Auckland commuters travelling on the Northern and Western motorways may need to allow more time as traffic slows to a crawl.
The New Zealand Transport Agency said there was no specific incident causing the build-up, but that morning congestion seemed to be getting earlier over the past few weeks.
Traffic on Auckland Transport's live feed showed at 7:40 this morning severe congestion along the Northern starting from Oteha Valley road, with the average speed slowed down to a 4 km/hr to 20 km/hr crawl up till Northcote Road.
Along the Western motorway it was a similar story with traffic building up from around Hobsonville with the estimated travel time into the city of 48 minutes.
Along the Southern motorway there was also some build-up around Mt Wellington.
