‘Only A Matter Of Time' Before A Baby Is Harmed Due To Nitrate Contamination, Warns Greenpeace
This is the second town to make headlines by exceeding nitrate levels in the town water supply in the last year, with Canterbury's Glenavy township exceeding the MAV (maximum allowable value) in December last year. The MAV was set in the 1960s to prevent methemoglobinemia, or Blue Baby Syndrome, which can be fatal.
Greenpeace spokesperson Will Appelbe says "It's only a matter of time before we see a baby harmed in New Zealand due to consuming formula mixed with nitrate contaminated water. It is absolutely unacceptable that rural communities are unable to drink the water coming out of their kitchen tap - and this is happening more and more frequently."
"The main source of this contamination is the intensive dairy industry - in particular, the overuse of synthetic nitrogen fertiliser. To avoid the risk to life that is posed by nitrate contamination, we need to stop the pollution at the source, and that means implementing a sinking cap on the use of synthetic nitrogen fertiliser.

"However, the Luxon Government is doing the opposite. Rather than changing our laws to protect freshwater, Chris Bishop is implementing a freshwater pollution plan. He is weakening the national direction on freshwater, and removing the cap on synthetic nitrogen fertiliser use.
"We know that the use of synthetic nitrogen fertiliser is causing nitrate contamination, and already towns in rural areas like Canterbury and Southland are facing the consequences of this, with undrinkable water. Removing limits on fertiliser use will worsen the drinking water crisis - and it's only a matter of time before it proves to be dangerous."
There are several health risks associated with nitrate levels much lower than the current maximum allowable value of 11.3 mg/L. Long term exposure to nitrate contaminated water above 1 mg/L has been linked to an increased risk of bowel cancer. At levels above 5 mg/L, the New Zealand College of Midwives recommends that pregnant people consider finding another source of water, due to an increased risk of preterm birth.
Gore's water supply tested at 11.4 mg/L of nitrate on Friday. Nitrate cannot be removed by boiling drinking water, so those with high levels of nitrate must find an alternative water source or invest in costly reverse osmosis filters.
Greenpeace says that the best way to reduce harm done by nitrate pollution in the long-term is to regulate the source of the pollution.
"We're calling on this Government to make decisions that will protect rural communities' access to safe drinking water, and prevent the health impacts that are known to arise from nitrate contamination," says Appelbe.
"New Zealanders overwhelmingly want clean water in lakes, rivers, and their kitchen taps - it's time for Luxon to deliver."

New PHANZ Policy Affirms The Importance Of Community Water Fluoridation
The Public Health Association of New Zealand (PHANZ) supports community water fluoridation as a critical public health measure and supports the Government continuing to uphold its responsibility for implementing community water fluoridation. Releasing its new policy position statement on Community Water Fluoridation, the PHANZ emphasises the strong body of international and national evidence supporting community water fluoridation as a safe and effective public health measure for preventing tooth decay in both children and adults. 'Fluoridated water protects our mokopuna, whānau and communities who might face barriers in accessing dental care' says Dr Cadence Kaumoana, Chief Executive. 'It is a simple, safe, proven and equitable approach to improve the oral health of all people in Aotearoa New Zealand.' In Aotearoa New Zealand, tooth decay is one of the leading causes of hospital admissions for children aged 0-14 years. In 2019, there were 9,267 dental and hospital events, equating to 4.6% of all children's hospital events, and tooth decay was the most common principal diagnosis (7,161 children) from all children's hospital events.[1]For adults (aged 15 years and over), 45.0% have had one or more teeth removed in their lifetime due to tooth decay, with increased prevalence for Māori (50.3%) and people with disabilities (64.4%).2 Until relatively recently, the decision to fluoridate water supplies was determined at a local authority level. However, the introduction of the Health (Fluoridation of Drinking Water) Amendment Act 2021[ 3] enabled the Director-General of Health to direct local authorities to fluoridate drinking water supplies, creating a nationally consistent, health-focused, and evidence-based decision-making process for community water fluoridation in Aotearoa New Zealand. In July 2022, the Director-General of Health issued directions to 14 local authorities to take practicable steps (with support from the Ministry of Health) to ensure their drinking water supplies contained optimal level of fluoride.[4] As a result of the directions to these 14 local authorities, around 400,000 more people have gained access to fluoridated community drinking water.[5] The PHANZ notes that despite the overwhelming evidence for community water fluoridation, and the public health benefits of centralising decision-making under the Director-General of Health, opposition to this approach persists. In February 2025, a Member's Bill from New Zealand First proposed repealing the Health (Fluoridation of Drinking Water) Amendment Act 2021.[6] Repealing this would return responsibility for fluoridation to local authorities, a system that previously led to regional inconsistencies and allowed misinformation and non-evidenced-based decisions to compromise oral health outcomes. In response to this announcement, the Health Minister reaffirmed that the Government would maintain its current fluoride policy.7 'Oral health isn't just about teeth — it's about dignity, confidence, and basic quality of life,' says Dr Kaumoana. 'We support the Government's commitment to keep community water fluoridation at the national level. Every whānau deserves access to safe and effective oral health protection regardless of their location. This is a simple, proven way to prevent harm and reduce health inequities.' The PHANZ also recognises that oral health is shaped by a broad range of social determinants. While our recent statement focuses on community water fluoridation, it should be understood within the wider oral health context in Aotearoa New Zealand, including the impacts of childhood poverty, food insecurity, unhealthy food environments, and the unmet demand, and barriers to access, for oral health care across the health system. Improving oral health in Aotearoa New Zealand requires coordinated, cross-sector action, of which community water fluoridation is an important component. • Read the full PHANZ policy position statement: PHANZ Policy Position Statement on Community Water Fluoridation • Watch the PHANZ policy webinar supporting the release of the policy position statement. This webinar includes a brief overview of the policy position statement, followed by a presentation from oral health expert and PHANZ member Heuiwon (Chris) Han.

