Protecting Te Tiriti · Evidence Series · Part 08
Entrenched inside whose constitution?
Part 07 established that entrenchment can make a legal rule harder to change. That still leaves the deeper constitutional question unanswered. If Parliament entrenches Te Tiriti through legislation, is Te Tiriti being recognised as an authority that limits Parliament from outside Parliament's own constitutional order, or is Parliament creating a stronger Treaty rule inside the legal system over which Parliament remains the principal law-maker?

This part does not decide what New Zealand's future constitution should be. It asks a narrower question: what constitutional architecture follows from different forms of Treaty entrenchment, and what would have to change before entrenchment could be said to recognise authority outside the ordinary parliamentary model?
1. The present constitutional order is parliamentary
The Cabinet Manual describes New Zealand as a constitutional monarchy, a parliamentary system of government and a democracy. The Constitution Act 1986 is its principal formal constitutional statute. Section 15 states that the Parliament of New Zealand continues to have full power to make laws.
Courts of New Zealand states the orthodox position even more directly: Parliament is sovereign, may create, amend or repeal any law, and the courts do not presently possess a general power to invalidate legislation simply because its substance conflicts with another constitutional value.
If Parliament enacted a Treaty-entrenchment clause tomorrow using the ordinary machinery of the present constitution, the default legal position would be that the clause forms part of that existing parliamentary constitutional order unless the new arrangement expressly changes that architecture.
2. Te Tiriti is already inside the constitutional framework — but not as supreme law
The Cabinet Manual describes Te Tiriti as a founding document of government and an integral part of New Zealand's constitutional framework. It also lists the Treaty as a major source of the constitution and says it may indicate limits in the polity on majority decision-making.
That is significant. The Crown's own constitutional description does not treat Te Tiriti as merely historical. But Part 04 established the legal boundary: current domestic law generally gives Te Tiriti operative effect through statutes, statutory interpretation, judicial review, Tribunal jurisdiction and executive practice rather than treating it as a free-standing supreme law capable by itself of invalidating Acts of Parliament.
Constitutionally inside
Te Tiriti is already recognised as part of the constitutional framework and can constrain or guide public power through recognised legal pathways.
Not constitutionally supreme
Its present status does not generally place the signed text above Parliament with an automatic power to invalidate inconsistent Acts.
3. Ordinary entrenchment would strengthen the shield, not necessarily move the foundation
A Parliament-created 75% or referendum requirement could materially reduce the ability of an ordinary parliamentary majority to amend a Treaty protection. That could be a real constitutional shield.
But unless the design says more, the source of that shield remains legislation enacted within the present system. Parliament chooses the protected wording, the amendment rule and the institutional pathway by which the rule operates.
That is the distinction between protecting Te Tiriti within the constitution and constituting government through Te Tiriti. The first strengthens a rule in an existing architecture. The second asks whether the architecture itself must reflect the allocation of authority between the parties.
4. The Crown's own constitutional account leaves room for more than simple majority rule
The Cabinet Manual contains an important qualification to the parliamentary model. It says constitutional government requires a balance between majority power and minority right and that the answer cannot always lie with simple majority decision-making. It specifically identifies the Treaty among the understandings that can limit how majority authority is exercised.
It goes further. The Manual says that in some situations autonomous Māori institutions have a role within the wider constitutional and political system and that, in other circumstances, the model provided by the Treaty — two parties negotiating and agreeing with one another — is appropriate.
The Crown's own constitutional description therefore recognises a conceptual difference between Māori participation inside ordinary majority government and a two-party model in which agreement between constitutional actors is itself part of the process.
5. The historical evidence makes that distinction unavoidable
For the February 1840 Te Raki signatories examined in Stage 1, the Waitangi Tribunal found that rangatira did not cede their authority to make and enforce law over their people and territories. They agreed instead to share power and authority with the Governor, with different roles and spheres of influence.
Stage 2 later found that the Crown's May 1840 proclamations asserting sovereignty over the North Island were inconsistent with the guarantees of Te Tiriti for those Te Raki rangatira, because the Crown had not explained that it intended to establish a government and legal system under its sole control.
Those findings are geographically and jurisdictionally bounded. They are Tribunal findings, not a judicial declaration that the present Parliament has no legal authority throughout New Zealand. But they are directly relevant to the design question: a constitutional model based solely on unilateral parliamentary control is not the only model appearing in the historical Treaty record.
