How did the British Crown become the Crown in right of New Zealand?

There was no sale or assignment of one Crown to another. Constitutional development produced a legally distinct New Zealand capacity of the same monarchy.

Divisible Crown

Modern constitutional language can make it sound as though a British Crown was somehow transferred to a separate New Zealand Crown. That is not the legal mechanism.

Across the twentieth century the Crown became constitutionally divisible between the different realms. The same natural person could act as sovereign of the United Kingdom in one legal capacity and sovereign of New Zealand in another.

The Royal Titles Act 1974 made the New Zealand capacity explicit in the sovereign's style: “Queen of New Zealand”. The 1983 Letters Patent then constituted the office of Governor-General of New Zealand under New Zealand's own constitutional arrangements.

This helps explain how the same institutional genealogy can move from an imperial Crown to a domesticated New Zealand Crown without a deed assigning the country from one monarch to another.

But again, this is a constitutional evolution inside the Crown order. The divisibility of the Crown explains how modern state authority is legally localised. It does not itself establish what rangatira authorised in 1840.

The distinction also prevents a common analytical error: treating present-day ministers as agents of the United Kingdom Government. They are not. They advise the Sovereign in right of New Zealand under New Zealand constitutional law.

The Crown became New Zealand's Crown by constitutional differentiation, not by a secret conveyance of territory.
