Criminal Investigations (Bodily Samples) Act 1995, ss 18, 21
If you’re under 18, there are some additional rules about when a judge can order you to give the police a DNA sample and about the process for this:
The type of offence – The criminal offence that you’re suspected of must be one that you could legally be charged with at your particular age (see youthlaw.co.nz for more information).
Notice to your parents – Your parents have to be given a copy of the application.
Who can go to the court hearing – The following people can go to court and give evidence to oppose any compulsion order being made: you; your lawyer (if you don’t have your own lawyer, the judge will appoint one for you); a non-lawyer with mana or standing in your community who’s been appointed by the Youth Court to give you support (called a “lay advocate”); your parents and their lawyer; and anyone else who gets the judge’s permission to be there.
