Intense winds hitting speeds of as high as 155km/h (96mph) have caused nearly 90,000 properties lacking electricity and forced officials to halt more than 100 aircraft departures, based on regional news sources.
These gusts are affecting the entire southern region and lower areas of the North Island, according to the national weather agency.
The nation's agencies have announced infrequent high-level wind alerts - the highest alert level - in core zones such as Wellington and Canterbury.
People have been encouraged to remain inside, stay off roads, and prepare for additional power and communication outages.
Extensive Impact and Crisis Measures
The power cut seems to be impacting residences mostly in the southern region, while authorities say that the electricity supply was being gradually reinstated.
Regional news have reported that in some places structures have suffered roof damage, while trees and electricity poles have been knocked down by the gusts.
Across Wellington, a man was fatally injured after being struck by a wooden fragment at a frequent walking route on Tuesday.
Additionally in the city, a woman was pushed toward approaching vehicles on a thoroughfare by a intensive burst, in a event that was filmed in a widely shared car camera footage.
Aircraft services to and from the urban area have been halted due to the weather, while certain highways and community centers are not operating.
At the same time local leaders have issued a crisis declaration, to facilitate disaster response efforts.
Strike Action Alongside Extreme Conditions
These intense gusts on this day occur while many of educators, medical professionals and government employees take part in what has been called a "mega strike", demanding improved salaries and workplace environments.
But the intense climate has forced them to change some of their plans, with various open-air gatherings shifted to interior venues or abandoned.
Like conditions are also sweeping the nearby nation, causing a heatwave to the nation's interior regions.
Authorities have announced fire bans for fear of wildfires.
