News & Updates

Energy has been a huge issue for the New Zealand economy in recent years, and a growing concern for everyday New Zealanders, but there wasn’t a huge focus on it in the Budget. While we see this as a missed opportunity, Minister Simon Watts, Minister Shane Jones and their Cabinet colleagues have an opportunity to make up for it before next year’s election and, next week, Rewiring Aotearoa will show them how with the launch of our policy manifesto.

The IEA's EV outlook shows another big bump in global sales; research shows what to focus on if you want to promote EVs (even to the sceptics); New Zealand solar uptake has spiked but is still a long way behind other markets; the price of renewables continues to fall faster than governments predict; the company improving induction (and trying to sneak batteries into homes in appliances); and the companies recycling batteries to get the minerals we need for the electric transition (at lower cost than 'virgin' mining).
Read more'You're asking me to use more electricity even though it's getting more expensive?' As you may have gathered, we're pro-electron here at Rewiring, but it's hard to get past this perception and, over the past couple of years, stories about cost increases and supply shortages have been in the news a lot. Not surprisingly, that's affecting the attitudes of New Zealanders and a recent survey from Octopus Energy showed that 85% of respondents were just as worried or more worried about the rising price of electricity this year and 70% thought the Government wasn’t doing enough to help address these costs.

Newsroom's Marc Daalder reports on the mysterious disappearing home solar incentives proposed by climate change minister Simon Watts to then energy minister Simeon Brown, while Mike Casey explains why solar subsidies aren't necessarily needed but would help drive demand among consumers and bolster our hydro storage.

The first complete inventory of all the fossil fuel machines in New Zealand has found there are over 10 million of them and 84% could be feasibly replaced with electric machines that are available in the country today.

It's been a big week for Rewiring Aotearoa with the launch of the Machine Count and there's plenty of electric momentum elsewhere, too, as Tasmanian company Incat launches the world's biggest electric boat, Old Blighty backs Old Brighty with a policy to put solar on all new builds, a Swiss company's mission to add solar panels to the country's railway network and a helpful (satirical) app that allows you to 'meditate through the meltdown' and 'push down the climate anxiety'.
Read moreTirau chicken farmer Jeff Collings talked to us for our Machine Count report and we thought his story deserved a bit more attention, so it was great to hear him interviewed by Jesse Mulligan on RNZ.

"84% of the country’s machines had mainstream electric alternatives that were cost-competitive or cheaper over their lifetimes, and already available for purchase in New Zealand. The included space heaters, water heaters and small and medium cars." EECA’s Megan Hurnard said: “Replacing outdated machines with the same inefficient models risks locking in higher running costs, poor performance, and greater exposure to fuel price volatility."
Read moreWhether you're in it for the economics or the emissions, upgrading to electric machines works - and it works particularly well in New Zealand, where we have lots of relatively cheap electricity and very expensive fossil fuels. Rewiring Aotearoa believes this transition is inevitable, primarily because it's crazy to use machines that cost more to do the same job and, increasingly, that's the case with fossil fuelled machines. Farmers and businesses are starting to grasp this, but Mike Hosking has a wee way to go. He discussed the Machine Count report on his Breakfast show. So do you agree with Mike Hosking ("Pointless. Waste of time. Nothing's changed) or Mike Casey ("We can solve climate and save everyone money")? Listen to Hosking's take on the Machine Count from 59.40.

The Post's Alka Prasad reports on Rewiring Aotearoa's Machine Count project, which found that "Aotearoa has over 10 million fossil fuel machines - those powered by petrol, diesel, gas and other fuels - that could switch to renewable energy and save the country 7.5 million tonnes of carbon emissions each year. But researchers quantifying this task found electrifying major agribusiness machinery was still difficult, especially in New Zealand, and at present, prohibitively expensive."
Read moreRNZ's Eloise Gibson reports on Rewiring Aotearoa's Machine Count report, which showed that New Zealand has 10 million fossil-fuelled machines, and more than 80 percent of them could be replaced by electric alternatives. [The report] found upgrading six million of the most easily 'electrifiable' machines in the country - including cars, heaters, lawnmowers, road bikes, ovens and stoves - would save the country approximately $8 million a day, or $3.7 billion each year.

We love a tipping point at Rewiring. We reached an important one last year when our Electric Home research showed that New Zealand was one of the first countries in the world where buying and running electric machines in your home was cheaper than gas and petrol equivalents. And we may have reached another one recently because residential gas connections have dropped from 291,586 in mid-December to 290,530 in mid-April.
Read moreSubstitution, not sacrifice. Lifetime savings, not upfront costs. Cheap locally-made electrons, not expensive foreign molecules. These were the main messages at Wheels at Wānaka, where around 65,000 people streamed through the gates to honour the past and get a glimpse of the electric future. TVNZ's Jared McCulloch was there to capture the action, and he stopped in to talk about Forest Lodge Orchard's electric 1990 Toyota Hilux.

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
Read moreShareable linkDownloadOverall, 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.

