Anyone who has engaged in a bit of online gambling or even visited a gambling website has seen a ‘Welcome Bonus’ message pop-up. It is usually after you’ve spent a few minutes on the website or when you click the ‘back’ button to exit the website.
Unknown to many people the ‘Welcome Bonus,’ also sometimes referred to as a deposit bonus, is used to keep visitors on the website long enough so that hopefully, they can start playing.
However, not all websites label it as a “Welcome Bonus.” Then it is also worth mentioning that some websites are scams and often use inflated welcome bonuses to lure people into entering their payment information. Unfortunately, you’ll never win on a scam casino website, which is why not all welcome bonuses are good!
The best way NZ players and other punters can avoid these scams is to read the terms and conditions of any casino bonus before making transactions. Here are some guidelines to keep in mind when comparing welcome bonuses.
Make sure you understand the wagering requirements and be careful not to fall for offers that sound too good to be true. In case you are wondering, yes, there are offers that are too good to be true.
Finally, we have a list of the most trusted online casinos in NZ that offer some of the most generous welcome bonuses in the industry.
If you’re new to online casinos in NZ, you might be wondering how to claim a welcome bonus. First, you’ll need to sign up and create an account with the casino. After that, you can make one or more deposits—each one may earn you part of the bonus.
Once you meet the required conditions, the bonus will be unlocked. Every casino is different, so always read the bonus terms and conditions carefully before claiming anything.
As stated earlier, all casinos have their own sets of terms that govern when you qualify for a welcome bonus. While some casino welcome bonuses are popular, casinos’ management sees them as a marketing cost for the business. The reason for this is that the online casino industry is so competitive that they often compete with several dozen others for the same players. So, each casino tries to outdo the other by offering more generous welcome bonuses, but often with more stringent policies tied to them.
Then there is also the fact that these terms and conditions are meant to protect the casino from players who try to cheat the system. Before you can claim the casino’s welcome bonus, you’ll need to meet specific wagering requirements. Generally, these are set to be 10x the bonus amount before you can withdraw it. For example, a 10x rollover would mean that you’d have to wager NZ$1,000 before you could withdraw the bonus.
However, there can be other stipulations like how much you decide to deposit into your wallet at the casino. This is a lot like buying chips at a regular casino.
Before a player can withdraw their welcome bonus, it is mandatory to meet the casino’s wagering requirements. Casinos have different wagering requirements, with a few only counting some games. Typically, table games and live casino games contribute a small percentage towards the wagering requirement. However, if you’re using the bonus to play slots, you can withdraw it when you reach the required wagering amount.
The wagering requirement is usually around forty times the bonus amount. Again this will vary, so make sure you check the details of your casino’s policies before you decide to deposit.
The casino’s promotions page usually lists all the requirements you need to meet for each promotion. If you still cannot find the wagering requirements for the welcome bonus, consult the terms and conditions or contact their customer support.
When you sign up at an online casino in NZ, you can often claim a sign-up bonus. This is usually extra money to play with, often for games like slots. But keep in mind, you might not be able to use the bonus on every game. To claim it, you’ll usually need to deposit at least NZ$25 and meet the wagering rules before you can withdraw any winnings.
Also, some casinos require you to use the same payment method for both deposits and withdrawals. So, if you deposit with a credit card, your winnings will go back to that card. That’s why it’s important to check the casino’s banking options before you deposit—some bonuses only work with certain payment methods.
Before you cash out, the casino might also ask you to prove your identity. This is normal and part of NZ’s rules to prevent fraud. Just be ready to show ID when asked—it helps keep things safe for everyone.
Now that you know what a welcome bonus is, how it can be used, and its various benefits, let’s quickly jump into our list of the best welcome bonus casinos in New Zealand. Not only are these casinos reputed, but they also offer an excellent welcome bonus which is pretty easy to comprehend and benefit from, unlike some of the others you may run into.
This casino gives first-time players a NZ$750 welcome bonus plus 200 free spins. It’s a solid offer—though not the biggest out there. That said, the bonus terms are fair and should be easy for most Kiwi players to meet.
This casino offers a NZ$100 welcome bonus and 100 free spins. On top of that, Kiwi players can enjoy fast payouts and a quick, hassle-free sign-up process.
The NZ$1500 welcome bonus is one of the most impressive we could find. Plus, players get to enjoy 150 free spins and fast payouts.
Players can get up to a 150% welcome bonus by depositing up to NZ$200. The casino features live casino games, along with all the favourites like slots, bingo, carps, etc.
Players at Sons of Slots get a 150% welcome bonus up to NZ$300. The casino also offers fast payouts and an easy sign-up process. One of the best things for Kiwi players is that the bonus terms are simple and easy to follow.
As mentioned earlier, some casinos may limit their sign-up or welcome bonus to a few types of games. Some games even have exclusive welcome bonuses. Generally, the welcome bonus applies to online pokies and bingo. However, they may not apply to table or live dealer games.
Kiwis love playing online pokies, not only because they are fun but also because they are convenient. Many of them come with free spin bonuses, and they are often a part of both the no deposit bonuses and deposit bonuses. Sometimes they may even be tied to a single title.
Bingo is every New Zealander gambler's favourite game or most people's favourite game. It can be played in many social situations, and has evolved from its offline counterpart. However, many of the bonuses offered to apply to online or virtual bingo. Many, if not all, sites also allow Aussie players to play real money games with the no-deposit sign-up bonus.
Live casino is a fun way to use your bonus, with a wide range of games like blackjack, roulette, baccarat, and live game shows such as Monopoly Live and Crazy Time. The only downside is that live casino games usually count only 10% toward meeting bonus wagering requirements, while pokies or slots count 100%, making them the faster option for clearing your bonus.

Most casinos don’t allow you to play live casino games using the welcome bonus. However, the few casinos that do will only allow a percentage of the bet from the welcome bonus to count towards your wager. This practice is called game weighting because they apply weighting percentages between 5-8% for live casino games.
So, if you are wagering NZ$10, only $0.05 may be deducted from your wagering requirement with a 5% weighted game.
We wouldn’t say that it is free cash. No deposit bonuses are free credits which means that you can use them to play various casino games. However, the only way you are allowed to convert these credits into cash is to qualify to withdraw them. That means completing the bonus wagering requirement, and this may mean playing through the value of the bonus as per the allotted requirements. So, familiarize yourself with the casino’s wagering requirements.
We have a list of the best welcome bonuses offered by online casinos in the previous section. We continue to update the list with casinos offering better welcome bonuses.
Yes! Most casinos will allow you to play progressive jackpot since the wins are paid from a large networked prize pool which means the minimum financial risk for the casino. That’s why most casinos will allow you to play this and other similar games. Some casinos offer free spins on popular progressive games like Mega Fortune Dreams and Mega Moolah.
