A two-vehicle crash has been cleared from the centre of Auckland's Harbour Bridge.

The crash was blocking centre lanes 3 and 4, heading north before the rise of the bridge.

The NZ Transport Agency said there were still delays approaching the bridge and motorists should allow extra time if possible.

A police spokeswoman said police were called at 2.39pm to the crash, where one car had rear-ended another. The crash was minor with no reported injuries, she said.
