Metge was born in the
Auckland suburb of
Mount Roskill on 21 February 1930, the daughter of Alice Mary Metge (née Rigg) and Cedric Leslie Metge. She was educated at
Matamata District High School and
Epsom Girls' Grammar School. She went on to study at
Auckland University College, graduating
Master of Arts with first-class honours in 1952, and the
London School of Economics where she earned her PhD in 1958. As of 2004, she continued to advance peace initiatives via her work as a member of the
Waitangi National Trust Board, a conference presenter, adviser, and as a mentor to mediators and conflict management practitioners. A scholar on
Māori topics, she was recognised for promoting cross-cultural awareness and published a number of books and articles in her career. She likened the relationship among the people of New Zealand to "a rope [of] many strands which when woven or working together create a strong nation" (as paraphrased by
Silvia Cartwright). Metge died on 17 September 2025, at the age of 95. ==Honours and awards==
