Wellington, and Canterbury Mounted Rifles Regiment made, with the Field and Signal Troops and Mounted Field Ambulance, a complete mounted brigade. The Otago Mounted Rifles Regiment became divisional cavalry, and did not form part of the brigade. The four infantry battalions—Auckland, Wellington, Canterbury, and Otago—made a complete infantry brigade.

The characteristic slouch hat, with the brim down all round, was adopted by the whole force; but the Otago Mounted Rifles, the New Zealand Field Artillery, and the Wellington Infantry Battalion wore their hats peaked and with four dents. After the evacuation of the Gallipoli Peninsula the entire New Zealand Division wore peaked hats, but the New Zealand Mounted Rifles remained faithful to the old style. A further distinguishing mark was the different coloured puggaree for each branch of the service. The troopers of the Mounted Rifles wore khaki and green; the gunners, red and blue; the sappers, khaki and blue; the infantry, khaki and red; the Army Service Corps, khaki and white; and the men of the Field Ambulance, khaki and maroon.
