A helicopter has been deployed by Civil Defence to locate a group of motorists on the West Coast of the South Island.
The motorists are stuck in the middle of a road closure due to gale-force winds and falling trees.
Police and West Coast Civil Defence have responded to reports of several motorists struck on State Highway 6 between Franz Josef and Fox Glaciers.
The helicopter was being sent to find the exact location of the motorists and the number of cars stuck, West Coast Civil Defence spokesman Mark Crowe said.
Roading contractors from NZTA were working from either side of SH6 to clear the road and allow the motorists a way out, he said.
NZTA closed SH 6 from Ross to Makarora at 10.30am and it was expected to be closed until further notice.
The call adds to the woes of the West Coast which is being pelted by the power of ex-tropical cyclone Fehi.
