Rewiring Aotearoa is working to speed up the transition to an ‘electrified’ future, with work showing that upgrading fossil fuel machines to electric equivalents can save New Zealanders money on their energy bills, decrease emissions and give communities the resilience to keep their lights on and homes warm. ASB and Rewiring Aotearoa partnered up in 2023 and conducted research to identify barriers to households and farms going electric, undertook thorough literature review and considered potential finance solutions to address these barriers. This report covers some of the high-level themes uncovered during that process.

There is a need for electrification
People care about climate change and want to do more about it. Moreover, a number of households are struggling with the costs of the traditional electricity system. Many people report feeling cold in their homes as a direct result of trying to save money. Alongside cost of living savings, there is a need for electrification in order to reduce emissions, improve energy resilience and security, and mitigate hardship.
The electrification system is complex and confusing
The electrification system is not user-friendly. It is difficult to understand and interact with, which makes it difficult for households to electrify. Many people find it hard to understand and navigate the many different parts of the system required to electrify (e.g. installation, finance, insurance, regulation).
There is latent demand for electrification
Many people have strong intentions to electrify but perceive significant barriers to doing so (Frustrated Enthusiasts). At the other end of the spectrum, there are people that do not perceive any barriers to electrification, but have no intention to do so (Reluctant Movers). Combined, these groups present a significant amount of latent demand.
This demand can be activated
The most significant barriers to electrification are poor information and access to finance. There is currently a lack of diversity and sufficiency in electrification financial offerings. There are also particular barriers for renter and coowners (e.g. those of community houses and Māori land) to access finance.
Overcoming Barriers
Barriers can be addressed by providing new information, new financing options, and other support.
More specifically:
Information.
Access to reliable information is a critical factor in decision-making. Making data open, accessible, and intelligible can help people move more quickly to economically beneficial investments, and also to reduce the perceived risk of adopting new and unfamiliar technologies. For example, for Frustrated Enthusiasts, good information about the electrification system addresses a considerable barrier. For Reluctant Movers, the most likely leverage point is information that helps them understand how electrification is aligned with their interests or values.
Access to finance.
Although electrification is getting cheaper, solar, batteries, and electric vehicles remain a significant upfront capital investment (equivalent to paying multiple years worth of electricity and fuel costs upfront). Providing better access to finance through financial innovation to all types of households, including Māori, co-owners and renters, is a clear way to address this.
Action should be taken now
Given the country is at an electrification tipping point, there is an opportunity for banking sector leadership in electrification finance. Although there are some wider system constraints to sustainable finance, there is enough internal flexibility for banks to still realise this leadership opportunity.
Action should be innovative
As this is an emerging area of finance, there is opportunity to innovate and experiment. This approach can help achieve longevity and scalability. In particular, focusing on long-term opportunities as well as risks, and taking a more holistic approach to value that includes non-monetary risks and opportunities.
Action should be ambitious
The electrification system is still at an early stage of development and does not make it easy for people to electrify. There is currently no pace or scale to its development. This is partly because of a lack of money but it is also due to a lack of cohesion between its many parts (e.g. consumers, trades, smart energy providers, government). As such, there is opportunity for systemic change that brings about a cohesive and user-friendly electrification system.
Partnership is important, particularly with government
Effective engagement with government is a key part of system change. There are limits to what private finance can do within the constraints of capital requirements and fiduciary responsibilities. Consequently, a market-led transition risks improving access to technology and finance for well-off households, but not for the low-income households that stand to benefit most. Government needs to take a proactive role in electrification for those parts of society where the social investment benefits, as well as the risks of insolvency, are greatest.
International Research
Internationally, efforts to decarbonise households have focused on carbon markets, taxes, energy efficiency standards, and retrofitting insulation. Despite the increasing popularity of green mortgages and loans globally, green housing finance remains nascent. Aotearoa New Zealand could benefit from pilot projects and studies exploring diverse finance options for electrification. The motivation for green home upgrades appears driven by both environmental concerns and cost savings. Therefore, accessible finance options that facilitate household electrification, reduce emissions, and lower living costs present an opportunity to address these dual concerns. Access to finance is a significant barrier to household electrification globally, primarily due to high upfront costs. Research highlights that inequities exist in accessing such finance.
Other key barriers are information gaps and limitations for renters. The structure of the banking system plays a crucial role in fostering green economic transitions. Banks offering environmentally sustainable products may gain a competitive edge over others. In internationally comparable personal banking sectors, competition fosters financial innovation, which is essential for advancing green finance. In Aotearoa New Zealand, where banks currently offer similar green loans for home improvements and electrification, there is large potential for market leadership and differentiation.
Enabling Environment
A variety of actors can contribute to the enabling environment for home electrification, including business and civil society groups. However, the OECD notes [1] that “the public sector has a key role to play... [in] creating an enabling environment. A well-designed regulatory framework, information on climate risk and pricing externalities, and better aligned policies could help drive adequate investment” into climate-aligned projects and activities.
Further, our research shows that Government responsibility for electrification and energy resilience is seen as key. There is strong support for policy and market settings that support consumer-owned energy assets. Consequently, the recommendations below are tilted toward levers that governments have unique capacity to influence, through their regulatory powers and capacity to shape and steer markets.
