McManemin was also a member of the organising committee for the 1950 Auckland Empire Games and the 1974 Christchurch Commonwealth Games.
He was made a commander of the order of the British Empire in the 1974 Queen's Birthday honours and received the Queen's Service Order in the 1990 New Year honours, while in 1986 he was appointed grand master of New Zealand's Freemasons.
McManemin was known for keeping his little black bag full of all sorts of medicinal odds and ends close at hand, and always assisted with medical support at athletic meetings and pushed for the inclusion of qualified medical support people to accompany our games teams.
His medical knowledge proved invaluable in Rome, keeping the 1960 team free of dysentery, after the New Zealanders battled illness in Cardiff in 1958.
On another occasion, driving home after a meeting one night in 1972, he came across a motor accident and was quickly on the spot doing all he could for the victims while they awaited the arrival of an ambulance.
