2025 confirmed as one of the hottest years on record

An ‘addiction’ to fossil fuels is driving climate change, the UN Secretary-General says – leading to ever-more severe weather including floods, droughts, and damaging storms. MUHAMMAD FAROOQ

Last year was among the hottest on record, as the world’s “addiction” to fossil fuels continues to drive global warming, new data shows.

The World Meteorological Organisation (WMO) confirmed the average global temperature last year was 1.43°C warmer than the 1850-1900 pre-industrial average.

2024 remains the hottest year on record, but 2025 was the second- or third-hottest, across the nine major global datasets.

The organisation said the global climate was more out of balance than at any other time in observed history, as greenhouse gas concentrations reached their highest levels in at least 800,000 years.

Most of the trapped heat was stored in the ocean, which is warming at an accelerating pace.

Together with melting sea ice and glaciers, that was driving global sea level rise – which projections from the Intergovernmental Panel on Climate Change show will continue for centuries.

Arctic sea-ice hit a record low in some satellite datasets last year.

UN Secretary-General Antonio Guterres said the planet was being pushed beyond its limits.

“Every key climate indicator is flashing red.”

Current major conflicts were exposing another truth, Guterres said.

“Our addiction to fossil fuels is destabilising both the climate and global security.”

Iran’s closure of the Strait of Hormuz, after the country was attacked by Israel and the US, has spiked oil and gas prices and prompted fears of global inflation.

The WMO’s State of the Climate report said increasingly severe weather, driven by climate change, was already affecting agricultural production and displacing people from their homes.

“The cascading and compounding impacts of multiple, sequential disasters severely limit the ability of communities to prepare for, recover from and adapt to shocks,” the report said.

That was especially true in places that were already experiencing conflict or other types of insecurity.

In New Zealand, inflation-adjusted data published by the Insurance Council showed that since 2019, insurance companies had paid out nearly $6 billion for extreme weather-related events in New Zealand.

That did not include pay-outs for severe weather at the beginning of this year, which killed six people in a landslide at Mount Maunganui, cut off entire communities, and closed major roads.

Victoria University professor of climate science James Renwick said the science of climate change had been understood for a century or more now.

“We know what we have to do to stop it,” he said. “Stop burning fossil fuels.”

Policymakers had been given that message for decades but emissions just kept increasing, he said.

He hoped the latest report “moves the dial”.

“The costs of inaction are already astronomical, let’s not make them overwhelming.”

Last week, the High Court in Wellington heard a case taken by two environmental NGOs against the government over its emissions reductions plans, which the organisations argued were risky and unlawful.

The Environmental Law Initiative and Lawyers for Climate Action told the court that the government broke the law when it dismantled dozens of climate policies soon after the election, before it had consulted the public.

The current plan relied overwhelmingly on offsetting emissions by planting forestry, rather than tackling emissions at their sources, the organisations said.

The court has reserved its decision.

Similar cases in the UK succeeded in forcing the government there to re-write its own emissions plans.

Shane Jones labels critics of fisheries bill as ‘noisy voices’

Oceans and Fisheries Minister Shane Jones has called critics of his Fisheries Amendment Bill “a range of noisy voices” and invited them to have their say at the select committee.

The bill, which is scheduled to have it’s first reading on Tuesday, has been welcomed by the commercial sector but condemned by recreational fishing groups.

Fishing Host Matt Watson – probably the country’s most famous recreational fisher – is dismayed by the proposals in the fishing amendment bill.

He told First Up the bill’s “designed purely to prioritise the profits of the seafood industry”.

“If these go through unchecked, it is disaster. It’s beginning of the end for our fish stocks, and that’ not over dramatising it.”

Among Watson’s concerns is the proposal to remove the minimum size limits for commercial fishers from a number of popular species, including snapper.

He said it wouldn’t encourage commercial fishers to avoid undersized fish and would decrease overall fish stocks.

The current recreational size limit for snapper is between 25cm and 30cm depending on location, while the commercial size limit is 25cm.

Minimum size limits are imposed to ensure fish can reach sexual maturity before being caught.

“If you start killing fish before they’ve had a chance to breed, you’re going to run out of fish and you don’t need to be a genius to figure that out,” Watson said.

