The Wakari Rifle Cadets were organished in April, 1902, as a training corps in connection with the Wakari Rifles, and for filling vacancies in that corps. The cadets number sixty-three, and the first commander was Captain J. D. Hawkes.

Lieutenant William Alexander Wilson , of the Wakari Rifle Cadets, joined the Wakari Rifle Corps in 1888, and remained a member until its disbandment three years later. He afterwards belonged to the Dunedin City Guards for two years, and when the Wakari Rifles were again formed he was a member of the corps for three years. Lieutenant Wilson joined the Wakari Rifle Cadets with his present rank in 1903.

Captain Sidney Nimmo Muir , Adjutant of the New Zealand Regiment of Artillery Volunteers, has always taken an interest in volunterring. In January, 1864, he joined the B Battery, originally known as the Dunedin Volunteer Artillery Regiment, and subsequently became, in succession, lieutenant and captain. He resigned his captaincy on the 16th of June, 1881, on being appointed adjutant. Captain Muir, while on a visit to the Old Country in 1886, attended a repository course of instruction in gunnery at Woolwich. In shooting competitions he has been eminently successful. He won the B Battery's champion cup the requisite four times, and now retains its possession, and he also won the first Provincial Cup shot for in Dunedin. In one of the shooting competitions for the New Zealand Champion Belt, Captain Muir gained fourth place. He was born in Adelaide, South Australia, where he attended school, but after removing with his parents to Melbourne, he studied at Fenner's Collegiate School and the Scotch College. In 1860 he arrived in Dunedin, and entered the office of the late Mr. George Cook, under whom he studied for the legal profession. In due course, Mr. Muir was admitted as a solicitor of the Supreme Court of New Zealand, and afterwards entered into partnership with Mr. Cook Muir subsequently retired from the firm, and has since lived in retirement in Dunedin. In social affairs he has taken an active interest. The Otago Rowing Club owes its inception to his efforts, and he was one of the founders of the Southern club. For some years he was honorary secretary of the Dunedin Choral Society, and also of the Orchestral Society. Mr. Muir has obligingly supplied the Cyclopedia Company's staff with many particulars in connection with volunteering in Otago.
