Rewiring Aotearoa represents everyday New Zealanders in the energy transition and is working to build an electrified future where every Kiwi saves money on energy bills, reduces their carbon emissions and has the resilience to keep their lights on and homes warm.
Our submission:
Thank you for the opportunity to provide feedback on MBIE’s Going For Growth: new procurement rules. We support the role that government procurement can play in benefitting every community across the motu.
We agree that simplifying and streamlining the procurement process is important, and reducing rules is a logical starting point. However, this should not undermine key considerations and past efforts
in ensuring government spending supports long-term positive outcomes.
Given our limited time and resources as an independent non-profit with a small team, we have decided to keep this submission brief. It consists of two sections:
1.0 General context
2.0 Answers to selected consultation questions (specifically Rules 1-5, Rule 7 and Rule 8)
This section provides a general overview of our high level concerns with this plan, in which we aim to support with insights from across our work.
1.1 Growth
Energy productivity of electrification
Electrification shifts fossil fuel-based systems to electric alternatives, significantly improving efficiency and reducing costs across sectors. Electric machines (e.g., EVs, appliances, and heating) convert energy much more efficiently than fossil fuel counterparts - making better use of resources and reducing waste. For example, EVs convert 87-91% of electrical energy into motion, whereas petrol vehicles only convert 16-25%, with the rest lost as heat and vibrations. This efficiency reduces energy consumption, emissions, and operational costs.
One of the underappreciated points about electrification is that while it does involve consuming more electricity, it consumes less overall energy. Fossil fuels need to be burned to create useful energy, but this conversion process is incredibly inefficient. Most of the primary energy is lost as heat during combustion, and even more is lost in distribution. In fact, it is estimated that the global energy system currently only converts about 35% of primary energy into useful energy. Electric alternatives, powered by renewable sources, drastically improve this conversion efficiency.
Electrification not only improves energy efficiency but also optimises material usage. Unlike fossil fuel systems, which are resource-intensive and wasteful throughout their lifecycle, electric systems use materials that are more readily available and highly recyclable. While some electric products have higher manufacturing emissions, these are outweighed by their much lower operational emissions, resulting in a net reduction in lifetime emissions. Moreover, electrification reduces the overall energy and material demands of our system. While building renewable infrastructure does require resources, the impact of fossil fuel systems (through extraction, transportation, consumption, and waste) is far greater. Technologies like rooftop solar and home batteries, for example, provide decentralised, local energy solutions that require less land and materials compared to large-scale power stations, enabling us to meet our energy needs more efficiently and sustainably.
Electrification is about doing more with less. It offers a pathway to a better energy system through greater efficiency, lower impacts, and higher energy productivity. By switching to electric technologies powered by renewable energy, we create a more efficient, resilient, and sustainable energy system – one that reduces waste, lowers costs, and decreases environmental impacts. Electrification describes a journey and not necessarily a single event. It’s a transition that not only makes economic sense but is essential to meeting our climate goals and securing a cleaner, more resilient future for all.
Government procurement can support us to go for growth by increasing productivity of energy, which is a fundamental economic input
As Aotearoa NZ’s economy transitions, it will face both contradictions and growth in various sectors due to the physical impacts from climate change as well as the impacts of future adaptation strategies. The uptake of electrification is not a deadweight cost to the New Zealand economy, it is rather an investment into a more credible pathway to future economic prosperity.
Climate change is fundamentally a cumulative emissions problem. Small annual emission reductions turn into large cumulative savings over time. Furthermore, these small machines in aggregate make up more emissions than the big supply side machines. The faster fossil fuel machines are removed from the economy, the greater the avoided cumulative climate emissions. Understanding which machines are both technically and economically feasible to electrify now provides a roadmap for rapid emissions reduction while generating economic benefits.
1.2 Electric vehicles
We are concerned about the decisions to remove the requirements for government agencies to purchase battery electric or hybrid electric vehicles, though do note that if designed and implemented well Rule 8, Economic benefit to New Zealand, can achieve the same outcome.
Domestic transport accounted for 17.5% of Aotearoa NZ’s total emissions in 2022 and household vehicles represent the largest component of household emissions. This is unsurprising as Aotearoa NZ has one of the highest rates of motor vehicle ownership globally. Despite this, only 1.8% of the total fleet are EVs.
