Powerful gusts attaining speeds of approximately 155km/h (96mph) have resulted in approximately 90,000 households without power and led officials to halt more than 100 air travel services, as reported by domestic outlets.
The gales are influencing the entire southern region and southern sections of the northern region, as stated by the country's meteorological service.
The nation's agencies have announced infrequent severe gust advisories - the most severe warning - in core zones including Canterbury and Wellington.
People have been advised to avoid going outside, avoid travel, and make arrangements for further utility disruptions.
Broad Destruction and Crisis Measures
The electricity loss seems to be impacting homes mainly in the southern region, while authorities state that the electricity supply was being slowly brought back.
Local media have reported that in certain areas homes have lost their roofs, whereas utility poles and vegetation have been brought down by the gales.
In Wellington, a individual was fatally injured after being impacted by a tree branch at a popular trail walking spot on earlier this week.
Additionally in the city, a woman was pushed toward approaching vehicles on a road by a powerful blast, in a moment that was recorded in a widely shared car camera footage.
Aircraft services to and from the metropolis have been cancelled because of the weather, while various routes and public facilities are shut down.
Meanwhile Canterbury officials have declared a state of emergency, to support emergency management operations.
Labor Protests Alongside Extreme Weather

Yet the extreme weather has forced them to modify various scheduled activities, with some outdoor rallies moved indoors or abandoned.
Similar gusts are also sweeping Australia, ushering in a period of extreme heat to the nation's interior regions.
