Stock food spilled across a major Northland road after a 50-tonne truck and trailer unit rolled.
The crash south of Whangarei blocked southbound lanes on State Highway 1, near Smeaton Hill, about 1am yesterday.
Northland police spokeswoman Sarah Kennett said the driver lost control of the northbound truck on the northern side of the hill, just south of Whangarei, and it went into a ditch.
The vehicle had travelled for about 100 metres before spinning out and rolling and crossing the southbound passing lanes.
The truck was carrying palm kernel, which had spilled across the road.
