A dominant and very powerful high pressure system is continuing to impact NZ and will do so for another week.

An easterly flow continues in the north, on the edge of the high (as the high is centred further south) and this will see a few showers here and there in the eastern and very upper North Island.

WeatherWatch.co.nz head forecaster Philip Duncan says all of NZ will be much drier than average for this time of year. “This high pressure belt is extraordinary large, meaning it will take at least a couple of weeks to move through. Modelling we trust most suggests the high will be leaving NZ later next week which then potentially opens up a brief window for rain or showers, before the next big high rolls in”.
