Law Enforcement (Powers and Responsibilities) Act 2002

A police officer may establish a crime scene on premises in any way that is reasonably appropriate in the circumstances.

A police officer who establishes a crime scene must, if reasonably appropriate in the circumstances, give the public notice that the premises are a crime scene.

A crime scene may not be established under this Part on the same premises more than once in a 24 hour period unless a crime scene warrant is obtained in respect of the second and any subsequent occasion.

Subsection (3) does not prevent a subsequent crime scene being established on the same premises in a 24 hour period for the purposes of investigating a separate offence that is not related to the offence in respect of which the initial crime scene was established.
