Police Powers and Responsibilities Act 2000

If a person is detained for questioning under this part more than once in any period of 24 hours and questioned for a total of more than 4 hours in the 24 hours, a police officer must not continue to question the person, unless the detention period is extended under section 406.

Example—If a person who has been arrested for a stealing offence and questioned for 3 hours is again arrested within a 24 hour period for a break and enter offence, a police officer can only question the person for 1 hour before being required to apply for an extension of the detention period.
