MetService meteorologist Lisa Murray, just south of the Banks Peninsula, said there was a slow-moving decline in the eastern part of the country. "Around a clock counterclockwise, that is, the flow towards the land to the lower half of the South Island is either southeast or south. That's why it feels so cold out there."

He said that this week's snow, wind and rain merged with a high south of the South Island, and slow-moving westward to slow motion.

"With high seating on that day, it is bringing southeastern winds in Otago and Canterbury, bringing wet weather and snowing at high altitudes."

Flynn said the high level continues to move away from the east as fast as usual.
