Wet weather is causing commotion on Auckland roads this morning with crashes littering the motorways.

A crash on the Northwestern Motorway, State Highway 16, is blocking the right lane citybound under the St Lukes Rd over bridge.

Motorists are advised to merge left to pass and expect some delays back to Te Atatu

There was also a crash on the Upper Harbour Highway, just before the Greenhithe Rd off ramp, which is now cleared but still causing delays back to Squadron Dr.
