Traffic has eased on Auckland's northern motorway after two crashes caused gridlock this morning.

NZTA spokeswoman Sarah Azam said it appeared traffic was moving again after a serious crash blocking all lanes near Greville Road was cleared by emergency services.

The crash citybound on the Northern Motorway at the Greville off-ramp was earlier blocking all lanes.

An earlier crash near Northcote had also blocked a lane and left traffic backed up to Greville Road.


Those who wanted to head to the city were asked to use an alternative route via East Coast Road.
