Diplomat Terence O’Brien was at the centre of New Zealand’s foreign relations for nearly half a century, forging new ties with Asia, negotiating New Zealand’s market access to what became the European Union, or running the first successful campaign for a seat on the United Nations Security Council.

His new post-humous memoir, Consolations of Insignificance, comes out next month. His son, Diplosphere co-founder Dan O'Brien, joins Thomas to discuss his father's life in public service, and how some of his battles reflect our current foreign policy concerns.
