New Zealand military ranks are largely based on those of the United Kingdom. The three forces (army, navy, and air force) have their own rank structure, with a rank equivalency that allows seamless interoperability between the services. All three services form part of the New Zealand Defence Force.
Note: naval enlisted personnel are referred to by both rank and trade. Thus a sailor employed as a chef would hold the rank of ordinary chef (OCH) (with a few exceptions); a warrant officer with a trade of weapon technician would hold the rank of warrant officer weapon technician (WOWT).
A non-commissioned officer is defined as:
Officers of the New Zealand Defence Force are commissioned by the governor general on behalf of the New Zealand Sovereign, Queen Elizabeth II. See also Officer (armed forces). Salutes rendered to officers by junior officers and enlisted personnel are indirect salutes to the sovereign, based on the officer holding the monarch's authority.
Appointments to the most senior ranks (those above the rank held by the chief of the defence force, usually lieutenant general or equivalent) are ceremonial, for the head of state and members of the royal family.
