Powerful gales hitting speeds of up to 155km/h (96mph) have left around 90,000 homes lacking electricity and compelled authorities to halt over 100 flights, based on regional news sources.
These gusts are impacting the whole South Island and southern sections of the northern region, according to the weather forecasting body.
The nation's agencies have released uncommon high-level wind alerts - the highest alert level - in key areas such as Wellington and Canterbury.
People have been advised to avoid going outside, refrain from journeys, and make arrangements for further electricity and network failures.
Widespread Damage and Crisis Response
The power cut seems to be impacting households mostly in the southern region, although officials say that the electricity supply was being slowly brought back.
Regional news have indicated that in some places roofs have been ripped off houses, whereas utility poles and vegetation have been brought down by the gusts.
Across Wellington, a man was lost his life after being impacted by a falling limb at a popular trail walking spot on earlier this week.
Additionally in the city, a individual was blown onto oncoming traffic on a thoroughfare by a intensive burst, in a moment that was filmed in a viral dashcam video.
Flights to and from the urban area have been cancelled as a result of the winds, while various routes and public facilities are shut down.
Simultaneously authorities in Canterbury have issued a crisis declaration, to support emergency management operations.
Strike Action During Harsh Conditions
The powerful gales on this day come as many of educators, medical professionals and government employees take part in what has been described as a "major walkout", calling for improved salaries and workplace environments.
But the extreme weather has compelled them to modify certain arrangements, with some outdoor rallies moved indoors or abandoned.
Comparable winds are also sweeping Australia, causing a high-temperature event to the remote areas.
Authorities have announced fire bans for fear of bushfires.
