Crews fought the fire through the night and all day on Tuesday
Two helicopters assisted, using monsoon buckets to fight the spread of the fire.
Four rural fire brigades with six fire trucks were called in as well as two tankers and three pumps from the Whanganui Fire Station.
The steep hill made it hard for the fire to be reached by vehicle.
“Due to the terrain, it’s quite difficult for our firefighters to actually access it.”
The fire was now under control but crews were still there on Wednesday “dampening down, mopping up and retrieving equipment”.
Additional crews were arriving from New Plymouth on Wednesday to assist and “check for hotspots”.
Although the fire was contained, crews were checking for anything that could cause further trouble, Dudley said.
