"It looked pretty intense but there was no damage to my house," he said.
A neighbour, who did not want to named, said the house was occupied by a man, the homeowner, and a woman who was a flatmate.
"I had the stereo going so didn't hear anything until my dog started going off. The house was already well alight by the time I looked out," she said.
The woman occupant stayed the night at her place.
Although tired and visibly upset, the woman spoke briefly to Horowhenua Chronicle to confirm she had managed to get her german shepherd Nikita out of the house safely and over the fence with the help of neighbours.
She said her two cats were still missing and her pet bird died as an indirect result of the fire. "You can't believe how much heat is generated. I got my bird out first but I can't have put it far enough away from the house and the heat killed it," she said.
The dog belonging to the male occupant was also missing.
Mr Walker said the fire was being treated as suspicious and he could not confirm if there had been working smoke alarms in the house.
He said fires spread quickly and it was important to have working smoke alarms to give occupants valuable time to get out.
Detective Sergeant Dave Wilson from Levin Police confirmed, at time of going to print, that the cause of the fire was still unknown and the investigation continuing.
