Motorists heading for Auckland's North Shore faced major delays this morning after a crash on the harbour bridge.
The NZ Transport Agency said at 9.45am that crashed vehicles were blocking the bridge's north-bound lane two, causing heavy congestion.
Motorway traffic was building up as far south as Khyber Pass Road.
The agency said motorists should delay any shore-bound travel if possible, or else use public transport or State Highway 16/SH18.
New Zealand Transport Agency spokesman Ewart Barnsley said the crash on the Harbour Bridge was a nose-to-tail, involving two vehicles.
Shortly before 10am traffic was backed up to Newmarket due to the crash. There was also some queuing on the western motorway.
Police said the crash happened shortly after 9am.
The drivers were able to get out of their cars after the crash but one person suffered minor neck injures, possibly whiplash, police said.
