Latest developments
In 2021, Niue adopted The Prohibition of Nuclear Weapons Act, which is explicitly aimed at giving effect to the TPNW.2 Niue thus became one of the first States Parties to adopt national legislation specifically implementing the TPNW, in accordance with the Treaty’s Article 5.
At the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) Preparatory Committee meeting in April 2025, the States Parties to the South Pacific Nuclear Free Zone Treaty, including Niue, reaffirmed their commitment to a nuclear-weapon-free world. ‘As a region devastatingly affected by nuclear testing, the slow pace of nuclear disarmament is a significant concern,’ they said.3
At a high-level event on 26 September 2025 marking the International Day for the Total Elimination of Nuclear Weapons, the Pacific Islands Forum, of which Niue is a member State, noted the ‘significant contribution’ of the 1985 South Pacific Nuclear Free Zone Treaty to nuclear non-proliferation and disarmament and to ‘inspiring other nuclear-weapon-free zones around the world’.4
Recommendations
-
Niue should continue to encourage other states to adhere to the TPNW.
