A Hastings house, mid-way through the removal process, was destroyed by fire in the early hours of Sunday.
Police are investigating the suspicious fire that drew Hastings fire crews to the Heretaunga Club carpark at 12.38am.
They found a house close to the Hastings St footpath on fire and were forced to disassemble a protective fence to gain access.
It was one of three houses stored on the site as part of the club's nearby development.
Hawke's Bay Senior Sergeant Dan Foley said the blaze was being treated as arson.
