Traffic is flowing on Auckland's Northwestern Motorway after a crash earlier today caused delays.

A vehicle rolled just after 7am, blocking the westbound on-ramp to Lincoln Rd in the city's west.

Emergency services were called to the scene and cleared the site just after 7.30am.

St John confirmed they were called out to the scene and attended to one person. However, they were uninjured and did not require hospital treatment.


The NZ Transport Agency issued a warning to motorists in the area to expect delays.

It later said the crash had been cleared, but warned motorists to take extra care in the area and expect some delays.
