He served as Senior Government Whip in Norman Kirk's 1972–1975 Government, and Freer said he was an outstanding whip. When Barclay realised that Arthur Faulkner had the votes to win the first ballot for deputy to Bill Rowling in 1974, he got Warren Freer (who was not interested in the position, but who agreed that Faulkner was not leadership material) nominated to split the first vote. They preferred either Colin Moyle (Barclay) or Bob Tizard (Freer), and Tizard won on the fourth ballot. He was the first Deputy Chairman of Committees (1975). He was defeated in the swing againdst Labour in the 1975 election .
Subsequently, he served as a New Plymouth city councillor from 1977 to 1989, including three years as deputy mayor.
