Scott, who was hailed as "the complete full-back", played 54 times for the All Blacks, including 17 Test appearances, between 1946 and 1954.
Despite not making his international debut until the age of 25 due to World War II, Scott packed enough into his career to be inducted into the New Zealand Sports Hall of Fame in 1990.
"It is with great sadness we announce the passing of Bob Scott who was the oldest living All Black," New Zealand Rugby Union chairman Mike Eagle said.
"Bob was a much -dmired player, regarded by many as the complete full-back who played the game with passion and courage."
Scott was awarded an MBE in 1995 for services to sport.
