Four Northland barn fires within hours of each other are being treated as suspicious.
The Fire Service called police after carrying out preliminary investigations into the fires at Graham Rd in Mangapai and at Stead Rd in Waiotira early yesterday.
About 3.15am, fire crews from Maungakaramea, Ruakaka, Portland and an appliance from the New Zealand Refinery in Marsden rushed to Graham Rd after three small sheds used as barns went up in flames.
Most of the contents in the barns were dry firewood and hay.
The buildings were destroyed by the time fire crews arrived.
