A house fire in a Lake Taupo community was likely caused by a leaking fish smoker, investigations have found.
Turangi Volunteer Fire Brigade Chief fire officer Tangonui Kingi said a Kuratau home was "fully involved" in flames by the time they arrived yesterday.
The fire started about 7.55am and was attended by crews from Turangi, Taupo and Manunui, near Taumarunui, Mr Kingi said.
"North comms [communications] received multiple 111 calls, which generally indicates that something is definitely going on," Mr Kingi said.
He said Turangi Fire Brigade responded with two crews and a support vehicle but before they left they upgraded the call out to "second alarm" which meant a crew from Taupo also set out.
