Canterbury motorists are being warned to watch out for slips and washouts on a number of roads across the region.
Graeme Hall from Waka Kotahi NZ Transport Agency said the slips and rockfalls will continue throughout the week.
"We encourage everyone to check our traffic map before heading off so they know which routes are closed or will take longer."
Lindis Pass, State Highway 8, between Omarama and Tarras, is the route most affected by slips.
There are multiple slips on Lindis Pass and a bridge abutment needs a full inspection, said Hall. The pass will remain closed overnight.
