People are being encouraged to maintain their smoke alarms after one Rotorua family was lucky to escape from its burning home.
Fire crews spent up to three hours attending a blaze on Aquarius Dr in Kawaha Point just before 2am on Tuesday.
Rotorua fire safety investigator Stuart Booten said he believed the fire started from an electrical fault in the kitchen.
He said the occupants, three adults and an infant, were taken to Rotorua Hospital to be treated for smoke inhalation and were later discharged.
"There was a smoke alarm but unfortunately the batteries had ran flat and had not been replaced," Mr Booten said.
