States of emergency have also been declared in Nelson, Westland, Buller, Greymouth, Selwyn and Christchurch as Cyclone Gita hits the country.
The storm is now hammering Taranaki and the West Coast with winds of up to 150 kilometres an hour.
Lines company Powerco said fallen trees and branches had cut power throughout the region and wind gusts of up to 140km/h were making repair work difficult.
Some people may be without power overnight and into tomorrow.
A fallen tree has ruptured the pipeline from the New Plymouth water treatment plant to the Mangorei reservoir and residents in the city's east are being urged to conserve water.
Gita touched down in Taranaki on schedule at 3pm this afternoon and the wind has been steadily rising since.
Emergency services are dealing with multiple downed trees and powerlines.
A tree fell onto a car with a woman inside in Stratford, while a truck was flipped on its side in Opunake.
Both drivers had miraclulous escapes.
The Hawera fire chief Mike Fairweather said his staff had attended multiple reports of lifting roofs and downed trees.
Taranaki Port has been closed from 10am.
Strong winds and high tides
MetService warned high tides overnight were likely to bring large waves to Taranaki about 2am.
Severe gales are expected to hit Taranaki, Taihape and Whanganui, and the lower North Island. Nelson and Buller, Marlborough, Westland and Canterbury are also expected to get severe south to south east gales.
Niwa is predicting gusts up to between 130 and 150km/h will peak around 10.30pm.
It said the wind would start to rise rapidly from about 4pm and should drop significantly by 4am tomorrow.
Tides, strong winds and heavy rain could bring storm surges and waves up to 6m high.

Communication wires are also at risk, with Chorus saying it had checked and re-fuelled the generators in its exchanges and put portable generators in areas where the weather is expected to be at its worst - in case power failed.
