Freshwater Is A Public Health Issue – New PHANZ Policy Calls For Action
Releasing its new policy position statement on Freshwater and Health, the PHANZ emphasises the important relationship between freshwater and health, and the need for a strong health and equity-focused approach to freshwater policy and management that upholds Te Tiriti o Waitangi and strengthens environmental protections.
'Healthy freshwater and functioning ecosystems are critical for healthy, stable communities' says Dr Cadence Kaumoana, Chief Executive. 'When our waterways are polluted, it impacts everything – from drinking water and food safety to mental health and climate resilience.'
The PHANZ statement acknowledges that the quality of drinking water and the ecological health of waterways in Aotearoa New Zealand are under increasing pressure from intensified agricultural systems, poor infrastructure, and climate change. The PHANZ notes the public health risks linked to groundwater contamination and rising nitrate levels, and affirms that access to safe, good quality drinking water is a fundamental human right essential to health and wellbeing.
The PHANZ strongly supports the Te Mana o Te Wai framework, which is the current decision-making framework for freshwater management in Aotearoa New Zealand. Te Mana o te Wai safeguards the health of freshwater ecosystems and explicitly requires access to safe, good quality drinking water.
'We need a public health approach to be a key part of freshwater policy', says Dr Kaumoana. 'This means ensuring Te Mana o Te Wai remains a core component of freshwater policy, prioritising the health of freshwater ecosystems and the health of people, ahead of commercial and other polluting interests.'
The PHANZ's policy position statement comes as the Government is undertaking consultation on proposed changes to Aotearoa New Zealand's Freshwater National Direction. While the proposed changes focus on 'cutting red tape' for commercial entities, experts note that it will mean more pollution in the places we swim, fish, and in communities' drinking water sources.
The PHANZ is supporting the public health sector, and the general public, to speak up for a strong public-health approach to freshwater management. The PHANZ has produced a 2-page guidance document, which provides an overview of what is being proposed in the government's consultation, outlines why this is an important issue for public health, and how to make a submission.

Patient-Focused New Zealand Health Plan Tabled
Minister of Health Health New Zealand's New Zealand Health Plan was tabled in Parliament this afternoon. Developed by Health New Zealand, the plan is a requirement under the Pae Ora (Healthy Futures) Act 2022. 'The plan outlines how Health New Zealand will deliver on the Government's health priorities over the period 2024–2027,' Health Minister Simeon Brown says. 'It sets the direction for how we will improve health outcomes and ensure all New Zealanders can access the care they need, where and when they need it. 'It gives effect to the Government Policy Statement on Health 2024–2027, with a clear focus on the Government's five health targets and five mental health targets: Health targets: faster cancer treatment improved childhood immunisation shorter stays in emergency departments shorter wait times for first specialist assessments shorter wait times for elective treatment. Mental health and addiction targets: faster access to specialist mental health and addiction services faster access to primary mental health and addiction services shorter mental health and addiction related stays in emergency departments increased mental health and addiction workforce development strengthened focus on prevention and early intervention. 'The plan is focused on achieving the Government's health targets, ensuring the health system delivers real results for patients and communities. These targets are backed by clear accountability and transparent reporting, so the public can track progress on a regular basis. 'Reducing wait times is a key priority for the Government. Too many New Zealanders have been left waiting far too long for the care they need. Under the last Government, waitlists ballooned – with the number of Kiwis waiting more than four months for elective procedures like hip, knee, or cataract surgeries increasing by over 2,500 per cent. 'Health New Zealand is focussed on delivering the Elective Boost programme, which will deliver 21,000 additional procedures over the 2025/2026 year to help clear the backlog of patients needing care.' The plan also sets out how the Government will grow and support the health workforce; improve clinical leadership with continuous quality improvement and innovation; invest in essential hospital infrastructure; ensure services are delivered more consistently across the country; and strengthen primary care across New Zealand so that people can receive timely, quality care in the community. 'Our focus is clear: putting patients back at the centre of the health system. We're building a system that delivers real results, and this plan is a key part of that,' Mr Brown says. Note:

Gisborne targets youth vaping with CBD smoke-free policy
However, some councillors questioned whether it was a matter for the council or a public health issue for the central Government to address. 'It's a health problem. I worry we're dipping into things that we shouldn't be,' said councillor Debbie Gregory. Councillor Rawinia Parata responded that policies like these only made kids hide their smoking. In contrast, councillor Colin Alder said central Government had let them down. As an ex-smoker who battled an addiction for most of his life, Alder said he would love all the money he spent on smoking back 'with interest'. 'The companies that have been peddling this addiction are rubbing their hands together.' According to the meeting's report, Tairāwhiti continued to have the highest smoking rates in the country. However, data showed it was decreasing, with the rate of smoking dropping from 22% to 12% between 2018 and 2023, the report said. Action for Smokefree 2025 (Ash NZ) surveys thousands of Year 10 students every year on smoking and vaping behaviour habits. In 2023, the National Public Health Services prepared a report for the Gisborne District Council using Ash NZ data to understand the extent of vaping in the region. The percentage of participating Gisborne students who regularly vape soared from 1.6% in 2015 to 36% in 2022, but had decreased to 26.6% in 2023. The number of students who had tried vaping at least once had increased from a quarter in 2015 to just over half (54.7%) in 2023. The Māori rate of regular vaping (37.0%) was significantly higher than the rate for European/other (14.4%), according to the report. Councillor Nick Tupara agreed it was a government responsibility and a public health issue, particularly for Māori. However, the council could not expect national change if there was no voice locally. 'Looking at the data, it is epidemic, and it was during my mother's time and my grandmother's time.' Councillor Teddy Thompson said New Zealand was behind the eight ball, noting that in Australia, vape flavours were limited and people could only buy vapes from pharmacies. He and Gregory asked for the cost of updating signage, while councillor Larry Foster wanted to expand the policy area to include the central business district. The policy's designated smoke-free areas are playgrounds, parks, sports grounds, beaches, and outdoor public areas around council buildings and facilities, as well as any events run or funded by the council. Strategic planning manager Charlotte Knight said that as the policy was a position statement rather than an enforceable rule, it did not require consultation. After the majority of councillors voted in favour of Foster's suggestion, Knight said the council would include the CBD, and the area would be the same as the Local Alcohol Policy definition. A council spokeswoman said the cost to update the policy was minimal. There might be some funding from the Ministry of Health and other stakeholders to help with updating signage, she said. Mayor Rehette Stoltz recalled how, in 2018, the council questioned how it would enforce its initial smoking policy. 'The community self-police. At the end of the day, people slowly stop smoking in places that they used to, and now people just don't.' Stoltz said the policy was 'more a signal from the council to the community on what we value in our open spaces for our children'. 'Let's send that message and make it supportive. It is a health issue, there is help available, and not to shame people,' she said. According to the council report, no council in New Zealand had a smoke-free/vape-free bylaw. The Whanganui District Council did adopt a bylaw. However, it revoked it because of enforcement issues and now used a voluntary policy, the report said. The council will update its website by September 1 to communicate the policy changes.

