Joseph Gordon Coates (3 February 1878 – 27 May 1943) served as the 21st prime minister of New Zealand from 1925 to 1928. He was the third successive Reform prime minister since 1912. Born in rural Northland, Coates grew up on a cattle run and was bilingual in English and Te Reo Māori, the last New Zealand Prime Minister to be so. Coates took charge on the farm as a young age due to his father's mental illness, before becoming a Member of Parliament in 1911. He maintained a focus on farming issues and stood as an independent candidate. After distinguished service during World War I, he was appointed as Minister of Justice and Postmaster-General in the Reform government of William Massey (1919); he served as Minister of Public Works (1920–26) and Native Affairs (1921–28) and became prime minister in 1925 on Massey's death. Defeated in the elections of 1928, Coates returned to government in 1931 as the key figure in the coalition government of George Forbes. Serving as Minister of Public Works (1931–33) and of Finance (1933–35), he instituted rigorous policies to combat the economic depression of the 1930s. He became a member of Peter Fraser's War Administration from 1940, serving as Minister of Armed Forces and War Co-ordination until his death. Early life Born at Ruatuna in Hukatere in Kaipara Harbour, New Zealand, where his family ran a farm, Coates took on significant responsibility at a relatively early age because his father suffered from bipolar disorder. He received a basic education at a local school, and his well-educated mother also tutored him. He became an accomplished horseman, although an accident left him with a bad leg for the rest of his life. The large Māori population of the area meant that Coates grew up proficient in the Māori language. Gossip suggests that before his marriage, Coates had two children by a Māori woman. He allegedly became engaged to Eva Ingall, a teacher, but her father forbade marriage on the grounds that the illness of Coates' father might prove hereditary. Eventually, on 4 August 1914, he married Marguerite Grace Coles, better known as Marjorie Grace Coles, by whom he had five daughters. Early political career While farming in Auckland, Coates became active in farmers' organisations. He first became involved in politics through the Otamatea County Council, to which he won election in 1905. Later, from 1913 to 1916, he
