Anthony Edward Charles Rayner (born 19 November 1952) is a New Zealand musician who spent ten years as a keyboardist in the band Split Enz.
Rayner has also produced material for many artists including Models, Margaret Urlich, Rikki Morris, Margot Smith, and The Exponents, as well as two Enzso recordings with Split Enz members, Dame Kiri Te Kanawa and the New Zealand Symphony Orchestra.
Recently he has acted as musical director for television show New Zealand Idol, and participated in reunions of Split Enz and Space Waltz.
He has also recorded with Double Life, whose other members are guitarist Adrian Stuckey, Mark Dennison (sax, flute and clarinet), and drummer Patrick Kuhtze.
The resulting album, Shades and Echoes, used elements from early Split Enz songs combined with Rayner's jams with Double Life.
