Multiple fire crews and two helicopters are battling a 30 hectare blaze in a North Canterbury forest.
The Fire Service was called to Balmoral Forest, north of Culverden, at 3.22pm today.
Spokesman Riwai Grace said conditions were very dry, with strong winds.
He said anyone in the area should listen to police or fire service advice about their own personal safety. This sort of fire could travel quickly, he said.
