The Act candidate for Dunedin South at this year's election said he parked the Ford Laser outside the Waterloo Hotel, in Caversham, on Saturday about 7.40pm while he and his wife had a meal.
When he came out of the hotel about 9.40pm, the car was gone.
He was phoned on Sunday morning by police, who said they found the burnt-out shell of the car in Green Island Bush Rd and were investigating.
