Intense gusts reaching speeds of up to 155km/h (96mph) have caused around 90,000 households without power and forced officials to halt more than 100 air travel services, based on local media.
The winds are impacting the complete southern region and southern sections of the North Island, as stated by the country's meteorological service.
The nation's agencies have released infrequent high-level wind alerts - the most severe warning - in key areas encompassing Canterbury and Wellington.
Locals have been advised to remain inside, avoid travel, and make arrangements for more electricity and network failures.
Widespread Damage and Crisis Response
This outage appears to be affecting households mainly in the South Island, though officials state that energy was being gradually reinstated.
Domestic outlets have stated that in various locations roofs have been ripped off houses, and trees and electricity poles have been knocked down by the gales.
In Wellington, a man was fatally injured after being struck by a wooden fragment at a frequent walking route on earlier this week.
Additionally in the city, a female was blown onto moving cars on a street by a intensive burst, in a event that was filmed in a widely shared car camera footage.
Flights to and from the city have been suspended as a result of the gusts, and various routes and public facilities are not operating.
Simultaneously Canterbury officials have announced a state of emergency, to support emergency management operations.
Strike Action Alongside Severe Weather
The powerful gales on this day come as many of school staff, physicians and civil servants are engaged in what has been described as a "significant labor action", requesting higher wages and enhanced employment terms.
Yet the intense climate has forced them to change certain arrangements, with some outdoor rallies shifted to interior venues or abandoned.
Like conditions are also sweeping the neighboring country, causing a high-temperature event to the nation's interior regions.
