The legal age to buy alcohol in NZ is 18 years old.
If the police find you drunk in a public place or trespassing on private property, they can take you into custody and either take you back home or to a shelter if they think you:
- may be at risk of hurting yourself or others; or
- are unable to protect yourself from harm; or
- are likely cause a large amount of damage to any property.
The police must release you as soon as you’re no longer drunk. They must not keep you in custody for longer than 12 hours.
