Why Trust Mr.Gamble?

The online world is very often a treasure, but not everything you stumble across is trustworthy. Our team of experts were casino players once, and we know how frustrating it is when you cannot find reliable information or, even worse, rely on incorrect facts.

So, we base our company on integrity, objectivity, and independence. Here, you can only find the best gambling sites in New Zealand, and we make sure we leave no stone unturned when we review each of their aspects!

What Is a 400% Online Casino Bonus?

Now that you know which are the best online casinos with 400% deposit bonuses, we need to take a step back to the basics and explain how a 400% casino bonus works exactly.

The description could not be any simpler: a 400% deposit bonus will boost your deposit four times, hence giving you more money to play with and eventually quadrupling your potential winnings.

For example, a 400% match deposit bonus can go as follows: if you deposit NZ$100 and claim a 400% deposit bonus casino offer, then you will receive an additional NZ$400 to play with, so you will now have NZ$500!

Bonus Terms and Conditions of a 400% Deposit Bonus

Before you claim any casino deposit bonus, you need to know all about the rules for using it. For that reason, never skip the terms and conditions. Even though they can be quite extensive at times, T&Cs contain valuable information about the bonus, such as:

  • Minimum deposit: All casino bonuses have minimum deposit amounts you need to respect if you are to claim the offer. Usually, the first deposit bonus will have a higher minimum deposit amount compared to the 400% match bonus offers you might get later on in your gambling journey.
  • Eligible games: Not all casino games may be eligible for the 400% promotion. Sometimes, the bonus is meant for online pokies, while many online casinos may incentivize you to try out their live casino games with the 400% bonus.
  • Game contribution: Not to be confused with the eligible games, the game contribution describes what percentage games contribute towards the wagering requirements. Most online casinos make pokies contribute 100% towards the bonus.
  • Duration: Bonuses are not valid forever, so you will have a predetermined time in which you will be able to use them.

Armed with that knowledge, you can make the most of your bonus and never be disappointed!

400% Bonus Wagering Requirements

Many people consider wagering requirements to be the most crucial component of any casino offer, and it is difficult to argue with them. It is also known as a playthrough or rollover requirement, and it indicates the number of times you must wager the bonus amount before you may withdraw your bonus winnings.

How We Rate 400% Online Casinos

We mentioned a couple of times that we are independent and honest with our bonus and casino reviews, but what methodology do we use? Our research is quite extensive, but our approach revolves around four basic principles.

🔒 Licence and Security

A valid licence from a trusted regulator is the bare minimum a 400% casino must have. Such a licence will guarantee that players gamble on a secure platform, and they can feel free to provide personal and financial data. Most casinos we recommend integrate SSL encryption protocols that scramble the communication between you and the casino, so all your transactions are 100% secure!

🎁 Bonuses and Promotions

Since we talk about 400% bonus offers, we take a look at whether there is such a section, but that is not all. Alternative bonuses and fair terms and conditions are also a necessity if the casino is to find itself on our list.

🃏 Game Catalogue

At the end of the day, online casino games will make or break your online gambling adventure. Online pokies, table games, and live dealer games from the leading game providers on the market are what we look for!

💵 Payment Methods

It is important that you find your preferred payment method whenever you gamble online, so we have to check whether the casino has integrated the most popular ones. Credit/debit cards and e-wallets lead the way in terms of popularity among Kiwis, so those are always our starting points.

How to Claim a 400% Bonus

The vast majority of the 400% bonuses you will get come as part of the welcome package new players receive. So, there is a certain process that you need to follow when you claim the 400% casino bonus as a new player. Let's check it out.

Step 1: Choose a Casino from Our List

Since you know our methodology for choosing top online casinos, you wouldn't make a mistake by choosing one from our list above. All operators are 100% secure and reliable, so check the fine details, see which casino matches your gaming style and preferences, and choose!

Step 2: Create an Online Casino Account

Now, you need to click on the "Register" or "Sign Up" button on the website and provide the necessary personal information. This is a process that doesn't take more than a couple of minutes to get done, given that you provide the correct information.

Step 3: Verify Your Account

One of the security measures casinos take to eliminate fraudulent accounts is the verification process. Once you register, you will instantly receive an email with a verification link. You just need to click on that link and verify your account before proceeding to the next steps.

Step 4: Make the Initial Deposit

Each 400% bonus will require you to make the qualifying deposit if you are to claim it. So, here, you need to choose your payment method and deposit funds into your account. Deposits should be instant, and no fees are attached.

Step 5: Claim the Bonus

The fun can now begin! Check whether you need to enter bonus codes to claim the offer, and let the fun begin! See the eligible games and start spinning! Hopefully, it won't be long until you secure your first win!

