He was selected as a member of Kristiania's school board in 1913. In 1921 he advanced to chairman, a post he held until 1923. In the 1918 Norwegian parliamentary election he stood on the Conservative Party ballot in Uranienborg and was elected to the Parliament of Norway in that single-member constituency. He was nominated as the party's candidate in Uranienborg as a compromise candidate between the agrarian-conservative wing of Jens Bratlie and the liberal wing of Fredrik Stang, Nils Yngvar Ustvedt and Edvard Hagerup Bull (Bratlie, Stang and Ustvedt were former MPs from Uranienborg). Hambro received 14,501 votes, and thus won a landslide victory. The closest runner-up was G. E. Stubberød of Labour, who tallied only 1,504 votes.
