While investigating a truck fire thought to have been deliberately lit, police came across a property with 12 stolen vehicles in the backyard.
The drama unfolded on Sunday morning when a pig hunter headed back to his truck after a couple of hours hunting at Pipiwai, northwest of Whangarei.
He heard loud booming noises and as he got closer to the vehicle, realised fire had engulfed the truck.
Police officers from Kaikohe were called and visited properties in the area to see if they could locate any witnesses. They came across a property about 3km away and noticed a vehicle with no number plates.
Detective Constable Shawn Parker said that while searching the property, they discovered a large number of vehicles that turned out to have been stolen.
