Freezing overnight temperatures, rain and snow will batter the South Island this week.

MetService says a system is rolling in from the south bringing with it a "good wet southerly" behind it on Wednesday through to Thursday.

The weather is expected to mainly affect Southland, Otago and Canterbury and comes after wet wintry wash-out lashed the South Island last week.

MetService says showers will drench much of the island as well as up to 30cm of snow falling to as low as 400m in the foot hills and high country areas of Otago and Canterbury.

The system is expected to clear up later in the week but will bring freezing overnight temperatures for much of the South Island.

  • Invercargill 0degC, -4degC
