A villa set to be moved from Hastings to Waiheke Island was gutted early yesterday morning and is being treated as suspicious.
The Fire Service were called to the unoccupied home on the corner of Nottingley Rd and Lyndhurst Rd in Frimley at about 2am on Monday.
Hastings Fire Station officer Michael Manning said crews from Napier and Hastings were there within three minutes and found the house "well involved" from the back.
"We launched an aggressive attack and cut the fire off but the structure of the building was about 25 per cent damaged."
"Most of the old villa was native timber, which fuelled the fire. We got in under control and left the scene by about 6am yesterday morning," Mr Manning said.
