Motorists on Auckland's motorway network are being warned to expect delays after a crash near Drury this afternoon.
Southbound lanes were closed just north of the Drury off-ramp after a ute and a 2-axle trailer flipped at 3.30pm.
The sole occupant in the ute was not injured.
One lane now remains closed between Drury and Papakura.
A police spokesman said the scene was difficult to clear because of the large amount of timber on the trailer.
