The upper North Island has been rocked by strong winds overnight, leaving several communities without power.
MetService issued a severe weather warning for the upper North Island last night.
A strong southwesterly flow over the upper North Island created severe gusts, with the strongest winds recorded between 7pm on Sunday night and 2am on Monday morning.
The Hauraki Gulf and other exposed areas saw gusts of up to 110km/h, while urban areas in and around Auckland City experienced 90km/h gusts.
Power to Silverdale and Waitoki, north of Auckland, was knocked out at 2am and is not expected to be restored until 5pm today, according to Vector.
Power was also cut to parts of Titirangi, Glendowie, Kumeu and Muriwai.
An outage near Dairy Flat this morning has now been restored.
MetService meteorologist Sarah Haddon said the severe winds "would have felt even worse" because of the accompanying rain and occasional lightning.
She said the upper North Island should see an "easing trend throughout the whole day", with winds dying down and showers easing off by the evening.
Wild weather caused chaos at the New Zealand Women's Open at Windross Farm yesterday, with hoardings flying across the course and a Sky Television contractor falling down a bank.
