Severe gales hitting velocities of up to 155km/h (96mph) have caused nearly 90,000 households without power and compelled agencies to cancel over 100 flights, as reported by local media.
These gusts are affecting the entire southern region and southern sections of the northern region, according to the national weather agency.
The nation's agencies have announced rare high-level wind alerts - the highest alert level - in core zones including Wellington and Canterbury.
People have been advised to avoid going outside, refrain from journeys, and get ready for additional electricity and network failures.
Widespread Damage and Emergency Response
The electricity loss is primarily influencing households predominantly in the South Island, while authorities report that energy was being restored progressively.
Regional news have reported that in certain areas structures have suffered roof damage, whereas power lines and trees have been brought down by the winds.
In Wellington, a man was fatally injured after being struck by a tree branch at a frequent walking route on earlier this week.

Aircraft services in and out of the urban area have been suspended because of the weather, and some roads and libraries are shut down.
Meanwhile local leaders have announced a crisis declaration, to facilitate recovery activities.
