A spokesman said Tuesday afternoon’s showers would develop in the evening, with snow lowering to 700 metres and southwesterlies becoming strong in exposed places.
From midnight onwards, there would be scattered showers and snow would possibly lower to 500 metres, he said.
The risk of snow amounts reaching warning criteria anywhere was minimal at this stage, but some higher roads and farms may be affected.
Snow showers have been forecast for alpine roads over the next day as well as the Crown Range, linking Queenstown and Wanaka. From 2pm to 6pm on Tuesday, 2cm of snow may settle near the summit of the road, with lesser amounts to 800 metres.
The Milford Road (State Highway 94) is open.
In the North Island, heavy snow is expected to fall on the Desert Road (SH1) and around Taihape from Wednesday.
Meanwhile, drivers are warned to take extreme care on icy roads. A spokeswoman for the Central Otago District Council said Alexandra was "especially bad" this morning.
Auripo Rd is restricted to 4WD due to flooding.
In the Queenstown Lakes area, there's lots of ice and grit about and road users should take care particularly over the Crown Range, through the Cardrona Valley and the Kawarau Gorge.
Many of the roads in the district were wet again and temperatures low, meaning a high chance of ice/black ice.
The Queenstown Lakes District Council tweeted mid-morning that black ice was forming on Malaghans Rd. It's pretty frosty in Wanaka also, with road warnings in place.
Remember to drive to the winter conditions and reduce speeds accordingly.
