Protecting Te Tiriti · Evidence Series · Part 05
Where did the “Treaty principles” come from?
The phrase “the principles of the Treaty” is not wording contained in either signed Treaty text. It is a later legal framework. Parliament placed the phrase into statute in 1975; the Waitangi Tribunal then interpreted those principles in claims before it; the Court of Appeal gave them major judicial force in 1987; and the Crown published its own five principles in 1989.

This part does not ask whether particular principles are good or bad policy. It asks a prior question: what is their legal pedigree? The signed texts, statutory phrase “principles”, Tribunal formulations, judicial principles and Crown policy principles must not be treated as though they are the same document.
1. Start with the obvious textual fact
Neither the Māori text nor the English text contains a clause headed “principles of the Treaty”. The signed texts contain a preamble and articles recording substantive commitments. The legal language of principles emerged later.
This matters because a modern reference to “Treaty principles” is already an act of interpretation. It takes the 1840 texts and asks what broader standards should govern present conduct.
2. Parliament put “principles” into law in 1975
The Treaty of Waitangi Act 1975 is the critical statutory starting point. Its preamble does three things together: it records that the English and Māori texts differ; it establishes a Tribunal to deal with the practical application of the principles of the Treaty; and it authorises the Tribunal to determine the Treaty's meaning and effect and whether conduct is inconsistent with those principles.
Section 6 then gives the Tribunal jurisdiction where a claimant says Crown legislation, policy, practice, act or omission is inconsistent with the principles of the Treaty.
The legal category “Treaty principles” was not created by the 1987 Court of Appeal. It was already embedded in the Treaty of Waitangi Act 1975. The courts later gave the phrase substantial justiciable content.
3. Why use principles rather than simply one Treaty text?
The 1975 Act itself records the interpretive problem: the English-language text differs from the Māori-language text. It therefore requires the Tribunal to work with the Treaty as embodied in both texts, determine meaning and effect, and apply its principles to Crown conduct.
The Waitangi Tribunal's current explanation is careful. It says Treaty principles are often derived not only from the strict wording of the two texts but also from the surrounding circumstances in which the Treaty agreement was entered into. It also says there is no single set of principles that every Tribunal panel mechanically applies to every claim.
That is a key distinction. “Principles” are an interpretive bridge. They are not a hidden fourth article waiting inside the document.
4. The Tribunal began developing them case by case
Before the 1987 Lands case, the Waitangi Tribunal had already been interpreting the phrase Parliament gave it. By the early 1980s its reports were rejecting purely literal treatment of the Treaty and looking to the agreement's broader purpose and relationship.
Different Tribunal inquiries have since articulated principles appropriate to the issues before them. Common formulations have included good government, partnership and reciprocity, active protection, rangatiratanga, equity, redress, consultation in appropriate circumstances, and duties that prevent the Crown from avoiding Treaty responsibilities by delegating power elsewhere.
The Tribunal itself cautions against treating those formulations as one closed code. Principles emerge from the Treaty relationship and are applied in context.
5. The 1986 State-Owned Enterprises Act changed the stakes
Section 9 of the State-Owned Enterprises Act 1986 said that nothing in that Act permitted the Crown to act inconsistently with the principles of the Treaty of Waitangi.
That wording mattered because it made Treaty principles a direct statutory control on Crown action under that Act. When major Crown land transfers were proposed, the New Zealand Māori Council challenged them.
6. The 1987 Lands case gave principles major judicial content
In New Zealand Māori Council v Attorney-General, commonly called the Lands case, the Court of Appeal had to decide what section 9 required. Courts of New Zealand describes this as the first significant judicial engagement with Treaty principles.
The Court held that section 9 created justiciable obligations. It developed concepts including an enduring relationship, duties of good faith and reasonableness, active protection, redress, informed decision-making and the Crown's ability to govern subject to Treaty responsibilities.
What the court was interpreting
A statutory command enacted by Parliament: the Crown must not act inconsistently with the principles of the Treaty under the State-Owned Enterprises Act.
What the court was not doing
Amending the signed Treaty texts. It was giving legal meaning to Parliament's statutory use of the word “principles”.
7. “Partnership” is therefore a legal formulation, not an Article heading
The often-used principle of “partnership” is a good example of why categories must be kept separate. The word is not an article heading in Te Tiriti. It became influential through judicial and Tribunal interpretation of the relationship created by the Treaty.
That does not make it fictional. It means its authority is interpretive and jurisprudential rather than being a verbatim term signed in 1840.
Criticising a principle because the exact English word is absent from the Treaty text misses the legal mechanism. But treating a later principle as though rangatira literally signed that formulation in 1840 makes the opposite error.
8. The Crown then created its own five principles in 1989
In July 1989 the fourth Labour Government published Principles for Crown Action on the Treaty of Waitangi. This was the first government statement setting out its own principles to guide Crown decision-making.
| 1989 Crown principle | Summary |
|---|---|
| Kāwanatanga / government | The Government asserted the right to govern and make laws. |
| Rangatiratanga / self-management | Iwi were said to have rights to organise and, under law, control resources they retained. |
| Equality | All New Zealanders are equal before the law. |
| Reasonable cooperation | Government and iwi should cooperate on major issues of common concern. |
| Redress | The Government accepted responsibility for effective processes to resolve grievances and pursue reconciliation. |
Those were Crown policy principles. They were not the only Treaty principles then existing, and they did not become a final statutory code binding all future courts and Tribunals.
9. There has never been one final, universal list
This is where public debate often becomes confused. “The Treaty principles” sounds like a fixed schedule. Official sources do not describe them that way.
The Waitangi Tribunal says each panel determines the principles relevant to the claims before it. Te Ara likewise records that there is no final and complete list. Courts, Tribunal panels, statutes and Crown policy have produced overlapping but not identical formulations.
Te Tiriti and the English Treaty text are signed. Neither contains a provision called “the principles”.
Parliament enacts the Treaty of Waitangi Act and makes consistency with the “principles of the Treaty” the Tribunal's statutory test.
The Tribunal develops principles through claim-specific interpretation of the Treaty texts, purpose and surrounding circumstances.
Section 9 of the State-Owned Enterprises Act prohibits Crown action inconsistent with Treaty principles under that Act.
The Lands case gives the principles major judicial content and confirms that section 9 creates enforceable obligations.
The Crown publishes its own five policy principles for Crown action.
There remains no single final codified list governing every context. The applicable formulation depends on statute, jurisdiction and issue.
10. The finding for this series
The evidence supports a precise conclusion: Treaty principles are a post-1840 legal and interpretive framework, not an additional signed text. Parliament introduced the statutory category in 1975. Tribunal panels, courts and the executive then developed principles for different institutional purposes.
Those principles can create real legal obligations where legislation gives them effect. But their authority, content and decision-maker must always be identified. A Court of Appeal principle, a Tribunal principle, a Crown policy principle and the words of Te Tiriti are related sources, not interchangeable ones.
A call to “protect Treaty principles” may protect important legal restraints on Crown action. But it is not automatically the same proposition as protecting the exact agreement signed in 1840. The next constitutional audit therefore has to ask: who has authority to interpret Te Tiriti and turn it into binding legal standards?
