Severe gales reaching speeds of approximately 155km/h (96mph) have left nearly 90,000 households lacking electricity and led authorities to cancel more than 100 flights, based on local media.
The gales are affecting the complete South Island and southern parts of the northern region, as stated by the country's meteorological service.
The nation's agencies have announced infrequent severe gust advisories - the highest alert level - in core zones including Canterbury and Wellington.
Residents have been encouraged to avoid going outside, stay off roads, and prepare for further power and communication outages.
Broad Destruction and Emergency Measures
The power cut seems to be impacting households mostly in the South Island, though agencies say that power was being restored progressively.
Local media have stated that in some places roofs have been ripped off houses, and trees and electricity poles have been knocked down by the gusts.
Across Wellington, a individual was lost his life after being impacted by a falling limb at a frequent walking route on earlier this week.
Also in the capital, a woman was swept into moving cars on a street by a intensive burst, in a event that was filmed in a widely shared car camera footage.
Aircraft services in and out of the metropolis have been suspended because of the gusts, whereas some roads and libraries are shut down.
At the same time authorities in Canterbury have announced a emergency situation, to support disaster response efforts.
Strike Action Alongside Extreme Weather
These intense gusts on this day come as many of school staff, physicians and civil servants are engaged in what has been termed a "significant labor action", calling for better pay and working conditions.
But the intense climate has compelled them to modify certain arrangements, with some outdoor rallies shifted to interior venues or abandoned.
Similar gusts are also sweeping the neighboring country, ushering in a high-temperature event to the country's outback.
Officials have issued burning restrictions for concern about wildfires.
