Major delays on Auckland’s SH20 after multi-vehicle crash

There are major delays on South Auckland’s State Highway 20 this afternoon after a multiple-vehicle crash.

Police were called to the scene near the Massey Rd on-ramp near Māngere at 3.20pm.

The three-vehicle crash had blocked all but one lane on the motorway, the spokesperson said.

The lanes are now open, however, motorists are still being told to expect residual delays.

Video from the scene shows a large truck has rolled and blocked lanes.
