A 50-year-old man has died after the motorcycle he was riding collided with a car near the Onehunga off-ramp of Auckland's south-western motorway this morning.
He had been transported to Auckland Hospital in a critical condition, St John Ambulance spokesman Robbie Walker said.
Police and St John attended the crash on Onehunga Harbour Road just before 7am.
The incident closed the on-ramp and off ramp to south-western motorway at Onehunga, backing up west-bound traffic for kilometres.
Both the on-ramp and the off-ramp have since been re-opened.
