Waitangi Day celebrations in the Far North could be hampered by some showers, but it should be a good day elsewhere in the country, MetService says.
Meteorologist Daniel Corbett said there could well be a few showers during the day in Waitangi and Northland for events place there tomorrow.
"Waitangi Day should be a great day for outdoor plans over many parts of the country except the Far North and east, where there could be a wee bit of wet weather,'' he said,
The large high that has kept the rain at bay would gradually build across the South Island in the coming days.
However, by Friday a moist easterly flow, associated with a subtropical weather system, was likely to sink down from the Far North across central parts of the North Island to bring spells of rain or showers.
