Intense winds hitting speeds of up to 155km/h (96mph) have left approximately 90,000 households lacking electricity and led agencies to halt more than 100 air travel services, as reported by regional news sources.
The winds are affecting the entire South Island and southern parts of the northern region, as stated by the national weather agency.
The nation's agencies have issued uncommon severe gust advisories - the most severe warning - in central regions such as Canterbury and Wellington.
Residents have been urged to remain inside, stay off roads, and get ready for further electricity and network failures.
Widespread Destruction and Emergency Measures
The electricity loss is primarily influencing homes mainly in the southern region, though agencies say that the electricity supply was being gradually reinstated.
Regional news have stated that in some places roofs have been ripped off houses, while utility poles and vegetation have been brought down by the gales.
Across Wellington, a individual was killed after being impacted by a falling limb at a well-known hiking path on Tuesday.
Additionally in the city, a woman was pushed toward moving cars on a thoroughfare by a powerful blast, in a moment that was captured in a popular vehicle recording.
Air travel to and from the urban area have been cancelled because of the gusts, while some roads and libraries are also closed.
At the same time authorities in Canterbury have issued a crisis declaration, to support disaster response efforts.
Strike Action Alongside Extreme Weather
The wild winds on Thursday occur while tens of thousands of educators, medical professionals and government employees are engaged in what has been called a "mega strike", requesting better pay and working conditions.
However the extreme weather has compelled them to alter certain arrangements, with various open-air gatherings relocated inside or called off.
Similar gusts are impacting the nearby nation, causing a heatwave to the country's outback.
Officials have issued fire bans for apprehension regarding bushfires.
