Adult members can serve in two capacities: commissioned officers or civilian instructors. Officers are commissioned into the New Zealand Cadet Forces, with the post-nominal letters NZCF, at the rank of second lieutenant, and can be promoted to lieutenant, captain or major after completing the necessary training and service. To reach captain the officer must have served as the commanding officer of a cadet unit, while officers must be an area support officer to be promoted to major. At the end of 2014, the NZCF introduced a new position of national support officer (NSO). If he or she is an NZCC officer, as opposed to an ATC or SCC officer, they will hold the rank of lieutenant colonel.
