Treaty of Rarotonga
treaty against nuclear weapons in the South Pacific
The Treaty of Rarotonga is the common name for the South Pacific Nuclear Free Zone Treaty, which formalises a nuclear-weapon-free zone in the South Pacific. The treaty bans the use, testing, and possession of nuclear weapons within the borders of the zone.
It was signed by the South Pacific nations of Australia, the Cook Islands, Fiji, Kiribati, Nauru, New Zealand, Niue, Papua New Guinea, Samoa, Solomon Islands, Tonga, Tuvalu, and Vanuatu on the island of Rarotonga (where the capital of the Cook Islands is located) on 6 August 1985, came into force on 11 December 1986 with the 8th ratification, and has since been ratified by all of those states.
The Marshall Islands, the Federated States of Micronesia, and Palau were outside the original geographic scope of the treaty but are eligible to become parties, in which case that scope would be expanded. The Marshall Islands signed the treaty on 3 March 2025, but has yet to ratify it as of June 2026.
Protocols binding other states
There are three protocols to the treaty, which have been signed by the five declared nuclear states, with the exception of Protocol 1 for China and Russia who have no territory in the Zone.
no manufacture, stationing or testing in their territories within the Zone
no use against the Parties to the Treaty, or against territories where Protocol 1 is in force
no testing within the Zone
In 1996 France and the United Kingdom signed and ratified the three protocols. The United States signed them the same year but has not ratified them. China signed and ratified protocols 2 and 3 in 1987. Russia has also ratified protocols 2 and 3 with reservations.

Why this record matters
The subject matters to the history & society register because the source frames it as treaty against nuclear weapons in the South Pacific. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The record creator and administrative purpose are central evidence, because official documentation reflects both action and institutional priorities. The source revision retrieved here is dated Jul 7, 2026. The linked authority identifier is Q1760687. VIAF identifies the subject as 179526127. The Library of Congress control number is n96007626. Authority coordinates are -21.229, -159.777. 2 of 4 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1985, 1986, 2025 and 2026.
Institutional narratives can privilege the records that survived while minimizing voices that were never formally collected. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
