Meanwhile, a 54-year-old woman died after a car left the road and rolled near Wanaka tonight.
Police said the grey Ford Falcon crashed about 3km south Luggate, east of Wanaka, about 6pm.
The woman, a passenger, died at the scene.
Police said the driver, a 62-year-old man, was flown to Dunedin Hospital with serious injuries.
The police serious crash unit was investigating.
The crash came only hours after a woman was seriously injured in a three-car collision near Milford Sound this afternoon.
Police said a Toyota Prado with five occupants crossed the centre line on a moderate bend about 10km from Milford as it was driving towards Te Anau.
The car collided with a sedan travelling towards Milford, injuring its two occupants, who were both 24-year-old women.
One suffered minor injuries while the other was flown to Southland Hospital with serious injuries.
The Toyota then hit another vehicle, but none of its six occupants were injured.
Police said the Toyota's driver, a 49-year-old man, would be charged with careless use of a motor vehicle causing injury.
Rain, speed and inattention were all believed to be causes in the crash, police said
