Powerful gusts reaching velocities of up to 155km/h (96mph) have caused approximately 90,000 homes experiencing outages and compelled officials to call off more than 100 flights, according to domestic outlets.
These gusts are impacting the complete South Island and southern sections of the North Island, per the country's meteorological service.
Officials in New Zealand have released infrequent severe gust advisories - the most severe warning - in central regions such as Wellington and Canterbury.
Locals have been urged to stay indoors, refrain from journeys, and prepare for further power and communication outages.
Broad Destruction and Crisis Measures
The electricity loss appears to be affecting homes mostly in the South Island, though officials report that energy was being restored progressively.
Local media have stated that in various locations homes have lost their roofs, while utility poles and vegetation have been knocked down by the gales.
In Wellington, a individual was killed after being hit by a wooden fragment at a well-known hiking path on Tuesday.

Meanwhile Canterbury officials have announced a emergency situation, to support recovery activities.