Cars of all varieties are the highest-emission machine type nationwide due to widespread usage.
Emission considerations aside, the costs involved with owning and operating an ICE vehicle have been rising considerably and will continue to do so. And while EVs do offer a cleaner and cheaper alternative (over the long run), their high upfront cost remains a barrier to widespread adoption.
As more electric models become available, they offer significant lifetime cost savings for most drivers, especially when purchased second hand. In terms of operating costs, they are cheaper to run from day one. Therefore, enabling widespread electrification of light vehicles requires swapping fuels for finance. Petrol vehicles lock owners into decades of costly fuel bills. EVs may cost more, but will have significantly lower operating costs. Finance can bridge this gap, with running cost savings used to pay off the upfront cost.
This has led to what is now referred to as ‘dual energy hardship’ - that is the combination of energy hardship and transport hardship. Energy hardship has been defined by the affordability challenges of maintaining a comfortable and healthy home temperature. However, transport-related hardship is becoming an increasingly important issue, especially with rising fuel and vehicle maintenance costs aforementioned. While less visible, transport hardship affects social mobility and limits access to opportunities, particularly for those in rural areas or with lower incomes who rely heavily on their vehicles.
Electrification of transport, through the adoption of EVs, would help address both of these energy and transport hardships. The potential to generate power through consumer energy resources (CER) would reduce household energy costs, while also offering a lower-cost alternative for fueling EVs compared to ICE vehicles. As EV prices decrease and charging infrastructure expands, this transition would alleviate key financial pressures related to both energy and transport, improving access for more people across the country. In tangible terms, transitioning to EVs means we can power our transport on renewable energy instead, and spend that $20 billion (average annual household and business spending on fossil fuels) within our country and communities. Some of that spending will go to local solar generators, including households, some of it to trades to install that solar; most of it is savings for consumers and businesses on their petrol bills, meaning more money for everyone to spend in the local economy, and lower supply chain costs for goods moved across Aotearoa NZ.
Putting the costs and emissions savings potential of EVs aside, making a sizable investment into EVs represents a huge opportunity to strengthen Aotearoa NZ’s energy security and resilience. To this end, and to speak to the recommendation more specifically, this (often overlooked) benefit was recently highlighted in MBIE’s Fuel Security Study (2025). The study (written by Castalia and Envisory) analysed a range of options for enhancing Aotearoa NZ’s energy security – examining potential strategies to diversify and strengthen fuel supply chains, focusing on reducing the country’s reliance on imported fossil fuels and increasing the resilience of the energy system. The study’s findings underscore the importance of accelerating the country’s energy transition. It concluded that investing approximately $130 million annually into accelerating the energy transition of our vehicles would yield approximately twice the positive impact on fuel security compared to reinstating the Marsden Point refinery, which would cost approximately $750 million per year.
Part one - Core values - Rules 1-5
This part is focussed on the values or behaviours expected of agencies and suppliers when conducting all procurement activities. These core values, which include integrity, accountability, transparency and fairness, are critical for creating and maintaining public confidence in how government uses public money. Key new elements are requirements to publish agency procurement policies and clear expectations on acting with integrity and being accountable.
1. Are these the core values that contribute to improved public trust and confidence?
2. Are there other values, requirements or applications that should be added?
The core values included in the consultation document - integrity, accountability, transparency and fairness - we agree, are important and should be included. However, in our opinion, these reflect a relatively short-sighted vision and ignore some key considerations that we believe are much more important in “creating and maintaining public confidence in how the government uses public money”. These are as follows:
Part two - Procurement lifecycle steps - Planning Rules 6-9
Planning is critical to achieving good outcomes. The Rules in this section set out requirements focused on enabling agencies to realise the best possible public value from government contracts. This includes a requirement to undertake appropriate planning for the size, risk and complexity of the procurement, and detail on the elements to be addressed when planning a good procurement. A new Rule requiring agencies to include economic benefits to New Zealand in every procurement replaces the Broader Outcomes Rules. The new Rule enables agencies to consider a wide range of matters that contribute economic benefit to New Zealand. There is also a new requirement to award below threshold procurements to capable New Zealand suppliers.
3. Tell us what you think about these proposed changes?
Rule 7: Estimating the monetary value of a procurement.
