A high of 13C is expected in the City of Sails and an overnight low of 8C is on the cards.
There is, however, a chance of showers north of the city before clouds come in later this evening.
It was a chilly night and early morning for many areas, including parts of the North Island.
MetService meteorologist Sarah Haddon said the coldest populated area early this morning - just before dawn, which is the coldest time, she said - was Alexandra, in
Central Otago.
A teeth-shattering -5C was recorded there about 6.45am. Dunedin was the second coldest place at -4.5C.
Those in Auckland were in for a cold wake-up call, with 3C recorded early today; while those in Wellington and Christchurch were in for 1C and -1C, respectively.
"Overall, it's fine for most of the country - it's sunny skies,'' Haddon said.

A northerly airflow set to gradually increase today and tomorrow morning would bring somewhat warmer temperatures, she said.
However, rain is also in the forecast.
The warmest place recorded early today was in Whangārei, which saw 12C.
Haddon said much of Northland and parts of the east coast - including Gisborne - had temperatures ranging between 10C to 12C.
"Northland has had cloud overnight, so it kind of acts as a blanket."
Wet and windy conditions ahead
The MetService has issued a severe weather outlook for the next few days - with an active front set to move east across the country from the Tasman Sea tomorrow. A slow-moving low pressure system is then expected to come in on Wednesday through to Friday.
"These weather systems are expected to bring rain to many parts of the country, with the heaviest falls about the western regions of the South Island and central and southern districts of the North Island," MetService said.
There is moderate confidence of "warning amounts" of rain in Westland and Fiordland tomorrow and then again in Westland on Wednesday and Thursday.
"The risk for warning amounts of rain in northwest Nelson is low on Tuesday - then again on Wednesday and the risk area extending south across of all of Buller, with the risk increasing to moderate on Thursday.
As well as heavy rains predicted, there is moderate confidence of severe north to northeast gales affecting inland parts of Marlborough, the Canterbury High Country, the Otago Lakes, Westland and Fiordland.
