Unsettled weather is forecast to continue this week, with blue skies tomorrow followed by more grey and damp, MetService says.
Meteorologist Liz Walsh said a wet front looming over Auckland this afternoon was gradually weakening as it moved across the North Island.
Likewise, the South Island had seen an active front move up the east coast bringing thundery activity to places.
"But it looks like everything's easing back to open up a pretty nice day over the North Island tomorrow with lots of sunshine and temperatures heading up into the mid 20s,'' she said.
Most of the South Island, apart from Fiordland and Southland, could also expect reasonably fine weather tomorrow until another front rolled over in the evening.
"That front will head up the North Island on Tuesday and then we're left with a disturbed south to south-west flow on Wednesday and Thursday, which means showers and passing cloud, particularly for Auckland.''
Temperatures this week looked set to remain in the mid to low 20s and projections for next weekend were starting to look a bit more settled.
"But the jury's still out on the rest of January. We're looking for a big blocking high on the horizon but it hasn't reared its head yet so we're hoping for that.''
