The latest blast of wintery weather continues to cause hazardous conditions on many of New Zealand's roads.
Some Dunedin city schools were closed on Monday morning because of snow and ice on the roads.
Emergency services warned motorists in Otago and Southland to take care while for hundreds in Dunedin, just getting to work was a nightmare.
The Desert Road from Waiouru to Turangi in the central North Island was only reopened at 1100 Monday morning after heavy snow. However, Transit New Zealand was advising motorists to take extreme care.
Police were also urging extreme caution in many parts of the South Island, where ice and snow have caused treacherous driving conditions.
It was advised Alpine Passes were still subject to rapid change.
All highways in Otago were affected, the northern motorway from Waitati into Dunedin was closed, as were several main streets in the city.
State Highway 6 over Spooners Range, near Motueka was closed, with a detour suggested via Golden Downs.
Grit was laid throughout the main highways in Southland and motorists were urged to take care if travelling in the West Coast, Marlborough and Nelson regions.
The southerly front swept up the South Island in the early hours of Sunday, covering much of Southland, Otago and inland Canterbury in a white blanket from the coast to the mountains.
The east coast from South Otago to Banks Peninsula also caught the worst of it and intermittent light snow is still falling in Dunedin and Christchurch.
Skiers at Queenstown and Mount Hutt have welcomed the snow, while hill country farmers were expecting it and said it had not caused any problems.
