Latest developments

When Niue acceded to the TPNW in August 2020, the Premier of Niue, Dalton Tagelagi, issued a national statement that said: 'Niue is honoured to accede to the Treaty on the 2017 Prohibition of Nuclear Weapons and draw us closer to witnessing this very significant Treaty enter into force. [...] [N]o state is immune to the threats and consequences of nuclear weapons. [...] We recall the vision and values of our Pacific Leaders for a region of 'peace, harmony, security, social inclusion and prosperity so that all Pacific people can lead free, healthy and productive lives. As a global citizen we renew our pledge to ensuring the achievement of this vision and endeavour to uphold Niue's commitment to the international community in the enforcement and implementation of this treaty including the enactment of national legislation in Niue. [...] We are hopeful that more States join us in this united commitment to enter this Treaty into force in the near future and eliminate nuclear weapons altogether.' See:


  • Niue should encourage other states to adhere to the TPNW.
  • Niue should ensure that all the TPNW obligations are implemented domestically, through legal, administrative, and other necessary measures.
  • Niue should conclude and bring into force an Additional Protocol (AP) with the IAEA.
