A powerful high pressure zone continues to track over New Zealand but starts to slip away to the east later today, allowing for a milder sub-tropical northerly flow to develop in many regions.

More isolated showers and the odd heavier downpour are possible in the western North Island and once frosts clear from the South Island a stunning day is on the way for many places.

As early as tonight a slight sub-tropical northerly breeze should build in the lower South Island (Fiordland firstly) with a milder Monday and Monday night coming for most places.

To drill down deeper, see the hourly forecasts going 10 days out at WeatherWatch.co.nz and our Free App – or see graphs and more data than any other weather site for New Zealand at www.RuralWeather.co.nz (app coming later this year).