Other Supporting Measures
General information on the benefits of electrification, as well as information-based tools, plays an important role. However, peer effects – that is, the influence of decisions, actions, and beliefs of an individual’s peers – are also strongly influential.
Electrifying households involves a number of options, decisions, and parties. It takes a strongly committed household to pursue electrification on its own, and requires a significant investment of time, energy, and resources. Partnerships can play a critical role. Internationally, and even domestically, there are examples of successful partnerships with the likes of installers, one-stop-electrification shops, utilities, communities and government that emerged in order to reduce the number of parties and decision points that a household needs to directly interact with. In turn, this reduces transaction costs and increases uptake.
There is latent demand for farm electrification
There is a significant amount of latent demand for farm electrification. Our research found two thirds (66%) of respondents fall within this category. This is higher than in research relating to residential respondents, which found latent demand of 48%.
Barriers to electrification can be overcome
The most significant barrier to electrification is the high upfront capital investment required for electric machinery, solar panels and batteries. This barrier includes people lacking access to knowledge about available finance, and attitudes towards debt.
Farm electrification has multiple, overlapping benefits
Many on-farm machines are already electric, including milking sheds, refrigeration, and a majority of water pumps. However, by self-generating electricity from solar panels and other sources, and then electrifying the remaining farm machines, there are multiple benefits. These include reduced emissions, lower energy costs, enhanced profitability, decreased noise levels, and increased energy resilience and security. Additionally, farm productivity can be improved by the adoption of new agricultural technologies, such as automated machinery and precision agriculture technology, which are often electric powered. These benefits are a potential source of strong rural support for electrification.
Sustainability-related trends are prioritising electrification for emissions reductions, but also shaping the development of new agricultural technologies
Electrification is an attractive option for farmers who are under pressure from markets to reduce the emissions intensity of their products. Moreover, these sustainability trends are also influencing the development of new agricultural technologies that enable precision agriculture and on-farm automation, much of which is powered by electricity. Consequently, there is an opportunity to combine farm productivity and efficiency by adopting new technologies, and generating one’s own electricity to deliver the cheapest source of energy.
On farm solar generation has significant potential for installed capacity
Solar generation from available roof and ground space would generate hundreds of megawatts of power per year per farm. It would also generate savings and export revenue of approximately $300k - over $1m across the 30 year lifetime of the panels (the median export revenue based on survey results was $615k for 500 m2 of roof space, and $308k for 250 m2 of ground space). The likely savings and export revenue more than makes up for the upfront cost, which has a median of $221k for rooftop solar and $111k for ground solar. Access to finance will be key to unlocking these savings.
Farm systems vary significantly, but solar and batteries are a common opportunity
Farm systems vary significantly – from dairying, to sheep and beef farming, horticulture, and viticulture. Consequently, there is significant diversity among the machines that these farms depend upon. If there is one common opportunity, however, it is solar and battery systems. This enables a resilient and flexible supply of low-cost electricity into the future, and unlocks the maximum value from the electrification of end-uses. Even if it is challenging to cater to the diverse electrification needs of farms, solar and battery systems are the common opportunity.
Role of Finance
Rural lending, cooperatives, and agribusiness finance have long been a cornerstone of rural finance architecture in Aotearoa New Zealand. Agricultural lending makes up 11% of aggregate bank lending in this country. However, our research shows that there is a gap in targeted financial mechanisms for farm electrification, and better access to finance plays a key role in addressing barriers to rural electrification uptake.
Our research identified the high upfront capital investment required for electric machinery and solar panels as a key barrier to farm electrification. We found many examples of public finance providing for electrification in the international literature, but fewer of these focus on farm electrification. In private finance, we found some lending for electrification but fewer for farm electrification. Further, we found that farms have varied and specific contexts, such as seasonal machinery usage and specific machinery needs. Financial instruments would be most effective if they specifically targeted these unique needs in order to maximise their utility to farmers.
Our research suggests that private finance cannot be solely relied upon for such transitions and that combined (public and private) finance can better leverage farm electrification. In the broader system, we identified the opportunity for greater policy direction and ambition from the government to crowd in private investment towards farm electrification. There are also opportunities for private finance to lead the way on financial innovation for rural electrification, including through innovations such as on-bill financing, contingent debt, and green bonds.
Other Supporting Measures
There are a number of supporting measures that could assist the energy transition to renewable energy in farms through finance products. These are summarised in this table:
Solar smashes a few records and helps the world get off gas and coal; homes, not power plants, are the key to lower power prices; 24 new bus chargers are installed in one day in Auckland; DARPA makes some very special popcorn by beaming energy wirelessly for 8km; and an astronomer discovers an addictive new star gazing app.
Read moreDownloadRewiring Aotearoa's submission highlights that successful digitalisation should allow customers to maximise benefits from their provision of demand flexibility and solar and battery exports, without third parties (aggregators or VPPs) routinely taking a cut of the value. Retail offerings that include time of use prices and fair export tariffs will be key enablers of successful digitalisation of the electricity system. Customers need a fair deal through their electricity prices and export tariffs. This means the customers need to have the option to choose from a range of retail tariffs that include time of use prices, fair export tariffs (that reflect the value in the wholesale market) and symmetrical export tariffs from distributors.

