Prime Minister Jacinda Ardern says the Government considered exemptions for farmers and tradies for its feebate scheme - but ultimately decided against them because they would be "hard to operationalise".
The scheme, announced on Monday, is designed to increase the number of electric and plug-in hybrid vehicles in the country, and aims to reduce greenhouse gas emissions in line with advice from the Climate Change Commission.
Under the scheme drivers who buy new cars from July 1 will be able to get taxpayer-funded rebates of almost $8700 for a new electric or plug-in hybrid car, and about $3500 for used cars.
These would be funded by fees based on emissions levels applied to new petrol cars up to $5875, and up to $2875 for imported used cars.
The fees will be applied from January next year and could add almost $3000 to the cost of the top two imports – the Ford Ranger and the Toyota Hilux.
