Mighty River Power CEO Fraser Whineray said the charging stations would allow motorists to fuel-up free with 'home-grown' renewable electricity - a cheaper and cleaner alternative to imported fossil fuel.
"There is a compelling proposition for all of us and for New Zealand in supporting the uptake of renewable electricity as a transport fuel. It's made right here, costs less than 30 cents per litre, and takes about 2 tonnes of carbon out of the environment for every EV on the road every year."
Mr Whineray said Auckland had the highest rate of EV ownership, and public charging stations were important for consumers to be confident they can fuel-up when they need to.
"Working with organisations like Auckland Transport (AT) to install chargers in prominent parking areas is a great way to show the momentum and positive change beginning in New Zealand's transport fuel mix, making the city's air cleaner.
The charging stations are 7kW chargers, suitable for any plug-in vehicle to top up or fully charge. They are located on the ground level of the Downtown Carpark near the Customs Street exit.
