โญ Different Types of Casino Bonuses
There are several types of bonuses to real money casinos NZ, including the sign-up bonus, free spin, bonus spins, and welcome package offers. To make it clear what you get from casino bonuses, BonusFinder explains the different bonus types. Below you can find the different types of casino bonuses explained:
- Sign-up bonus
First deposit bonuses are the biggest and most common casino promotion, forming the basis of almost all welcome packages. They are also given to existing players, but then they are called reload bonuses. The deposit offers are tied to how much you deposit, calculated from the match-up percentage (match bonus) and limited by the maximum bonus amount. - No-Deposit Bonus
Online casino players always get brilliant no-deposit bonus offers. You get free spins and bonus money to play games from different casino game providers. Microgaming is a must-have for jackpots fanatics, Evolution Gaming rules the live casino, and NetEnt has some of the hottest and most played games around. - Extra Spins
Extra spins, often erroneously called free spins, are real-money spins you get when you deposit and are for selected games, typically online slots games, and they have the least terms and conditions attached to them. Another great thing about these spins is that you often get them with a match-up bonus. Free spins no deposit NZ offers are especially great when playing jackpot games with them โ win big without putting your money in! - Existing Players: Loyalty Bonuses & VIP Bonus
Existing casino players also get various extra rewards as loyalty bonuses and via a VIP scheme. Most online casinos have a rewards program that allows you to collect bonus points. If you stay loyal to a casino, you can get VIP treatment. Bonuses from a VIP program are mostly extra free spins, cash prizes, deposit bonuses, or a chance to exchange your VIP points for cash. - Deposit lotteries
Besides spins and extra money, casinos often run different deposit lotteries. Typically they work so that your deposit is a ticket for a draw, where you can win something fun. As deposit lotteries are standard at online casinos, the prize is almost always the latest iPhone when a new iPhone model comes out. - Cashback
A cashback reward program is an incentive program operated by online casinos where a percentage of the amount spent is paid back to your casino account. - High roller bonuses
High rollers are players with big gambling budgets and players who are looking to gamble with high stakes. We have a couple of exclusive casino bonus offers for big money games. - 200% Deposit Bonuses
Some casino bonuses triples your deposit. These 200% match bonus casinos NZ are hard to find. We’ve listed the best casino sites offering these valuable welcome bonuses. - Bitcoin Bonuses
In 2023, some casino offer bonuses for gamblers that pay with cryptocurrencies, such as Bitcoin. You’ll find bitcoin casinos offering anything from free spins to match-up offers or free cash on sign-up!
โญ Bonus Terms & Conditions Explained
Before you claim an online casino bonus, it must be that you read the T&Cs attached to the bonus offer. In 2023, online casinos are always required to make their T&C’s very visible and easy to read. They are usually quite similar, but some differences make some bonuses worth it more than others.
We explain the most common terms & conditions casinos attach to their free spins, bonus money, and other bonuses. Every offer we have on the site can be used on a mobile casino. Most often, bonuses exclude live casino games. While the rules don’t make it impossible to win, they limit what you can and can’t do while playing with your bonus.
Wagering requirements:
The most common limitation attached to casino bonus offers (especially welcome bonuses) is a wagering requirement. It dictates how many times you must wager your bonus before you can withdraw them. Both the winning and losing rounds count towards wager requirements.
Until you have cleared your playthrough requirements, your wins are locked in a bonus balance. Most online casinos have a wagering requirement of 30 to 50, but then there are low wagering casinos with requirements less than 20x and no wagering casinos with 0x.
Maximum win:
Always check the bonus terms and conditions. Some NZ casinos limit the amount of money you can win when you play with casino bonuses. As annoying as this sounds, it’s a way to protect themselves, and it’s enforced chiefly on no-deposit bonuses.
Minimum deposit:
Often, casinos attach a minimum deposit amount to every deposit bonus type they offer. You can get excellent match deposit bonus offers with a minimum deposit of $1, $10, $20, $50. These casino bonus deals could be even more valuable to you than some free spins no deposit casino promos. For example, most of the $20 minimum deposit casinos have a 200% matched bonus on your first deposit.
Payment Method Restrictions:
You might not be eligible for the casino bonuses with specific payment methods (usual e-wallets such as Skrill and Neteller) at real money casinos. Always make sure you can receive the bonus before you make a deposit.
Game Restrictions:
Usually, there is a prechosen list of slot games you can play with free spins and sometimes also deposit bonuses. Moreover, not all games count towards the wagering requirement and not all casino games contribute equally to the wagering requirement.
Most table games and video poker are often off-limits; some casinos limit progressive jackpot slots as well. The game selection options you have are primarily due to the high return to player (RTP) of these casino games.
Expiry:
Make sure your bonus offers won’t expire. Most casinos require you to cash in your bonus credit and meet the wagering requirement in a specific time frame. Casino bonuses are usually only available during your first week after registration, while for other bonus types, it is usually 30 days.
Betting Limit:
When you play with bonus money, you should keep an eye on your T&Cs. All casinos limit how much you can bet with your bonus funds. When playing with cash rewards, the maximum bet size is tied to your deposit or bonus value most of the time.
For example, the max bonus bet could be 10% of your deposit. Sometimes it’s a limitation on how much you can bet per spin (NZ$5). If you wager more, you’ll be in breach of terms & conditions and can’t cash out your winnings.

-
No matter how big you hit, your online pokies and table casino games winnings are always tax-free in NZ. Taxes aren't a problem as non-professional gambling winnings are not taxed. So even if you hit a multi-million jackpot on Mega Moolah, Inland Revenue will not touch your spin winnings.
