Safe Drinking Water is a Shared Responsibility

Meaningful change does not always begin with major infrastructure or sweeping reform. Sometimes it begins by giving communities the trust, tools, resources, and opportunity to protect the water they have always cared for.
We expect clean water to flow every time we turn on a tap, trusting that someone
has already done the work to keep it safe. But across Aotearoa-New Zealand, not every community has benefited equally from the systems designed to protect public health.
While municipalities in Aotearoa-New Zealand are generally supported by established monitoring programmes and ongoing investment, many marae (traditional communal areas) and rural drinking water supplies have spent years operating with far less attention and support due to systemic inequalities.
This raises an important question: what hazards remain unseen when communities themselves are overlooked? A recent Māori-led (Indigenous-led) research programme offers a new way forward.
Rather than ensuring communities adapt to existing systems, the partnership placed Ngāi Tahu-the principal iwi (tribe) of Te Waipounamu (New Zealand’s South Island)-at the centre of drinking water safety. Over twelve months, 27 Māngai Wai Māori (water champions) from 16 communities were enabled to monitor their own drinking water supplies across the takiwā (tribal boundary), building local capability while combining community leadership with scientific expertise.
The programme was never simply about collecting more data. It was about ensuring that the communities who depend on these water supplies were equipped with the knowledge, resources, and support to understand and protect their drinking water.
Through the initiative, six drinking water supplies with microbial water quality concerns were identified and addressed. These were not newly created problems; they were existing challenges that could have remained unidentified without dedicated monitoring focused on communities that have historically received less support.
For the whānau (families) who rely on these water supplies every day, the value of this work cannot be measured only by laboratory results. It is measured in confidence: in knowing that the water shared at marae, used to prepare kai (food), and to manaaki (extend care and hospitality to) guests has been better understood and made safer.
The approach also challenged a long-standing assumption that protecting drinking water is solely the responsibility of distant institutions. By investing in Indigenous capability, supporting Māngai Wai Māori, and combining mātauranga Māori (Māori knowledge) with advanced water science, the programme strengthened both local knowledge and public health outcomes.
Scientific testing remained essential, but its greatest impact came because it was placed in the hands of the people with the deepest connection to the water and the strongest commitment to protecting it.
Many marae, papakāinga (Māori community), and other rural community drinking water supplies across Aotearoa-New Zealand face similar challenges. Limited resources, ageing infrastructure, and historical underinvestment can mean that important drinking water quality issues are unlikely to receive the same level of attention afforded to larger public supplies. As climate change places increasing pressure on these freshwater systems, ensuring communities are not left behind has become even more important.
The lesson from this research is not that communities should replace water professionals or regulators. It is that better outcomes are achieved when Indigenous communities are recognised as partners rather than passive recipients of water services.
As local and international actors continue to advance progress on Sustainable Development Goal 6 and shape the future of drinking water, investment should not be measured only in treatment plants, pipes, wells, and compliance. It should also be measured in people—in the knowledge they hold, the leadership they provide, and the trust they can build within their own communities.
Safe drinking water begins long before someone turns on the tap. It begins with communities that are trusted to care for the water that sustains them—ki uta ki tai, from the mountains to the sea.
Protecting drinking water is not only about delivering water to communities. It is about ensuring every community has the opportunity, knowledge, and support to make its water safer. Safe drinking water is a shared responsibility.