While 7(2a) does consider the “total value over the whole of life of all the contract/s (excluding GST) that result from the procurement, including costs associated with disposal of the goods”, we believe that how this is to be interpreted and implemented must be made very clear, and the rule could potentially go further.
Our research has shown that despite the long-term economic advantage of electric alternatives, consumers often make purchasing decisions based on immediate affordability rather than lifetime costs. For example, new gas water heaters continue to be installed because the upfront cost of heat pump alternatives is prohibitive for many households, even though they are cheaper over their lifetime. Similarly, petrol vehicles are purchased when suitable electric options would cost significantly less to run over their lifespan. These purchases lock in emissions and higher bills for years to come.
While much of our research to date has focused on household machines, our forthcoming report The Machine Count: Building an actionable pathway to an electrified zero-emission energy system for Aotearoa New Zealand to be published later in April, includes more information on machines beyond households, including their economics and availability.
We recommend Rule 7 to be strengthened to make it explicitly include assessment of total ownership costs of contracts - i.e. including all significant operational costs. This could be achieved through an addition to 7(2b) of “required inputs for the expected life of the good, such as petrol, diesel or electricity."
The example of EVs is included on the next page. Accounting for energy costs by tenants in new social housing and energy costs for schools for any new schools and refurbishments are very relevant other examples.
Example: EVs vs ICE vehicles
Fossil fuel machines often have a lower upfront capital cost, but a much higher operational cost. For example, an electric car might be $5,000 to $20,000 more than a similar petrol car, yet if that extra upfront cost is divided over the lifetime of the car, then it will often be lower than the refuelling costs of a petrol vehicle. This includes the charging costs of the electric vehicle. These annual running costs are shown in the below graph, followed by energy prices per kwh used and overall lifetime costs of petrol versus electric cars.
Rule 8: Economic benefit to New Zealand
Rule 8: Economic benefit to New Zealand should be strengthened to consider the impact of procurement decisions on the balance of trade, energy resilience and fuel security.
In our Investing in Tomorrow report, we considered the effects of household electrification on the balance of trade by contemplating the impact of more domestically produced energy on Aotearoa NZ’s existing energy mix. For example, the electrification opportunity could save Aotearoa NZ households around $10.7 billion a year by 2040, save 10 million tonnes of emissions annually, and 105 million tonnes cumulatively between 2024 and 2040. This represents a significant opportunity (and consequently significant impacts if overlooked) for our balance of trade. The cumulative procurement decisions of government will have a big impact on this.
There are also significant economic impacts associated with the energy resilience and fuel security benefits that result from the electrification of homes, farms, businesses, and vehicles. The impact (whether positive or negative) of procurement decisions on energy resilience and fuel security should be included in Rule 8’s criteria.
On Nine to Noon, Kathryn Ryan looked at the growing issue of homes with piped or bottled gas facing increasing prices and fewer choices, "as complaints about services doubled in the last year. And it's not just households."

Rewiring Aotearoa CEO Mike Casey joined a group of the country's most effective communicators for a Sustainable Business Network workshop recently. As the story says, "evidence shows that messaging evoking positive emotions is more effective than that focused on the negative." Casey regularly aims to inspire action through optimism and solution-focused storytelling and that's what he urged more businesses to do.
Read moreDownloadRewiring Aotearoa has been blown away by the engagement of everyday New Zealanders in the recent consultation by the Energy Competition Task Force. It asked how consumers should be better rewarded for helping the energy system during peak periods and while we use the term consumer in our submission as it is what the regulators use, we couldn’t agree with one submission: “What is required is not the empowering of consumers. It is the redefining of consumers as participants in the energy system.”

Read moreDownloadOverall, Rewiring Aotearoa welcomes the objectives of this package of proposals. from the Energy Competition Task Force. We view the package as a critical step in improving energy system outcomes for all consumers. We consider retailers paying consumers fairly as a critical step, and we are mostly satisfied with the Task Force’s approach to this (initiative 2C) and think it will create better outcomes for New Zealand consumers and the energy system as a whole. In contrast, the Task Force’s preferred option around how distributors are required to reward peak input from consumers (initiative 2A) will not in our view meet the Task Force’s (or the Electricity Authority’s) stated objectives.

