The Machine Count
What's the machine count?
Rewiring Aotearoa’s previous work has identified a massive electrification opportunity for New Zealand, where households, farms and businesses could save thousands per year and the country could save over $10 billion per year if we upgrade our fossil fuel machines to electric equivalents.
We set out to understand these fossil fuel machines: how many there are, how they’re used, and how hard they might be to electrify.
The Machine Count is New Zealand's first complete inventory of all our fossil fuel machines - from cars to tractors to industrial equipment. It’s a free, public dataset showing how many machines burn fossil fuels across the country, what they're used for, and what steps need to be taken to upgrade them to zero-emissions alternatives.

Report highlights
84% of machines are ready to electrify
10% need some effort

Only 6% need further research or cost support
Data spotlight
When we categorise the 10.2 million fossil fuel machines around the country by their “electrifiability”, we find that the majority are both technically feasible to electrify, and readily available in New Zealand. The chart shows that vast majority of machines (84%) can be decarbonised today.
Electrifiability categories

Just electrifying the top priority machines can save a lot of emissions.
The below waterfall chart shows all the energy emissions used across the New Zealand economy. It illustrates how the largest reductions come from a few target machines – namely, cars and commercial vehicles like trucks, utes, and vans. However, the large cumulative impact of the smaller annual savings from the other machine types must not be overlooked – all of the machines in this priority list represent significant, permanent year-on-year emission reduction opportunities that we can not afford to waste.

Sector insights
Residential
The residential sector can be fully electrified now at lower cost and going electric should be the easy default.
Households can slash their power bills, cut emissions, and improve home comfort by switching to electric vehicles, heat pumps, and induction cooktops. For many families, this means saving thousands each year while also doing their bit for the climate.
Better access to finance is required to deal with upfront costs, information should be readily available for all demographics. Once installed, these machines lock in savings for years to come and renters and low-income homes can also benefit.
Agricultural
It's a mixed bag of easy wins and technology challenges on farms.
Farmers can reduce operating costs and emissions by swapping diesel for electric, especially when paired with solar.
The 'lowest-hanging fruits' include mowers, tractors, ATVs/UTVs, trucks, forklifts, and handheld tools like chainsaws and line trimmers and these quieter, cleaner, lower-maintenance machines make life easier. Utes are another major opportunity - but there are limited options currently available.
More advances are needed for machines like high-horsepower tractors, but there’s already plenty that can be electrified today with strong returns.
Businesses & Institutions
The electrification challenges and opportunities are diverse in this sector, but businesses can learn from real-world electrification journeys and must prepare for technology changes.
Many businesses and organisations have similar machines and energy economics as the residential sector, so the savings stack up when they electrify their heating, kitchens, and light vehicles. Real-world case studies show it’s do-able, even for those leasing buildings.
Looking at lifetime costs is crucial during procurement and starting small and building up works well. Going electric now means staying ahead of rising energy costs and customer expectations.
Industrial
Industrial sites face tougher challenges and decarbonisation requires focus at an individual site level, especially for high-temperature processes.
Switching from coal and gas to electricity brings massive emission cuts and long-term security.
Solutions exist for process heat below 100°C (heat pumps) and between 100-300°C (electrode boilers), but technologies for higher temperatures are still developing.
Large energy users like steel, methanol, fertiliser and cement producers need unique decarbonisation pathways requiring both innovation and supportive policies.
How to make it happen
Finance innovation
Underwrite low-interest electrification loans with the Crown balance sheet.
Provide on-power bill finance allowing loan repayment and power bills to be paid together lowering overall costs.
Streamlined approvals for longer term green loans secured against property, because energy bill reductions more than cover repayments.
Process innovation
Launch nationwide awareness campaigns so households can learn about electrification from trusted sources and see the numbers for themselves.
Support community groups and pilots to show homes and businesses what electrification looks like.
Provide training for tradies and sales people who can act as trusted advisors on the benefits of choosing electric and offer technical advice at point of purchase.
Adapt appliance star-rating stickers and vehicle emissions labels to include useful information about cost and emissions saving.
Require transparency of rental property energy costs including current energy bills, electrification status and home quality.
Develop procurement strategies and pilots to improve access to electric machines that are not yet readily available in New Zealand.
Why are we counting the machines?
Our global emissions problem is primarily an energy problem.
Around 73% of global emissions come from energy.
Solving that energy problem in practice is a machine problem.
Underneath all of our energy emissions categories sit fossil fuel machines, from coal power plants to petrol vehicles and gas water heaters. We need to swap those fossil fuel machines for zero emission electrified alternatives.
Conventional thinking has under-appreciated the role of the many "demand-side" machines.
There are millions more machines that sit on the demand side of the energy system, like our cars, trucks, tractors, space heaters and more.
New Zealand's emissions are unique, but the solution to rapid emissions reduction is the same.
Climate change is a cumulative emissions problem, meaning the more we can reduce now the more impact we can have. We don't have electric planes yet, or zero emissions shipping, or zero emission cows... Yet we do have many of the electric machines in homes, businesses, and on farm that can replace fossil fuel machines while delivering more energy productivity and bill savings.
The good news is electric machines are significantly more efficient, and can save on energy bills.
As we've shown in Electric Homes, Investing in Tomorrow, and Electric Farms, electrification can save money and emissions at the same time. The Machine Count project was all about showing how many machines we need to electrify and how viable they are in different areas.
The even better news is that 84% of them are ready to electrify right now.
The Machine Count project showed we have 10 million fossil fuel machines in New Zealand and almost all of them can be electrified right now, with rapid advances making it increasingly viable in other sectors.
