Crews fought a house fire near Tauranga for more than three hours overnight.

A Fire and Emergency New Zealand spokesman said it received multiple calls about a fire at an Ōmanawa property just after 9pm yesterday.

“On arrival, crews found a house fully involved.

The spokesman said the fire measured 20m by 10m.

He said crews extinguished the fire and dampened down hotspots before leaving soon after midnight.

There were no reports of injuries and a fire investigator will be attending this morning.

Three fire trucks and three water tankers went to the scene.

The fire was not being treated as suspicious.
