Intense gusts hitting velocities of approximately 155km/h (96mph) have resulted in around 90,000 households without power and led agencies to cancel over 100 air travel services, based on regional news sources.
These gusts are impacting the entire southern region and southern sections of the North Island, according to the national weather agency.
The nation's agencies have announced infrequent severe gust advisories - the most severe warning - in central regions encompassing Canterbury and Wellington.
People have been urged to remain inside, stay off roads, and prepare for additional electricity and network failures.
Widespread Damage and Emergency Measures
The power cut is primarily influencing households predominantly in the southern region, although officials say that the electricity supply was being gradually reinstated.
Regional news have indicated that in certain areas structures have suffered roof damage, whereas power lines and trees have been brought down by the gusts.
Within the capital, a person was fatally injured after being struck by a tree branch at a well-known hiking path on Tuesday.
Additionally in the city, a female was swept into moving cars on a thoroughfare by a strong gust of wind, in a moment that was captured in a viral dashcam video.
Aircraft services entering and leaving the city have been halted as a result of the weather, whereas certain highways and community centers are shut down.
Simultaneously authorities in Canterbury have issued a crisis declaration, to facilitate disaster response efforts.
Work Stoppages Amid Extreme Weather
The powerful gales on today come as many of educators, medical professionals and government employees are engaged in what has been termed a "major walkout", calling for higher wages and enhanced employment terms.
But the extreme weather has forced them to alter certain arrangements, with various open-air gatherings shifted to interior venues or abandoned.
