His social conscience was much appreciated during the Depression era, as was his insistence that his salary should be cut as were the salaries of public servants at the time. Bledisloe also contributed to improved Pākehā–Māori relations, purchasing the site where the Treaty of Waitangi was signed and presenting it to the nation as a memorial. In 1934, the site was dedicated as a national reserve. The dedication ceremony attracted thousands of people, both Māori and Pākehā. Bledisloe continued to take an interest in the site even after his term expired and he returned to England. He also contributed to the recognition of the Māori King Movement by developing a friendship with King Koroki and Te Puea Herangi, and his willingness to use the title "king" without reticence.
