An indoor cannabis growing operation is thought to have sparked a blaze which badly damaged a house in the tiny Far North town of Moerewa.
A woman living at the Otiria Rd address raised the alarm when she returned home from a shopping trip about 1.20pm yesterday to see smoke pouring from the upper floor of the two-storey home.
Firefighters from the Kawakawa Fire Brigade, backed up by a crew from Paihia, entered the house in breathing apparatus and located the fire in an upstairs bedroom.
Fire chief Wayne Martin said the blaze was quickly extinguished but the house was badly smoke damaged. No one was inside at the time, though people were in a sleepout on the same property.
It was only when the smoke cleared that it became evident the room where the fire started was being used to grow cannabis.