While the proposed Consumer and Data Product Bill takes a step in that direction, it does not offer the level of freedom that could be technically accomplished, nor the level of freedom that is likely to unlock the maximum level of innovation.
Read moreShareable linkDownloadRakiura / Stewart Island faces the highest electricity prices in New Zealand. Successive governments have funded report after report and numerous fly-in visits by Ministers have failed to change this situation for the local community. Rewiring Aotearoa believes the opportunity is to harness existing solar and battery technology to deliver significant cost-of-living savings and reduced emissions at scale via electrification on Stewart Island right now. With financed solar and batteries, electricity usage costs for residents could be halved without delay. Rewiring Aotearoa has been engaging with the local community, who have been sending us their power bills. On Saturday 27th April some of the Rewiring team visited Stewart Island (including Mike Rewi who has strong whakapapa to Stewart Island). What we are hearing from this community is many locals fear the proposals and the likely “preferred option” will be focused on replacing current diesel generators, not on reducing the cost of energy for consumers. Our proposal outlines Rewiring Aotearoa’s pitch for an alternative approach to develop a community-led energy solution for the Island.

Rewiring Aotearoa believes one such outcome from market innovation is supporting the electrification opportunity for Aotearoa New Zealand. The Commission has the opportunity to play an active role in driving this not just through the energy market, but also through the personal banking market. It is important that these functions are not seen in isolation, but as a system, to better realise the Commission's role in delivering on NZ’s emissions reduction plan, and 2050 Nationally Determined Contribution.

A new report has shown that, on average, homes currently using gas appliances and petrol vehicles could save thousands every year if they went electric and got their electricity from a combination of rooftop solar, home battery and New Zealand’s already highly renewable grid.

However, today there is a systemic bias towards traditional infrastructure largely because it is seen as significantly more ‘dependable’. There are a variety of historical reasons for this. Our primary context to this submission is that many of the assumptions and rationale for this bias are quickly falling away, and DPP4 provides a significant opportunity for the Commerce Commission (the Commission) to reset the assumptions and correct some of this bias.

The EA has the ability to take a leadership role in the energy transition on behalf of electricity consumers. Far more than the Commerce Commission’s oversight of EDBs investment plans, the EA’s network pricing workplan gives consumers agency in the development of the electricity system. When consumer agency is stifled, they will likely have significantly worse financial outcomes on their bills. Much of the necessary changes have been demonstrated already locally or overseas, and the remaining question is not if the changes are possible but if we as a nation will have the courage to implement them on the timeline required to drive better energy transition outcomes for consumers.

Read morePlenty of people need cars (and plenty of people still want them), and other vehicles are literal engines of prosperity. We don't have to give them up to reach our climate goals. We just need them to be electric.
Read moreSolar on our rooftops, farms and businesses can displace the emissions generated by burning fossil fuels in our homes and especially our cars, provide the extra electricity we need to run our electric machines, help bring the cost of electricity down for everyone on the network, and improve our energy security by keeping water in our hydro lakes for when we need it most.
Read moreWe often hear from people who aren’t sure if switching to an electric alternative is the right move. One of the most common questions we get asked is ‘will switching to an electric machine actually reduce my carbon footprint if creating the new machine or materials produces emissions?’It’s a fair question, and we completely agree it’s important to think about the full life cycle of the products we buy and use. Electric alternatives, including vehicles, often produce more emissions than fossil fuel equivalents during manufacturing. But, over the lifetime of the machine, they create much less carbon pollution because they don't burn any fuel.
Read moreFossil fuels for homes, transport and industrial processes make up the vast majority of the country’s total energy consumption. Electrifying the machines that use these fossil fuels means we will use more electricity but much less energy overall.
Read moreAn electrified energy system is actually full of opportunities for redesign, reuse, recovery and recycling. There are opportunities for innovators and entrepreneurs to generate value across the lifespan of every energy asset, not least the return of its components to the manufacturing cycle. To explore this further, Rewiring Aotearoa has partnered with Circularity, local experts in circular design and strategy, to explain what the circular economy is, how to integrate circularity into the design of energy systems, and the role of policy strategy to make it happen.
Read moreThere are no free lunches in energy. But some lunches are far, far cheaper than others. Electrifying everything will massively reduce the overall material and energy requirements of the global energy system. This can be said with high confidence. To be sure, renewable energy systems take materials and energy to build. But this is dwarfed by the mind-boggling scale of extraction, consumption and wastefulness of fossil energy.
Read morePeople sometimes talk about ‘carbon tunnel vision’ – that is, the single-minded pursuit of emission reductions at the sake of everything else. But this is the wrong way to think about electrification. It isn’t only about emissions (even though preventing the world from dangerous overheating is quite the co-benefit). It isn’t only about the tech or the kit: the rooftop solar panels, the batteries, the electrified appliances and vehicles. These are just the means to an end. Electrification is about people and it is a fundamentally better way to power our lives and livelihoods.
