New Zealand is in for a spring blast for the first weekend of November and severe weather warnings may be issued.

WeatherWatch.co.nz says high pressure will remain to the north of the country this weekend while deep air pressure remains around the Southern Ocean, placing New Zealand directly in a severe squash zone of air pressure - in other words, a blast of strong winds are coming.

The west to north west winds will peak on Saturday PM nationwide and continue across the South Island and lower North Island on Sunday.

"Severe wind warnings may be issued by Government funded forecaster MetService. Rain warnings may also be issued for the West Coast and surrounds as heavy rain sets in for the weekend."

WeatherWatch.co.nz says the system will ease next week although westerlies look more dominant next week, bringing some more wet weather to the western side of the country but a warmer, drier, week for much of eastern New Zealand.

Wind map for 10pm Saturday night.
