Powerful gales reaching velocities of approximately 155km/h (96mph) have resulted in around 90,000 homes without power and compelled officials to call off over 100 air travel services, as reported by regional news sources.
The winds are affecting the whole South Island and southern sections of the northern region, per the weather forecasting body.
The nation's agencies have announced rare red wind warnings - the top caution category - in central regions such as Wellington and Canterbury.
People have been encouraged to remain inside, stay off roads, and get ready for more electricity and network failures.
Extensive Destruction and Crisis Measures
The power cut is primarily influencing residences mainly in the South Island, though authorities say that power was being gradually reinstated.
Local media have indicated that in various locations homes have lost their roofs, and power lines and trees have been brought down by the gales.
Across Wellington, a man was killed after being struck by a falling limb at a frequent walking route on earlier this week.
Additionally in the city, a female was pushed toward moving cars on a thoroughfare by a intensive burst, in a moment that was captured in a popular vehicle recording.
Flights to and from the city have been suspended as a result of the weather, while certain highways and community centers are not operating.
Simultaneously local leaders have issued a crisis declaration, to assist emergency management operations.
Strike Action Alongside Extreme Conditions
The wild winds on Thursday occur while tens of thousands of teachers, doctors and other public workers take part in what has been described as a "mega strike", calling for better pay and working conditions.
But the extreme weather has compelled them to change various scheduled activities, with some outdoor rallies shifted to interior venues or called off.
Comparable winds are also sweeping the neighboring country, bringing a high-temperature event to the remote areas.
Authorities have declared burning restrictions for apprehension regarding forest fires.
