Body was also an advocate for New Zealand music and composers. In 1975, Body released a three-LP set of New Zealand electroacoustic music, "New Zealand Electronic Music" (Kiwi-Pacific LP, SLD 44–46), realised in the electronic music studios of Victoria University. In subsequent years he would edit over twenty CDs of New Zealand music. In 1981, at Douglas Lilburn's behest, Body re-activated the then-dormant Wai-te-ata Music Press, a publisher of New Zealand musical scores which Lilburn had founded. Body was editor of Wai-te-ata Music Press from 1981 to 2013, during which time the press became the largest publisher of New Zealand music. Body founded the Nelson Composers’ Workshop in 1982, an ongoing annual gathering of young, emerging and established New Zealand composers where new works are performed and critiqued.
