Auckland's northern motorway was blocked after a digger scoop came off the back of a truck after a crash on Monday morning.

All lanes had been reopened by 10am, but motorists could continue to expect delays as congestion eased in the area, NZTA said. 

 

It had been blocking all city-bound lanes between Greville and Oteha Valley Roads.

Motorists have been warned to avoid the area.