6. Four different things can hide behind the phrase “entrench Te Tiriti”
| Model | What it does | Where authority remains |
|---|---|---|
| Parliamentary shield | Parliament protects a Treaty clause with a supermajority or referendum requirement. | Primarily within the existing parliamentary constitutional order. |
| Dual-consent protection | Amendment requires both parliamentary approval and consent from a defined Māori or hapū constitutional authority. | Moves amendment authority beyond Parliament acting alone, if the mechanism is legally effective. |
| Higher-law model | An entrenched constitutional text is given priority over inconsistent ordinary legislation, potentially with judicial remedies. | Depends on who authors the higher law, who may amend it and who interprets it. |
| Shared-authority architecture | Different institutions or spheres of decision-making are constitutionally allocated between kāwanatanga and rangatiratanga, with agreed mechanisms for overlap. | Authority is structurally distributed rather than merely protected by a parliamentary veto rule. |
These are analytical models, not statements of current New Zealand law. They illustrate why the word “entrenchment” by itself is too imprecise to tell us what constitutional relationship is being proposed.
7. A consent requirement would need an actual constitutional actor
If amendment were to require the consent of “the other Treaty party”, legislation would have to answer a difficult institutional question: who possesses authority to give or withhold that consent today?
Would it be iwi organisations, hapū, rangatira, Māori electors, a national Māori assembly, existing Māori constitutional bodies, or some other structure? Those are not interchangeable. A Crown-created representative body would also raise the question of whether the Crown had selected the very institution meant to constrain Crown authority.
A dual-consent clause is not constitutionally complete until the identity, mandate, selection method, scope of authority and accountability of the non-Parliamentary decision-maker are defined.
8. Entrenchment alone does not restore an earlier jurisdiction
It would be an error to assume that entrenching Te Tiriti automatically revives every form of hapū authority that existed before 1840. A statutory lock can constrain amendment without transferring legislative, adjudicative, territorial or executive powers to hapū.
The reverse error is also possible. The fact that a Treaty protection is enacted by Parliament does not automatically make it meaningless or prove that rangatiratanga has been extinguished. The legal effect depends on the actual architecture created.
What entrenchment can do
Make unilateral legal change harder, require broader agreement, stabilise rights or institutions, and potentially create enforceable constitutional procedures.
What it cannot do by implication
Prove a historical cession, restore pre-1840 jurisdiction, identify the modern Treaty parties, allocate governing spheres, or decide who has final interpretive authority.
9. The real drafting questions are constitutional, not symbolic
Any serious proposal to entrench Te Tiriti should therefore answer at least these questions:
| Question | Constitutional consequence |
|---|---|
| Who creates the protection? | Parliament alone, a referendum, negotiated agreement, or a constituent process? |
| Who must consent to change? | A parliamentary supermajority, the electorate, hapū or Māori constitutional institutions, or some combination? |
| Who interprets it? | Existing courts, the Waitangi Tribunal, a new constitutional body, the parties jointly, or different institutions in different spheres? |
| What happens on conflict? | Interpretation only, declaration of inconsistency, invalidity of legislation, mandatory negotiation, or another remedy? |
| What authority remains outside Parliament? | If the answer is “none”, the arrangement is principally a strengthened parliamentary Treaty protection. If independent authority is recognised, its jurisdiction must be stated. |
10. The finding for this series
The evidence supports a disciplined conclusion: under the present constitutional order, parliamentary entrenchment of Te Tiriti would ordinarily place stronger Treaty protection inside New Zealand's existing parliamentary constitution. That could be constitutionally important and materially constrain ordinary majorities, but it would not by itself establish that constitutional authority is jointly sourced from Parliament and rangatira.
To move beyond a parliamentary shield, the constitutional design would have to say what authority exists independently of Parliament, who exercises it, how the parties must agree, how overlapping jurisdiction is resolved, and what legal consequence follows when one side acts without the required authority.
The question is no longer simply whether Te Tiriti should be harder to repeal. It is whether the protection preserves tino rangatiratanga as an operative authority, or protects Treaty rights and principles inside a system in which Parliament remains the dominant constitutional law-maker. That is the next audit.
