The NZ Transport Agency says a crash on the Auckland Harbour Bridge is causing delays for northbound traffic.
Two of the three northbound lanes are currently blocked. The barrier machine is now operating to allow an extra lane to be opened northbound but this will take about half an hour.
Motorists are advised to allow extra time for their journeys, avoid the area if they can and use the Western Ring Route including the Northwestern and Southwestern motorways as an alternative.
