Career
Early Born in Caven, Ireland in 1875, McManus immigrated to Australia and was the organizer of the Australian Workers" Union from 1900 to 1905. He then shifted to New Zealand in 1906, joining the New Zealand Socialist Party and becoming the Secretary of the Dunedin General Labourers Union. By trade he was a tunneller, working for the Public Works Department in Kahnika.
During the factional bickering amongst the early Labour movement in New Zealand, McManus sided with Paul and David McLaren.
McManus was the Labour Party candidate for Dunedin South in 1911, narrowly losing to Liberal Party incumbent Thomas Kay Sidey in a two-horse race. Had an Independent Liberal or Reform Party candidate also contested and forced a second ballot, McManus may well have been elected to Parliament.
Despite, like Paul, thinking the Waihi miners" strike was futile, McManus was one of the United Labour Party members who favoured the establishment of the Social Democratic Party (Social Democratic Party) in 1913. The Social Democratic Party was strongly opposed by Paul, though the pair remained on speaking terms with one another.
In 1915, McManus enlisted to serve in World War I. He saw action in France as a sapper with the New Zealand Engineers Tunnelling Company.
McManus was the Labour Party"s candidate for Dunedin West 1922 and for Dunedin South again in 1925. He was unsuccessful on both occasions. However, he was later elected as a Dunedin City Councillor in 1923 before suffering a stroke in 1926.
He then became a farmer from 1926 to 1938.
MacManus died 1950.
