Through its three branches, the New Zealand Cadet Forces provide young adults with a four-year training curriculum, while a number of local, area, and national camps and courses provide further experience and qualifications. It is jointly funded by the Ministry of Defence, the Royal New Zealand Returned Services' Association, local communities, and the Associated charities belonging to each branch (CCANZ,SCANZ,ATCANZ). Overall it is directed by Air Marshal Kevin Short, Chief of Defence Force. Cadets are not under any obligation to join the New Zealand Defence Force, however many choose to do so upon turning 18 years old.

The New Zealand Cadet Forces is commanded by the Commandant New Zealand Cadet Forces (COMDT NZCF). Assisting the Commandant is the Executive Officer NZCF (XO NZCF), the Assistant Commandant (ASST COMDT NZDF), and the Cadet Warrant Officer Cadet Forces (WONZCF).

Training is provided by Cadet Force Officers, Cadet Non-Commissioned Officers, and adult volunteers through Cadet Units nationwide.

The New Zealand Cadet Forces also play a large role in supporting community projects through volunteer labour.
