Different Types of Online Casino Bonuses in New Zealand

Now that we have taken you through some of the top-quality NZ casino bonus codes, this guide will now take a look at some of the various online casino bonuses that can be found at online casinos that are truly serious about the business that they are in.

Online Casino Welcome Bonuses

Online casino welcome bonuses, also known as first time deposit bonuses, are a kind of bonus that you will be treated to when you opt to sign up with a particular online casino. Such bonuses will usually be in the form of a match deposit, with your first deposit and sometimes your second, third, fourth and fifth deposits being matched to a certain value. Some online casinos, as you have seen above, will also throw in some bonus spins as well.

No Deposit Bonuses

This is a kind of bonus that you can claim without the need to deposit any money straight away. All that you have to do is register with the casino and you will receive whatever bonus it is that they are offering. Casino players love this kind of bonus as it allows them to try out the site without having to commit financially to it. If you do not like the online casino, for whatever reason, you can just leave without needing to think about withdrawing your deposited cash.

Since there is no need for a deposit to claim such a bonus, you will not be surprised to hear that no deposit bonus codes do not exist. You can find out some top no deposit bonus casinos by following this link.

Free Spin Bonuses

Free spin bonuses allow you to spin some slot reels without having to spend a single cent. Your bonus spins will usually be for a certain game that your online casino is looking to promote. Free spins usually have a certain value, and you will have a maximum amount that you can win - we will discuss this more in our T&Cs section later on.

Reload Bonuses

These are also known as loyalty bonuses as they are given to those players who are most loyal. When you play regularly with them and spend plenty of money, you might get a notification telling you that if you make another deposit, you will receive some bonus money on top of it.

How to Use Online Casino Bonus Code

In this next section of our guide, we will explain all you need to know regarding how you go about using any online casino bonus code that you come across.

Choose Casino Bonus

Obviously, you first need to find a casino bonus that you would like to claim. We have given you six top options above, but you are certainly more than welcome to do some of your own research if, for whatever reason, none of the six online casinos are that appealing to you.

Sign Up

When you have found the perfect welcome bonus for you, the next step is to open an account with the online casino NZ in question. You will need to give them some of your private information like your first name, last name, date of birth, house address, email address, and mobile number. You will need to come up with a unique username and a password that is not easy to guess.

Use Bonus Code

Once you have created your new online casino account, you will need to go to the payment options page so that you can deposit some playing funds via your preferred payment option. Follow the easy deposit instructions and add the required bonus code in the relevant box. If you do not do this, you will miss out on the bonus.

Start Playing

Once your deposit has been processed, you will get the bonus and will be able to start trying your luck on their games.

Best Games to Play at Online Casinos in NZ

There are plenty of different game types that you can find at the top NZ online casinos, and now we are going to have a look at some of the best games available to us New Zealanders.

Online Pokies

Pokies, more commonly called slot games outside of New Zealand, are the most popular type of casino game since they do not take a lot of intellect to learn how to play. Additionally, they have plenty of entertaining bonus features and give us the chance to land some big money prizes for small playing fees. The most popular pokie type are progressive jackpots as these come with a jackpot that keeps on growing until someone wins it. Below you can see some of the best progressive slots around:

  • Age of the Gods
  • Mega Moolah
  • Treasure Nile
  • Major Millions

Online Poker

Poker is one of the world's most popular card games, so it is not surprising that it can be found at most online casinos that are happy to accept Kiwi players. Most card games rely on complete luck, but poker is different as you need skill if you want any real success when playing. You can see some popular poker variants below:

  • Texas Hold'em Poker
  • Omaha Poker
  • Omaha Hi-Lo
  • Seven Card Stud

Online Roulette

Even if you have never played at a land-based or online casino before, we are pretty sure that you know what roulette is. Even if you do not know the name, you know the game for sure - it is that game where a wheel is spun, and you have to predict where the ball will stop. Things are kept entertaining by the fact that there are plenty of different bet types that you can put your money on. Some top roulette variants include:

  • Slingshot Roulette
  • Double Ball Roulette
  • European Roulette
  • French Roulette
  • American Roulette

Online Baccarat

Online baccarat is really popular due to its simplicity. The dealer will place two cards down in one pile and two cards down in another - one pile is called the "Player" and the other is called the "Banker". You then need to try and guess which hand has a value that is closest to nine. You can see some popular variants of baccarat below:

  • Speed Baccarat
  • No Commission Baccarat
  • Lightning Baccarat
  • Mini Baccarat

Online Blackjack

Blackjack is a popular card game where the main aim is to build a hand as close to the value of 21 as you can without going over. When every player has played during a round, each hand will be compared with the dealer's hand, and the higher one is the winner. If your hand value goes above 21, you will go bust. If you land a blackjack, your payout will be 3:2. Below are some popular variants of blackjack:

  • Double Exposure Blackjack
  • Blackjack Switch
  • Classic Blackjack
  • Multihand Blackjack

Online Craps

Craps is a quick-paced dice game which has bets that suit all kinds of gamblers. The aim of craps is to guess the value of the next roll of the dice. At first, this game might look complicated, but looks can be deceiving and it is easier to learn than it seems. Additionally, there are some top payouts available if your luck is in. Below are some popular craps variants:

  • New York Craps
  • Crapless Craps
  • Die Rich Craps
  • High Point Craps

N.B. All of the best NZ online casinos will offer their players the option of playing their casino games in demo mode. We suggest that you do this as it allows you to learn about the different games without having to spend money to do so. However, since you are not spending any money, you will not win any real money.