Jones argued that allowing the commercial sector to land and sell undersize fish would prevent wastage.

Currently commercial fishers must dump undersize fish dead or alive, and it doesn’t count against their quota.

“The new provision is that if you catch them, you pay for them,” Jones said.

“With the commercial industry, we know every single kilo that they take and their conduct is now captured by cameras.”

But if Jones’ bill passes, the footage taken by cameras on board commercial boats can no longer be accessed under the official information act, effectively making it off limits to the public.

Anyone who leaks the footage faces a $50,000 fine.

“If you’ve got nothing to hide, why on earth would you behave like that,” Sam Woolford of recreational advocacy group Legasea said.

“When cameras on boats were introduced, we know that the rate of discarding, or notified discards, went up about 46 percent. For snapper and kingfish, it was closer to 1000 percent.”

Jones, a self described apostle of industry, brushed off the concerns about snapper stocks, telling First Up the “amount of snapper in our waters is almost biblical in its profundity”.

“You can almost walk on the water we’ve got so many snapper.”

Coalition support means the Fisheries Amendment Bill should easily pass it’s first reading, but Labour’s fisheries and Oceans spokesperson Rachel Boyack said she would make her concerns heard at the select committee stage.

She said her party would do their “best to make changes to the bill so that it’s not as bad as what it could be.”

Although with commercial fishing a strong feature of her Nelson electorate, Boyack was choosing her words carefully .

“It creates jobs in my local community and it’s important that we are able to produce fish for food and for export, but we also have to ensure that the fishery is sustainable”.

Conservation Minister Tama Potaka’s office didn’t respond to requests for comment, but in a facebook post Northland MP Grant McCallum said he met with Legasea and the sports fishing council over the weekend and would strongly represent the views of the recreational sector in the party’s caucus this week.

Seafood New Zealand’s Inshore Policy Manager Tamar Wells said the commercial sector was trying to make the industry more sustainable.

“Fishers do change their methods. In terms of their selectivity of their nets, they’ll have larger mesh to let smaller fish out.

“There’s also new methods coming in, like Flowmo, which is a type of net that can keep fish kind of contained underwater so they have a higher survivability.”

The Fisheries Amendment Bill won’t require commercial fishers to change their methods though and Jones said there was no plan to outlaw trawling.

“It’s evident to me that the vast majority of the activists opposed to trawling are really seeking to undo the Māori fisheries settlement and terminate the commercial fishing industry and that’s just never, ever going to happen for as long as I’m in politics, and I look forward to being in politics for a long, long time.”

All Blacks assistant coach Scott McLeod is crossing the ditch.

McLeod has been recruited by the Wallabies to take up a position as the side’s defence coach for the next three years.

The 53-year-old was a member of the All Blacks coaching team at the last two Rugby World Cups, serving under Steve Hansen and then Ian Foster.

He will join the Wallabies ahead of the 8 August test against Japan, which will mark Les Kiss’ first game as Wallabies head coach.

Born in Brisbane, McLeod was raised in New Zealand and represented the Chiefs across 44 Super 12 games and the All Blacks in 10 tests.

After an eight-year playing stint in Japan, McLeod returned to New Zealand to embark on a coaching career with Waikato, the Chiefs and Highlanders, before taking on the role of All Blacks assistant coach in 2017.

McLeod most recently served as an assistant with the Kubota Spears in Japan’s Rugby League One.

“I am very excited to return to international rugby, especially to join up with Les and the team to build on the foundations that have been put in place,” McLeod said in a statement.

“There is a lot of excitement building within Rugby Australia and I am really committed to doing my part. I am looking forward to connecting with RA, the players and everyone who is invested in this team.”

Rugby Australia director of high performance, Peter Horne, said from the Highlanders’ first Super Rugby title in 2015 to the most recent Rugby World Cup final, McLeod’s resume and reputation are of the highest calibre.

“Scott has a great understanding of the environment and standards Joe Schmidt has driven since joining the Wallabies, having coached alongside him with the All Blacks, and will provide great support to Les as he transitions into the head coach position.”

Laurie Fisher, who has served as defence coach since 2024 under Joe Schmidt, is set to move into a consultancy role.

