Documents released under the Official Information Act 1982 can have some of their contents withheld for a variety of reasons. In August 2011 Cameron Slater, who writes a blog called 'Whale Oil', applied under the act for SIS documents dealing with Israeli visitors to Christchurch the previous year, after suggestions that they may have been spies. Some of those documents were released with their contents heavily 'redacted' (edited to withhold information that 'would reveal the sources and methods used in the investigation and would be likely to prejudice security').
