One impatient motorist had her licence immediately suspended when police clocked her passing a line of slow-moving traffic at 150km/h yesterday.
The Queenstown woman, whose two children were in her car, was stopped on State Highway 1 between Dunedin and Milto, about 7pm.
Police said when stopped, the 28-year-old woman admitted speeding, saying she was sick of waiting in line as the other cars were driving too slow.
She received a 28 day licence suspension, 50 demerit points, and infringement notices for the excessive speed, driving on an expired licence and in an unlicensed car.
There was heavy traffic congestion on highways across the country today.
Motorists on Auckland's Northern and Southern motorways were warned of major delays due to the heavy traffic, the New Zealand Transport Agency (NZTA) said.
Southbound traffic on the Southern Motorway was backed up between the Manukau interchange and the Bombays, Hampton Downs to Rangiriri, and Ohinewai through to Huntly earlier today.
On the Northern Motorway, there was heavy congestion between Orewa to Johnstones's Hill Tunnel and Wellsford, NZTA said.
The heavy traffic comes as a transport expert's study found traffic delays could be made worse when drivers ignored warnings about congestion.
University of Canterbury transport engineer Professor Alan Nicholson said drivers did not divert to alternative routes unless they could see the queue, even if they had already been warned of a blockage.
There have been no fatal crashes this Easter as of 6pm today.
