The big high that gave NZ a stunning long weekend is now a blocking high to our east and is feeding in a warm subtropical nor'easter. By Friday and the weekend we are back to west to south west winds - with westerlies the theme for the next couple of weeks.
Strong winds and isolated downpours are expected across the country today.
Strong winds from the north-east are blowing across a number of regions today with gusts to gale-force around some exposed areas, Weather Watch head analyst Philip Duncan said.
He said the nor'easter could cause isolated power cuts, although windswere "well below damaging today".
Strong gusts are possible around the ranges in the south and coastal areas in the north, he said.
Winds will gradually ease throughout today and this evening as the large high continued to slowly track eastwards away from the country, he said.
