In January 1896 Reeves left New Zealand for London, where he was Agent General (1896–1905) and High Commissioner (1905–08). While he was in Britain Reeves became a friend of a number of left-wing intellectuals, such as George Bernard Shaw, H. G. Wells, and Sidney and Beatrice Webb, all leading members of the Fabian Society. He was also a member of the Coefficients dining club of social reformers.
