Six people have been taken to hospital after a fight in west Auckland that witnesses say culminated in a car driving into another vehicle and a group of people.
Emergency services were called to the incident on Clayburn Rd in Glen Eden just after 12am on Sunday morning.
One person suffered serious injuries, and the other five are in a moderate condition.

Caleb Simpkins, a resident at a house near the party the incident is alleged to have happened at, said the incident started with verbal abuse before escalating rapidly.
"I just heard a party and some singing, and after a while [there was] just heaps of swearing and heaps of noise," he told Newshub.
"I thought it would calm down, but after about two or three minutes the fighting kept going, so I thought I'd better have a look."
Mr Simpkins said that when he came out of his house, he saw a group of people fighting near the end of his driveway. He said the incident was scary to see, and described the mob-like brawl as being too difficult to intervene in.
But it was about to get worse moments later.
"I heard the car crash, smash into another car and people - and everyone just started running," he recounted.
"As soon as I heard the car crash, I knew people were hurt just by the different sounds of screaming that I heard."
After witnessing the crash, Mr Simpkins said he then ran back to his house and rang emergency services.
