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.

Thirty-nine New Zealanders have been honoured in the New Zealand version of the show, which has been broadcast on and off since 1984 on Television New Zealand's TVOne. It was originally hosted by Bob Parker, but more recent episodes have been presented by Paul Holmes and Paul Henry. Most recently, racecar driver Scott Dixon was honoured, on 21 September 2008. Other recent recipients have included extreme sports pioneer, A. J. Hackett. Mark Inglis, the subject of an episode that was broadcast on 5 June 2007, and former All Blacks winger Jonah Lomu, who was honoured in a show that aired on 9 April 2007.

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.

Previous subjects of the show have included prominent figures in sports, the arts, politics, broadcasting, literature, science and the military.
