"There's hardly a minister here that didn't take the view that over time they are the future."
However, New Zealand's small market meant there was a limited range of vehicles available - eight.
Prices range from under $20,000 for a second-hand Nissan Leaf to $278,000 for a top-of-the-line BMW sports model. "New Zealand is a small market and it's difficult to get manufacturers to supply their EVs in the first place," said Bridges.
"In a preliminary way I'm talking to the manufacturers to see what we can do around the margins to bring their cars."
The Ministry of Transport is working on a package to encourage faster uptake but this is unlikely to involve financial incentives.
"It will be relatively modest, it's not going to involve big subsidies or tax breaks. If we were to throw a whole lot of taxpayer money at this it would increase the attractiveness but I don't think that would be a prudent use of public money."
Bridges said a network of charging stations was already being built by the private sector but there was a possibility the Government could help with infrastructure.
He said there was disinformation about the range of vehicles - which can now stretch over 300km - and an education campaign is likely to be part of the package.
In New Zealand BMW Group New Zealand product and market planner Paul Sherley said his firm has sold 20 i3 plug-in cars for $83,500 in the first four months of the year, mostly in Auckland.
It hopes to sell 12 of the $278,000 i8 by the end of the year.
BMW doesn't expect a rapid uptake of the vehicles but Sherley said ways to speed that up would be dropping GST on them, and parking and toll road discounts.
