South Taranaki and Wanganui regions appear to have borne the brunt of the severe weather event that has now passed away to the east of the country.
The South Taranaki town of Patea woke up this morning to wild weather and loss of power.
Winds tore the roof from a local constable's police house.
His family evacuated to the police station.
Residents were told they could shelter at the town's fire station.
Several houses, shops and farm buildings lost their roofs.
In the town of Waverley the storm blew out the front wall of the old town hall, and battered buildings in the main street.
Nine roads were closed in Wanganui and there were many power outages as the storm lashed the city.
Damage in the region is being put in the millions of dollars.
