Police Act 1998

A police security officer may give a person within the vicinity of a protected vehicle reasonable directions for the purposes of maintaining or restoring security or orderly conduct at the vehicle or securing the safety of any person about to enter, in, or getting out of, the vehicle.

If—

a person refuses or fails to comply with a direction given by a police security officer under subsection (1); or

a police security officer suspects on reasonable grounds that a person has committed, is committing, or is about to commit, an offence in or within the vicinity of a protected vehicle, the officer may do 1 or more of the following:

direct the person to provide—

the person's name and address; and

evidence of the person's identity;

cause the person to be removed to some place away from the protected vehicle;

cause the person to be detained and handed over into the custody of a police officer as soon as reasonably practicable.

Reasonable force may be used for the purpose of taking action under subsection (2)(d) or (e).
