An ex-tropical cyclone is heading straight towards New Zealand and should bring heavy rain and wind to the North Island.
The remains of Tropical Cyclone June, which formed on Friday night north west of New Caledonia, should reach the upper North Island late tomorrow night and cross over the North Island on Tuesday as a sub-tropical low.
The low was not expected to be an extreme event, but was likely to bring a period of heavy rain to parts of the North Island and upper South Island from late tomorrow through to early Wednesday as it passes southeast, Met Service said.
In addition, a period of strong to gale northeasterlies were expected ahead of the low as it moved fast across the north of the country.
But while many parts of the North Island would be in for a drenching, there was no cause for concern.
"We are not looking at a really strong event at this stage. It is a baby in the big scheme of things and is already showing signs of weakening. At this point there is no reason for people to be batoning down the hatches. People should keep an eye on the forecast," duty forecaster Leigh Matheson said.
