People in areas from the Waikato, Bay of Plenty down to the upper South Island are much more likely to need to get their umbrellas out from Tuesday night to Thursday morning.
Those places sheltered from the heavy dumps include Northland, Gisborne, Southland, Otago and southern parts of Canterbury.
However, rain relief may not come for the region arguably in need of it most as Auckland, which is in dire need of water with water restrictions in place since May is right on the cusp for heavier falls.
Auckland could instead be in for heavy wind and even gales from the north and west which could result in some power cuts from falling trees.
