"We're not going to find much rain anywhere in New Zealand, which is a concern for the likes of the Waikato and Auckland which have had a really dry month and more dry weather to come," he said.
Conditions in the capital would be cloudy but dry, with much the same on the east coast of the North Island.
WeatherWatch head analyst Philip Duncan said the country was in for "much calmer" weekend.
But a southerly moving up the country on Saturday morning would cool temperatures in the South Island throughout the day.
The weather in Auckland would be "fantastic" for the Pasifika festival, but the weekend would close with showers on Sunday evening, he said.
