A "dominant and very powerful" high-pressure system is impacting New Zealand and will continue to do so for another week.
"This high-pressure belt is extraordinary large, meaning it will take at least a couple of weeks to move through," WeatherWatch.co.nz head forecaster Philip Duncan says.
"Modelling we trust most suggests the high will be leaving New Zealand later next week which then potentially opens up a brief window for rain or showers, before the next big high rolls in."
NIWA too is forecasting a rainmaker to cross the country between the 26-28 March - next weekend.
"As we head into April, a pulse of the Madden-Julian Oscillation (i.e. climate forcing) will enter the Australasia region, leading to an increase in the chance for low pressure and rain around New Zealand," it says on Facebook.
"After a dry summer, April *could* turn out to be one of the wetter months in a while."
