The occupants of the A framed unit, who were not at home at the time of the incident, lost most of their belongings in the fire.
George Nicholls, the chief officer at Fire Rescue Services, said they received the call regarding the blaze at 2.26pm.
Nicholls said by the time they arrived at the scene, the fire had completely engulfed the house.
However he said they managed to stop it from spreading to neighbouring properties.
Volunteers from the Puaikura and Teimurimotia fire brigades also came to the rescue.
Nicholls said they were fortunate to have one of their officers at the scene.
“Luckily he was there when the fire broke out and was able to direct the fire truck to the right spot which made it easier for the firefighters to keep the blaze away from reaching the neighbouring house.”
People living nearby said they heard a loud noise before the fire started breaking out of the building.
Nicholls said they wanted to cordon the area today and start their investigation into the cause of the fire.
“But the home owners wanted to start cleaning up the property straightaway. We were advised that the house was not insured. If the house is insured then the property owner has no right over the remains but if it’s not insured, they can do whatever they want.”
