Firefighters are urging caregivers to keep cigarette lighters well out of reach of children after a blaze destroyed one Whangārei home and damaged another.
The alarm was raised just after 5.30pm on Friday, and although the first fire truck arrived within four minutes, the two-storey home on William Jones Drive in Ōtangarei was gutted.
Fire investigator Gary Beer said a woman and two children were home at the time but managed to get out safely.
A firewall saved the adjoining home, but it sustained some damage due to fire spreading through the weatherboard cladding.
Damage was so extensive, Beer said he could not be certain of the cause.
