Severe gales attaining velocities of approximately 155km/h (96mph) have resulted in around 90,000 properties experiencing outages and compelled agencies to halt in excess of 100 flights, as reported by local media.
The winds are impacting the entire South Island and southern sections of the North Island, per the national weather agency.
The nation's agencies have released infrequent red wind warnings - the most severe warning - in core zones encompassing Canterbury and Wellington.
People have been encouraged to stay indoors, avoid travel, and make arrangements for further power and communication outages.
Extensive Impact and Emergency Measures
This outage seems to be impacting households mostly in the South Island, while authorities say that the electricity supply was being gradually reinstated.
Regional news have stated that in some places structures have suffered roof damage, while trees and electricity poles have been knocked down by the gales.
Across Wellington, a man was fatally injured after being hit by a wooden fragment at a well-known hiking path on Tuesday.
Also in the capital, a woman was swept into oncoming traffic on a street by a intensive burst, in a incident that was recorded in a widely shared car camera footage.
Air travel in and out of the city have been suspended because of the gusts, whereas various routes and public facilities are also closed.
At the same time authorities in Canterbury have declared a emergency situation, to support emergency management operations.
Strike Action Alongside Extreme Weather
The powerful gales on this day come as tens of thousands of school staff, physicians and civil servants are participating in what has been termed a "mega strike", requesting better pay and working conditions.
But the extreme weather has compelled them to modify some of their plans, with some outdoor rallies moved indoors or called off.
Like conditions are also sweeping the nearby nation, ushering in a heatwave to the country's outback.
Officials have declared fire bans for apprehension regarding forest fires.
