Blake Lyon moved from Auckland to Whangarei for a quieter life.
But he's been left thanking his lucky stars after a woman got into his empty, idling vehicle and drove erratically around Onerahi for several minutes.
Mr Lyon says he dislocated his shoulder diving out of the way of his vehicle while the stranger was at the wheel.
He had stopped to investigate what looked like a car crash about 9am on Saturday at Church St, Onerahi. He left his vehicle's engine running and his dog inside. However, a woman got in his car, and drove off, taking the dog with her.
At one point, the vehicle slammed into a power transformer Mr Lyon had taken cover behind, and he fell to the ground.
