One person is in critical condition following a crash on the South-Western Motorway near Māngere overnight.

The two-vehicle crash, involving a car and a truck, was reported at 4am on northbound lanes by the Coronation Road off-ramp.

The car driver of the car had to be extracted from the vehicle and was taken to Auckland City Hospital in a critical condition.

Two northbound lanes of the motorway were closed alongwith the off-ramp while the Serious Crash Unit conducted a scene examination.

The New Zealand Transport Agency said on X traffic was heavy as far back as the link from State Highway 1.

However, in an update at 8.30am it said all lanes and the Coronation Rd off-ramp had now re-opened.
