The mercury will rise into the mid 20s this afternoon around parts of Waikato, Auckland, Coromandel and Western Bay of Plenty.
Showers will mainly feature across those same regions, though, mostly in the Bombay Hills area near the end of Auckland's Southern Motorway.
Cloudy spells are also affecting the eastern side of the South Island. Christchurch brightened up a bit yesterday but the past few days have been fairly cloudy at times despite no rain for the dry region.
Napier yesterday had drizzle patches but today looked drier.
A huge high parked over New Zealand means the first day of autumn is set to be similar to the last day of summer.
The high remains over the country until Friday. Over the weekend the high pressure balloon pops as a fairly light south west flow moves in.
The next big high appears to be around next Wednesday, mostly for the South Island and lower North Island.
And as tropical rainmakers try to push down towards New Zealand this second high will push back.
A battle of the pressure systems will happen over the North Island between dry high pressure and humid, wet sub-tropical air that is trying to sink towards the North Island towards mid-March. It's too early to know which system will win.
