Trees like this one have been playing havoc with Auckland's powerlines. Pictured in Three Kings, Auckland.

Bad weather has cut power to homes across Auckland thanks to stray vegetation and sliding cars.

On Friday afternoon a car accident at School Rd in Waimauku was causing power outages in West Auckland around 3pm.

Eye witnesses said one car was on its side and passersby were assisting until emergency services arrived.

PETER MEECHAM / FAIRFAX NZ Wet weather has cut power to central Auckland residents.

Police couldn't confirm whether lines were down, but residents on Constable and Taiapa Valley roads reported power outages following the smash.

Meanwhile emergency services were forced to close a road in the Counties Manukau area of Kingseat, after a car crashed into a powerpole.

Nobody was injured in the collision but Vector was working to ensure the safety of the lines before reopening Linwood Rd.

Earlier in the day power was cut to more than 1500 residents in areas around Mt Eden, Three Kings, and Epsom in central Auckland, after sodden branches fell on lines.

Vector crews were working to restore the outage on Friday afternoon and by 2.30pm the number of homes without power was 180.

Vector also said 252 homes around Titirangi in West Auckland were also affected, but power had since been restored.

The cuts were due to feeder faults thanks to wet weather, rather than wind.

Fire Service northern communications shift manager Megan Ruru said fire crew had responded to multiple incidents of trees across power lines.
