The United Nations Handbook App is produced by the New Zealand Government as a ready reference guide. It provides current information about all the UN family organisations, including their purpose, evolution, structure and membership where applicable. It is not intended to be a historical record.

The Handbook has at its heart information about the six principal UN organs established by the UN Charter: the General Assembly, Security Council, Economic and Social Council, Trusteeship Council, International Court of Justice and the Secretariat.

It also contains information about subsidiary organs established in accordance with the Charter, related UN organs and programmes, specialised agencies and autonomous bodies related to the UN, and various ad hoc organs and programmes.

Non-governmental organisations with UN connections are not included; neither, generally, are other inter-governmental (but non-UN) organisations or political groupings.
