Geoff Parker: Constitutional Transformation or Constitutional Drift?

The push for constitutional change through Matike Mai Aotearoa is often framed as a reasonable evolution — a move toward “partnership” grounded in the Treaty of Waitangi. Many of its advocates present it as a balanced and inclusive vision for New Zealand’s future.

But the issue is not intent. It is direction — and how key concepts are being reinterpreted to justify structural change.

A key point often overlooked is that the Treaty’s role in New Zealand’s legal and political system is largely a modern development. Its practical force expanded significantly after the establishment of the Waitangi Tribunal in 1975, and through later court decisions such as New Zealand Māori Council v Attorney-General (1987).

That context matters. It shows that what is now being used as a basis for constitutional transformation is not a continuously applied constitutional framework since 1840, but a body of evolving interpretation.

Central to this debate are the meanings of tino rangatiratanga and kāwanatanga. These terms are often presented today as if they establish a form of dual or parallel sovereignty between Māori and the Crown.

However, their meaning cannot be separated from their constitutional context.

In 1835, Declaration of the Independence of New Zealand affirmed the authority of rangatira within a framework of independent tribal governance. In that setting, any notion of “governance” sat alongside — not above — chiefly authority.

By contrast, the Treaty of Waitangi was a different kind of document altogether. The English text explicitly records a transfer of sovereignty to the Crown. The Māori text uses kāwanatanga, a transliteration of “governorship,” but within a fundamentally different constitutional setting — one that resulted in a single, unified system of government across the country.

This distinction matters. Words do not operate in isolation; they operate within structures. Whatever the linguistic debate, the functional outcome was clear: New Zealand developed as a unitary state, with one system of law and governance.

Modern arguments increasingly reinterpret tino rangatiratanga as a form of ongoing, parallel sovereignty. But that interpretation depends on reading these terms in a way that is detached from both their original context and their constitutional effect.

If kāwanatanga is now said to mean something less than full governing authority, then a basic question arises: where, in practical terms, does ultimate decision-making power sit?

A constitution cannot rely on unresolved ambiguity. It must clearly define who makes decisions, how conflicts are resolved, and how accountability is maintained. The Matike Mai framework does not adequately do this. Instead, it proposes parallel spheres of authority without clearly explaining how disagreements are settled or how consistent national governance is maintained.

Supporters frequently point to extensive consultation as evidence of legitimacy. But consultation is not the same as democratic consent. Engagement within Māori communities is entirely appropriate for developing Māori perspectives — but a constitutional system governs everyone. It therefore requires broad agreement across the whole population.

The argument is often reinforced through alignment with He Puapua and international standards promoted by the United Nations. However, these frameworks are not binding constitutional models. They are aspirational guidelines that must be interpreted within each country’s democratic system. Treating them as a direct blueprint for restructuring sovereignty stretches their intended role.

Examples such as Māori-led Covid checkpoints are sometimes presented as evidence that separate spheres of authority can work in practice. But emergency responses during a crisis are not proof of long-term constitutional viability. Temporary, localised actions — often operating in legal grey areas — are not a substitute for stable, nationwide governance.

This brings the issue back to first principles: how political power is allocated.

Modern democratic systems are built on equal individual political rights — one person, one political standing — that each citizen has the same standing in how they are governed. Any model that introduces differentiated authority based on ancestry, even when framed as “partnership,” raises difficult questions about how that principle is maintained in practice.

This is why incremental change matters. Individual steps may appear limited, but once embedded, they can shift the direction of the system over time. Constitutional change does not always happen in one moment — it can develop gradually, without a clear point of public consent.

None of this means New Zealand’s system is beyond improvement. There are legitimate debates about how to recognise the Treaty, improve outcomes, and strengthen accountability. But those are arguments for careful reform — not for adopting a model that depends on contested interpretations of key terms and leaves core questions unresolved.

A durable constitutional system requires clarity of authority, equal citizenship, and broad public consent. At present, the Matike Mai vision does not convincingly provide them.

Good intentions are not enough. When foundational terms are reinterpreted to support far-reaching structural change, scrutiny is not only justified — it is necessary.
