A cold front pushes northwards over the South Island today, it weakens as it moves northwards meanwhile the North Island is under a ridge of high pressure.

North Island

Mostly dry with sun but there could be some cloud and a shower or two about coastal parts in the northeast (East Cape up through to Northland). There could also be some cloud in the southwest (Taranaki through to Kapiti) bringing the risk of a coastal shower there. Perhaps some morning fog for the North Island also, mainly about some inland parts then clearing. Later this evening and overnight cloud thickens in the south (Wellington) and eventually up the east coast with southerlies bringing a few light showers or drizzle patches.
