"I applaud the NZ Government for proposing a clean car standard [but] you could say it is about time, as New Zealand is one of only three OECD countries without any kind of vehicle fuel efficiency standard," she said.
"This plan is essential to push for cleaner cars and to ensure a greater EV supply. It also sends a message to car manufacturers that NZ is no dumping ground for outdated technology."
The plan proposes a target of 105g of CO2 per kilometre for cars imported to the country in 2025.
She said it was important to set a target and this could now be reached with the right measures.
The average in NZ last year was 180g/km. The average emissions from new cars sold in Norway in 2018 was 71 g/km, managed because of EVs.
So far this year, 45 per cent of new car sales in Norway were battery electric vehicles and the country has almost 140,000 battery vehicles, out of a total of 2.8 million passenger cars.
New Zealand has about 12,000 EVs — mainly hybrids — in a light vehicle fleet of more than 3.5 million. However, the rate of growth in battery vehicles is accelerating.
In Norway, the most popular passenger cars this year are all fully electric — Tesla's Model 3, the eGolf, BMW i3 and Nissan Leaf.
Norway has a range of incentives including higher taxes on the purchase of higher emitting vehicles. It has a value added tax of 25 per cent on petrol vehicles, while while battery vehicles are exempt.
