Member of Parliament
Ridley was the MP for Taupo for six years from to 1975, and from  to 1981.

He was once asked why there were so few engineers in Parliament, to which he replied: "Because engineers are realists and politicians are idealists." In 1975 his wife Avis unsuccessfully sought the Labour Party candidacy for the electorate alongside 26 other aspirants following the retirement of Hugh Watt, but she lost to Frank Rogers.

Independent
In October 1983 Ridley contested the Labour nomination for the new Tongariro electorate but was unsuccessful, losing to Noel Scott. Ridley disputed the selection process afterwards, claiming that the procedure had been manipulated by the party hierarchy who were determined to select Scott and estimating that he won 250 of the 350 floor votes from the members opposed to less than 20 for Scott. The party president, Jim Anderton, refuted Ridley's claims stating that Labour's selection processes were democratically sound and the decision was final. In the Ridley stood for the Tongariro electorate as an Independent but was not successful. A large proportion of the Tongariro electorate had been part of Taupo. The city of Taupo itself however had become part of Waikaremoana.
