"As the high rolls in a cooler southerly flow is spreading up the nation.
"Rain is continuing around some parts of the North Island but the cooler southerly change is now moving in and this is helping ease rain in many places."
Heavy rain over Monday and early today in Auckland subsided in the afternoon, taken over with warm and humid conditions.
Tomorrow
Auckland, which is scheduled for its final day of alert level 3, should see its first fine day of the week with a high of 25C.
Meanwhile watches and warnings for heavy rain and strong winds remain in place for eastern parts of the North Island to this evening.
WeatherWatch NZ reports the rain this week as being "a positive outcome" for some areas heading into drought.
For some, well over a month's worth of rain had fallen.
One rain gauge between Waihi and Whiritoa reported 230mm from 4am Monday to 9.30am
today.
Many places had over 100mm in the upper North Island, with the majority in the 30 to 80mm mark.
Apart from Bay of Plenty, East Cape, Gisborne and northern Hawke's Bay, the next seven days ahead are looking drier than average (with those regions also falling into this category in another day or two).
