What does the Constitution Act 1986 actually do?
The Act consolidates today's core constitutional machinery, declares the Sovereign in right of New Zealand the head of state, and expressly continues the Parliament descended from the 1852 General Assembly.
Present constitutional structure
The Constitution Act 1986 received assent on 13 December 1986 and came into force on 1 January 1987. It is one of the central statutes in New Zealand's present constitutional arrangements.
Section 2 identifies the “Sovereign in right of New Zealand” as the head of state. Section 14 provides for a Parliament consisting of that Sovereign and the House of Representatives. Section 14(2) expressly says this Parliament is the same body as the General Assembly established under the United Kingdom's New Zealand Constitution Act 1852.
Section 15 continues Parliament's full power to make laws. Section 26 provides for specified United Kingdom constitutional enactments to cease having effect as part of New Zealand law.
This is why there is no obvious “break” in the domestic legal genealogy. The modern institutions are not pretending to be unrelated successors. The statute itself records continuity.
But the Act is also not a new foundational compact with hapū. It does not say that Māori have now ceded the authority that the Waitangi Tribunal found the February Te Raki signatories retained. It operates within the legal system whose institutional ancestry the Act itself identifies.
This produces the central distinction for the series: a legal order can have strong internal continuity even while the historical justification for its first acquisition of authority remains contested.
The Constitution Act 1986 is a strong answer to “what is the present legal machinery?” It is not, by itself, an answer to “what did rangatira cede in 1840?”
Present-day authority
Sovereign in right of New Zealand, responsible executive government, Parliament and courts operate under a domestically independent constitutional order.
Foundational question
The Act continues the institutional chain. It does not reenact or renegotiate the original Treaty settlement of authority.
Evidence update: the separate United Kingdom repeal
Section 26 of the Constitution Act 1986 addresses the effect of Imperial constitutional enactments as part of New Zealand law. It is not the same thing as a repeal enacted by the United Kingdom Parliament. The UK Parliament separately repealed the whole New Zealand Constitution Act 1852 through the Statute Law (Repeals) Act 1989, section 1 and Schedule 1, Part VI. That schedule expressly includes the 1852 Act (15 & 16 Vict. c.72), so section 71 is not a surviving operative UK statutory power.
These two legal events do not erase the historical existence of section 71, nor do they themselves determine the independent constitutional questions concerning He Wakaputanga, Te Tiriti, customary rights or historical Crown undertakings. The complete analysis also explains the difference between requesting a royal audience and asking the Sovereign to intervene in government.
