KEY POINTS:
The fire that destroyed a Department of Conservation ranger's cottage on Kapiti Island was caused by ashes removed from a log burner.
DoC Kapiti area manager Ian Cooksley said the ranger had gone out for a few minutes and returned to find the building ablaze.
Each year on average, 82 house fires are caused by the incorrect disposal of hot ashes, said Fire Service investigation officer Russell Postlewaight.
"It's critical that ashes are placed in a metal container well clear of the home and, for increased safety, water is poured over them."
