Powerful winds hitting speeds of up to 155km/h (96mph) have resulted in around 90,000 properties lacking electricity and compelled agencies to call off in excess of 100 air travel services, based on domestic outlets.
The winds are affecting the complete South Island and southern parts of the North Island, according to the country's meteorological service.
The nation's agencies have released rare severe gust advisories - the top caution category - in key areas including Wellington and Canterbury.
People have been advised to stay indoors, avoid travel, and prepare for more electricity and network failures.
Widespread Damage and Crisis Response
The electricity loss is primarily influencing homes mostly in the southern region, although authorities say that power was being gradually reinstated.
Domestic outlets have reported that in some places homes have lost their roofs, whereas trees and electricity poles have been brought down by the gusts.
Within the capital, a individual was killed after being struck by a tree branch at a frequent walking route on earlier this week.
Meanwhile in Wellington, a individual was blown onto approaching vehicles on a road by a powerful blast, in a moment that was captured in a widely shared car camera footage.
Aircraft services to and from the metropolis have been suspended as a result of the weather, whereas certain highways and community centers are shut down.
Simultaneously local leaders have issued a crisis declaration, to assist disaster response efforts.
Work Stoppages Alongside Extreme Conditions
The powerful gales on today occur while many of educators, medical professionals and government employees take part in what has been termed a "significant labor action", demanding higher wages and enhanced employment terms.
Yet the extreme weather has compelled them to modify some of their plans, with various open-air gatherings moved indoors or cancelled.
Similar gusts are impacting the neighboring country, causing a heatwave to the remote areas.
Authorities have declared flame prohibitions for concern about bushfires.