Human remains found in garden in Wellington’s Ōwhiro Bay are centuries old

Source: Radio New Zealand

Human remains found in a garden on Wellington’s south coast are centuries old, according to police.

RNZ understands an Ōwhiro Bay homeowner was gardening when they made the discovery in June last year.

At the time, police said the resident was under no suspicion and a forensic anthropologist and pathologist determined the remains were human.

On Monday, detective constable Sarah Steed said radiocarbon dating showed the remains were possibly pre-European from the 1600s-1700s.

“This information will now be supplied to the Coroner for consideration,” she said.

“Consultation will take place with local iwi to arrange a suitable burial site, once the remains are release by the Coroner.”

Some dual British citizens get border exemption from new passports

Some British dual nationals are getting permanent exemptions from needing UK passports to travel there – but the carve-out is not going to help those in New Zealand.

A low-key change has allowed EU nationals granted British citizenship after Brexit to circumvent the new border requirements.

In New Zealand and elsewhere, some dual UK citizens have spent hundreds of dollars to get new British passports, trying to avoid writing off thousands more they have spent on pre-booked holidays.

The border requirement – which means British and Irish citizens can no longer use their New Zealand passport to enter the UK – came into force a month ago.

The policy, first revealed by RNZ in mid-January, caused panic for travellers unaware of the move.

Advocacy groups and immigration lawyers in the UK have since called on the government to rethink several aspects of its programme.

They only discovered the new passport exemption for European dual nationals given settlement status in Britain after Brexit through Home Office correspondence about the ongoing saga two weeks ago.

The British government website now sets out how citizens of EU and other European countries such as Switzerland will not need a UK passport to travel there.

UK lobby group the3million – named after the EU migrants living and voting there – said it welcomed the government’s partial u-turn, but said it still left many others struggling to navigate citizenship and passport complexities.

“It’s for a very precise group – it’s for those EU/EEA/Swiss citizens and their family members who were living in the UK and applied for status under the EU Settlement Scheme,” its spokeswoman Monique Hawkins told RNZ.

“This is the cohort that can benefit from this new concession.”

The group wants the UK government to go much further in changing the passport requirements and allowing a grace period for people who have not yet got a UK passport, or did not know they needed one.

“As the world moves towards digital travel documentation, we do not see that dual citizens should be forced to maintain two sets of expensive physical documents if they do not want to do so.”

Hawkins also took aim at the digital Certificate of Entitlement (CoE), which is an alternative – albeit ‘extremely expensive’ – to keeping a second passport.

“We are fully aware that these no longer need to be renewed; however, £589 [NZ$1347] is still more than six times the cost of an adult British passport, each of which lasts for 10 years,” said a joint letter to the Home Office.

“It would therefore take more than 60 years before the cost of a CoE outweighs the cost of passport renewals, and for a family the multiplied cost is likely to be unaffordable.”

The letter also points out that some European dual nationals will now not even need a passport to enter the UK, but only a national ID card from their country of origin.

“Although this was not one of the measures we had asked for in our letter, we welcome this change for the cohort who can benefit from it. We note it is a significant departure from the general Home Office position that for a British citizen there is “a legal requirement to hold a valid British passport or Certificate of Entitlement” as stated in the Home Office response to our letter.”

Meanwhile, dual nationals in New Zealand are still struggling with the changes, as well as flight cancellations and uncertainty thrown up by the Middle East conflict.

Travel agents and some airlines have been updating passengers, but others remain unaware of the change or even that they or their children could be British citizens by descent.

Some are against the clock to access ID documents for citizenship and passport applications, waiting on deliveries, or have decided they will be relinquishing their UK citizenship altogether.

A New Zealander told RNZ he was lucky to see news about the rule change before his daughter, who was studying in the UK, took a trip to the Continent – as she would not have been able to return to Britain afterwards.

Previously, dual citizens had been able to visit the UK on a New Zealand passport, more recently with an ETA, an electronic online declaration costing about $37.

The UK’s Guardian newspaper has reported cases of dual national Britons, including teenagers, stuck overseas after going on holiday to Europe or elsewhere and then discovering they need a UK passport to return.

RNZ has heard from people planning to try to travel without a British passport, hoping that check-in and border staff will not know they or their children have dual citizenship.

