Traffic problems are again plaguing the arterial routes heading north from Auckland.
The New Zealand Transport Agency said, about 3pm, that SH 1 from Puhoi to Warkworth had "major congestion", and drivers could use SH 16 as a detour.
SH 1 approaching Wellsford was also congested, with the agency saying drivers should expect delays.
Traffic was free-flowing over the Harbour Bridge and through Albany.
Yesterday, crashes caused major delays on the Southern Motorway.
