	On retiring from the Court of Appeal, Turner joined the legal publisher Butterworths of New Zealand as a director and editor-in-chief, a post he was active in until shortly before his death. In his 70s and 80s, he updated a series of textbooks originally written by George Spencer Bower in the early years of the 20th century: "Actionable Misrepresentation" was published in 1974 and " by Representation" in 1977. The last of these, "The Law of Actionable Non-Disclosure" (which Turner co-authored with Professor R.J. Sutton) was published in 1990 when Turner was 88.
