Police received a report around 9.20am from a man threatening to harm himself with a firearm. He was parked up in a 4x4 vehicle on Scotts Road, Linton.
Approximately 15 officers attended the relatively rural location and put a cordon in place. Negotiations by phone and verbally at the scene continued for five hours.
At approximately 2.50pm Police deployed tear gas which resulted in the man removing himself from the vehicle and being taken into custody without further incident.
A loaded semi-automatic 22 calibre rifle and ammunition were recovered from the vehicle.
The 36-year-old man from Palmerston North will appear at Palmerston North District Court tomorrow charged with firearms related offences.
