Why drilling for fossil fuels is not expected to fix our energy crisis
RNZ / Samuel Rillstone
Six months ago, Taranaki businessman John Burling received an abrupt call: his gas company was increasing prices by 40 percent.
Burling, who owns the Taranaki-based Carac Group engineering and manufacturing company, was floored. "What do you mean? How do I pass it on?'"
The reply was stark. "There's a shortage of gas, so that's going to be the new price."
Overnight, Carac Group had to cut powder coating plant operations from five days to four, shelving expansion plans and curtailing production due to the energy-intensive gas-fired ovens.
Across the country, many businesses are facing the same gas woes.
"The untold story here is that there's a very large number of smaller industrial businesses that rely on gas and frankly they're gonna struggle to stay afloat," says Barney Irvine, executive director of the Northern Infrastructure Forum. "A lot of these businesses are feeling very desperate and pretty lost."

New Zealand's natural gas is drawn from wells in Taranaki, on the North Island's wild west coast. Around 290,000 households use gas for cooking and heating; in business, it is burned at dairy factories, fertiliser plants and in manufacturing. It's also used to produce electricity when there's not enough power generated from wind, water or the sun.
Until recently, gas was reliable, even when other energy sources were scarce. But now, our wells are old and in decline, and our gas supply is dwindling, fast.
Data
released by
the Ministry of Business, Innovation and Employment (MBIE) in June reveals gas production has almost halved in the last ten years. Supply in February 2024 was the lowest since the 1980s. Gas reserves - the estimated available gas in the deep, underground reservoirs - have also fallen sharply, down 27 percent in the year to January. Forecasts say there is barely enough gas left in our existing oil and gas fields to last the decade, and even that is an optimistic guess.
Demand now outstrips supply, forcing some businesses to struggle for gas, others onto 'demand management' plans requiring production shutdowns to support the electricity grid, and some to close operations entirely.
"In my opinion gas supply is currently our most pressing energy security issue," says energy commentator Larry Blair. "The scale of the problem is huge, and we don't have any readily available alternatives to turn to."
To combat the shortfall, the government has repealed the former Labour government's 2018 ban on new offshore oil and gas exploration permits. The policy aims to 'future-proof' the natural gas industry and reduce reliance on imported coal during dry years when hydro dams are low.
The bill, spearheaded by Resources Minister Shane Jones, passed in the House last week. Coupled with a $200m co-investment in gas exploration, Jones says the policy will signal to international petrochemical companies New Zealand is "open for business".
"It's to send a message that we will invest with you if it's appropriate as the Crown, but more importantly, there is a long-term future in New Zealand in terms of how we power our economy by using gas or coal."
Industry has celebrated the law change. John Carnegie, chief executive of Energy Resources Aotearoa called the bill a "pragmatic and necessary step to help rebuild investor confidence."
Jones and the Prime Minister, Christopher Luxon, have blamed the 2018 exploration ban for the current state of the gas market.
"The basic problem is that we don't have enough gas thanks to Labour screwing the scrum by banning oil and gas," Luxon told Morning Report last month.

