Crash inside Auckland's Waterview Tunnel

Two cars have crashed in Auckland's Waterview Tunnel.

The bumper-to-bumper collision happened around 12.15pm in the right-hand lane of the northbound tunnel.

The Transport Agency said the crash was initially blocking the right lane but was now clear.

Only one car was damaged in the incident, a spokesman said.

"It was a very minor thing."

A Transport Agency spokesman earlier said this was the first crash that had occurred inside the tunnel since it opened in July last year.

But another spokesman later clarified there had been at least one other crash before this.

Speed restrictions were in place while emergency services helped to clear the scene.

The crash site was cleared shortly after and the Transport Agency said traffic was flowing as usual through the tunnel.
