The Department of Internal Affairs is the governing body for the casino laws in New Zealand. They issue licenses and certificates to all land-based casinos here in New Zealand. There are six casinos operating here and all of them are being regulated and monitored to ensure that that they comply with all the laws.
Manage and minimize the disadvantages that are caused by gambling

Gambling is a game where you bet that your instincts are better than the other. And that means that one side will earn money and the other will lose. And for those who will be losing money, it would mean financial ruin followed by depression, anxiety and mood disorders. So, it has become important for the government to reduce these risks.
Educate gamblers about responsible gaming

To ensure that gambling remains a healthy recreational and exciting activity it is important that education is provided. Gamers should understand how gambling can financially and emotionally affect them.
Guarantee the players a fair chance of winning

Casinos can easily manipulate their tables and machines to make sure that they make money all the time. However, casinos cannot operate if they do not also give the gamblers a fair chance of winning. Gambling can only really flourish if there’s fairness in the games.
Remove the criminal groups or syndicates in all gambling establishments

Since gambling involves a lot of money it is unavoidable that it will attract criminals and syndicates. All criminal activities involve dishonest games and/or fraudulent transactions and so the government is taking a strong stand in curbing them.
Manage the growth of the gambling industry

The growth of the gambling industry has to be managed as well to guarantee that enforcement can be done efficiently and regulations are updated accordingly.
Encourage the industry to have community responsibility

Casinos and resorts can quickly grow a community by providing the locals with much-needed work and revenue.
The increased tourism will also increase activities and create more opportunities so it is vital that casino resorts also take care of their own communities and guarantee that a good portion of their revenue goes to local development.
Control the allowable gambling activities

The Department of Internal Affairs also controls what games casinos are allowed to offer and this further ensures that gambling remains fair and activities have reduced disadvantages.
It is important to note that New Zealand laws bear a close similarity to the laws found in the UK and France. For example, some of the basic laws in New Zealand like family laws were practically copied from the same principles that form the family core laws in the UK.
But over the years New Zealand lawmakers have made their own adaptation. For example, divorce is no longer allowed under the New Zealand family law even though the principles behind the family law came from the UK where it is legal.