Jones has said the ban, which was implemented to address climate change, was
"the most destructive decision in the history of New Zealand's industry."
But experts, including the government's own officials, warned the ban was not the main driver behind a lack of investment in gas or New Zealand's high energy prices - and won't be a magic fix for them either.
Global investment in speculative drilling for oil and gas has been declining since 2014, when the oil price crashed. Since then, oil companies have focused on high-ranking, lower-cost petroleum provinces, putting New Zealand at a "geographical and geological disadvantage" due to its isolation and relatively unexplored status, officials wrote in a Cabinet paper last year.
Records show that even before 2018, most of the major oil companies had given up their exploration permits and left New Zealand, citing "bad data", high technical risk or better opportunities elsewhere.
"Clearly the ban was an important nail in the coffin," says Green Party MP Steve Abel, who worked on Greenpeace's oil and gas campaign. "But the government also should have been well aware of the obvious evidence that gas was running out and no one was interested in drilling for more, even though a lot of oil majors came and had a look."
Whether those companies can be lured back will largely depend on whether we have enough big buyers to make it worth their while. New Zealand has a closed gas market, meaning there are no exports. Instead, local supply must meet local demand.
Historically, developing new gas fields has relied on big contracts from major users like methanol producer Methanex. But if demand from those large industrial users drops, it poses a risk that the remaining, smaller users might not be able to purchase enough gas to support new investment. Currently, demand is dropping rapidly - advice from officials on the $200m investment shows overall gas use has fallen by about a third since 2020, as companies close because of high prices, or decarbonise in the face of climate change.
"At this point, the market is collapsing faster than we can put new reserves back into it," Larry Blair says. There is also the
lingering damage
by the ban to the country's reputation as a safe place to invest, and the very real risk that the policy could be re-reversed with a change of government. "The problem I see for people looking at New Zealand is there's no confidence that there's a sustainable market there in the long term."
With such strong headwinds, experts say the $200m is unlikely to suddenly make it commercially viable to take a big gamble on entirely new discoveries, particularly when New Zealand hasn't found new gas in a new place for
two decades or longer.
It's more likely the money will be used to fossick around in our existing fields, trying to retrieve what's left.
The government knows this. Its own advice has
acknowledged
the plan's flaws and its low certainty of success. "Investments may not all be successful. The risk of failed drilling is high in our mature fields. In the last five years around $1.8 billion has been invested in drilling 58 wells, and this investment has not managed to maintain or increase our gas reserves," MBIE's advice to Jones in March this year said.
Even if the analysts are wrong, there is still the matter of timing. Data shows a new gas field could take a decade, or longer, to find, develop, and bring online.
"There will be nothing left to power by then," says Consumer NZ chief executive Jon Duffy.
"Why are we doubling down on expanding what is clearly an industry in decline? In my view we are taking an absolute wrong turn."
Critics like Duffy say more needs to be done now to bring down gas and electricity prices and shore up energy supply.
Last month, an influential collection of energy users and advocacy groups
called on Luxon
to urgently fix the "broken" energy sector, which they said was crippling industry and leaving families freezing during winter.
"Regional employers are shutting their doors, with hundreds of jobs and decades of investment lost," it said. "Families and communities are being left behind."
Luxon is also under pressure from climate advocates, who have said the bill is "tipping oil on the climate crisis fire." A government Climate Implications of Policy Assessment (CIPA) estimated that reversing the ban would lead to a "substantial increase in emissions" of approximately 14.2 million tonnes of carbon by 2035, primarily from prolonged gas usage in electricity, commercial, and industrial sectors.
Drilling for gas would make it harder for New Zealand to meet climate change targets, but could also
undermine its obligations
under the Paris Agreement, risk trade deals and
breach international law
, critics said.
"From a climate change point of view, which everyone should be worried about, we can't afford to burn the existing fossil fuels that have already been discovered on the planet," said Greenpeace executive director Russel Norman. "But also, potentially, you are facing liabilities from other countries who are negatively affected by you burning more and more fossil fuels and destabilizing the climate. So it's grossly irresponsible."

Jones recently said he considers climate change
"largely moral hysteria."
He said the
recent judgment
from the International Court of Justice (ICJ) would not halt legitimate New Zealand industries.
"Some people might try to use it, exploit it to undermine industry, undermine investment, stop manufacturing … but we will not allow our sovereignty to be compromised," Jones said.
Instead, he has pitched gas as a "transition fuel" to reduce dependency on Indonesian coal to "keep the lights on". The government also plans to double geothermal energy.
Plans to transition away from gas itself were shelved when the coalition was elected, alongside a plan to help fossil fuel workers retrain in low-emissions industries. While there are
renewable energy projects
in the pipeline it's not expected to be enough to fill the gap, especially as more companies decarbonise.
Electricty Authority data shows more wind farms are in the pipeline, but critics say they need to be built now.

