Firefighters spent several hours trying to extinguish a fire in a Western Bay of Plenty home that was reported to have been deliberately lit.
Police and fire crews were called to the blaze on State Highway 2 near Tahawai in Katikati at 9.30pm on Saturday.
Katikati fire station officer Brendan Gibbs said firefighters spent hours trying to put out the fire and dampen hotspots.
"We did not get home until 1am," he said.
"The house was quite seriously damaged. I don't think it is repairable."