This is pertinent to Rewiring’s work, because one of our core aims is to help reduce energy bills for customers - NZ’s households, farms, and businesses. Significant changes are needed to fix the status quo, and we are concerned that the Bill may inadvertently bake in the existing rules governing the sector.

These guidelines can provide a consolidated and trusted source of information to help households navigate the process of choosing and installing solar PV and batteries. There is some messaging and information in the PAS that we think needs to be changed or added to provide households with the best advice to support them to maximise benefits from solar PV and batteries. This includes removing the focus on pay back periods and informing households about cost savings from day one from solar PV and batteries financed over the life of the system. Households also need information about the potential risks of some existing lease to own sales models which provide little real benefit to households with the bulk of the savings captured in suppliers profits.

Rewiring Aotearoa's Mike Casey said the changes to voltage limit would mean more generation, "which is exactly what New Zealand needs… for households in Australia, the average size for solar systems is about 10kWh. In New Zealand it's 5 or 6kWh because solar installations are being built to the size people are allowed to export. This allows for higher levels of solar panels to be on homes. It makes larger systems more economical. When you finance solar panels on your mortgage it probably costs you 13c per kWh - there are many retailers out there buying power off you at more than 13 per kWh. So every piece of power that you don't use in your home that goes back to the grid is actually still in the economic best interest of the household."

In our policy manifesto, the number one thing we're hoping to get across the line is a scheme that gives everyone access to low-interest long-term loans for electrification upgrades. We believe the best way to do that is through the proposed Ratepayer Assistance Scheme and The Post's Harriet Laughton has looked at that scheme and what that might mean. Several large councils are already backing it, others are being asked to support it, and Simon 'MegaWatts' Watts has also indicated he's supportive. That could mean New Zealanders would be able to get cheaper finance to install electric appliances like heat pumps for space and hot water and solar and battery systems - and they would be saving money on their energy bills from day one.

The business community is really aligned under the carbon zero 2030 targets set by council, the council is really aligned, and there are a lot of very active community members in this space who are super excited. Queenstown pays some of the highest energy prices in New Zealand, so it's a really good place to start and there are also problems with resilience from the Alpine Fault so it's a good idea to have Queenstown generating and storing energy itself and having machines that can use that energy." Listen from 11.20.
Crux talks to Mike Casey about the launch of Rewiring Aotearoa's ambitious new Queenstown Electrification Accelerator project. "The vision is big. To make Queenstown the global capital of total electrification - buses, cars, hotels, our airport, houses - and yes, even gondolas. For the region to become the world’s most electrified destination."
Rural solar already made sense in most cases, but ASB has made it even more appealing with the launch of what could be seen as the farm equivalent of a green loan: 0% interest for five years for farm installs worth up to $150,000.

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. Government procurement can support us to go for growth by increasing productivity of energy, which is a fundamental economic input

That's the message from the team behind a cherry orchard in Central Otago, which started swapping diesel for electric on their 6 hectare site and went fully electric in 2021. Now they've put their electric tractor to a real test, going for a hot lap around Highland Motorsport Park in Cromwell." Electric Cherries' Mike Casey and Euan White cross live on Breakfast to discuss the record attempts, the Monarch tractor and the broader ambitions (head to 2.10 to hear the interview). Looking forward to having Liam Lawson take it for a spin soon.

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 moreDownloadNew Zealand farmers are well accustomed to turning sunlight into food and fibre. Now, as Mike Casey writes in The Australian Farmer, there’s an opportunity to turn that sunlight into something else that will benefit New Zealand and the rural sector: renewable electricity.
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 moreDownloadRewiring Aotearoa is working to speed up the transition to an ‘electrified’ future, with work showing that upgrading fossil fuel machines to electric equivalents can save New Zealanders money on their energy bills, decrease emissions and give communities the resilience to keep their lights on and homes warm. ASB and Rewiring Aotearoa partnered up in 2023 and conducted research to identify barriers to households and farms going electric, undertook thorough literature review and considered potential finance solutions to address these barriers. This report covers some of the high-level themes uncovered during that process.
Read moreDownloadThis consultation is a key input into unlocking some benefits that will speed up the adoption of solar and batteries, increase system sizes, and help create the lowest possible cost energy system for Aotearoa New Zealand. We believe that many of the proposals are positive steps and have recognised the technological and economic shifts that are happening in energy, but there is still some bias against investments made by homes and farms towards investments made by networks and energy companies. Whether you've got five minutes or a few hours, your submission can have a real impact on the final decisions and ensure the playing field is made level. Here's how to make your voice heard.

RNZ's Eloise Gibson outlined how Clarus removed an ad that said 'renewable gas was now flowing' following complaints to the Advertising Standards Authority about misleading consumers. The issue was that the renewable gas was being blended with fossil gas and only made up a small fraction of the total. The bigger issue is that it's even more expensive than fossil gas (which is already more expensive than electric equivalents) and there's not enough of it to meet demand.
