Treaty did not create decent grounds for such an international organization. He chaired the Standing Committee on Foreign and Constitutional Affairs from 1925 to 1945, and was then a member from 1945 to 1957. From 1945 to 1957 he was also a member of the Enlarged Committee on Foreign and Constitutional Affairs. In the Election Committee of the Parliament, he was the chairman from 1928 to 1945 and deputy chairman from 1945 to 1957. Hambro served as acting party chairman in 1926, and party chairman from 1928 to 1934 and 1945 to 1954. He was also a central board member from 1934 to 1964. He was never a member of any government, despite that his party formed several cabinet during his parliamentary tenure. He instead chose to work as chairman of his party as well as its parliamentary group; the two posts had actually become open to him when Ivar Lykke chose to form his cabinet in 1926.

However, when forces in and outside of the then-Agrarian government annexed "Erik the Red's Land" in 1931, Hambro was strictly against it. The Agrarian Party revenged itself on Hambro by voting him down as President of the Parliament in 1934, but Hambro won support from the adversaries in the Labour Party to regain the post. He nurtured a personal friendship with figures such as the Labour Party's foremost politician, Johan Nygaardsvold. Despite his family's Jewish roots, Hambro was a Christian. He more or less adhered to the views of the Oxford Group, without being an actual member of this group. He famously invited the Oxford Group's founder, Frank Buchman, and a large party of Oxford Group members to Norway in 1934 where they led a massive campaign for "a Christian revolution" leading to a kind of "national awakening" credited with strengthening Norwegian spirit of resistance during World War II.
