Kiwis will need to get a blanket out or wear an extra layer over the coming days with a cold front expected to see temperatures plunge.
MetService said a strong southwest flow is expected to develop across the country on Wednesday and Thursday bringing wind watches for parts of New Zealand.
The forecaster said cold fronts will also lash New Zealand, which will keep the temperatures down.
MetService said temperatures will likely "feel" colder than forecasted as "strong southwesterlies will make wind chill a big factor".
Auckland will also be in the firing line over the next 48 hours, with MetService warning the City of Sails could see heavy showers and possible hail.
Weather warnings and watches
A strong wind watch is in place for the top of the North Island, with Northland south of Kawakawa, Auckland including Great Barrier Island, Coromandel Peninsula and Waikato north of Huntly all expected to see southwest winds, which could approach severe gale in exposed places.
The watch is in place from 1am to 11am on Wednesday for these areas.
Strong wind is also expected to lash Coastal areas from Tokomaru Bay to Wairoa, with a watch in place from 7am to 7pm on Wednesday.
The strong wind will move down the country on Thursday with a watch issued for Dunedin and North Otago from 6am to 3pm.
Further south, Clutha and Southland south of Lumsden including Stewart Island is also in the firing line with a strong wind watch in place from 11pm on Wednesday until 1pm on Thursday.
A road snowfall warning is in place for some of New Zealand's most iconic roads.
The warning is in place for Desert Road (SH1), Lewis Pass (SH7), Porters Pass (SH73), Lindis Pass (SH8), Milford Road (SH94) and Crown Range Rd.
The warnings are in place until 6pm on Tuesday for Lindis Pass and Milford Road, early Wednesday morning for Lewis Pass, Porters Pass and Crown Range Road and 3pm on Wednesday for the Desert Road.
This new cold front comes after parts of Canterbury experienced record-breaking rainfall at the weekend.
The wild weather saw specialist rescue crews called to McLaughlins Rd in the Canterbury town of Darfield after a person was trapped by floodwaters while driving.
The person needed to climb onto the vehicle's roof and was subsequently treated by St John.
