What exact instrument displaced the United Tribes flag after 1840?
Official histories consistently say the Union Jack replaced the United Tribes flag in 1840. The legal question is narrower: what instrument actually did that work? The record located so far shows a sovereignty assertion, executive removal of the earlier flag, suppression of competing colonial authority and subsequent official practice. It does not yet reveal a single instrument expressly revoking the 1834 flag by name.

The official histories agree on the outcome
Manatū Taonga states that after the Treaty of Waitangi the Union Jack replaced the United Tribes flag as New Zealand's official flag. Te Ara similarly describes the Union Jack as replacing the United Tribes flag as the recognised flag of New Zealand. National Library catalogue material records the United Tribes ensign as remaining the national ensign until 1840, when the Union Jack superseded it.
The 21 May proclamations asserted sovereignty, not flag revocation
Hobson's proclamations of 21 May 1840 declared that sovereignty over the North Island, and then the islands of New Zealand generally, vested in Queen Victoria. Archives New Zealand describes this as Britain's formal assertion of sovereignty. The text of the proclamations concerns sovereignty. It does not, on the material located so far, expressly state that the 1834 United Tribes flag is revoked, abolished or replaced.
What the proclamations did
Asserted that full sovereignty vested in the British Crown and purported to define the territorial reach of that sovereignty.
What they have not yet been shown to do
Expressly repeal, revoke or cancel the 1834 flag recognition by name.
At Port Nicholson the transition was enforced physically
The documentary trail then becomes operational. Te Papa records that when the New Zealand Company continued to fly its version of the earlier New Zealand flag, Hobson treated that as a challenge to Crown authority. An armed party was sent to lower it on 30 June 1840; the Union Jack was raised the next day and British sovereignty proclaimed locally.
Te Ara likewise records that Hobson regarded continued use of the United Tribes-derived flag as high treason and sent troops to lower it and hoist the Union Jack.
The Port Nicholson proclamation was about authority
The proclamation dealing with the Port Nicholson council ordered those involved in the "illegal" association to withdraw and required people within the claimed government to submit to authorities appointed by the Crown. The Waitangi Tribunal's later account describes it as a response to what Hobson characterised as an attempted usurpation of powers vested in him.
Again, the legal target was rival governmental authority. The flag mattered because it symbolised that authority. The proclamation did not need to operate as a modern flag statute in order for the Crown administration to treat the Union Jack as the governmental flag.
This is a different kind of legal transition from 1902
The later adoption of the present New Zealand flag followed a clearer statutory route through the New Zealand Ensign legislation. The 1840 transition appears different. On the evidence located so far, it was bound up with the Crown's assertion and enforcement of sovereignty rather than a discrete enactment saying that one national flag was hereby repealed and another substituted.
| Stage | Instrument / act | Effect proved by current evidence |
|---|---|---|
| 1834 | Rangatira selection, Busby declaration, royal approval and Admiralty recognition | United Tribes flag recognised as New Zealand's flag for maritime and national purposes. |
| 21 May 1840 | Hobson sovereignty proclamations | Crown asserts full sovereignty; no express flag revocation yet located. |
| June–July 1840 | Port Nicholson intervention | United Tribes-derived flag physically lowered; Union Jack raised; Crown authority enforced. |
| 1840 onward | Colonial governmental practice | Union Jack treated as official/recognised flag on shore. |
| 1901–1902 | New Zealand Ensign legislation | Present flag established through statute. |
So did the flag disappear legally or politically?
The current evidence supports a careful answer: the United Tribes flag was displaced in Crown governmental practice as a consequence of Britain's asserted sovereignty and the enforcement of colonial authority. We have not yet located a separate 1840 legal instrument expressly extinguishing the earlier flag's status by name.
That distinction matters. A change in which flag government institutions use is evidence of a change in governmental practice and asserted authority. It is not, by itself, proof that every legal or constitutional meaning attached to the earlier flag was expressly extinguished.
Why this matters for 28 October 2026
The 2026 request does not require the argument that the United Tribes flag remained the operative national flag after 1840. Its stronger basis is narrower and already documented: the flag has an official 1834 pedigree, is still described by Government institutions as New Zealand's first recognised or national flag, and NZTA itself contemplated flying it on the Auckland Harbour Bridge in 2009.
If the Government says the flag lost all official significance in 1840, the proper evidential question is now precise: identify the instrument relied upon for that proposition and distinguish a change in Crown governmental practice from an express extinguishment of the earlier flag's historical status.
