Almost A Third Of NZ Households Face Energy Hardship – Reform Has To Go Beyond Cheaper Off-Peak Power
The Commerce Commission and the Electricity Authority has already established a joint task force, after prices peaked in 2024, to investigate ways to improve the performance of the electricity market.
The Authority recently announced new rules requiring larger electricity retailers to offer lower off-peak power prices from next year. The government is also expected to make further announcements on the sector.
But the question is whether these changes will do enough to help New Zealanders live affordably in dry and warm homes.
Some 30% of households face energy hardship. This means they struggle to afford or access sufficient energy to meet their daily needs.
Caused by a combination of poor housing quality, high energy costs and the specific needs of vulnerable residents, energy hardship can lead to serious health issues and high hospital admission costs.
We know from our own research over the past 18 years that having power disconnected can negatively affect health and wellbeing.
People have told us that not being able to afford enough power to keep warm made them more likely to get sick and exacerbated existing health conditions. They described mental distress from unaffordable electricity and the threat of disconnection.
Research participants used words such as 'stressed', 'anxious' or 'depressed'. They also spoke about having to choose between food and power bills.
If power is disconnected, there can be additional costs from losing food in the fridge and freezer, as well as the problem of paying disconnection and reconnection fees when people already can't afford the bill.
What's driving up power bills?
In 2024, a 'dry year' that increased the value of hydro generation, combined with lower-than-usual wind and declining supply of gas, resulted in wholesale electricity price spikes. But these winter shortages aren't the only factor pushing up power bills.
Electricity bills reflect several costs along the supply chain from generation to getting the electricity to the sockets in our homes. A new regulatory period for lines charges from April 2025 increased bills by $10 to $25 per month, depending on where you live.
At the same time, low fixed daily charges are being phased out. This means the cost of being connected to the grid is the same no matter how much power is used.
It is the poorest New Zealanders who are being hardest hit. The lowest income households spend a bigger proportion of their income on power compared to higher income households. Having electricity prices increase faster than inflation will put even more families at risk.
The average household electricity bill was up 8.7% in May 2025 compared to June 2024. According to a recent Consumer NZ survey, 20% of respondents said they struggled to pay their power bill in the past year.
Tackling hardship
The new Consumer Care Obligations might help reduce some of the risks. Power companies must now comply with these obligations when working with households struggling to pay their bills, are facing disconnection or have someone in the home who is medically dependent on electricity.
If households feel their power company is not meeting these obligations, they can contact Utilities Disputes, a free independent electricity and gas complaint resolution service, or the Electricity Authority.
But multiple changes are needed to address the different parts of the energy hardship problem. Improving home energy efficiency through schemes like Warmer Kiwi Homes is crucial.
Introducing an Energy Performance Rating for houses would make it easier for home buyers and renters to know how much it will cost to power a home before they move in. This would also help target energy hardship support.
The government can also make electricity more affordable by supporting not-for-profit power companies. Another good move would be to help more households to install rooftop solar by providing access to long-term low-interest finance.
Lower prices during off-peak hours are a good start. But it is clear the sheer size and complexity of the problems mean government action, with community and industry collaboration, needs to go beyond slightly cheaper electricity when there is less demand.

