Chances are slim another polar blast will hit the South in the next few weeks, but the possibility of a snow storm in spring still exists, a climate scientist says.
New Zealand has been battered by two snow storms in the past month, with the second bringing many parts of the country to a halt for a day or two.
National Institute of Water and Atmospheric chief climate scientist Dr James Renwick said the circular atmosphere in the southern hemisphere had brought more storms across New Zealand than normal.
Westerly winds had also "waxed and waned" on a monthly basis, and when strong they brought storms over the South Island.
The weather pattern had stuck around for a few months and would possibly linger until the end of August, Dr Renwick said.
"The other complication is that they are not terrifically predictable."
However, the forecast for the next week or so did not show any change in weather patterns.
A two-week forecast for New Zealand from the United States showed the weather pattern persisting over the next week before easing off.
"The chances of us getting another extreme storm another week down the track is pretty slim."
Niwa's seasonal outlook did not predict any "especially disturbed conditions" for September and October. However, the country could experience the more typical frontal systems for the time of year and spring storms were a possibility, he said.
