Someone joining the 3rd New Zealand Rifle Brigade (the 1st and 2nd Brigades consisted confusingly of the Otago, Auckland, Wellington and one other Regt) would have done so from another regiment (e.g Otagos) due to a specialist skill - usually accuracy with a rifle (i.e a good shot), or bombing etc..
During their time at the camp at Brocton the 3rd NZRB constructed a concrete model of the victory at Messines Ridge that was some 40 yards by forty yards. Some of this still exhists. The mascot Freda moved with them from Sling camp in September 1917, dting in Decmber 1918. She was a Great DAne (harlequin) - forget any inaccurate statements she was a Dalmation!
All the best
