Three lanes of a major Auckland motorway have been blocked by a crash, causing significant traffic delays.
Earlier, only one westbound lane was passable after the crash on the Northwestern Motorway, which happened around 7pm. One lane has since reopened.
A police spokesperson said the crash has left one person seriously injured.
The blockage is between the Great North and Rosebank Rd exits on the westbound side.
Waka Kotahi is warning motorists to find another way home tonight and to be prepared to face major delays.
