Most places should see an improvement in weather conditions today as a frontal system moves off to the north east. A developing low north of New Zealand should move eastwards away from land meaning clearing skies spreading in behind.
The wind direction behind the front and low should be mostly light and drifting in from the south – that favours sunny weather for most places in the North Island, bar the east coast, while winds will die out completely for many in the South Island.
Little to no wind and clear skies means tonight will be colder for many with the risk of light frosts in sheltered inland places south of about Waikato.
A large anticyclone in the northern Tasman Sea should spread a ridge over the country bringing sunny, calm, weather for the rest of the week. But a weak low may develop in the northern Tasman Sea on Saturday bringing a few showers to northern New Zealand – possibly as far south as Auckland on Sunday.
