Nukunonu
atoll in Tokelau

Nukunonu, formerly known as Duke of Clarence Island, is the largest atoll within Tokelau, a dependency of New Zealand in the south Pacific Ocean. It comprises 30 islets surrounding a central lagoon, with about 5.5 km2 (2.1 sq mi) of land area and a lagoon surface area of 109 km2 (42 sq mi). Motuhaga is the only islet that has inhabitants. It has an estimated population of 531.
History
The first European vessel known to have come upon Nukunonu was the Royal Navy ship HMS Pandora, in 1791, whose captain, Edward Edwards, named Duke of Clarence Island in honour of Prince William, Duke of Clarence and St Andrews (1765-1837), the third son of King George III and later king himself, as William IV. At the time, the Pandora was searching for mutineers from HMS Bounty. During the early 19th century, Nukunonu's inhabitants were converted to Roman Catholicism by Samoan missionaries.
In 1859, the U.S. Guano Company claimed Duke of Clarence along with a number of other Tokelauan atolls under the U.S. Guano Islands Act. The U.S. State Department bonded the claim in 1860. However, many of these islands were not worked by the company and in 1889 they were claimed by Great Britain as part of the Union Islands. In 1916, the Union Islands were annexed to the Gilbert and Ellice Islands colony and then, in 1925, reassigned to the Dominion of New Zealand under the administration of Territory of Western Samoa.

Why this record matters
The phrase “atoll in Tokelau” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 11, 2026. The linked authority identifier is Q656709. VIAF identifies the subject as 315127997. Authority coordinates are -9.168, -171.810. None of the 2 selected statements returned an explicit reference. The first chronological checks are 1791, 1765, 1837 and 1859.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