The UK Home Office and British High Commission have previously warned against that, and suggested people could use expired passports as a temporary measure if airlines agree, while defending their communication of the changes.

Patient dies after ‘burnt out’ brain surgeon ignores advice from colleague

A brain surgeon who refused advice from his colleagues has been stood down after his patient died of a brain bleed post-operation.

A report by the Health and Disability Commissioner found his sarcastic remark to a fellow surgeon, who questioned him on his approach, “inappropriate”, and criticised a culture of silence when it came to questioning senior surgeons at the hospital.

The patient, who the report calls Ms A, then aged 51, received two heart valve replacements in 2012, and then in May 2019 was admitted to hospital with vomiting, diarrhoea and fever, accompanied by delerium and speech issues.

Scans revealed a brain aneurysm, and although she needed urgent cardiac surgery to replace her heart valves, doctors decided the aneurysm needed to be treated before they could operate on her heart.

A surgeon referred to in the report as Dr C performed endovascular surgery, with support from other doctors – but one of those doctors told the HDC that their own involvement was “very passive”, as Dr C was “very used to work[ing] by himself”.

An anaesthetic registrar who was in attendance told HDC they witnessed another doctor entering the room to ask Dr C, “Are you sure you want to do it like that?”

HDC heard from that doctor, who said when Dr C was removing a microcatheter that had become temporarily stuck, it “was not adequately controlled and surged forwards, injuring a more proximal vessel (causing a dissecting pseudo-aneurysm)”.

When he asked Dr C what he was going to do about the pseudo-aneurysm, and Dr C replied: “hat pseudo-aneurysm.”

The woman was transferred back to the ICU following surgery, but those complications caused further bleeding in her brain, and she died six hours after surgery.

Dr Vanessa Caldwell, Deputy Health and Disability Commissioner, found despite the surgery being high risk, and Ms A being very unwell, “there were multiple failings in the system and in decisions made on the day of Ms A’s surgery”.

She says according to Health NZ, Dr C’s workload was “significant” at the time of the event, and “the dynamic of the team was such that no staff member felt empowered to speak up to [Dr C]”.

It said Dr C had a history of persevering despite recommendations from others, and a culture of staying silent had developed.

“Dr C reflected that he may have had an unconscious bias against his colleagues,” the report says, “due to their relative lack of experience”.

They had not worked together long, he said, and they were “still relatively unknown quantities” which “played a definite role in his willingness to take advice from them”.

Caldwell, in her report, finds his sarcastic remark – quoted variously in the report as both “hat pseudo-aneurysm” and “What dissection?” – inappropriate.

“Dr C told HDC that this was made sarcastically in reference to the brain-bleeding because it was so obvious that an injury had occurred.”

She also criticised the quality of his handover to ICU staff post-surgery, which contained a lack of information about the injury’s severity.

Dr C was stood down from performing such surgeries, and last did one in May 2019. He accepted the findings of the HDC report, and extended his condolences to the family.

He said the case had had a huge impact on him personally, his work and his career, and on his family.

Caldwell said Dr C described being “burnt out”, and in her view, Health NZ had an organisational responsibility to staff its service safely.

She recommended a written apology to Ms A’s family from both Dr C and Health NZ.

Health NZ has been approached for further comment.

Rise in cocaine and meth use prompts call for ‘fundamental shift’ in policies

Source: Radio New Zealand

Executive Director of NZ Drug Foundation Sarah Helm. Supplied

The New Zealand Drug foundation is calling for a “fundamental shift” in drug policies in response to dramatic increases in cocaine and methamphetamine consumption.

The foundation said police wastewater testing showed cocaine use reached an all time high during the last quarter of 2025 – exceeding MDMA consumption for the first time.

In that period New Zealanders used an estimated 9.4 kilograms per week – nearly double the average weekly amount consumed over the previous four quarters of 4.7 kilograms per week.

The wastewater report showed during the last three months of 2025 Kiwi’s were also using nearly 34.7 kgs of methamphetamine every week.

The consumption of the drug had held steady over the previous two years after a sudden surge which saw use nearly double from an average estimated figure of 14.64 kgs per week in the year following 2023.

Drug Foundation Executive Director, Sarah Helm said the results were a “stark illustration” that underinvestment in treatment and harm reduction combined with an over reliance on police to interrupt supply wasn’t working.

