Mercury Energy has developed a special fuel package for individuals and businesses who purchase the Nissan Leaf, a mass-produced, zero-emission electric car.
According to Mercury general manager James Munro, commuting from Takapuna to the Auckland CBD using the vehicle programme could cost as little as $20 a month in electricity.
"This compares to the $120 (approximately) that you would pay if you drove an equivalent-sized, petrol-fuelled car."
Munro said Mercury would fit special technology into the homes of Leaf buyers that would allow them to measure the power used to charge the car, separate from general household consumption.
Insurance company Sovereign has taken up the offer, receiving 30 percent off off-peak electricity recharge costs.
Sovereign will use the Leaf as a company pool car and has installed a charging station at its Smales Farm head office on Auckland's North Shore, and says it is the first company in New Zealand to buy the world's first mass-produced, fully electric vehicle.
The Nissan Leaf won both the 2011 World Car of the Year at the New York International Auto Show and the 2011 European Car of the Year.
Nissan New Zealand managing director John Manley said the car boasted a superior recyclability rate.
"Not only are the vehicles comprised of a high percentage of recycled plastics, fabrics and other materials, but at the end of their life span, 99 percent of materials will again be recycled to create new Nissan Leaf vehicles or other plastic products."
