The upper half of New Zealand currently sits under a large ridge of high pressure – extending across the nation from way out in the Tasman sea. Due to some seasonal “upper level” cooling, there IS a risk of some afternoon showers, possible heavy downpours and even thunderstorms in some areas.
The upper half of the North Island can expect sunny spells, areas of cloud, light winds and some afternoon sea breezes – but nothing too dramatic.
During the afternoon, the Waikato region and all the way down between New Plymouth and Lake Taupo can expect some isolated (and possibly heavy) showers in the afternoon, which could become thunderstorms – but this should clear up by evening. The temperatures should stay fairly mild, though – sitting around the late teens for most.
On the East Coast and around Whanganui southwards, the pattern of sunny weather should continue – just some light sea breezes in the afternoon.
