Three fire engines, several police cars and an ambulance attended the crash at Greenhills, on the outskirts of Bluff, about 12.30pm.
A police spokesperson said initial indications were that one person received critical injuries in the crash and the serious crash unit was advised.
In an update just before 7pm yesterday police confirmed the sole occupant had died and an investigation into the crash was underway.
It appeared the vehicle had left the road and ended up in bushes.
A Fire and Emergency New Zealand spokesman said when crews arrived the car was on fire.
Traffic was backed up for a time leading up to the crash scene.
The police update last night said the road remained closed while a scene examination was taking place.
A Hato Hone St John spokeswoman yesterday said it responded with one ambulance, one rapid response unit and one manager.
