CauseOn the 4th, a strong disturbed north-westerly flow spread over New Zealand ahead of a deep trough moving in from the Tasman Sea, with several fronts. A low had formed west of Fiordland by the end of the day, bringing cold air to the far south. On the 5th and 6th, the system moved away to the south-east, and a strong westerly flow covered the North Island. Cold fronts brought cold south-westerlies to the South Island and cold air moving onto the North Island brought snow to the central high country there. On the 7th, a weak anticyclone moved into the south Tasman Sea, changing the flow over New Zealand to a lighter southerly, although it was still very cold.

DurationFrom the night of the 4th till the 7th November.
