Horrified residents say a man was trapped underneath a car for up to a minute while a rioting mob shook the vehicle and threatened the driver.
One woman, who was staying in a house nearby, said the scene was like something out of the movie Fight Club, with young, drunk, shirtless men punching each other and shouting in the street.
The man remains in a critical condition after being hit by the car during a street fight in Panmure in the early hours of this morning.
Another person was injured but has since been discharged, an Auckland City Hospital spokeswoman confirmed.
Neighbours of the residents who hosted a party which spun wildly out of control last night said they "just knew [a fight] was brewing" when they saw young drunk men running down the street with baseball bats in the early afternoon.
