The Indecent Publications Tribunal (IPT) replaced the Customs Committees in restricting and banning books, magazines, and sound recordings. This took away the censorship of printed material from the hands of individual public servants and government Ministers.
Under the IPT, decisions on restricted or banned material were made a by a five person committee of which at least two members had specialist qualifications in literature or education. The Chair of the IPT was always a judge or experienced lawyer. Decisions were made by vote and were published in the New Zealand Gazette. The IPT could only classify material that was submitted to it either by publishers, members of the public or government agencies (mainly Customs). The majority of magazines it classified were sexually explicit magazines for adults. They also classified a large number of weapon and drug manuals.
Decisions of the IPT remain in force today unless they have been overturned by a more recent decision of the Office of Film and Literature Classification.
