The Crown Range road between Queenstown and Cardrona has reopened after being closed for about two hours this morning because of snowfall.
A Queenstown Lakes District Council online advisory said snow was still falling on the road, and motorists should carry chains.
There has been light snow falling on the ranges around the Wakatipu Basin since early this morning.
The temperature at Queenstown Airport at 9.30am was a brisk 2.9degC.
The NZ Transport Agency for a time warned of snow on State Highway 6 between Kingston and Lumsden, but in an update around midday it said the road had cleared.
The Milford Road - State Highway 94 - was closed overnight but reopened this morning.
MetService meteorologist Lewis Ferris said the snow came from a cold southerly outbreak that followed on the heels of a weather system that passed over the region during Easter weekend.
The combination of cold air and showers brought a dusting of snow to below 1000 metres in some places, including a "decent" snowfall overnight in Kingston (700m).
Two centimetres settled on the Crown Range summit (1070m) and at Homer Tunnel (945m), while the Lindis Pass (971m) also had a dusting.
The forecaster also has a Strong Wind Watch in place for coastal Otago south of Palmerston. It says southwest winds may approach severe gale in exposed places throughout Tuesday.
