It's gone by many names and structures over the years: Department of External Affairs, Ministry of Foreign Affairs... and now MFAT.
The origin and evolution of the agency responsible for this country's international relations has been captured in a new book: New Zealand's Foreign Service: A History.
It looks at the early years - with the role World War II played in its creation in 1943 and the key players who shaped it, to the way it responded to strategic events - like Britain strengthening ties with Europe, the breakdown of ANZUS and the war on terror.
It also considers the internal changes to the organisation over the years - from one dominated by Pakeha men to one that was much more inclusive. Dr Ian McGibbon wrote the early chapters and has edited the book.
He joins Kathryn to explain how the organisation has played a vital role in New Zealand's history.
