Eight people are injured, including three critically, after a fleeing driver smashed into another car in Fendalton, Christchurch.
Canterbury police metro area commander Superintendent Lane Todd said a vehicle failed to stop for police on Papanui Rd about 4am on Tuesday.
The vehicle was signalled to stop due to the manner of driving.
A chase began which lasted for about four minutes through residential streets, before the car collided with another vehicle driven by a member of the public at the intersection of Glandovey Rd and Idris Rd in Fendalton.
St John spokesman Gerard Campbell said eight people were injured – three critically, two seriously and three moderately. All were taken to Christchurch Hospital.
Five ambulances and two first response vehicles rushed to the scene.
Todd said the Serious Crash Unit is examining the scene and the Independent Police Conduct Authority will be notified.
The intersection of Glandovey Rd and Idris Rd would be closed for a number of hours with diversions in place, he said.
One person was trapped and rescued from the vehicle by firefighters, Fire and Emergency New Zealand spokesman Simon Lyford said.
A Christchurch Transport Operations Centre statement said motorists were advised to use an alternative route and should expect delays.
Glandovey Rd was closed eastbound at Garreg Rd and westbound at Heaton Rd, Rossall St and the Strowan Rd intersection.
Idris Rd was closed northbound at Wroxton Tce and southbound at Plynlimon Rd.
