Laney's political career began in 1951 when he was elected as a member of the Oamaru Borough Council in a by-election.[4] He was then Mayor of Oamaru for 18 years from 1956 to 1974. From 1945 until 1956 he was an executive member of the Oamaru branch of the National Party but he resigned to join the Labour Party in order to contest the mayoralty. His resignation did not endear him to the local National Party faithful.[3] This was compounded by the fact that the incumbent mayor he defeated, Michael Francis Edward Cooney, was a prominent member of the local National Party.[5]
Laney contested the Oamaru electorate in the 1972 election, and defeated the incumbent, National's Allan Dick by a 390 votes majority.[6] At the next election in 1975, he was in turn defeated by National's Jonathan Elworthy.[7] Laney was described as a man of integrity not prepared to compromise his principles and opposed the influence liquor industry lobbyists had over politicians during his time as an MP.[8]
After losing his seat in Parliament Laney stood for the Oamaru mayoralty once again at the 1977 local elections, but was beaten by the deputy mayor Reginald James Denny by 1,415 votes.[9] A year later at the 1978 election, he stood for Labour in Waitaki (Oamaru having been abolished) where he again finished runner-up to Elworthy.
