Heavy rain has hit the Buller area with surface flooding and a debris flow at Lamplough Stream, NZ Transport Agency contractors report.
State Highway 67 has been closed from Hector to Little Wanganui/ Lamplough and a manned road block is in place until 10 pm tonight when it will be reassessed, said NZ Transport Agency Journey Manager Lee Wright.
"There are minor slips up the Coast Road and some surface flooding in the Lower Buller Gorge, so we urge road users to take care and delay heading north of Westport or Hector tonight."
The rain has eased, at least for the time being, in South Westland, she said.
