Fire crews will work through the night as they battle a blaze near Palmerston, north of Dunedin.
A Fire and Emergency New Zealand spokesman said they were called at 8.49pm to a fire of an undetermined size, but it was "quite large."
Three helicopters and 10 fire trucks were initially sent to the fire - at a rural property on Chalmers Rd, Bushey - which was burning through pine trees and slash - debris from removed trees.
Two appliances each from Palmerston, Waikouaiti, Hampden, Kakanui and Waitaki rural were called.
Two additional appliances from Dunedin and Weston were called to assist after 9.30pm.
The helicopters were stood down as the sun set.
As of 10.15pm crews were still tackling the blaze, and would continue to do so all night, the spokesman said.
