A scrub fire north of Kaitaia is believed to have been started by a preschool child playing with matches.
Northern principal rural fire officer Myles Taylor said about a hectare of scrub at Motutangi, south of Pukenui, burned on Friday afternoon before ground crews and helicopters got the blaze under control.
A ground crew was still there yesterday checking for hotspots.
Kaitaia's chief fire officer, Colin Kitchen, said the property owner was lucky to still have a house.
The brigade had dispatched one appliance and a water tanker, along with two appliances from Houhora, tankers from Mangonui and Karikari, and two helicopters.
