A tropical low is expected to strike New Zealand next week, bringing "severe weather" to northern and eastern parts of the country.
The "broad and deep" low-pressure system is forecast to approach the North Island from the north Tasman Sea on Monday and then slowly move southeast across the northern half of the North Island.
This system is predicted to bring widespread rain to the North Island and the upper South Island, with the heaviest falls expected in the northern and eastern districts.
"As the deep low approaches the Far North for the start of term four, southeasterly winds will rise to gale force over northern New Zealand, bringing heavy rain to Northland," MetService says.
"The low is expected to become slow-moving over northern New Zealand on Tuesday, with an associated front spreading rain as far south as Marlborough.
"Heavy rain continues in the north and is also likely about eastern areas of the North Island on Tuesday, with strong to gale-force winds forecast for much of the North Island."
MetService warns severe weather warnings and watches will likely be issued for this event.