Lobbying Docs Show Govt's Weakness
Today's revelations of tobacco industry lobbying lay bare why Labour's Tobacco Transparency Bill is needed to stop governments putting the interests of the industry above people's health. Today's RNZ story shows the wide range of politicians, experts, and officials tobacco lobbyists Philip Morris targeted to influence regulations and garner support for their products, including targeting Winston Peters. 'Christopher Luxon's weak leadership has allowed Winston Peters and the tobacco industry ride roughshod over him by agreeing to a $200 million tax break for the tobacco industry,' Labour health spokesperson Ayesha Verrall said. 'Philip Morris even wrote legislation for NZ First to loosen the regulations around vaping. They note that Winston Peters is 'industry friendly and highly geared towards commercial interests in the sector. 'I launched a members' bill earlier this year to require disclosure of government contact with the tobacco industry, to make sure industry efforts to undermine New Zealanders' health are reported,' Ayesha Verrall said. The documents revealed today also show how vaping company JUUL targeted New Zealand as a market. 'It's gutting to think we might not have the youth vaping problem we have today if my Bill was in place in 2018 before any of this lobbying took place. 'Around the world, tobacco companies have a long history of influencing and weakening health policies to better suit their bottom line – and here we see evidence of it happening in New Zealand. 'It's time we get rid of the smokescreen and protect Kiwis from big tobacco's lobbying tactics – they have no place in health policy,' Ayesha Verrall said.

Gore's Iconic Brown Trout Statue Latest Victim Of Township's Drinking Water Crisis
Gore's brown trout statue has become the latest victim of dairy industry pollution. On Tuesday night, the iconic statue was given cartoon-style crosses for eyes - Greenpeace Aotearoa's way of spotlighting the town's drinking water crisis and the role of dairy pollution in poisoning it. Greenpeace has also rebranded the 'Welcome to Gore' sign, which now reads 'Welcome to Gore - where dirty dairy wrecked the water'. Last Friday, residents of Gore were issued a do-not-drink notice after their town water supply exceeded 11.3 mg/L of nitrate, which is the legal limit set in the 1950s to avoid blue baby syndrome. While this notice has since been lifted, Greenpeace warns that it is only a matter of time before this happens again. Greenpeace spokesperson Will Appelbe says "The dirty dairy industry has wrecked Gore's drinking water, putting people's health at risk due to nitrate contamination. It is unacceptable that this community is increasingly unable to drink the water coming out of their kitchen taps. Gore's giant brown trout statue is now a beacon of the industry's pollution of drinking water." A growing body of scientific evidence has linked several health risks with long term exposure to nitrate at levels below the current legal limits. Long-term exposure to nitrate in drinking water at levels as low as 1 mg/L has been linked to an increased risk of bowel cancer, and this risk increases with higher levels of nitrate. At levels of nitrate above 5 mg/L, the New Zealand College of Midwives advises pregnant people to consider an alternative source of drinking water, because of an increased risk of preterm birth. Appelbe says, " Two years ago, we offered free nitrate tests to Gore residents, and found that 45% of the samples we tested from the town supply were above 4 mg/L of nitrate. Since then, levels of nitrate contamination have more than doubled, to above 10 mg/L. "This problem isn't going to go away simply by diluting the water - for many rural communities, nitrate contamination will get worse unless action is taken to address the source of the pollution: the intensive dairy industry, led by Fonterra. "There are too many cows and the industry is using too much synthetic nitrogen fertiliser. Nitrate contamination across the country is increasing as a result, particularly in rural areas. "We need regional councils and the Government to take action now. But instead of protecting people's drinking water, Luxon's Government is attempting to weaken freshwater protections. They've proposed removing the cap on synthetic nitrogen fertiliser, which will enable dairy expansion. That means more cows, more fertiliser, and ultimately more contaminated drinking water." Greenpeace is calling on the Government to scrap its proposed changes to the National Policy Statement on Freshwater Management and the National Environmental Standards for Freshwater, which are currently going through consultation. The organisation says that these changes will make freshwater pollution worse, impacting lakes, rivers, and drinking water across the country.