In the same open letter sent last month, the group of concerned organisations called for the government to intervene in the market so more renewables could be built at pace.
"Unlock investment in low-cost, renewable generation," it said. "Investment in new generation is being delayed, sustaining high prices, and contributing to the energy supply crisis we now face."
Commentators say unless we can secure more energy soon, industry closures will begin to pile up as businesses run out of options.
"I don't see a plan B for a lot of industries in New Zealand," says Blair. "That's the brutal reality of it."
Consumer's Jon Duffy says he doesn't think there's a plan at all. "There's no Plan A. What we are really missing is a national energy strategy."
Meanwhile, for industries like John Burling's, there are no good answers. His increased gas bill led to higher costs for running the gas-fired ovens, but Burling was unable to pass these on to customers. "It was a bit of a no-win really," Burling says. He's yet to find an alternative to his gas-fired ovens, and in any case, electricity would be even more expensive than gas.

The people quietly preserving a place for cash
The Reserve Bank is doing its once-every-two-year survey to understand how New Zealanders use, store and spend cash. Photo: 123RF As Kiwis' cash use comes under scrutiny, shopkeepers and emergency savers are among those quietly preserving a place for physical currency. At present, the Reserve Bank is doing its once-every-two-year survey to understand how New Zealanders use, store and spend cash. Dunedin residents, unscientifically surveyed by RNZ on Tuesday, said they were using cash for everything from groceries to public transport, pocket money, cheese rolls and, in Sheryn Wilson's case, to give to the less fortunate. "Occasionally, I'll get out $20 in change and give it to my granddaughter to give to the people along here. That's basically all I use it for. To give the homeless... but that's it," Wilson said. Physical money remained second preference to using a bank card, although she believed it was worthwhile to have a backup stash for emergencies. "It feels strange now to use cash. It feels old-fashioned and kind of dirty," she said. Clive Cockle said he always carried cash but tended to default to swiping his card. He said he also kept at least a few dollars for emergencies. However Daniel, who did not want his last name identified, said he actively avoided cash to try to restrain his spending. "I find it hard to save money if I've got cash lying around - I'll just spend it straight away. If I've got cash, every time I open my wallet, it's gone," he said. Clive Cockle said he keeps at least a few dollars for emergencies. Photo: VNP / Daniela Maoate-Cox This year, the Reserve Bank's random postal survey would ask people how they preferred to pay, how often they used cash, how easy it was to deposit and withdraw coins and notes, and whether they stored cash - and why. Reserve Bank's cash manager Ian Woolford said people's habits were shifting. The last survey found fewer people using cash day-to-day, but those who did used it more often and more people said they valued it for privacy and safety. "The work that we're doing is to make sure that consumers - citizens - can use it when and as they please," he said. The Dairy and Business Owners Group said it was becoming harder for shopkeepers to manage cash. Chairperson Ankit Bansal said some people were relying on dairies for small cash withdrawals when there were not banks nearby. But the reduced number of bank branches and the increase in 'cashless' banks made it hard for shopkeepers to maintain a float. Bansal said stores needed easy bank access because holding money on site was a safety risk. "Banks - this is their job. Essentially we're seeing them picking and choosing what services they're providing. So I hope to see some action on the banks," he said. Retail New Zealand chief executive Carolyn Young said cash was on the way out, although not in the near future. Fewer than one in ten nationwide retail transactions were now in cash, she said. "It's certainly always diminishing, but how long that tail is, we're not sure," Young said. Shopkeepers were not supportive of New Zealand First's recent members' bill, which would require making it mandatory for stores to take cash for purchases up to $500, she said. "Retailers... understand that cash is important, but they don't want to be dictated - that it's mandated. Part of it is what do people want and how do we make sure that that's working. It's not broken at the moment. We don't think that it's necessary," Young said. Jamie Jermain, the co-founder of the SquareOne app that helps children understand finance and managing their money, found some children didn't know what cash was. He said a tool kit was needed to teach children about money and it's value when cash is increasingly invisible in a digital world. "In this day in age, what kids are getting more and more used to seeing is their parents essentially tapping this magic wand on a terminal. They [young people] don't have that connection with money, they don't see how it works on a day-to-day basis," Jermain said. Educating children on how to earn, save and responsibly spend money is crucial for learning good money habits when children get older, Jermain said. "Those lessons are with them for life," he said. The Reserve Bank's survey closes on 10 October. Sign up for Ngā Pitopito Kōrero , a daily newsletter curated by our editors and delivered straight to your inbox every weekday.

