Philip Spencer Trusttum ONZM (born 9 June 1940) is a leading New Zealand figurative expressionist artist. His works are usually large-scale, energetic, and colourful works on unstretched canvas. Trusttum was born in Raetihi, in the central North Island, in 1940 to William and Katherine Trusttum. His father was a Methodist lay preacher, but he became disillusioned with his religious work and in 1945 the Trusttum family left for Christchurch, where Philip attended . The family moved to Oxford in 1948, and again to Rangiora in 1955 and to nearby Ashley in 1957.
