Since then, she has sung for queens and princes - her voice beamed to more than 750 million viewers when she performed at Prince Charles and Lady Diana Spencer's wedding in 1981.
Two years later, she became the first New Zealander to win a Grammy Award, when she claimed the best opera recording prize in 1983.
Over the course of her five-decade career, she won countless awards and honorary degrees.

She has sung all the great operas with all of the greatest opera singers.
Last year, in an interview with the BBC, Te Kanawa announced she would never sing again.
