The Government has unveiled its long awaited electric vehicles policy - but what real difference will it make to the uptake of EVs? The government is to investigate bulk purchasing for government and private sector fleets, to make the cars cheaper to import. It's envisioned that those cars will eventually be sold as second-hand vehicles - putting lower priced EVs into the wider market.But there's criticism that a key policy that has boosted EV ownership overseas - tax breaks for buying electric vehicles - is not among the measures included. The Transport and Energy Minister Simon Bridges says other parts of the policy will make a difference to how much EVs cost.
