Severe gusts attaining velocities of up to 155km/h (96mph) have caused nearly 90,000 properties experiencing outages and forced authorities to call off more than 100 air travel services, based on domestic outlets.
These gusts are influencing the whole southern region and southern parts of the North Island, per the country's meteorological service.
The nation's agencies have issued rare severe gust advisories - the most severe warning - in central regions encompassing Wellington and Canterbury.
Locals have been urged to stay indoors, stay off roads, and make arrangements for more utility disruptions.
Broad Impact and Emergency Measures
The power cut appears to be affecting homes mostly in the southern region, although authorities say that the electricity supply was being gradually reinstated.
Local media have indicated that in various locations roofs have been ripped off houses, whereas power lines and trees have been brought down by the gales.
Across Wellington, a individual was killed after being impacted by a tree branch at a well-known hiking path on earlier this week.
Meanwhile in Wellington, a woman was pushed toward approaching vehicles on a street by a strong gust of wind, in a moment that was captured in a popular vehicle recording.
Flights in and out of the urban area have been suspended as a result of the gusts, and certain highways and community centers are not operating.
At the same time Canterbury officials have declared a state of emergency, to facilitate disaster response efforts.
Strike Action Amid Severe Weather
These intense gusts on today coincide with tens of thousands of teachers, doctors and other public workers take part in what has been called a "significant labor action", requesting better pay and working conditions.
But the extreme weather has pressured them to change some of their plans, with several external protests moved indoors or cancelled.
Comparable winds are also sweeping the neighboring country, causing a heatwave to the nation's interior regions.
Authorities have declared fire bans for concern about bushfires.