'Call me Mr Cash Man': MP seeks protection for hard currency
Self-proclaimed cash advocate and MP Jamie Arbuckle believes his proposed law protecting hard currency transactions is about more than accessibility — it's also about privacy and preventing "Big Brother" surveillance. The New Zealand First MP's members' legislation, the Cash Transactions Protection Bill, would require vendors to accept cash up to the value of $500, with no limits on the amount of cash that must be accepted for essential items like fuel and food. 'There's a real concern across New Zealand that we're becoming a cashless society, and we've got a lot of people who depend on cash,' the MP told Q+A. He said that particularly applied to people living in rural areas, the elderly who are more comfortable using cash than digital systems, and those on low incomes. A self-professed fan of using cash, Arbuckle said, 'cash is king, and you can call me Mr Cash Man if you like.' ADVERTISEMENT 'I've got to tell you right now, I don't like walking into a shop and not being able to pay cash for a coffee.' Composite image by Vania Chandrawidjaja (Source: iStock/1News) But he said in an increasingly digital world, there was a more serious point to be made about the ability to make anonymous payments. 'People are telling me they want to have the ability to use cash, it's a freedom of choice issue.' 'It's really the only true way of having privacy in a transaction. You don't get that with electronic payments. There's always the concern that Big Brother or someone is able to look at where you've been, what you've purchased, so the majority of people have been very positive about protecting cash use.' A Reserve Bank survey released in June 2025 found that — while electronic and debit card use was by far the most common method of making payments — a significant minority of the country continued to use cash regularly. Around 46% of respondents said they used cash 'to pay for everyday things', down slightly from 48% which an equivalent survey found in June 2023. ADVERTISEMENT The survey also found a majority had used cash at least once in the seven days preceding the survey being taken, with approximately 33% of respondents saying they hadn't used cash in the last week, and a further 3.6% saying they would never use cash. Further research undertaken last year by the Reserve Bank found Kiwis value being able to use physical cash. Director of money and cash Ian Woolford said, '84% of respondents were worried about losing access to banknotes and coins, and want assurance that cash will still be issued by the Reserve Bank and not reduced or replaced by digital cash.' 'We'll keep issuing cash for as long as New Zealanders want to use it," he said in December. "We're doing a lot of work to redesign the cash system, including helping retailers through community cash services trials next year in several rural communities lacking over-the-counter bank or ATM services.' Some businesses have moved to being cash-free, but Arbuckle said in his view, it couldn't be an opt-in and opt-out system. 'The majority of businesses hold cash, so we're only talking about a small amount of businesses that would have to change. ADVERTISEMENT "Cash is legal tender, and you should be able to purchase with cash.' He said if the bill is pulled out of the member's bill biscuit tin, he'd welcome feedback from businesses that might be affected during the select committee process.

Winston Peters immigration comments labelled ‘divisive rhetoric', ‘cynical politicking'
The remarks have not gone down well with two of the Opposition parties. The Greens' immigration spokesman Ricardo Menendez March said Peters' 'tired, decades-old playbook of blaming migrants' was a 'distraction' from other actions the coalition Government had taken, such as changes to pay equity rules and tightening emergency housing settings, which critics argue has led to an increase in homelessness. 'We aren't waiting for [Prime Minister Christopher] Luxon to show leadership and shut down this divisive rhetoric, which is why we are fighting to create 40,000 new jobs through a Greens Job Guarantee, build enough public housing and restore pay equity claims,' the Green MP told the Herald. 'We will also ensure every migrant worker is treated with respect and is free from exploitation.' The Greens' Ricardo Menéndez March was critical of the comments. Photo / Mark Mitchell Phil Twyford from Labour told Newstalk ZB it was 'cynical politicking' by Peters. 'Instead of focusing on the things that I think are important to New Zealanders, like the cost of living, they are resorting to imported culture wars that, frankly, New Zealand just doesn't need,' Twyford said. While he said there was always more to be done to improve the system, Twyford said New Zealand 'is completely reliant on immigration for our economy to work and for our society to work'. 'Migrants make a hugely positive contribution to this country. They enrich our communities. It's not helpful for politicians, for their own political purposes, to be trying to divide the community and turn one group of people against another.' Luxon on Sunday said it was important immigration was linked to 'our economic agenda and our ability to support immigration with good infrastructure'. 'Those are the three things that have to come together for any country, and certainly here in New Zealand as well,' the Prime Minister said. 'We have accelerated pathways for residency through the Green List for when we have got job shortages that we desperately need to get into our communities.' Prime Minister Christopher Luxon said immigration needed to be linked to the country's economic agenda. Photo / Mark Mitchell Peters told the Herald NZ First believed immigration should not be used as an 'excuse for our failure to train, skill and employ our own people'. That was one of the party's founding principles 32 years ago and remained 'as much a principle now as it was back then', Peters said. 'We, like wise countries, have always believed we should be training and employing our own people first and not use immigration as an excuse not to do that. That is still our plan.' He said New Zealand still didn't have strong enough initiatives to 'take people from secondary school into employment' and stressed the need for appropriate infrastructure to be in place to support migrants. 'There was a time when we were getting people from around the world putting down £10 to get here. They were coming to a job and a house and infrastructure, schooling, everything. Teachers and doctors and all sorts of people were coming here.' In the year to May 2025, there was a net migration gain of 15,000, driven by 140,000 arrivals and offset by 125,000 departures. The number of arrivals is down from a peak of roughly 235,000 in late 2023, but still above the long-term average of 119,000. However, due to the large number of departures, the net gain is below the average of nearly 28,000. Jamie Ensor is a political reporter in the NZ Herald press gallery team based at Parliament.