Casino Bonus Terms & Conditions

All of the bonuses that you will come across in the New Zealand online casino world will have several terms and conditions attached - an online casino is not just going to hand out completely free money to anyone who signs up with them as they would be out of business within a week. It is wise to get into the habit of reading the terms and conditions that are attached, so in this last section of our bonus codes deposit guide, we are going to look at the major terms that you will find attached to most bonuses.

Wagering Requirements

The wagering requirements that you will find attached to a promotion tell you the amount that you will be required to spend before the bonus money and any winnings made from it are available for you to withdraw. For instance, the bonus at Lucky Dreams has a wagering requirement of 40x, meaning that if you decided to deposit $50 and got $50 worth of bonus money alongside 100 free spins, you would have to wager $2000 before bonus and any winnings can be withdrawn.

Maximum Win

Sometimes the online casino will put a limit on how much you can win from any of the free spins that you have landed. For example, you might be informed that there is a $300 max win limit, which means that if you were to win $400 from your free spins, $100 of that would go back to the online casino. However, not all online casinos have maximum win limits. For instance, Katsubet currently offer unlimited wins from their bonus money and spins.

Minimum Deposit

Unless you have come across a no-deposit bonus, you will have to deposit some money in order to claim some part of the bonus, and there will be a minimum amount that qualifies you for the said bonus. For instance, the min deposit at Mr Sloty is $20, the min deposit at Katsubet is $40, and Lucky Dreams Casino has a minimum deposit of $30 for their bonus money.

Payment Method Restrictions

You will often be able to claim the bonus that is being offered by depositing with most banking options, but there are three that most online casinos will not accept for this matter, and these are Skrill, Neteller, and PayPal. This is because players, in the past, have used these payment options to claim the same bonus multiple times, so they have now become blacklisted.

Game Restrictions

The bonus spins that you receive will usually be available only for specific pokies - you might come across the odd free spins bonus where the spins can be used on any slot game, but these are very rare. Usually, it will be for a pokie that your selected online casino is looking to promote. For example, the free bets that you can claim at Katsubet Casino can be used on the Wild Cash x9990 slot game.


If you believe that your bonus money and bonus spins will last until you decide to use them, then we have bad news for you, our friend. Your selected online casino will only give you a set number of days to make use of your bonuses before they expire. For example, the bonuses that are on offer at Lucky Dreams Casino and PlayFina Casino will expire after a total of seven days. If you forget to spend the bonus money or use the bonus spins in this time frame, you will forfeit the lot.

Betting Limit

If you receive a bonus of $100, you might think that you have the option of slapping it all down at once in order to try and land some big winnings. However, this is not the case since online casinos will usually install a maximum betting limit to prevent you from doing this. For example, at Playfina Casino, the maximum bet for all types of games stands at $6.50.


Which Online Casino Has the Best Welcome Bonus?

Well, this is very subjective since not every player will be searching for the same sort of bonus. A huge welcome offer with 50x wagering requirements might be manageable for some players, but less manageable for others. Some of the top welcome offers that we have found have been listed below:

  • LuckyDreams Casino - Up to $10000 and 500 free spins
  • Katsubet Casino - Up to $6000 and 200 bonus spins
  • Mr Sloty Casino - Up to $6000

Which Casino Has a No Deposit Bonus?

No deposit bonuses are very enticing to online casino players as they give us the chance to test out a site that we like the look of without needing to commit our own hard-earned money. However, deposit bonuses are much more common. We have managed to find a no deposit bonus casino for you though, and it goes by the name of Amazon Slots - they are currently offering 20 free spins on Sweet Bonanza to anyone who registers an account with them.

Which Casinos Give Free Play to New Members?

No online casino free money to new members, and it is important to keep this in mind. You will always find T&Cs attached to any monetary or free spins bonus that you get from an online casino. This is why it is very important to read the terms closely before you go and claim any kind of bonus.

What is a Casino Promo Code?

A casino promo code is a series of letters and sometimes numbers that you will have to add to a box when you are depositing a bonus at an online casino. If you do not add the bonus code to the relevant box, you will not receive any of the bonus that is being offered.

How Do I Redeem a Bonus Code?

Once you have come across a welcome bonus that you like and would like to claim, there are several steps that you will have to follow to claim it. The first thing you will have to do is sign up with the online casino by giving them your first name, last name, date of birth, house address, email address, and mobile number. You will then be required to create a unique username and strong password. Then, you need to go to the payments page and make a first deposit - there will be a box where you must enter the given bonus code. Once the deposit has been processed, you will receive the bonus on offer.
