of bets and may not reflect in individual results.

    A closer look at the best payout casino

    Thousands of online casinos compete for your business, but they are worth considering if they have one of the best payout rates. Let’s look at our top recommendation and what sets it apart from the competition.

    Pros

    ✅ Best win rate (98.85%) in NZ, the average is around 95%

    ✅ 2,000 games from a massive 80+ providers

    Cons

    ❌ No cryptocurrencies accepted

    Wildz is the cream of the crop when it comes to win rate, boasting a huge 98.85% according to our May data.

    This is thanks to a vast library of high RTP games, including Absolute Blackjack (99.51%), Book of 99 (99%) and 1429 Uncharted Seas (98.5%).

    💡 Editor’s insight: "Thunderkick's 1429 Uncharted Seas is one of the best high RTP pokies you can find. It has a nautical theme which is fairly unique, and an outstanding 98.5% RTP."

    How we rate online casinos

    Any online casino must pass our 25-step review process to make our list of recommendations. This process considers all areas of the casino experience. Below, we’ll discuss in more detail the key points we consider when researching online casinos with top payout rates.  

    • Payout rate

      Payout rate, also known as win rate or return to player, tells you how much an online casino pays back to its customers in winnings on average. The number is shown as a percentage and is based on the average return on a $100 bet. For example, a win rate of 96% means that a casino pays back $96 in winnings for every $100 bet.  

      We only recommend casinos that have a payout rate of 96% or higher because they give you the best chance of winning. However, the best paying online casino available to Kiwis is Wildz Casino, which has a giant 98.94% win rate. 

    • Range of casino games & software

      Top online casinos should have thousands of games available, including pokies with high RTP, and variations of other high RTP games like blackjack and video poker.  

      We also expect to see providers who are industry leaders and well-known for creating titles with high RTPs, such as NetEnt, Microgaming and Playtech. Casinos that tick all these boxes rank highly for our team, like Let’s Lucky, which has 14,000 from 50 software providers.  

    • Casino bonuses & promotions

      All of the casinos we recommend offer welcome bonuses and other promotions for existing players like cash bonuses, free spins and loyalty schemes.  

      To reach the top of our list, casinos have to offer large bonus amounts with favourable terms and conditions, so you have a realistic chance of benefiting from them. For example, Jackpot City Casino offers a cash bonus of NZ$1,800 and 300 free spins on the Mega Millionaire Wheel.   

      The bonus cash's wagering requirements are 35x, which is slightly better than average (40x) for the NZ market. To make things easy, you have seven days to claim the offer.  

    • Overall casino rating

      Playing at a top paying online casino in NZ is nice, but your casino experience goes beyond just that. You can only truly enjoy your time playing if the experience is excellent from start to finish, including elements that have nothing to do with money.    

      Before recommending a casino, we consider several other factors, including customer support, mobile compatibility, and ease of use of the site, which are all important. Let’s Lucky nails all of the above and even has an “Excellent” Trustpilot rating.

    Expert tips – make the most of your casino experience

    Following one of our recommendations and joining a top casino is just the first step. You also need to consider payments, games and strategies. Here are our expert tips to make the most of your time at a casino:  

    1. 1

      Pick the right deposit method for you

      Consider what is most important to you when making deposits and withdrawals and find the best method for that. If you want convenience, use a payment method you already have set up. If you want speed, use an e-wallet; if you want anonymity, use a prepaid card or crypto.  
    2. 2

      Take advantage of promotions 

      Accepting bonuses like free spins and deposit matches can boost your bank roll. Check out our list of sites and pick the one with the bonus that appeals to you most, and always check your email inbox for news on other promotions. Be sure to always check the Ts&Cs before you accept anything though.  
    3. 3

      Manage your bankroll wisely

      A ‘bankroll’ is the amount of money you set aside to use for a set amount of gambling. For example, you could do this per session or by a week or month. Whatever you decide you are willing to gamble, stick to it and never chase losses.   
    4. 4

      Focus on games you enjoy

      Online gambling is all about having fun, so make sure you favour games that you enjoy playing and that you understand. Don’t chase the biggest prizes or bet on games you don’t understand. Stick to what you love, and you’ll have a great time.
