However the wet would be nothing like what was seen earlier this week, when severe downpours caused flooding in some areas and strong winds.
"There is a chance of heavy rain in Westland on Tuesday but that's pretty standard for them," Glassey said.
By Wednesday most of the rain should be confined to central New Zealand - the top half of the South Island and the mid to lower half of the North Island.
Today, a low-risk thunderstorm outlook and chance of heavy rain was in place for Coromandel Peninsula south of Tairua and the Bay of Plenty west of Whakatane until noon.
Most of the country was forecast to have a partly sunny day marred by cloud and drizzle.
