A new bill introduced in the Cook Islands is set to mark the first time a Māori tribe will influence how the House of Ariki should be governed.
The Ngamaru Ariki Incorporation Bill 2026 would be the Pacific nation's first piece of legislation to formally give effect to resolutions for its council of chiefs.
Parliamentary clerk Tangata Vainerere said while the Cook Islands has long recognised the importance of traditional leadership, the piece of legislation marks the first time the Indigenous Kūki 'Airani people have brought forward their own centuries-old Māori lores.
The bill forms a response to calls from the House of Ariki for traditional title disputes to only be resolved according to "customary rules," rather than through the common-law court process.
The house, a traditional advisory body to parliament, is composed of hereditary Cook Islands Māori chiefs, but does not function as a formal legislative chamber of the parliament and cannot pass laws.
Mr Vainerere said in the nation's unicameral parliament sitting, "a historic step will be taken, one that may redefine how the Cook Islands balances its modern legal system against its deep cultural foundations".
He explained that in 2024 and again in 2025, the House of Ariki representing the highest chiefly authority called for a new approach to resolving disputes over traditional titles.
"For many years, these disputes have been taken to the (law) courts under existing legislation," Mr Vainerere said.
"While courts have sought to apply customary principles, concern has grown that such matters are better resolved within the structures of tradition itself."
The clerk, who stands as a chief procedural adviser to parliament responsible for parliamentary administration, records, and advice on legislative procedures, said the House of Ariki responded by calling on each title to develop its own framework for succession, based on its own custom, before bringing it to the parliamentary chamber.
"The Ngamaru Ariki Incorporation Bill is the first to answer that call," Mr Vainerere said.
He believed at its core, the bill does not attempt to change custom; instead, it seeks to "recognise it properly in law".
Mr Vainerere said the bill provides a framework confirming the succession to the Ngamaru Ariki title — a hereditary (high chief) title, associated with the Ngāti Te Akatauira people as one of the traditional chiefly titles across the island of Atiu — which is determined in accordance with akonoanga tupuna, the traditional knowledge, customs, beliefs, values, and practices of their ancestors.
The bill will also clarify the roles of traditional authorities, including the Kōpū Ariki's customary bodies, while ensuring future disputes are resolved within the tribe's own decision-making processes and limiting the role of the courts to a supervisory function to ensure fairness without determining outcomes.
It incorporates the Office of Ngamaru Ariki as a legal entity, and recognises the lands, insignia, and taonga (treasure) associated with the title.
Mr Vainerere acknowledged the bill represents new parliamentary and cultural ground for the Polynesian island society which has existed for around 1500 years.
"This has not been attempted before," he said. "This is the first time a tribe has stepped forward to put its custom into a form that parliament can recognise in law.
"Because of this, the bill has naturally generated questions, discussion, and differing views which is part of the process.
"People care deeply about identity, genealogy, and leadership.
"That is not something we should be afraid of, but it must be approached in the right way."
Mr Vainerere said a key point of the bill is that it does not replace tradition with legislation, but in fact does the opposite.
It recognises traditional systems already exist and ensures they are respected within the national legal framework.
The bill is designed so custom remains the source of authority, and the law gives it an effect to that authority rather than overriding it.
"If passed, the Ngamaru Ariki Incorporation Bill is expected to become a model, not in content, but in approach." Mr Vainerere added.
"Each Ariki title across the islands has its own history, its own genealogy and its own processes.
"The intention is not uniformity, but self-definition.
"This bill does not say how other titles must do things - it shows that it is possible for each title to define its own pathway."
Mr Vainerere said for a modern state to recognise and uphold cultural foundations without losing their traditions, the Ngamaru Ariki Incorporation Bill offers to allow "custom and law to work together rather than in competition".
"It is about how a nation standing at the crossroad where tradition meets modernity, honours its past while shaping its future," he said.
The House of Ariki was established shortly after the Cook Islands became a self-governing state from 1965 with free association of Aotearoa/New Zealand to give hereditary chiefs a formal role in a modern political system.
