A woman is nursing an injured shoulder after a stolen car slammed into her vehicle, ending a police chase along the Southern Motorway and through South Auckland.

The chase began about 10.30am on Friday when the car sped off toward Auckland after being pulled over by an officer in Pokeno, 50km south of the city, a police statement says.

The car had been earlier spotted in Waikato's Te Kauwhata and identified as stolen.

Officers chased the car along the Southern Motorway before it turned off and drove through Manurewa with police following closely behind.

The car then allegedly rammed a stationary police vehicle which was blocking the road before hitting a nearby car, injuring the woman driver's shoulder.

A Manukau Counties Police spokeswoman wouldn't reveal to NZ Newswire what speeds the chase had got up to as the incident was being investigated by the Independent Police Complaints Commission.

The driver of the stolen car, a 36-year-old man from Mangere, is being held in custody charged with driving offences and other unrelated charges.

The man had 18 outstanding warrants for arrest against him.

A 32-year-old woman who police say was a passenger in the car is also being held in custody charged with association with a stolen vehicle.
