A motorcyclist has been killed in an accident on Auckland's Dominion Road, an hour after a multi-car smash in the same area.



The motorcyclist's body remained on the road, covered in a shroud, as police dealt with the scene.



Dominion Road is one of Auckland's busiest suburban streets and both dramas took place in the area around the intersection with Valley Road.



An eyewitness, who was the first person on the scene, said the second crash was "horrendous".



He said it appeared the motorcycle was speeding when it crashed into a car.



"He had a passenger. I got to the passenger first and she was in quite a bad way. They've carted her off to hospital," he said.



The eyewitness said the driver of the motorcycle was dead, while police said the female passenger was in a "serious condition".



The driver of the car appeared to be physically unharmed, but in "major shock".

EARLIER PILE-UP

A man faces a charge of driving while incapable after crashing into several parked vehicles on Dominion Road this morning.



He is alleged to have hit four parked vehicles during a late morning incident near the intersection of Dominion Rd and Valley Rd.



The man was assessed by ambulance staff, but did not want further medical treatment, police spokeswoman Noreen Hegarty said.



Two other people were taken to hospital for observation.



Police were alerted at 10.52am and were told by witnesses that a car was driven in an "erratic and dangerous manner" before hitting other vehicles.



The driver was taken into custody by members of the Armed Offenders Squad, who happened to be in the area as part of a drug operation targeting the Hells Angels' gang headquarters in a nearby street.



Ralph Ingram, manager of the Videon video store on Dominion Road, was walking to a bank when the incident happened and he said it was fortunate that the consequences were not more severe.



"There were tons of people around," he said. "Luckily no one died."



Ingram said he heard the sounds of a car braking and then something smashing.



"When I looked up, I saw a maroon car come screaming across the road and hit a white pick-up and bounce off," he said.



"There was more noise and then he smashed into a black Integra."



When the car came to a stop, passers-by went to check on the driver, who came out clutching a rugby ball and looked around, before shock appeared to set in and he sat down and started to cry.

Motorists were advised to avoid the city end of Dominion Rd as it is blocked between View and Bellevue Roads.
