In 1962, he won the 1962 Waitaki by-election,[2] after the sudden death of the Hon. Thomas Hayman, who had been an MP from 1949.[3] He was one of six candidates for the National nomination in this largely rural and safe National seat. He represented the Waitaki electorate to 1969, and then the Oamaru electorate from 1969 to 1972, when he was defeated.[2] He was one of four National Party incumbents from Otago and Southland who lost their normally blue electorate to the Labour challenger over the proposed raising of the lake levels of lakes Manapouri and Te Anau, which was opposed by the Save Manapouri campaign. Labour's election manifesto was for the lakes to remain at their natural levels.[4]
Dick died in Oamaru on 15 March 1992.[6] His wife, Betty Dick, wrote a book High Country Family (Reed, Wellington, 1964) about their life on Lilybank Station, and the changes when he became an MP. They had four sons and one daughter.[citation needed]
