A breakdown has also now been cleared on the Northern Motorway after earlier blocking the left lane just after Oteha Valley Rd.
A crash on the Southern Motorway that had blocked the right lane just after Market Rd has also now been cleared.
Citybound traffic on the Northwestern Motorway was also delayed after a crash earlier blocked the motorway's right lane just after the St Lukes on ramp.
NZTA said traffic was heavy between Hobsonville and Royal Rds as a result.
Elsewhere, four people have been taken to hospital after an early morning crash east of Auckland, near Beachlands.
The two car crash took place on the Whitford-Maraetai Rd, just after Okaoro Dr at about 5.15am, a police spokeswoman said.
The crash initially blocked the road as the four people were taken to Middlemore Hospital for a range of minor to moderate injuries and the damaged cars were towed from the scene.
By 6.30am, Auckland Council had been called with a request to clean up oil from the road, but traffic was able to pass through on one lane.
