Auckland Transport has added 20 electric vehicles to its fleet at a cost of about $50,000 each - about twice the price of the petrol cars they are replacing.
Mayor Phil Goff says the initial cost is more expensive but a business case has found the savings in petrol, maintenance, higher resale price and replacing 30 petrol cars with 20 electric cars make it economic.
Goff, whose mayoral vehicle is an electric Hyundai Ioniq, says it is critical that the council and Government show leadership by progressively converting their car fleets to electric to meet the country's reduced carbon-emission targets.
The purchase of 20 Hyundai Ioniq electric cars for less than $50,000 each is the largest purchase of electric vehicles in the public sector.
The cars have a retail value of $59,900 each, much more than the price of the Toyota Yaris and Toyota Corollas they are replacing, which respectively sell from $21,990 and $31,990.
