Another bout of heavy rain was expected to hit the North Island on Tuesday morning.
The Wellington region was drenched yesterday, causing slips which evacuated homes and strong winds felled a tree in Tawa, blocking the main road.
WeatherWatch said weak La Nina conditions were sweeping across the country, bringing wet weather to many North Island areas, as well as parts of the South Island.
The weather patterns were expected to continue into the summer season.
Typically, La Niña brought warmer land and sea temperatures but also more rain.
So Kiwis could expect cloudier weather in coastal areas, afternoon showers inland and an abundance of easterlies this summer, WeatherWatch said.
