The New Zealand Mounted Rifles Brigade was composed of three Mounted Rifles Regiments. The Auckland Regiment, the Wellington Regiment, and the Canterbury Regiment. The Otago Mounted Rifles were not with the Brigade during the Sinai and Palestine campaigns. Each regiment was composed of three squadrons; and each of these squadrons was recruited from a regiment of Mounted Rifles in New Zealand; and the squadron bore the name of that regiment in New Zealand. So the Auckland Regiment consisted of the 3rd, 4th and 11th Squadrons coming from their parent regiments, 3rd (Auckland) Mounted Rifles, 4th (Waikato) Mounted Rifles, 11th (North Auckland) Mounted Rifles. The Wellington Regiment was composed of the 2nd, 6th and 9th Squadrons coming from Queen Alexandra's 2nd (Wellington West Coast) Mounted Rifles, 6th (Manawatu) Mounted Rifles, and the 9th (Wellington East Coast) Mounted Rifles. And the Canterbury Regiment consisted of the 1st, the 8th and the 10th Squadrons, from their parent regiments the 1st Mounted Rifles (Canterbury Yeomanry Cavalry), the 8th (South Canterbury) Mounted Rifles, and the 10th (Nelson) Mounted Rifles. From this it is seen that each of the three military districts, Auckland, Wellington and Canterbury, found one regiment.

            In addition to the three regiments the complete Brigade consisted of the Machine Gun Squadron, the Signal Troop, the Field Troop, the Mobile Veterinary Section, and the Mounted Field Ambulance. A battery of R.H.A. also always fought with the Brigade.
            The Machine Gun Squadron was formed early in the Sinai campaign from the machine gun sections of each regiment and was therefore recruited from all three regiments. Later as a complete unit the Machine Gun Squadron was reinforced from suitable men from any district in New Zealand.
            The Signal Troop were specialists principally from the Post and Telegraph Department and the Railways.
            The Field Troop was a unit formed in Sinai. They were the handy men of the Brigade; and among them were civil engineers, mechanical engineers, engine drivers, carpenters, plumbers, draughtsmen, surveyors and mechanics of all kinds. And the Troop was recruited from selected men chosen on account of their special qualification.
            The Mobile Veterinary Section was officered chiefly by veterinary officers belonging to the Agricultural Department and recruited from men selected in New Zealand. And, lastly the Mounted Field Ambulance was kept up to strength by men selected in New Zealand and sent with the other reinforcements.

            As to the R.H.A. Battery, for nearly the whole of the campaign the Somerset Territorial Battery, R.H.A., was attached to the New Zealand Brigade, and the men came almost to consider themselves New Zealanders, but the battery was, of course, recruited from England.
            Attached to the Brigade, though not actually working with it, were the Rarotongans formed into a company about 250 strong.
            In addition to the Brigade and its attached units, two Camel Companies were formed from Mounted Rifles reinforcements. These companies formed a part of the I.C.C. Brigade (Imperial Camel Corps) and fought in the Sinai and Palestine campaigns. On June 10th, 1918, they were disbanded and formed into the 2nd M.G. Squadron, and as such were attached to the 5th Australian L.H. Brigade.
