Severe gales attaining velocities of approximately 155km/h (96mph) have resulted in around 90,000 properties lacking electricity and led agencies to halt over 100 air travel services, as reported by domestic outlets.
The winds are impacting the entire southern region and southern sections of the northern region, as stated by the weather forecasting body.
The nation's agencies have announced infrequent red wind warnings - the highest alert level - in key areas including Canterbury and Wellington.
People have been encouraged to stay indoors, refrain from journeys, and prepare for further electricity and network failures.
Widespread Damage and Emergency Response
This outage appears to be affecting homes mostly in the southern region, while officials report that the electricity supply was being restored progressively.
Regional news have indicated that in various locations homes have lost their roofs, and utility poles and vegetation have been knocked down by the gales.
Across Wellington, a person was killed after being hit by a tree branch at a frequent walking route on earlier this week.
Meanwhile in Wellington, a female was blown onto moving cars on a road by a intensive burst, in a moment that was recorded in a popular vehicle recording.
Aircraft services to and from the city have been halted because of the weather, while certain highways and community centers are shut down.
Simultaneously Canterbury officials have issued a state of emergency, to support emergency management operations.
Strike Action Alongside Extreme Weather
The wild winds on Thursday come as tens of thousands of teachers, doctors and other public workers take part in what has been called a "significant labor action", calling for better pay and working conditions.
However the intense climate has forced them to modify some of their plans, with some outdoor rallies shifted to interior venues or abandoned.
Comparable winds are affecting the neighboring country, ushering in a high-temperature event to the remote areas.
Agencies have issued burning restrictions for apprehension regarding bushfires.
