Intense gales attaining velocities of approximately 155km/h (96mph) have resulted in around 90,000 homes lacking electricity and compelled officials to cancel in excess of 100 aircraft departures, as reported by domestic outlets.
The gales are affecting the whole South Island and southern parts of the North Island, per the national weather agency.
The nation's agencies have announced rare red wind warnings - the top caution category - in key areas encompassing Wellington and Canterbury.
Residents have been advised to stay indoors, avoid travel, and make arrangements for additional power and communication outages.
Extensive Impact and Emergency Measures
The electricity loss is primarily influencing homes mainly in the South Island, while authorities state that energy was being restored progressively.
Domestic outlets have reported that in certain areas roofs have been ripped off houses, and trees and electricity poles have been toppled by the gales.
In Wellington, a person was killed after being impacted by a tree branch at a frequent walking route on earlier this week.
Also in the capital, a female was pushed toward approaching vehicles on a road by a intensive burst, in a moment that was captured in a viral dashcam video.
Aircraft services to and from the urban area have been halted because of the winds, while some roads and libraries are not operating.
Simultaneously authorities in Canterbury have issued a crisis declaration, to facilitate emergency management operations.
Work Stoppages Amid Harsh Weather
These intense gusts on this day occur while many of teachers, doctors and other public workers are engaged in what has been called a "significant labor action", calling for better pay and working conditions.
However the extreme weather has compelled them to change certain arrangements, with several external protests relocated inside or cancelled.
Comparable winds are also sweeping Australia, causing a period of extreme heat to the country's outback.
Officials have announced burning restrictions for concern about forest fires.
