Best Online Casinos That Pay Out – What to Look For
While the RTP of games is definitely important when selecting an online casino real money, you should consider more than just payout percentage when choosing the best online casinos. Here at Bookies.com, we have a list of criteria we check off to help us make the best possible choices. The following are the main things we look out for.
Welcome Offer
Welcome offers are one of the most important things for many players when choosing the best high-paying online casino. As their name suggests, these bonuses are designed to welcome players into a new casino and give them a taste of what they have to offer. There are many different types of welcome bonuses available, with online casino free spins and matched deposit bonuses offering bonus cash being the ones you are most likely to encounter.
Loyalty Rewards and VIP Programs
When choosing the best payout casino site in NZ, it is important to look beyond the welcome bonus and see if there are perks available for existing customers. Like welcome bonuses, promotions for existing customers can come in all shapes and sizes, with free spins, deposit bonuses, and cashback offers being the most common at $5 casino deposit sites.
It is also important to see if an online casino offers any loyalty or VIP programs. These are designed to reward the most loyal customers with a selection of different perks and bonuses.
Customer Service
Customer service is a really important aspect of the online casino experience. When choosing a high-payout online casino in New Zealand, ensure the site offers a variety of customer service options, including live chat, email, and phone. Ideally, you also want a service that can be accessed around the clock.
Range of Casino Games
Of course, one of the most important aspects when choosing any online casino is the range of games it offers. The best high-paying online casinos work alongside the industry’s best developers to ensure players are getting the latest and best online gaming content on the market. It is also important that a site offers a variety of games, including online pokies, live casino online games, instant-win titles, and more.
Mobile Casino App
Mobile play is an important part of the modern online casino experience. Mobile casino apps add an extra layer to this, providing players with even more convenience. While not all high payout casino sites offer mobile apps, we will also factor in how good the mobile version of their website is.
Licenced Operator
The safety and security of our readers is of the utmost importance to Bookies.com. As such, all of the high payout online casino sites we recommend in this guide and across our site are fully licensed and regulated by the appropriate regulators, such as the Malta Gaming Authority.
Payment Methods

From Visa casino and POLi casino payments to PayPal casino and online casino Skrill deposits and withdrawals, it's important that your casino of choice supports your preferred options.

Highest Paying Casino Games New Zealand
Now we’ve explored what makes a great high-paying online casino, let’s take a look at some of the most common games you will find at one and what you can expect to win when playing them.
Before you play any casino games, we recommend checking out the game’s pay table to find out crucial pieces of information This includes the RTP, volatility, and maximum win. All of these will give you an excellent idea of the game’s winning potential.
Pokies
Pokies are, by far, the most popular type of online casino game you will find at the highest-payout online casinos in New Zealand. For most online slot games, the RTP sits at around 95-96%, making it lower than some of the other games we will explore in this guide. However, slot games do tend to have much bigger winning potential, with some progressive jackpots being potentially worth millions of dollars. You can check the RTP of a slot game by looking at its pay table at any time and they are often accessible for those with smaller bankrolls at $1 deposit casino sites.
Roulette
Many different versions of roulette online can be played. As such, the RTP will vary depending on which version of the game you are playing. For example, European Roulette has a higher RTP than American Roulette. Standard European Roulette games have an RTP of 97.3%, giving the user a house edge of around 2.7%. American roulette has an RTP of 94%. As you can see, the RTP can be vastly different depending on the version played, so be sure to check the RTP before you play.
Blackjack
Blackjack is another extremely popular card game that has a healthy RTP. When playing blackjack online, the house edge sits as low as 0.61%. However, players can reduce this slightly by using blackjack strategy, which is a system based on how to react depending on the dealer’s cards. This can reduce the house edge to as low as 0.4%, making this one of the friendliest games for players you can find at a high-paying online casino in New Zealand.
Baccarat
Baccarat online is similar to blackjack in that players can use strategies to reduce the house a little. In a standard baccarat game, the RTP is around 98.76% when you back the player, whereas if you back the dealer, it is around 98.94%, further reducing the house edge. Like roulette, many different versions of baccarat are available, so be sure to check the pay table before you hit the spin button.

RTP vs House Edge
You might find them quite confusing if you are new to phrases such as house edge and return to player (RTP). However, they are much easier to understand than you would think. RTP refers to the percentage of their stake a player is likely to see returned over time, whereas the house edge indicates the amount of money a casino is likely to win from you over a period of time.
You can work out one by knowing the other. For example, if the RTP in an online pokie is 97.8%, the house edge for the game is 2.2%.
Players should remember that RTPs and the house edge are not guaranteed indicators of how a game will play out. Players are never guaranteed to land a win when playing any casino game. Instead, these numbers are based on tests over time and can give you a rough idea of a game’s winning potential.
