CHRISTCHURCH — A proposal by South Island tribe Ngāi Tahu to establish an independent Act for freshwater has prompted a political debate over environmental policy and governance roles, as Newsroom reported.
Several hundred people recently gathered in Christchurch at The Piano venue for a debate on freshwater organized by Greenpeace. The event took place in Canterbury against a backdrop of historical regional council dismissals in 2010, expanded agricultural irrigation, and increases in dairy cow approvals.
During the panel discussions, representatives from the Labour, Green, Opportunity, and National parties presented their environmental platforms. Following their panel, expert panellist Gabrielle Huria of Ngāi Tahu freshwater policy unit Te Kura Taka Pini raised the concept of creating a dedicated Act for freshwater. Huria stated that freshwater requires legal recognition outside the standard three-year parliamentary cycle due to its critical role across daily life, power generation, food production, and the general economy.
Huria noted that the proposal remains in a development phase and has not been formally presented to political parties. Ngāi Tahu is currently pausing further progress on the concept to evaluate the water management framework under the Planning and Natural Environment Acts. The tribe previously engaged in an eight-week High Court hearing against the Crown last year regarding freshwater decline, with a judicial decision still pending.
Huria explained that the legal action sought recognition of the tribe's authority, or rangatiratanga, as mana whenua in the South Island, bringing obligations to protect the environment for future generations. She added that primary legislation establishing the fundamental values of water could model elements of the Netherlands water system by using an independent commission to maintain continuity across changing governments, while keeping ultimate parliamentary sovereignty intact.
Te Maire Tau, co-chair of Te Kura Taka Pini and Upoko of Ngāi Tūāhuriri, told Newsroom that the tribe will not actively pursue the legislation until the High Court ruling is released. Tau noted that freshwater currently lacks formal legal status, leaving it vulnerable to misuse. He suggested that water could be vested in itself and symbolically represented by Ngāi Tahu and the Crown in the South Island. Under such a model, an expert commission would establish binding standards for water quality and quantity.
Political parties have offered differing responses to the idea. Green Party environment spokesperson Lan Pham expressed openness to initiatives that prioritize environmental and community health, noting an Act could raise freshwater to a matter of national significance. Labour Party environment spokesperson Rachel Brooking stated her party remains open to discussing ideas with Ngāi Tahu, though Labour's immediate focus involves addressing previous Resource Management Act changes.
Conversely, Act Party spokesperson for energy and resources Simon Court told Newsroom his party opposes the concept. Court stated that appointing Ngāi Tahu and the Crown to represent water would create a co-governance structure. He argued that decision-making over shared natural resources must remain democratically accountable through local councils under the resource management system, rather than giving iwi a separate decision-making role.
Other panellists at the Christchurch event evaluated broader political positions. Public health researcher Marnie Prickett of the University of Otago, Wellington, criticized existing government freshwater policies and expressed concern over environmental exemptions within local resource management frameworks. Eat New Zealand chief executive Angela Clifford called for greater emphasis on local food access during economic downturns, while Greenpeace Aotearoa executive director Russel Norman highlighted policy differences among parties regarding farming input controls and stocking rates.
Additionally, Environmental Defence Society chief operating officer Shay Schlaepfer expressed concern over legislative changes to national freshwater protections, warning that weaker replacement rules should not be permitted given the current state of freshwater environments.