Waimakariri's new councillors may get 22% pay bump
Deputy Mayor Neville Atkinson and Mayor Dan Gordon. Photo: Waimakariri District Council. Photo: LDR / SUPPLIED Waimakariri's mayor and councillors are set for pay rises of up to 22 percent after October's election. Councillor pay rates will jump from $58,110 to $71,026. Speaking at a council meeting on Tuesday, outgoing Deputy Mayor Neville Atkinson said councillors were "well worth" the increased pay rate. The mayor's salary is set to rise 4 percent, from $158,057 to $164,728, while the deputy mayor's salary is proposed to jump 22 percent, from $74,674 to $91,271. The pay jumps are due to an increased remuneration pool. Atkinson said voting on pay rises is "silly" when it is already set by the Remuneration Authority. "It is imposed on you and it has always seemed silly to me that we have to vote on this, when it is already imposed on us. "If you want to give it to charity you can, but if you want to take it, then good on you - you are well worth it." Atkinson said there was plenty of commentary on social media about what bonuses councillors allegedly claimed. "It talks about the bonuses which we actually don't get. We don't get flying allowances - we don't want them, and we don't get lunch allowances - we don't want them. "We want to look after ratepayers' money. "But this extra money will allow people to make a conscious decision of whether they want a full-time job alongside being a councillor or not." Retiring councillor Al Blackie said while councillors did not do it for the money, they did have a big workload. ''A little bit more money in the pot can only be a good thing in encouraging young people and particularly young women to stand.'' Councillor Tim Fulton said his only concern was the ''gaps'' in the childcare allowance, which will increase from $6000 a year to $7500 a year per child. He said it did not take into account the sacrifices a spouse of an elected member might have to make when arranging childcare. Waimakariri District Council governance manager Sarah Nichols said the childcare allowance could not be used to pay a partner or grandparents. ''It is generally used for an independent person or for childcare facilities. ''We have had a handful of members who have claimed it in the time we've had it, and it has never been for anywhere near the total amount allowed.'' The Hurunui District Council last week voted against offering a childcare allowance, despite the support or four councillors. There was no opposition expressed by the 10 councillors or Mayor Dan Gordon to the remuneration package presented, which also includes payrises for community board members. The Remuneration Authority recently completed a review how it determines local government remuneration and well recommended no changes. It considers population, economic growth and the geographic area of the district when setting the remuneration pool for the deputy mayor councillors' salaries. Pay rates across the country vary from about $20,000 at the lower end, to more than $300,000 for Auckland mayor. The payrises for the deputy mayor and remaining nine councillors will be finalised after the local government elections on October 11. LDR is local body journalism co-funded by RNZ and NZ On Air.

Cybersecurity warning: 'Widespread exposure of compromised credentials'
Employee records linked to more than 198,000 NZ companies and entities were found on the dark web. File photo. Photo: Andrew Brookes, AB Still Ltd, Thousands of leaked credentials for employees from NZ government departments and healthcare organisations can be found on the dark web, says a digital security firm. The data is part of more than 150 million compromised records connected to New Zealand that is accessible on the dark web, according to a study by Kiwi tech start-up nWebbed Intelligence. The company's cybersecurity study analysed more than 30 billion credentials available for sale on the dark web and found links to more than 198,000 New Zealand companies and entities. It also found the usernames and passwords of more than 18,000 NZ government workers, 3200 banking staff and 2000 healthcare organisation accounts were also found in leaked databases. nWebbed Intelligence founder Julian Wendt said local organisations were underestimating the scale of cyber risk, and am urgent review of cybersecurity protocols was needed in the country's sensitive institutions and corporations. "We are seeing widespread exposure of compromised credentials linked to core parts of the New Zealand economy, including health providers, government agencies, banks and large-scale businesses. "These are trusted institutions that Kiwis interact with every day, and they are real emails and passwords sitting in the wild. They're searchable, for sale and vulnerable to exploitation." He said some breaches were going undetected for years. "It's not that someone was hacked once and that's it. In many cases, credentials from five or six separate breaches are still sitting out there, waiting to be exploited." Qantas recently revealed an attack by cybercriminals may have accessed as many as six million customer records.