Read moreDownloadA Federated Farmers’ survey of 1,000 farmers showed that 70% of respondents would consider installing solar panels and the enthusiasm was evenly spread across different age groups, genders and farm types. The economic drivers are clear and farms can significantly reduce their electricity costs with solar (and, if they invest in electric machines, their diesel costs), but there are plenty of unnecessary barriers stopping them from saving money, reducing emissions and playing a role in the energy system. We’ve pulled together a document that talks about the massive opportunity rural electrification offers, outlines the issues farmers are facing and what the decision makers need to do to make it easier.

Read moreDownloadThere’s been an understandable focus on the price of electricity recently, with fears we may be in for a repeat of the wholesale debacle of 2024 as our hydro lake levels remain low. The Energy Competition Taskforce made another announcement about levelling the playing field for independent retailers and removing preferential pricing for the gentailers’ retail arms. Just like the previous announcement that talked about moves to level the playing field for customers with solar and batteries, this is another positive step towards a fairer system, but it’s not guaranteed to bring electricity prices down, as Mike Casey told Andrew Dickens on Newstalk ZB.
As the focus remains on rising electricity costs in New Zealand, solar and storage continues to drop in price and is set to become the cheapest source of energy around the world in the next few years; an Auckland man's quest to create the world's first electric helicopter; the efficiency of electric flight and the pitfalls of predictions; an electric road in Sweden that could wirelessly charge EVs; solid state batteries take to the streets and look set to increase range; and why going electric was better than offsetting because it led to actual emissions reductions for WoolWorks and Sawmill.
Read moreDownloadRewiring Aotearoa CEO Mike Casey writes in Newsroom (paywall) that the low hydro lake levels are putting us at risk of another energy crunch in 2025, but more solar on our homes, farms and businesses would help bolster our energy security. As he says: "Solar is an energy source that is proven to perform better in dry years, ranks as the cheapest form of energy ever developed by humans and can help bring the cost of electricity down for everyone. When the leaves start dropping next year, I hope Min. Watts isn’t quite as concerned about lake levels or long-term forecasts because he can bask in the sunshine and know that he has helped more New Zealand homes, farms and businesses generate cheap electricity from the big nuclear fusion reactor in the sky. The future is bright."

Read moreDownloadRNZ's Kathryn Ryan talked to Rewiring Aotearoa CEO Mike Casey and Electricity Networks Aotearoa's Tracey Kai about the changes proposed by the Energy Competition Taskforce and how they will improve the already impressive return on investment for solar and batteries. As Casey said, the most important thing to remember is that the biggest benefits to households come from using solar as it is the cheapest form of delivered electricity available to New Zealand homes and those with electric machines and cars can save thousands each year on their energy bills. Exporting excess energy is generally a cherry on top and the proposed changes to reward peak export might only represent a small increase for households, but they may be significant for farmers or businesses with more space. More solar and batteries also helps to bring down the cost for everyone on the network, reduces the need for expensive pole and wire upgrades, which are paid for on customers' bills and can also help create more security of supply by keeping water in the dams.
A love letter to electrification this week as a kea soars high on solar, more electric buses for Auckland (and more Rivian vans for businesses), longer lasting EV batteries, more solar on smart schools, an open letter to the Australian Government asking for 'Real Zero' not net zero, and the world's first electric snowbike.
Read moreDownloadAs Rewiring Aotearoa’s Electric Homes research has shown, New Zealand has already reached the electrification tipping point, so going electric and running your home and car with a combination of grid electricity and rooftop solar and batteries is already a good economic decision for most homes (and likely the best thing they can do to reduce emissions). But, as Newsroom's Marc Daalder writes about the Energy Competition Taskforce proposals (paywalled), "proposed changes to the electricity market could see Kiwis paid more for the solar power they export to the grid, and less when drawing from the grid at off-peak times".
Read moreDownload"I firmly believe electricity is the next crop for farmers in New Zealand, and the more farmers that get involved in this, the better the returns for farmers are going to be ... My big dream is that farmers start powering New Zealand. That would be really cool." Seven Sharp ventured to Cromwell recently and Rachel Parkin put together a beautiful story about the all-electric Forest Lodge Orchard. The team has proven that it's possible to grow cherries without burning any diesel on the farm - 'not a single drop,' as manager Euan White says - and that farmers can play a role in the energy system by generating, using, storing and exporting their own electricity. At the moment, many homes, farms and businesses are reliant on expensive molecules sent to us from the other side of the world. Fossil fuels have taken us a long way, but there is a better and cheaper option: locally-produced electrons. That's good for businesses, and good for the country as a whole. Watch the show on TVNZ+ (skip to 4 mins).
