A crash during rush hour in Wellington has caused a back up in traffic around the Terrace Tunnel.

Motorists heading home this evening may want to detour to avoid getting caught in queues.

New Zealand Transport Agency Wellington tweeted about half an hour ago, warning people about the crash, which is blocking the left-hand lane for drivers heading north out of the tunnel.

"It's so chocka that there was hardly room for people move out of the way for emergency services," she tweeted.