Scientists create a new online calculator that reveals your heart's age and your risk of heart disease
New ways of assessing heart health The idea of using health data to assess your risk of developing heart disease is hardly new, of course. The Framingham Risk Score, which uses various health metrics to predict your 10-year likelihood of developing heart disease, has been around for decades. More recently, the American Heart Association developed the Predicting Risk of Cardiovascular Disease Events (Prevent) equations, which use new data about the health of tens of thousands of American adults, beginning at age 30, to predict heart disease risk. Khan was the lead author of the 2023 study that laid out the Prevent equations. But she's also a clinician and knew from talking to patients that 'it's really hard to understand what a 10% risk' of developing heart disease in the near future 'means for you'. And she's a researcher who's studied longevity among the Amish and was interested in the differences between biological and chronological age, and why people born in the same year can seem to age quite differently. Those interests converged when she began wondering if she could reinterpret the Prevent equations into a framework that would be more intuitive for most people, telling them, in effect, if their hearts are ageing too fast. The study found most Americans have hearts older than their chronological age, with men averaging seven years older. Photo / 123rf Most Americans' hearts are older than they are So, she and her colleagues used the Prevent data to figure out benchmarks for optimal heart health markers, such as blood pressure and blood sugar, among men and women at every age from 30 to 79. These would set the underpinnings of the heart-age test. (Most of the metrics used in the calculator are standard, but some are more specialised, such as an eGFR, which tests kidney function.) Then, since they were interested in the state of heart health in America, they checked the heart ages of more than 14,000 men and women enrolled in the Government's huge and ongoing National Health and Nutrition Examination Survey. Most of them turned out to have hearts older than their biological age. Men, on average, had heart ages about seven years older than their chronological age, while women's hearts were about four years older than their birth years. The gulfs between actual and biological heart ages were largest among people, especially men, with a high school education or less and those who identified as black or Hispanic. But even many people in their 30s had relatively old hearts. What to do about an ageing heart What does it mean if the calculator says your heart is older than you? 'First, it's important to have context,' Khan said. 'A year's difference from your chronological age is probably not meaningful. But if people's hearts are more than five years or 10 years away from their chronological age, it's worth paying attention to what's going on and what might be driving that.' Talk to your doctor if your heart age is at least five years older than your calendar age, she said. The calculator might be indicating you'd benefit from more vigilance. 'We know that half of people with high blood pressure aren't being treated,' she said, 'and most people who qualify for statin therapy aren't on it.' The interventions needn't all be medical. 'Lifestyle changes, especially exercise and diet, are also important,' she said. Even people whose heart ages equal or prove younger than their actual age can benefit from that knowledge, she said. 'One of the most challenging things is to maintain healthy ageing.' So, as the years pass or you enter health transitions, such as menopause, the calculator might be able to help you track how well your heart continues to age. The study suggests that if your heart age is over five years older, consult a doctor and consider lifestyle changes. What the calculator leaves out The heart-age calculator has limits, though. 'It's a way to communicate risk that will resonate with some people,' said Martha Gulati, the director of preventive cardiology and associate director of the Barbra Streisand Women's Heart Centre at Cedars-Sinai Health Sciences University in Los Angeles. But its equations don't include certain cardiovascular risk factors specific to women, she said, such as menopausal changes and pregnancy complications. They also don't include estimations of aerobic fitness or exercise habits, which can be key to heart health, said Ulrik Wisloff, the head of the cardiac exercise research group at the Norwegian University of Science and Technology in Trondheim, Norway, who's studied exercise and longevity for decades. 'I still find it puzzling why physical activity and peak oxygen uptake have yet to be incorporated into the original Framingham risk model, despite strong evidence' for their predictive power, he said. His group has developed its own free, online calculator, based on exercise and endurance, that estimates your fitness age in comparison with your chronological age. The key point about all of these biological-age calculators, whether they focus on fitness or organs, such as hearts, is that they can serve as a wake-up call, Gulati said. If the numbers indicate your heart might be ageing too rapidly, that's a message that you probably need to be paying some more attention to your health. 'I do think' the heart-age calculator 'is a bit gimmicky,' Gulati said. 'But if it helps to motivate a patient to make changes, I'm here for it.'
