He then served as Counsellor at the New Zealand Embassy in Washington. While in Washington, in April 1973, the Black September group painted slogans on the wall of his house and fired several shots through the windows. This was thought to have been the first Islamist-based terrorist attack in the United States. From 1976 until 1980, he was New Zealand's High Commissioner in Singapore.

In 1980, he returned to Wellington to become Head of the Prime Minister's Department, where he served under both Rob Muldoon and David Lange's administrations.

In the 1999 Queen's Birthday Honours, he was appointed a Companion of the New Zealand Order of Merit (CNZM), for public services, lately as Secretary of Defence. In 2000 he chaired the Commonwealth Eminent Persons Group, which advised the Papua New Guinea Government on the reconstruction of its armed forces.
