Electricity suppliers have managed to restore all of Auckland's power supply on Wednesday after ex-tropical Cyclone June's powerful wild winds hit the area on Tuesday.

The massive power outage which affected more than 6500 people were caused by vegetation on the power lines. Unsecured materials from building sites which were flown and toppled onto the power lines were also a factor.

The areas most affected by the electricity halt were those located in the Rodney district north of Auckland, including Snells Beach, Whangateau, Waiwera, Puhoi and Parakai.

Sandy Hodge, spokeswoman of lines company Vector, said the possibility of power outages during such events is always possible. She said residents should always be ready and prepared with batteries and food, among others.

She likewise said people should be cautious and conscious of trees growing near powerlines.

Vector said the last of 5500 properties near Auckland had power supply restored overnight.

Ex-tropical Cyclone June rammed winds with gusts of up to 90km/h at Auckland Airport and up to 100km/h to Manukau Heads and the Hauraki Gulf.

Sue Keeling told NZ Herald she witnessed how the winds toppled a large tree onto her roof on Tuesday that it almost took down the power lines with it.

"I thought it was a tornado,'' she said. "I wouldn't say it was as loud as an explosion but to me it was very frightening.''

Mike O'Connor, MetService meteorologist, said ex-tropical Cyclone June had already passed the southeast of the country.

North Island will continued to experience rain showers on Wednesday due to a weak low crossing the island today, but "nothing major."

Clouds would continue to cover the top half of the North Island, Mr O'Connor said. Sunshine is forecast to show up at the end of the week.

"The next two or three days will be windy across a number of regions, bringing scorching temperatures to some in the east but perhaps below average for some in the south and west of the nation," Philip Duncan, WeatherWatch weather analyst, said.
