Intense gusts attaining speeds of as high as 155km/h (96mph) have resulted in around 90,000 homes experiencing outages and compelled agencies to cancel more than 100 aircraft departures, based on domestic outlets.
The winds are affecting the entire southern region and southern sections of the North Island, according to the national weather agency.
The nation's agencies have issued infrequent severe gust advisories - the most severe warning - in key areas such as Canterbury and Wellington.
Locals have been advised to avoid going outside, refrain from journeys, and prepare for further utility disruptions.
Extensive Damage and Emergency Measures
The electricity loss appears to be affecting households predominantly in the southern region, though authorities state that the electricity supply was being slowly brought back.
Regional news have reported that in certain areas homes have lost their roofs, and trees and electricity poles have been brought down by the gusts.
Across Wellington, a person was fatally injured after being struck by a falling limb at a frequent walking route on earlier this week.
Meanwhile in Wellington, a individual was blown onto oncoming traffic on a road by a strong gust of wind, in a incident that was recorded in a viral dashcam video.
Flights in and out of the metropolis have been halted because of the gusts, whereas some roads and libraries are also closed.
At the same time Canterbury officials have declared a emergency situation, to facilitate recovery activities.
Labor Protests Amid Extreme Conditions
The powerful gales on this day occur while tens of thousands of educators, medical professionals and government employees are participating in what has been called a "mega strike", calling for better pay and working conditions.
Yet the intense climate has compelled them to modify various scheduled activities, with some outdoor rallies shifted to interior venues or called off.
Like conditions are also sweeping the neighboring country, bringing a period of extreme heat to the country's outback.
Officials have issued burning restrictions for apprehension regarding wildfires.
