New figures show more people are buying electric vehicles.
More than 3000 are now registered in New Zealand.
The government hopes to double its fleet of electric vehicles annually, and achieved this last year with 1513 registrations.
This was well ahead of Australia's figure of 220 EV registered there last year.
However statistics show electric car penetration was still just scratching the surface.
NZTA figures state there were almost 3.2 million passenger cars and vans registered in total, as of last December.
