A fire at a Mangakino holiday home appears to have been deliberately started, Tokoroa police say.
Emergency services were called to a Kauri Street address about 3.30am yesterday.
Detective Rick Rudolph said a neighbour discovered the fire after smelling smoke, hearing noises and deciding to investigate.
"After initial investigation by Fire Service and Police, it appears a fire was lit in a bedroom at the address. The house is a holiday bach and it was vacant at the time."
Detective Rudolph said the bedroom where the fire was lit suffered extensive damage, while there is moderate damage to the rest of the house.
