The scene of Saturday night's shooting in Morrinsville remains closed this morning as police continue their investigation into the shooting.

Police say they were fired on by a driver who earlier failed to stop for police. Police were attempting to pull the driver over for speeding.

The vehicle, a red Holden commodore that pulled over on Kuranui Road, and the driver got out and began firing at the police vehicle with what they believe is a military style semi-automatic weapon.

The officer took cover in nearby farmland and called for back-up. The offender continued to shoot at a second police patrol vehicle that arrived shortly after.

The two officers in the second vehicle returned fire at the offender before also taking cover. The area was quickly cordoned off and the Waikato Armed Offenders Squad arrived to safely retrieve the three staff from the area.

The scene examination at Kuranui Road and is expected to be completed later today, says Detective Inspector Graham Pitkethley.

The focus of the investigation team continues to be on locating the offender and Waikato Police are being supported by staff from other Police districts.

Police located and are speaking to two occupants of the offending vehicle, a man and a woman, who are assisting with the investigation.

They believe the gunman was a third man in the vehicle.

'We would like to hear from anyone with information relating to the offending vehicle: a red, 2015 Holden Commodore, registration 1AZIF1.

'We would like to hear from anyone who has seen the vehicle in the area recently or has any information relating to it - no matter how small or insignificant you think it may be,” says Graham Pitkethley.
