He said the building had a brick exterior but the property had been totally lost to the fire, both the house and shed.
He said the first fire officer to arrive was senior station officer Peter Keenan, who quickly got the fire under control with his crew.
“Being a back section property, there are a lot of properties surrounding the building that was on fire,” Millar said.
He said the fire was being treated as suspicious at this stage.
One neighbour said she saw the property well ablaze just after midnight with a “massive” plume of smoke.
Specialist vehicles from Napier and Hastings were called initially, but not required.
A police spokeswoman said they maintained a scene guard overnight.
“Police will be making further inquiries,” she said.
Investigators were on the scene on Thursday morning to find the cause of the fire.
