Unattended cooking and wind-blown sparks from controlled fires have ignited several blazes in Wairarapa in the past few days.
Masterton fire station officer Mike Cornford said the risks involved in both scenarios had played out in the town this week since a man in Vogel Cres left a cooking pan of hot oil unattended about 12pm on Sunday.
The pan burst into flame and set fire to a wall and the kitchen ceiling, causing extensive fire and smoke damage, and smoke sensors in the house were useless as the batteries were flat.
"There were children home at the time and it was a perfect example of why people should never leave cooking unattended and why smoke alarms should be fitted and functioning."
He said a fire also had erupted over a 150sq m area under gum and pine trees at a Miki Miki property on Monday, lit by sparks drifting from an earlier rubbish fire that had re-ignited after being put out.
