South Pacific Nuclear Free Zone Treaty 

6 August 1985 

Entry into Force 11 December 1986 

PREAMBLE 

The Parties to this Treaty 

United in their commitment to a world at peace; 

Gravely concerned that the continuing nuclear arms race presents 
the risk of nuclear war which would have devastating 
consequences for all people; 

Convinced that all countries have an obligation to make every 
effort to achieve the goal of eliminating nuclear weapons, the 
terror which they hold for humankind and the threat which they 
pose to life on earth; 

Believing that regional arms control measures can contribute to 
global efforts to reverse the nuclear arms race and promote the 
national security of each country in the region and the common 
security of all; 

Determined to ensure, so far as lies within their power, that 
the bounty and beauty of the land and sea in their region shall 
remain the heritage of their peoples and their descendants in 
perpetuity to be enjoyed by all in peace; 

Reaffirming the importance of the Treaty on the 
Non-Proliferation of Nuclear Weapons (NPT) in preventing the 
proliferation of nuclear weapons and in contributing to world 
security; 

Noting, in particular, that Article VII of the NPT recognises 
the right of any group of States to conclude regional treaties 
in order to assure the total absence of nuclear weapons in their 
respective territories; 

Noting that the prohibitions of emplantation and emplacement of 
nuclear weapons on the seabed and the ocean floor and in the 
subsoil thereof contained in the Treaty on the Prohibition of 
the Emplacement of Nuclear Weapons and Other weapons of Mass 
Destruction on the Seabed and the Ocean Floor and in the Subsoil 
Thereof apply in the South Pacific; 

Noting also that the prohibition of testing of nuclear weapons 
in the atmosphere or under water, including territorial waters 
or high seas, contained in the Treaty Banning Nuclear Weapon 
Tests in the Atmosphere, in Outer Space and Under water applies 
in the South Pacific; 

Determined to keep the region free of environmental pollution by 
radioactive wastes and other radioactive matter; 

Guided by the decision of the Fifteenth South Pacific Forum at 
Tuvalu that a nuclear free zone should be established in the 
region at the earliest possible opportunity in accordance with 
the principles set out in the communique of that meeting; 

Have Agreed as follows: 

Article 1

Annex 2 

IAEA SAFEGUARDS 

1. The safeguards referred to in Article 8 shall in respect of 
each Party be applied by the IAEA as set forth in an agreement 
negotiated and concluded with the IAEA on all source or special 
fissionable material in all peaceful nuclear activities within 
the territory of the Party, under its jurisdiction or carried

2. The agreement referred to in paragraph 1 shall be, or shall 
be equivalent in its scope and effect to, an agreement required 
in connection with the NPT on the basis of the material 
reproduced in document INFCIRC/153 (Corrected) of the IAEA. Each 
Party shall take all appropriate steps to ensure that such an 
agreement is in force for it not later than eighteen months 
after the date of entry into force for that Party of this 
Treaty. 

3. For the purposes of this Treaty, the safe-guards referred to 
in paragraph 1 shall have as their purpose the verification of 
the non-diversion of nuclear material from peaceful nuclear 
activities to nuclear explosive devices.

transmit to that Party and to the Director for the information 
of all Parties a copy of the overall conclusions of the most 
recent report by the IAEA on its inspection activities in the

Annex 4 

COMPLAINTS PROCEDURE 

1. A Party which considers that there are grounds for a 
complaint that another Party is in breach of its obligations 
under this Treaty will, before bringing such a complaint to the 
Director, bring the subject matter of the attention of the Party 
complained of and shall allow the latter reasonable opportunity 
to provide it with an explanation and to resolve the matter. 

2. If the matter is not so resolved, the complainant Party may 
bring the complaint to the Director with a request that the 
Consultative Committee be convened to consider it. Complaints 
shall be supported by an account of evidence of breach of 
obligations known to the complainant Party. Upon receipt of a 
complaint the Director shall convene the Consultative Committee 
as quickly as possible to consider it. 

3. The Consultative Committee, taking account of efforts made 
under paragraph 1, shall afford the Party complained of a 
reasonable opportunity to provide it with an explanation of the 
matter. 

4. If, after considering any explanation given to it by the 
representatives of the Party complained of, the Consultative 
Committee decides that there is sufficient substance in the 
complaint to warrant a special inspection in the territory of 
that Party or elsewhere, the Consultative Committee shall direct 
that such special inspection be made as quickly as possible by a 
special inspection team of three suitably qualified special 
inspectors appointed by the Consultative Committee in 
consultation with the complained of and complainant Parties, 
provided that no national of either Party shall serve on the 
special inspection team. If so requested by the Party complained 
of, this special inspection team shall be accompanied by 
representatives of that Party. Neither the right of consultation 
on the appointment of special inspectors, nor the right to 
accompany special inspectors, shall delay the work of the 
special inspection team. 

5. In making a special inspection, special inspectors shall be 
subject and shall comply with such directives concerning tasks, 
objectives, confidentiality and procedures as may be decided 
upon by it. Directives shall take account of the legitimate 
interests of the Party complained of in complying with its other 
international obligations and commitments and shall not 
duplicate safeguards procedures to be undertaken by the IAEA 
pursuant to agreements referred to in Annex 2(1). The special 
inspectors shall discharge their duties with due respect for the 
laws of the Party complained of. 

6. Each Party shall give to special inspectors full and free 
access to all information and places within its territory which 
may be relevant to enable the special inspectors to implement 
the directives given to them by the Consultative Committee. 

7. The Party complained of shall take all appropriate steps to 
facilitate the special inspection, and shall grant to special 
inspectors privileges and immunities necessary for the 
performance of their functions, including inviolability for all 
papers and documents and immunity from arrest, detention and 
legal process for acts done and words spoken and written, for 
the purpose of the special inspection. 

8. The special inspectors shall report in writing as quickly as 
possible to the Consultative Committee, outlining their 
activities, setting out relevant facts and information as 
ascertained by them, with supporting evidence and documentation 
as appropriate, and stating their conclusions. The Consultative 
Committee shall report fully to all Members of the South Pacific 
Forum, giving its decision as to whether the Party complained of 
is in breach of its obligations under this Treaty. 

9. If the Consultative Committee has decided that the Party 
complained of is in breach of its obligations under this Treaty, 
or that the above with, or at any, time at the request of either 
the complainant or complained of Party, the Parties shall meet 
promptly at a meeting of the South Pacific Forum.
