A crash blocking a lane on Auckland's Northern Motorway and a breakdown in the Victoria Park Tunnel are causing delays for motorists amid balmy weather.
Both incidents have since been cleared from the motorways but motorists were advised to expect delays.
The crash on the northbound route of the Northern Motorway, cleared at 11.20am, was also causing delays for southbound traffic due to rubbernecking, the New Zealand Transport Agency said.
The crash was reported at 10.55am on the right lane of the motorway just after the northbound Constellation on-ramp. Traffic is currently blocked all the way back to Wairau Park.
It would be tough for anyone without air conditioning, as MetService predicted a high of 27C in the City of Sails.
