Severe gales attaining speeds of approximately 155km/h (96mph) have resulted in approximately 90,000 homes without power and led officials to cancel in excess of 100 flights, according to domestic outlets.
The winds are affecting the complete South Island and southern sections of the northern region, according to the country's meteorological service.
The nation's agencies have issued rare red wind warnings - the highest alert level - in core zones such as Wellington and Canterbury.
People have been encouraged to avoid going outside, refrain from journeys, and get ready for more electricity and network failures.

The electricity loss is primarily influencing residences mainly in the South Island, although officials state that power was being gradually reinstated.
Domestic outlets have indicated that in certain areas roofs have been ripped off houses, while utility poles and vegetation have been toppled by the gales.
