There were about 305,000 courts-martial in the British (and Dominions) Army in the Great War. The only ones for which records of the proceedings have survived are the 350 or so that resulted in an execution and these are in the National Archives at Kew, SW London, in class WO71.
There are some registers of courts-martial in classes WO84 and WO86.
Is there an organisation in NZ similar to the AWM in Canberra? If so, they may have copies of the unit War Diaries, including the A&Q Diary of the NZ Division, and one of these may have information about the courts-martial.
