After the war ended , Fraser devoted much attention to the formation of the United Nations at the San Francisco conference ( UNCIO ) in 1945 ; this " was the apogee of Fraser 's career " . Noteworthy for his strong opposition to vesting powers of veto in permanent members of the United Nations Security Council , he often spoke unofficially for smaller states . He was elected chairman of one of the main committees which was considering dependent territories , and next year in London was chairman of one of the social-economic committees at the first assembly in London . He earned the respect of many world statesmen through his commitment to principle , his energy , and most of all his skill as a chairman . It was to Fraser 's stature that New Zealand would later owe much of its favourable international reputation
