A faulty multi-plug box has been identified as the likely cause of a fire that destroyed a shed, a boat and a car at Ōhaeawai.
Ōkaihau Fire Brigade station officer Ben Scott said the roughly 7m by 7m shed was completely destroyed in the blaze, along with a trailer boat stored inside and a nearby car.
Kaikohe and Kerikeri brigades also responded to the fire at a State Highway 1 property about 12.45pm on Saturday.
Fire investigator Craig Bain said the likely cause was a fault in a multi-plug box.
He advised Northlanders using inexpensive multi-plug boxes, also called powerboards, to replace them every five years.
