The New Zealand Order of Merit is an order of merit in the New Zealand royal honours system. It was established by royal warrant on 30 May 1996 by Elizabeth II, Queen of New Zealand, "for those persons who in any field of endeavour, have rendered meritorious service to the Crown and nation or who have become distinguished by their eminence, talents, contributions or other merits", to recognise outstanding service to the Crown and people of New Zealand in a civil or military capacity.

The New Zealand royal honours system, a system of orders, decorations and medals, recognises achievements of, or service by, New Zealanders or others in connection with New Zealand. Until 1975, New Zealand used the British honours system. Since then the country has introduced a number of uniquely New Zealand honours, and as of 2021, only the dynastic British honours continue in active use in New Zealand, with the exception of the Order of the Companions of Honour.
