Rain spreading to most places, and snow to low levels for inland South Island areas, but only scattered falls in the east of the North Island. Rain clearing in the west of the South Island later, and easing to showers in the far south.
Sunday
North Island, showers in most places, some possibly heavy from Northland to Taranaki and about the Central Plateau. South Island, becoming fine in most places, but still some showers about coastal Marlborough and near Foveaux Strait.
Chatham Islands
Fine spells on Friday, and northwesterlies developing. Becoming cloudy on Saturday. Rain and strengthening northerlies on Sunday.

Another weekend and another wind and rain maker is coming in - but it's like a baby version of the storm we had last weekend. While some rain warnings are in force - and some further rain and wind warnings may be issued - it's a much smaller system than the storm we had last weekend and early this week.
However it does have similarities - Windy weather in the east, wet in the west and north, and a potential cold snap early next week (but nothing like this week).

Saturday is still looking similar as projected in yesterday afternoon’s outlook but Sunday however is really turning into a mixed bag. We have a low pressure system developing out west of New Zealand today on a front moving into the Tasman Sea, on Saturday the low looks fairly organised and moving eastwards. But during the course of Sunday it begins to tire from afternoon and loses it’s strength somewhat, but some places may still pack a punch, as Phil put it once the energy gets spread out and not so concentrated as these lows unwind.

So for Saturday it is much the same but a few changes. Skies will be mostly cloudy over the North Island with brisk northerly winds, rain develops in the west during the afternoon then clears later in the day as winds change westerly west of about Waikato. Fine out east with high cloud and breezy northerlies, a few spots of rain possible at night.
Fine on the east coast of the South Island with high cloud, showers in Southland and Otago move through into Canterbury and Marlborough in the evening with south to southeast winds. Rain for the West Coast with heavy falls in South Westland.
On Sunday the front over the North Island may stall about Bay Of Plenty particularly in the east due to the blocking nature of the high out to the east of the country, so keep an eye out for possible heavy rain warnings on Sunday for that area. Expect sunny areas and some cloud for the rest of the North Island with northerly breezes, a few isolated showers developing late afternoon or evening in the west. A few of those showers could be heavy and thundery then clearing at night. The Wairarapa and Wellington will remain largely dry with northerlies, cloudy north of Hawkes Bay with some rain from afternoon.
For the South Island on Sunday there is likely to be a few areas of rain for the upper half of the Island, particularly in the likes of Nelson and the surrounding ranges. There may also be sunny breaks also, winds will be variable but mainly from the northerly quarter. Southland and Fiordland will likely remain dry with some sun and light winds, other areas from Canterbury down through to Otago are likely to experience sunny areas and some cloud with winds tending southerly or southwesterly. There may be a few showers about mainly in the morning.

The low tracking slowly across the Tasman will still be to our west tomorrow. That means another day of clouds, wind and rain.

The threat for heavy rainfall will still be around tomorrow, but the main focus will shift the eastern North Island where the eastern Bay of Plenty and northern Gisborne will be most likely to see heavy showers.
In fact, Government forecaster MetService has a warning in place for heavy rain for the Bay of Plenty east of Kawerau. Rainfall rates could reach 20mm/hr tomorrow. Whilst northern Gisborne is not under a warning at this time, it is possible would could be required tonight or tomorrow.
The western North Island could actually see a bit of break in the precipitation tomorrow morning and early tomorrow afternoon, even though Auckland, Hamilton and Whangarei may see a few quick showers pass through during the morning hours.
But during the afternoon tomorrow, another band of wind and rain is expected for the western North Island. Winds will pick up again as well. Some brief heavy falls are possible about Auckland and Taranaki, especially late the afternoon.
On the South Island, there is a small threat for heavy rain about Nelson during the evening hours. Just some general shower activity is expected for the rest of the upper half of the Mainland during the morning and afternoon.
Southland and Otago will probably not see much in the way of precipitation tomorrow. Maybe a few brief showers in the morning. However, as Sunday wears on, those precipitation chances will diminish.
