Intense gales attaining speeds of up to 155km/h (96mph) have left nearly 90,000 homes lacking electricity and forced agencies to cancel more than 100 air travel services, as reported by local media.
The gales are influencing the complete South Island and southern sections of the northern region, according to the national weather agency.
The nation's agencies have issued uncommon red wind warnings - the most severe warning - in core zones including Wellington and Canterbury.
People have been advised to remain inside, stay off roads, and prepare for further power and communication outages.
Extensive Destruction and Emergency Measures
The electricity loss appears to be affecting households predominantly in the southern region, although agencies say that the electricity supply was being gradually reinstated.
Regional news have indicated that in certain areas structures have suffered roof damage, and trees and electricity poles have been brought down by the winds.
Across Wellington, a person was fatally injured after being struck by a falling limb at a popular trail walking spot on earlier this week.
Also in the capital, a female was pushed toward moving cars on a thoroughfare by a intensive burst, in a incident that was captured in a popular vehicle recording.
Flights entering and leaving the metropolis have been cancelled as a result of the winds, and some roads and libraries are not operating.
Meanwhile Canterbury officials have announced a state of emergency, to assist recovery activities.
Labor Protests During Harsh Weather
The powerful gales on this day coincide with tens of thousands of school staff, physicians and civil servants take part in what has been described as a "major walkout", demanding improved salaries and workplace environments.
But the intense climate has forced them to modify certain arrangements, with various open-air gatherings relocated inside or called off.
Like conditions are also sweeping the neighboring country, ushering in a period of extreme heat to the country's outback.
Authorities have announced flame prohibitions for concern about wildfires.
