Powerful gales reaching velocities of up to 155km/h (96mph) have resulted in nearly 90,000 properties without power and compelled agencies to cancel in excess of 100 flights, based on domestic outlets.
The winds are influencing the whole southern region and southern sections of the North Island, according to the national weather agency.
The nation's agencies have issued infrequent high-level wind alerts - the most severe warning - in core zones such as Canterbury and Wellington.
Residents have been encouraged to remain inside, refrain from journeys, and prepare for further utility disruptions.
Widespread Destruction and Crisis Response
The power cut seems to be impacting households mostly in the South Island, although agencies report that the electricity supply was being slowly brought back.
Domestic outlets have indicated that in some places structures have suffered roof damage, while trees and electricity poles have been brought down by the gales.
Across Wellington, a person was lost his life after being struck by a wooden fragment at a frequent walking route on Tuesday.
Meanwhile in Wellington, a individual was swept into moving cars on a street by a intensive burst, in a incident that was captured in a widely shared car camera footage.
Aircraft services in and out of the city have been halted as a result of the gusts, and some roads and libraries are shut down.
Simultaneously authorities in Canterbury have declared a emergency situation, to facilitate emergency management operations.
Labor Protests Alongside Severe Conditions
The wild winds on this day coincide with tens of thousands of educators, medical professionals and government employees are participating in what has been called a "significant labor action", requesting improved salaries and workplace environments.
However the extreme weather has pressured them to change various scheduled activities, with various open-air gatherings moved indoors or cancelled.
Comparable winds are also sweeping Australia, ushering in a period of extreme heat to the nation's interior regions.
Agencies have declared burning restrictions for concern about bushfires.
