A serious crash has closed a main road in the East Auckland suburb of Pakuranga Heights.
One witness claims he saw a car on the wrong side of the road collide with several other motorists.
Police were told of the crash at 4.01pm and say "initial indicators" are one person is injured.
It is understood the driver of one of the cars fled the scene and the police Eagle helicopter has been seen circling above Pakuranga Heights.
A witness said he believed the car driving on the wrong side of the road was doing more than 100km/h in the wide residential street when it collided with two other cars.
Photos of the crash show debris strewn across Pakuranga Rd and one car in the centre of the street with the entire rear smashed in and the front bumper missing.
A crowd of residents can be seen looking on as three fire engines, two ambulances and numerous police cars attend to the crash scene.
A huge line of traffic is also piling up along Pakuranga Rd, which police have cordoned off in both directions.
Motorists are being asked to avoid the area as the road is blocked.
