Section 49 of the Defence Act 1990 allows Service personnel to make a complaint if they consider they have been wronged in any manner. The channel for complaints in the NZDF is the command chain. If Service personnel are unable to obtain redress through their respective Service, complaints can be forwarded to the Chief of Defence Force, who is the final authority for redress. Complaints made to the CDF are referred to the Judge Advocate General (JAG), who investigates complaints and makes recommendations to the CDF. The CDF makes the final decision on a complaint, and that decision is conveyed in writing through the command chain to the complainant.
