Unfortunately for the property owner, he had placed his tree directly under a man-hole in the ceiling, which exacerbated the fire very quickly.
Mr Kennedy said the heat and force of the fire acted "like a chimney", quickly funnelling the fire directly into the ceiling space.
When the resident went to investigate why he had lost electricity suddenly, he was met by a neighbour running across the road shouting "your house is on fire".
Three fire appliances, including one from Waimangaroa, were needed to control the blaze and firefighters were at the scene for two hours.
The house suffered severe smoke and water damage, with the fire in the roof causing ceilings to collapse. The owner had lost all his possessions.
"I don't think it will be a rebuild. The whole roof had collapsed," Mr Kennedy said.
"The outcome is: renew your Christmas lights."
He said people should be buying light sets which had an in-built voltage reducer from 240 volts down to 12 volts and "don't leave them on all day and all night".
