The road up to Arnott Heights in Greymouth, where slips have left 50 homes isolated, is still closed to traffic.
Geotechnical engineers had been working over the past few days to stabilise a "precarious" area of the Arnott Heights hillside.
A major slip that came down about midnight on Monday left the area cut off to residents and motorists.
There was further movement overnight on the shaky slope, resulting in some small slips.
A Grey District Council spokesperson said teams were hoping to put concrete blocks in place to provide a safe passage for traffic.
Residents with four-wheel drives were being allowed go up and down the hill.
Transport was being provided for people without a suitable vehicle.
