A series of public events to celebrate Earth Hour are being held around New Zealand tonight.

The global event encourages people to turn lights and electrical appliances off at 8.30PM as a way to raise awareness about environmental sustainability.

Earth Hour coordinator for the World Wildlife Fund, Rosa Argent, says in central Auckland a group of skaters, BMX riders and cyclists will take to the streets to raise awareness about litter and urban waste.

"We've also got, down in Selwyn, Canterbury, they've been having a week of Earth Hour events culminating in a barn dance tonight.


"And in Tauranga, the local community are getting together around a big dessert night."

Public icons such as the Auckland Sky Tower, the Parliament buildings and even Paeroa's L&P bottle will commemorate Earth Hour by going dark.
