The United Nations Handbook is the only comprehensive printed guide to the United Nations system and how it works. The handbook summarises all United Nations organisations and provides essential information about their aims, structures, and membership. It is a useful reference tool for delegates, diplomats, foreign ministry officials, academics, media, and members of the public. The handbook has been published annually since 1961 by the New Zealand Ministry of Foreign Affairs and Trade. It symbolises New Zealand’s longstanding and practical commitment to the United Nations.