Fully Charged, which has a large global reach and claims to be the world's number one home energy and electric vehicle channel, came to visit Mike Casey at the all-electric Forest Lodge recently. As host Robert Llewellyn (who Red Dwarf fans may recognise) says: "I think this is a shining example of what can be done today and what should be be done, particularly for countries like New Zealand that have to import their fossil fuels from a long, long way away".
Read moreDownloadRNZ's Susan Edmunds reports on the Energy Competition Taskforce proposals and says the changes "should lead to New Zealanders with solar power systems on their houses get more of a return for any power they put back into the system". As Electricity Authority chair Anna Kominik says: "New Zealand's electricity market currently relies on a few big generators to supply electricity at select locations and transmit it to households and businesses across the country. But as uptake of solar and battery systems continues to increase, more consumers will be able to contribute to our electricity system. And as smart electronics and vehicles become more ubiquitous, consumers will also be able to more actively manage their own energy use and costs. We're proposing three changes to help support this consumer empowerment and decentralisation of our energy system. Over time, this will increase community resilience and lower power costs for everyone," she said.
Read moreDownloadHomeowners with solar panels and batteries installed could be paid more to sell electricity back to the grid, reports TVNZ's Jessica Roden following the release of the Energy Competition Taskforce proposals. As Nelson solar installer Jon Pirie says in the piece, perfectly illustrating the 'neighbourhood effect', "year over year, people are more interested. They see the power bills going down and next thing the neighbours have got solar." Mike Casey also appears in the story saying anything we can do to incentivise customers to install their own generation and storage will help create the cheapest energy system.
Rewiring Aotearoa's response to the Energy Competition Taskforce: a pat on the back for recognising the shift and focusing on the role customers are playing - and will play - in the energy system, but just a light pat because more could be done to ensure the proposals are followed through on.

Why our electric future - from e-bikes to e-boats - looks both fun and functional, why swapping fuel for finance is crucial for homeowners (and access to capital is crucial for businesses like Chargenet that are helping to speed up the transition), how renewable energy projects are helping developing countries and low-income communities, and an ad from 1929 that reminds us of something.
Read moreDownloadStuff's Kylie Klein Nixon showcases the many benefits of Carl Hamlin's electric new build, which includes a hot water heat pump and solar panels. As the story says: "Water heating comprises about 1/3 of a household’s energy use, [EECA's Gareth] Gretton says. Hot water systems have a 15-year life expectancy, and 46% of hot water systems in New Zealand are over 10 years old. When we do replace old hot water systems, there is a tendency to replace like-for-like." Gas is the most expensive, hot water heat pumps have the lowest running costs and you're likely to make the most savings by electrifying your vehicle. If you want to save cash and slash emissions, your next purchasing decision should be electric.
Read moreDownloadThe most important energy cost is not what a corporation pays to produce or generate it, but what a consumer pays to buy it. That’s why Mike Casey argues the delivered cost of rooftop solar and batteries – and the other benefits these technologies provide to the system – need to be factored in when making investment decisions.

Read moreDownloadThe Post's Alka Prasad has gone deep into how farmers are electrifying their operations, installing solar and batteries to alleviate concerns about dry years, and reducing their energy costs. As Maniototo farmer and owner of Solayer Becks Smith says in the story: "It's not an either-or situation from hydro-generated electricity to solar-generated electricity. It's about having a renewable electricity grid and shifting as far from fossil-fuel energy as we can,” she says. “For business resilience, the energy you can generate and use yourself is the cheapest energy you'll ever get." Rewiring Aotearoa CEO and electric orchardist Mike Casey says "farmers could have a huge positive influence on New Zealand's electricity system by generating power themselves and putting it into the grid for everybody else to be able to heat their homes, heat their water and charge their electric vehicles". "We can treat our hydropower scheme more like a battery which could power our homes and businesses at night time and solar can do a lot of the grunt work during the day,” he adds.
