Ice is causing Dunedin motorists to slide off the roads and police are advising people to take extra care.
Acting Senior Sergeant Damion Rangitutia said two cars had left the road in the Saddle Hill area in the city's west. No-one was hurt.
Patrolling police had reported ice on the roads on State Highway 1 at Green Island, on Kaikorai Valley Rd and on Highgate.
Roading contractors were this morning laying grit on icy spots to avoid further accidents.
"It's very slippery out there so we really advise people to take extra care this morning," Mr Rangitutia said.
According to MetService it was 3.9 Celsius in Dunedin at 6.30am, but felt like 1 Celsius.