Online casinos offer 400% bonuses in various forms, but that is good news for each punter. It means that you can expect such a bonus at every stage of your gambling journey, and they will be designed to fit all gambling habits of punters.

400% Welcome Bonuses

An amazing 400% welcome bonus can be the exciting start of your gambling adventure that you seek! Casinos know that new players are incentivized to register with large bonuses, and the 400% offer is exactly that!

Our research has shown that, usually, online casinos will split the maximum bonus money into your first few deposits. You won't get the entire offer at once, so you can maybe expect a 100% deposit match bonus for your first four deposits. In addition, don't be surprised to see a few free spins thrown in the mix, making the welcome offer a very rewarding and large casino bonus!

400% Bonus for Online Pokies

Online pokies are arguably the most played category of games among Kiwis, so casinos normally seek to capitalise on that popularity. Therefore, during our research, we stumbled upon 400% bonuses for online pokies, in particular.

Even with the first deposit bonus offers mentioned above, only online slots contribute 100% towards the wagering requirements, so you can see their importance with these promotions.

400% Bonus for Live Casino Games

Live dealer games grow in popularity among Kiwis with each passing year. For many, there is no better feeling than experiencing the thrills of a real casino, and live dealer games take you as close as possible to the real Vegas action!

Since these games are run by real dealers and streamed in real time from studios around the world, you can just imagine the excitement when playing with a 400% bonus! Well, you'll be happy to know that you can even claim a live dealer 400% bonus at selected few online casinos.

Pros and Cons of 400% Deposit Bonuses

We wouldn't blame you if you thought that 400% deposit bonuses are perfect and that you should always jump in to claim them. However, there is no such thing as perfection in the online gambling world, so as objective as we are, it is our responsibility to warn you about some minor drawbacks of bonuses that will quadruple your deposit.

New 400% Casinos in New Zealand

New online casino sites hit the NZ gambling scene all the time, so it is our duty to keep you updated at all times. Moreover, new casinos tend to be more rewarding with their bonuses and have more user-friendly T&Cs in a quest to attract more punters to register.

So, let's take a look at some new gems in the online casino world offering 400% bonuses!

Payment Methods at 400% Casinos

Besides bonuses and games, payment methods are the third vital pillar that will determine the success of any online casino. Since online gambling is a very popular pastime activity in New Zealand, casinos need to adhere to the needs of Kiwis and have a versatile payment methods section. In that line, the most common options we encountered at 400% bonus casinos are:

Credit/Debit Cards

A widely accepted payment method would be a Visa or Mastercard credit/debit card. These options offer 100% secure and simple payments, but withdrawing your bonus winnings can take up too much time when compared with cryptos and e-wallets.


If you seek a faster alternative to withdrawing winnings, then e-wallets such as PayPal, Skrill, and Neteller are your choices. The best online casino sites offer these payment methods, and you can top them up with your credit/debit card before you use them for gambling.

Prepaid Vouchers

Neosurf and paysafecard come to the top of our minds instantly when speaking of prepaid vouchers. You can purchase them at tonnes of retail stores in New Zealand, but you can only use them for deposits. So, you need to rely on another option for withdrawals.


At last, cryptocurrencies seem to have all the advantages of the rest of the payment methods mentioned. Due to their decentralised nature, the likes of Bitcoin, Litecoin, and Ethereum offer instant, anonymous, and free transactions!

400% Bonus Alternatives

We don't want you to think that since we appreciate 400% deposit bonuses that we ignore other generous offers. Our suggested operators never rest on their laurels, so they make sure to keep you engaged with other rewarding promotions:

Quadruple Your Bankroll and Secure Jaw-Dropping Prizes!

Hopefully, this article has been helpful in showing you the benefits and potential 400% deposit casino offers! The exact maximum bonus value and the general terms and conditions can vary from one operator to another, but our suggested casinos offer you this exciting bonus with a low minimum deposit and a wide range of eligible games.

Now all you have to do is sign up with one of the casinos on our list, make a deposit, and get your hands on the thrilling 400% deposit match bonus!


Are 400% bonuses worthy?

Given that you are okay with the T&Cs (wagering requirements, minimum deposit, etc.), 400% bonuses have a lot to offer, and we would advise you to claim them when you stumble across them at a reputable casino.

What is the best 400% casino in New Zealand?

Thankfully, there is no universal answer to this question! As you can see from our list above, there are several top-class 400% bonus casino sites, so take a look, apply your own filters, compare, and choose accordingly!

How fast can I withdraw my bonus winnings at 400% casinos?

This is primarily determined by the payment form you select. Withdrawals from cryptocurrencies and e-wallets are typically much faster than those from credit/debit cards.
