An independent investigation into the shooting of an armed gunman by a police officer has found that the officer's actions were justified.
The Independent Police Conduct Authority has released the ruling details into the December 2017 incident.
Authorities were called to a campground in the Manawatu after reports of a man behaving erratically and who was threatening his partner with a sawn-off rifle.
Other people at the campsite called police and the Armed Offenders Squad was called out.
The details show that four AOS officers only approached the man when he entered a campervan where several campers had taken refuge.
