This Is Your Life is a New Zealand television documentary show based on the American show of the same name, in which the host surprises guests with a show documenting their lives, with audience participation from their friends and family. Prior to that, the last This Is Your Life programme in New Zealand was broadcast in September 2000. The subject of that episode was the great New Zealand runner, Peter Snell. The show has also featured iconic New Zealanders such as mountaineer and explorer Sir Edmund Hillary and Māori activist Dame Whina Cooper.
