When responding to incidents , or executing planned operations , AOS officers utilise both standard marked and unmarked cars , and large four-wheel drive vehicles , such as the Nissan Patrol . These are fitted with running boards and roof rails , to allow officers to stand on the side while the vehicle is in motion , as well as having enclosed boxes on the roof for carrying equipment . In 2009 , two New Zealand Army LAV III light armour vehicles were utilised in response to the 2009 Napier shootings
