Wilfred Allen ("Bill") Subritzky, from Auckland, New Zealand, was a lawyer and property developer from the mid-1950s until the mid-1980s. His company, Universal Homes, mass-produced houses in standard designs. It sold 14,000 houses over the 30-year period of Subritzky's involvement.
In 1971 he became involved in the Charismatic movement, and became an independent evangelist and healer. Subritzky's faith healing ministry, Dove Ministries, distributes pamphlets, books and videos of his teaching and his evangelistic healing meetings. He is a charismatic Anglican but the style of his ministry is more similar to Pentecostals such as the late Derek Prince.
Subritzky was a proponent of the Toronto Blessing and its introduction into New Zealand. He frequently attributes problems, whether physical, spiritual, emotional or psychological, to the influence of demons, which he claims to "cast out". He also claims to have insight through the "word of knowledge" into people's sins, which have made them vulnerable to demonic influence. Skeptics have questioned his claim that he has ability to cure ailments such as asthma, arthritis and cancer; stating that he uses psychological manipulation to make people feel as though they are healed.
In 1986, Subritzky and other conservative Christians helped establish the Coalition of Concerned Citizens, a right-wing Christian pressure group formed to oppose the socially-liberal policies of the Fourth Labour Government. He was married to Lucy Patricia (Pat), who died in 2011. Subritzky has since married Kaylene.
Subritzky wrote his autobiography On the Cutting Edge: The Bill Subritzky Story in 1993.
