A biosecurity enforcement officer may, without a warrant:

  (a)   enter premises where a biosecurity industry participant carries on biosecurity activities under an approved arrangement, or a first point of entry; and

  (b)   exercise there monitoring and investigation powers like those under Parts   2 and 3 of the Regulatory Powers Act (as they apply because of Parts   1 and 2 of this Chapter).

Biosecurity officers and biosecurity enforcement officers entering premises without a warrant (under this Part or certain other provisions) must announce their entry and identify themselves, and may use reasonable and necessary force against things to enter the premises and while on the premises.

Occupiers of premises entered without warrant, and their representatives, may observe the exercise of powers there, and must assist.