“The dramatic increases in methamphetamine and cocaine consumption over the last two years are unprecedented.

“Consumption is at record levels, drug use is diversifying, prices are down, harm is increasing, and new potent drugs are arriving. Every indicator is screaming at us to change our approach,” Helm said.

Helm said since it’s introduction in 1975 the Misuse Drug Act had only seen the problems of drug harm worsen in New Zealand.

“We’ve gone from having a small number of substances – causing a small amount of harm – to mass incarceration, a growth in addiction and much more toxic and new substances appearing all the time. It has accelerated harm and we’ve really given it it’s best,” Helm said.

Helm said the foundation sought to remove criminal penalties for drug use – so that people were encouraged to seek help rather than covering up their substance use – as well as addressing parts of the law that criminalised elements of harm reduction initiatives.

“A bunch of the things that we need to be able to do to prevent people from dying or having harms occur are actually criminalised or are made very difficult to conduct under the Act.

“So we do need new law that is centred on evidence and the well-being of people – rather than what has been historically in place for over 50 years,” Helm said.

Helm said the foundation supported the initiatives outlined in the Government’s Action Plan to Prevent and Reduce Substance Harm – announced last week.

The plan included pledges to strengthen early intervention and prevention measures – such as drug checking and health promotion – as well as improving access to community-based support and better data and monitoring of the health system’s performance in the area.

But Helm said “a more fundamental shift” was needed” to reverse the current trends.

“We need step change if we really want to try and get this growth and change in our drug supply and our drug harms under control. If we continue to just do the same kind of thing we will see the harms continue to grow.

“If we could wave a magic wand, we would do two things: vastly increase the spending on addiction treatment and harm reduction, and change our drug laws.

“While these things won’t remove all problems, the evidence is clear that it would reduce the worst harms and provide us with more tools to tackle the increase in harm. But if we continue doing more of the same, things will continue to get worse,” Helm said.

Energy crisis: How to max your fuel efficiency when driving

Source: Radio New Zealand

RNZ / Quin Tauetau

Explainer – With the Iran war leaving supply chains choked off, pain at the pump is rising, but you still need to drive. How can you get the most out of your tank? Here’s some options.

The price of 91 petrol has now heading towards $4 a litre in some parts of the country, the government is mulling weighing in and some have begun to hoard petrol ahead of possible shortages.

Feeling uncertain? Get used to it, for now.

“Nobody has a clue about future petrol, diesel and aviation fuel supplies and their costs,” Massey University Emeritus Professor in Climate Mitigation and Sustainable Energy Ralph Sims said.

There are plenty of other options – public transport, biking or walking if you can, pivoting to electric vehicles – but not everyone can easily take up those alternatives.

If you’re looking to ‘fuelmaxx’ your efficiency, here is more of what experts suggest:

Petrol has risen to more than $3 per litre. Nick Monro / RNZ

Combine your errands

NZTA estimates that short trips use 20 percent more fuel when your engine is cold.

So if you can manage to tie together things like school runs with the grocery shop and a run to the chemist, you can save your overall petrol consumption, AA fuel spokesperson and former general manager of the Energy Efficiency and Conservation Authority Terry Collins told RNZ’s Afternoons.

“Do it all in one trip when the car’s warm – save the fuel, tick off all those little jobs, instead of making them independent trips every time.”

Steady on the acceleration, mate

Sims said that the majority of drivers can save up to 20 percent of fuel use with a few simple changes.

“Most people don’t understand how to drive a car efficiently,” he told RNZ recently.

“I see people accelerate to a red light and then brake heavily, and if you’re running on low tyre pressures, it consumes much more fuel.”

Collins said a lot of it boils down to how you’re driving.

“When we hop in a car what we really want is momentum – movement. So what we do is we use the fuel to gather momentum, but I see every day people wasting that momentum by braking unnecessarily.

“They’re not anticipating the traffic in rush hour, so they’re driving up behind the next car and putting the brakes on. If they could look ahead a number of cars and see that everybody already had their brakes on, they could just drift up behind the other car very slowly and brake.

“Every time you put your foot on the brake, you have lost that momentum for the fuel that you’ve paid for. So think that every time I put my foot on the brake, I’m spending money.”

