More rain is forecast for Auckland and an already drenched Northland on the year's shortest day, as a slow-moving low gradually moves north.
MetService meteorologist Karl Loots said a heavy rain warning north of Whangaparaoa had eased but rain would persist in Auckland until the afternoon, and in Northland until this evening.
In the past 24 hours, parts of Northland recorded over 150mm of rain.
Puhipuhi north of Whangārei got 166mm, and a station in Whangārei town recorded 146mm.
Across the rest of the country cool temperatures but relatively fine weather was forecast, thanks to a ridge of high pressure.
A ridge sets up over the country over the next couple of days, clearing up the weather! This will mean some frosty starts and unfortunately there could still be cloud around! Check your forecast at our website https://t.co/Yjbq0jfCz1

By tomorrow the ridge would have spread over the upper North Island, bringing a fine end to the week.
On Saturday a weak front was forecast to make landfall in the lower South Island, before a stronger front arrived overnight.
Rainfall was forecast for the South Island's West Coast on Sunday, spreading up the North Island's west coast by the afternoon.
Temperatures would drop on Saturday morning before the fronts move across the country.
Tonight at 10.07pm is the Southern Hemisphere winter solstice, marking the day with the shortest period of daylight and longest night of the year, when the sun's daily maximum elevation in the sky is at its lowest.
