Traffic is now flowing in both directions at the scene of a crash on State Highway 6 between Lumsden and Dipton this morning that spilled palm kernel across the road.
The highway was reduced to one lane for about five hours after a trailer containing the product overturned about 11.15am near the intersection with Caroline Valley Rd.
Police said the driver of the truck towing the trailer was not hurt in the incident.
Meanwhile, bad weather and the threat of rockfalls has forced the closure of State Highway 1 between Peketa and Goose Bay, south of Kaikoura, the New Zealand Herald reported.
It was expected to be closed until tomorrow.
Motorists travelling to Kaikoura in the meantime have been advised to use Inland Route 70 between Culverden and Kaikoura.
