Two fire trucks, a water tanker and a van from Dannevirke attended. They were supported by a fire truck and a tanker from Norsewood and a truck from Woodville. Members of the Takapau brigade were on stand-by in Dannevirke.
Sinclair said all up 20 fire personal were at the scene.
The house was owned by the sole occupant.
Sinclair said the house contained working smoke alarms, which woke the home owner and alerted him to the fire.
"He tried to do what he could to put out the fire but fire comms, who he was in contact with, told him to get out of the house and stay out."
He said it was very difficult for the owner to have to stand by and watch his home burn.
He was in no doubt the smoke alarms saved his life.
Firefighters stayed at the scene for several hours, keeping an eye out for hot spots and dampening them down, before returning to the Dannevirke station at 5.45am.
Sinclair said while the house was still standing, the back half was gutted and the rest of the house badly damaged by smoke and heat.
