MetService has tonight issued some road snow warnings for the South, overnight and into tomorrow.
The forecaster said a couple of weather systems moving across the country could bring a brief period of snow to elevated parts of the South Island early on Wednesday.
The same systems were expected to bring strong winds, rain, and thunderstorms to parts of the North Island.
MetService has road snow warnings in place for the Lindis Pass (State Highway 8), the Crown Range Road, and the Milford Road (SH94).
NZ Transport Agency Waka Kotahi says chains must be carried on the Milford Road between Hollyford Rd Junction and Donner River bridge.
There are also strong wind watches in place for coastal parts of Dunedin and Clutha from Otago Peninsula southwards from 7am to 4pm tomorrow, and for Stewart Island and coastal parts of Southland from 4am to noon.
