The Ministry of Defence () is the public service department of New Zealand responsible for advising the government on strategic defence policy, acquiring military equipment to meet defence capability and conducting audits and assessments of the New Zealand Defence Force. History The Defence Act, passed on 17 November 1964, established a new Ministry of Defence. Under the Act the three Service departments were combined into the new Ministry. The central core of the new Ministry of Defence was the central Defence Office. A Defence Council was established which consisted of: Minister of Defence Chief of Defence Staff Secretary of Defence Chiefs of Staff from the three Services Co-opted members if required (especially the Secretaries of External Affairs and Treasury) The Defence Council was responsible for: Administering and commanding the Services Advising the Minister on defence policy Integrating common functions where desirable and practical The boards for each service continued to exist, but they acted under delegated power from the Defence Council. The Chiefs of Staff Committee was retained, but as a committee of the Defence Council. (The Defence Council was later abolished under the Defence Act 1990). In 1969-71 moves were implemented to provide a fully centralised administration in control of all non-operational functions previously within the responsibility of the three services. These changes were embodied in a further Defence Act that came into effect on 1 April 1972. The Service Boards were abolished and their functions divided between the Chiefs of Staff and a central Defence Headquarters that replaced the Defence Office. The disadvantage of the continued existence of the Service Boards had been one that the one Service could still express its views to the Minister independently of the other Services. Policy formation and planning, logistics and supply, personnel, administration, finance, civil management, and management services were transferred to the central Defence Headquarters. Each Chief of Staff and their separate Headquarters were now only concerned with operational matters. In 1989 Defence was separated into two separate bodies – the Ministry of Defence headed by the Secretary of Defence, the senior civilian officer and the New Zealand Defence Force headed by the Chief of Defence Force (CDF), the senior military officer. Both are equally answerable to the Minister of Defence for their individual elements. Under the CDF are the three service chiefs who, as the senior officers of their individual services, act as advisors to CDF and provide forces
