James Mills (ship owner)  Sir James Mills (30 July 1847 – 23 January 1936) was a New Zealand businessman and politician. He founded the Union Steam Ship Company in Dunedin in 1875. Mills was born in Wellington and raised in Dunedin. He worked for Johnny Jones, starting as a shop assistant and working his way up to managing Jones' Harbour Steam Company. After Jones' death in 1869 he became the leading trustee of his estate. Between 1869 and 1871 he built up a shareholding in the Harbour Steam Company until he was able to control the company. He floated the Union Steam Ship Company of New Zealand in 1875 with backing from Scottish shipbuilder Peter Denny in return for orders for his Dumbarton shipyard. The Union Company (as it was known) became a major shipping line, with a near-monopoly on trans-Tasman shipping, and was referred to as the "Southern Octopus". By 1914 it had 75 ships. It was the biggest shipping line in the southern hemisphere and New Zealand's largest private-sector employer. Mills sold the Union Company to the Peninsular and Oriental Steam Navigation Company (P&O) in 1917. He represented Waikouaiti on the Otago Provincial Council in 1870, and again from 1873 to 1876. Later, he represented the electorate in Parliament from a by-election in to 1893, when he retired. He was knighted in 1907, and appointed Knight Commander of the Order of St Michael and St George in 1909. It was said in a tribute to Mills that these distinctions made him the first native-born, non-indigenous New Zealander to be so honoured. He died in London in 1936, having been a UK resident since 1907. Mount Mills in Antarctica is named after Mills.
