Rewiring Aotearoa’s Machine Count report showed that upgrading 6 million of the most "electrifiable" fossil fuel machines — things like cars, heaters, lawnmowers, road bikes, ovens and stoves — would save the country about $8 million every day, or $3.7 billion each year.
It would also slash 7.5 million tonnes of carbon emissions each year, almost six times the total emissions from domestic aviation in 2023.
Another 10% of the total — about 1 million trucks, utes, vans, buses and smaller tractors — could be electrified if more effort was made to bring electric options to New Zealand, while just 6% of the machines — primarily those in heavy industry — require more research and development or subsidies for them to be cost-effective.
EECA research shows 36% of New Zealand household non-green appliances are more than a decade old, so many will be replaced in the coming years.
