State Highway 2 in central Hawke's Bay has reopened after a truck left the road killing two people early this morning.
Police confirmed a 40-year-old man and his 7-year-old son died when a truck left SH2.
A Greaves Bulk Haulage truck and trailer left the road and plummeted down a cliff 5 kilometres north of Norsewood about 12.30am.
The accident site, on the hill just north of the Manawatu River bridge, was congested this morning as tow trucks and an arborist worked to prepare the area for a crane to lift the truck and trailer from the crash site.
The truck was being contracted by Gisborne transport company, Weatherall Transport.
