Intense winds reaching speeds of up to 155km/h (96mph) have left nearly 90,000 properties lacking electricity and compelled agencies to halt in excess of 100 flights, according to local media.
These gusts are affecting the entire South Island and southern parts of the North Island, per the country's meteorological service.
New Zealand authorities have released infrequent severe gust advisories - the most severe warning - in key areas encompassing these major districts.
Residents have been encouraged to avoid going outside, refrain from journeys, and prepare for more utility disruptions.
Widespread Impact and Emergency Response
This outage seems to be impacting homes predominantly in the South Island, while officials report that the electricity supply was being gradually reinstated.
Domestic outlets have indicated that in certain areas roofs have been ripped off houses, whereas power lines and trees have been toppled by the gusts.

Flights entering and leaving the metropolis have been cancelled due to the gusts, and some roads and libraries are shut down.
Meanwhile local leaders have announced a state of emergency, to facilitate disaster response efforts.
