Intense winds hitting speeds of up to 155km/h (96mph) have resulted in approximately 90,000 properties lacking electricity and compelled officials to call off in excess of 100 flights, based on regional news sources.
These gusts are affecting the entire southern region and southern sections of the North Island, per the national weather agency.
The nation's agencies have issued rare severe gust advisories - the most severe warning - in central regions including Wellington and Canterbury.
Residents have been urged to avoid going outside, refrain from journeys, and prepare for additional electricity and network failures.
Broad Impact and Crisis Response
This outage seems to be impacting residences mainly in the southern region, while officials say that power was being gradually reinstated.
Domestic outlets have indicated that in some places homes have lost their roofs, and power lines and trees have been toppled by the gales.
Across Wellington, a person was killed after being hit by a falling limb at a frequent walking route on earlier this week.
Meanwhile in Wellington, a woman was pushed toward moving cars on a road by a strong gust of wind, in a incident that was recorded in a popular vehicle recording.
Air travel to and from the metropolis have been cancelled due to the weather, while various routes and public facilities are shut down.
Meanwhile Canterbury officials have announced a emergency situation, to assist emergency management operations.
Work Stoppages Amid Severe Weather
The powerful gales on Thursday come as tens of thousands of educators, medical professionals and government employees are engaged in what has been called a "major walkout", calling for higher wages and enhanced employment terms.
However the extreme weather has compelled them to change some of their plans, with several external protests moved indoors or called off.
