In an update around 8.40am, Waka Kotahi NZ Transport Agency said the road had reopened with stop/go traffic management in place near Te Toke Rd.
An NZME reporter at the scene said about 10 people were present wearing high-vis.
One lady stood with her arms folded with a look of shock and distress on her face as the crew searched through the pile of freight for anything which could be saved.
A stop/go one lane was in place.
Rubbish and damage to the truck could be seen from the roadside and the crew started to load salvageable items and large packages into the truck’s trailer.
