Fire that destroyed a former paua processing plant in Napier is being treated as arson.
State Highway 2 at Awatoto was closed for most of Sunday after fire destroyed the unoccupied seaside building, which contained paua farming equipment from Paua Fresh which closed about three years ago.
Police say the building was set alight about 2am on Sunday.
Close neighbour Shayne Govsky said he was threatened with arrest if he did not evacuate his home "which all but went up". The fire almost spread to his roof before hoses were trained on it.
"I ended up being in my car on the side of the road until about 8.30am, when they let me back into my house," he said.
