Water levels in South Canterbury's flooded rivers are receding, but motorists are being warned that surface flooding on roads will take some time to drain away.
A spokesperson for Canterbury's regional council says 150mm of rain has fallen in the South Canterbury foothills in the 36 hours to Saturday evening, and the region's rivers and streams have experienced moderate flooding.
There is surface flooding in 10 places on State Highway 1 between Timaru and Glenavy, and on State Highway 82 between Waimate and Kurow.
The council says the rain is easing and water levels are dropping, but motorists should take extreme care, particularly after dark.
Meanwhile, the road near Bluff where a woman was killed on Saturday afternoon has been re-opened.
The woman died at the scene when a car and a truck collided on State Highway 1 at the intersection with Greenpoint Road.
