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.
Otago Regional Council is also urging people to be cautious around rivers and low-lying areas.
Rivers and streams in Central Otago and the upper Clutha continue to rise and are expected to remain high today.
Aoraki/ Mt Cook, SH80: Closed between Ben Ohau and Aoraki/ Mt Cook due to a slip this morning.
Omarama to Kurow, SH83: Flooding closed this route at 7am.
SH77 Methven to the Rakaia Gorge between Holmes and Mt Hutt Station Rds:
- A washout on this route means it is controlled by Stop/Go currently.
- An earlier washout between Blackford Rd and Mt Hutt Station Rd on SH77 is also active with narrow lanes and 30km/h.
Local road closure due to bridge washout, Lake Ohau Rd, near Twizel: This road/bridge closure is about 300 metres from SH8.
