Enjoy the last day of the last long weekend of summer - it's going to be a good one.

Metservice duty forecaster Rochelle Fleming said this morning the settled weather around the country this long Waitangi weekend will continue on its final day.

"More of the same, so that means it's going to be a pretty good day for us."

A ridge of high pressure was over the country, bringing fine summer days for most.


In Hamilton, where the Black Caps will this afternoon and evening battle Australia in the Chappell-Hadlee series' decider, fans can expect to see a full game, Mrs Fleming said.

"It's a bit cloudy this morning, but it's just starting to break up so it should only get better."

The easterly flow over the northern half of the island could mean showers when it met seabreezes in the west, so there was a risk of showers in western Waikato, but Seddon Park was unlikely to be affected, she said.

Auckland's warm and humid summer continues, with morning cloud clearing through the day and a high of 26C expected. The temperature was just under 20C and humidity at 93 per cent at 8am.

Wellington could expect a stunner, with little wind, sunshine and a high in the mid-20s.

The Metservice are also keeping an eye on a low expected to deepen between Vanuatu and Fiji tomorrow and Wednesday, and with a moderate to high potential of developing into a tropical cyclone by the end of Thursday. Another low south of the Solomon Islands may also deepen this week and has a moderate potential of developing into a tropical cyclone by the same time.

There was still a lot of uncertainty about what would happen, and whether New Zealand would be affected, Mrs Fleming said.
