People in Central Otago and Northern Southland are being warned to brace themselves for another cold snap.
Snow had already been forecast for parts of the region on Wednesday, but MetService was now predicting another period of snow on Friday which may fall to lower levels than earlier in the week.
A MetService spokesman said there was still low confidence that a snow warning would be needed for Central Otago on Wednesday, but the chance of significant snow below 600m had reduced.
However, there was a possibility warning amounts of snow would fall above 400m on Friday in Northern Southland, Central Otago, Canterbury, Marlborough and Nelson.
"Gale southerlies associated with the lows are likely to affect eastern areas of the South Island and southern North Island late on Thursday and during Friday,'' he said.
