Section 23: NZ Bill of Rights

These rights protect people who have been arrested or held in custody.

This provision says anyone arrested or detained must be treated with humanity and dignity. You have the right to know the reason for your arrest or questioning, and to be given the chance to talk to a lawyer.

These rights are to ensure that detention doesn’t become an abuse of power. 

If you are arrested in New Zealand, the standard advice is to stay calm, and use your right to silence to not answer questions beyond giving basic information such as your name, address and date of birth. You should ask to speak to a lawyer privately. The Police Detention Legal Assistance (PDLA) scheme also provides free legal advice, even over the phone.
