At the 200-strong party minors freaked out after encountering police.
Earlier this month, nine arrests were made at the party in North Coast of Auckland.
The owner of the council in the center of Takapuna would not have alcohol on site after the lease was rented.
"The police have been confronted with about 200 drunk people, a few minors who opened the police," the police said.
"Nine people were arrested, and the areas of Takapuna CBD were closed for over an hour when the police attempted to order."
In the pre-planned incident, alcohol consumption under the age of 18 initiated a police and municipal investigation, possibly under a ban on liquor trade.
The police have used the illegal party as an opportunity to remind the legal responsibilities of parents and carers while hosting the events.
"Remember that you are responsible not only for your own child, but also for the welfare of every child or young person involved in this event."
NZ Police's alcohol basics:
• Parents or guardians:
• He should be held accountable for the amount of drink under the age of 18 years.
• Checking amount and what you drink.
• Ensure that people under 18 do not drink too much, eat food, drink water, and are physically and emotionally safe.
• Being on the top floor is not considered to be supervised or responsible for watching movies or being with their friends.
• If you are happy as a parent or guardian for an alcoholic party of less than 18 years of age, you must allow the adult responsible for your child and responsible for that party.
• Speaking directly with this person and asking a question is a good sign of the type of party you are allowed to join.
• If you are organizing a party for minors under 18 years of age, or if you are under 18 years of age in a party that you own, you may be charged if you have been out of control and drunk under the age of 18.
• You can still be charged because the adult in the party doesn't matter whether or not the ones below the age of 18 bring their alcohols.
• It is a crime to give alcohol to those under 18 who are not yourself.
• It is an offense to be held responsible for a party that is under 18 years of age.
