assist in conducting training. This is normally because they know a cadet/officer in that unit, or if they have a particular interest in cadet forces. They are addressed as "Instructor" or by cadets choice, "Sir" or "Ma'am". Fees NZCF Officers do not typically pay any membership fees for belonging to a Unit or Training Ship, this is typically to balance the time and effort put in by NZCF Officers. While Officers aren't encouraged to, a large amount contribute anyway, by way of purchasing stationary and equipment for their unit. Courses Each year the New Zealand Cadet Forces holds numerous courses designed to train and maintain the skills of all its personnel. Twice per year (Mid and late year) Headquarters, NZCF promulgates the NZCF Annual Training Programme or 'ATP', which represents the "Authorised Activities" that are undertaken by the NZCF. "Authorised Activities" are those which are at least partially funded by the New Zealand Defence Force and the support organisations for each branch (SCANZ/CCANZ/ATCANZ). Any other activity undertaken such as unit camps are "Recognised Activities" and receive no formal funding from the NZDF and are not included on the ATP. Each course is staffed by a mix of Defence and Cadet Force personnel, with the bulk of staff being Cadet Forces Officers with Defence staff often performing logistics and support roles such as administrators. However, more enthusiastic personnel are often actively involved in the courses and provide an opportunity for cadets to ask questions regarding recruitment into the New Zealand Defence Force. Tri-Corps promotional courses are held in each area up to three times per year (each school holidays excluding Christmas holidays) depending on requirements, with courses occasionally being removed if there aren't enough applicants. Conversely, if a course in one area is removed then students from that area may be transported to and from another area (whichever has space on a course) for the student to undertake the course. NZCF Courses Tri Corps Courses Tri Corps Courses are available to everybody in the New Zealand Cadet Forces regardless of which branch they're in. *Personnel are required to undergo further training before being eligible to act in a staff role. This will always be passing the course as a student first. Sea Cadet Corps Courses These courses and exercises are normally restricted to cadets in the Sea Cadet Corps. However, occasionally Officers from other branches will attend either as staff members