It’s worth watching your speed on highways, too – Sims said that typically a car at 110km/h uses 10 percent more fuel per kilometre than when travelling at 90 km/h due to greater air friction.

Once upon a time, manual or stick shifts were typically more fuel efficient than automatic transmission vehicles, but thanks to improved technology that’s changing and modern automatics are often as good or slightly better than manuals.

The more you carry, the more you use

Carrying heavy loads will obviously slow your car down, but there are also smaller drags to be aware of.

Modern cars are carefully designed and put through wind tunnels to get the most aerodynamic shape possible, Collins said.

Even leaving roof racks on your car that you never use can add to the drag.

“The moment you put those roof racks on you’re disturbing all that air flow.

“People think ah, they’re OK, but you’d be surprised how much that aerodynamic change affects your fuel consumption.”

New tyres or keeping your old ones properly inflated makes a difference. From Tyrewise.co.nz

Keep up your maintenance

Don’t just think about car services as a way to get your next Warrant of Fitness ticked off. Regular care for your vehicle’s systems can save you money in the long run.

“One of the things we often overlook is just the simple thing of checking your tyres,” Collins said.

Under-inflated tyres can add 10 to 12 percent to your fuel bill, he said.

“You’re just adding drag. … It’s working harder to get that momentum I was talking about earlier.”

Your tyre’s correct pressure should be listed on the vehicle label inside the door or in the handbook. It’s best to check the pressure when the tyres are cold to see how yours are looking.

A dirty air filter or fuel filter can also compromise your efficiency, while old and worn spark plugs may mean you’re not getting enough ignition.

“Just that simple servicing on a regular basis to make sure those jobs are done are going to save you in the vicinity of 10 to 20 percent of your fuel bill,” Collins said.

To A/C, or not to A/C?

This is one of the great existential questions of driving – is it better to wind down your windows or pump up the air con? Studies have had conflicting results and ultimately it’s better to be flexible.

“While it’s more fuel efficient to have it on at 100km/h than it is to have the windows down creating drag, the air con can use around 10 percent more fuel,” the AA’s website states. “You may need to find that balance of comfort and economy.”

A lot may depend on how old your car is and how well maintained the engine and air con systems are.

It’s best to mix and match if you can – windows down and air con off when you’re at town speeds and windows up and air con on if you’re on the motorway.

In general any other unnecessary widgets on your car may also be creating a drag – such as leaving your rear window defroster on long after it’s done the job, or those heated seats when there’s no need to.

Use the technology if you’ve got it

Many newer vehicles are equipped with Auto Stop-Start systems which automatically shut off the engine when a vehicle is in congestion or at traffic lights. As soon as you take your foot off the brake, the engine restarts without delay, Ford NZ explains on its website.

“Your climate control fan, audio system, and headlamps still work while your engine is off for your comfort,” Ford noted.

Collins said some people turn off these features on their vehicles, but it’s counterproductive if you want to save money.

“Some people find that annoying – it’s there for a reason. It’s because those cars have to meet energy efficiency standards. … So every time you turn (that feature) off, you’re actually defeating the purpose of saving fuel.”

Collins said he often commutes over a hill, and said there’s many tricks you can use to avoid consuming excess fuel. Gravity can help to be your brake when going up a hill, and going down, other methods can help keep your foot off the accelerator – such as using those other driving modes you may often ignore on the gear shift.

“I have an automatic but I put it in sports mode, which holds it in gear longer. That acts as an engine brake, so I don’t really need to brake on a lot of the corners. I just go through them smoothly, not touching, and my fuel consumption’s on zero.”

Avoiding rush hour can cut back your fuel use. 123RF

And if you can, avoid rush hour

Sitting idling in traffic will waste significant fuel, so – if your job allows it – consider off-peak travel to avoid those long queues, or working from home certain days a week if your employer permits.

Sims said that many of these steps are easy, but changing habits is harder.

“It’s all pretty basic and the science is well understood for cars, trucks, and buses. But to change human behaviour is always the challenge.”

He called for the government to step up fuel conservation messaging.

“What the government needs to do urgently is to run a national education campaign (similar to what was accomplished during Covid times using all media opportunities) to inform drivers how they can save both fuel and money.”
