A South Auckland man switched on his electric blanket and within minutes his home was ablaze.
The man was at his Wattle Downs home in South Auckland at about 8.30pm on Sunday when he noticed a haze in the air.
He checked behind his TV and then inspected the kitchen before walking into the bedroom to find his bed in flames.
Fire and Emergency Manurewa station officer Mike Carter said the resident quickly dashed to his garage for his fire extinguisher, but when he returned the entire bedroom was engulfed in flames.
"By the time he raced to the garage to fetch his fire extinguisher, all the windows and glass were flying out of his bedroom. So it went pretty fast."
