The Classification Office mainly deals with films, DVDs, video games and computer files. However it does occasionally classify or censor books and magazines.
Prior to the creation of the Office of Film and Literature Classification, the Indecent Publications Tribunal was the censorship authority for printed material.
Books do not have to be classified before they are supplied to the public in the same way that films do. Each year the Office classifies a number of books and magazines which are either submitted voluntarily or by an enforcement agency such as NZ Customs.
