Severe winds hitting speeds of up to 155km/h (96mph) have resulted in around 90,000 households experiencing outages and forced officials to call off over 100 air travel services, as reported by local media.
These gusts are impacting the whole southern region and southern sections of the northern region, per the national weather agency.
The nation's agencies have issued rare severe gust advisories - the highest alert level - in core zones such as Canterbury and Wellington.
Residents have been advised to remain inside, avoid travel, and get ready for additional power and communication outages.
Extensive Impact and Crisis Measures
This outage seems to be impacting households mainly in the South Island, though authorities say that the electricity supply was being restored progressively.
Local media have indicated that in some places homes have lost their roofs, whereas power lines and trees have been knocked down by the gusts.
Across Wellington, a man was lost his life after being struck by a falling limb at a well-known hiking path on earlier this week.

Flights in and out of the city have been cancelled because of the gusts, whereas some roads and libraries are not operating.
Simultaneously authorities in Canterbury have declared a crisis declaration, to facilitate disaster response efforts.
Labor Protests During Extreme Weather
