You need to know what happens when a law changes. When the Search and Surveillance Act 2012 came into effect, it changed some things about the Crimes Act 1961. This change affects things that were happening under Part 11A of the Crimes Act 1961 before 18 April 2012. You might be wondering what happens to applications that were made under Part 11A before 18 April 2012. If an application was made before that date but not finished, the old rules still apply to that application. This means the old rules apply to anything related to the application. There's something called a continuing warrant or permit. This is an interception warrant or emergency permit issued under Part 11A of the Crimes Act 1961. If you had one of these before 18 April 2012, or if you applied for one before that date and got it after, the old rules still apply to it. The old rules also apply to anything related to the warrant or permit, except for <a href=https://legislation.govt.nz/act/public/1986/0120/latest/link.aspx?id=DLM330968>section 312F. Some private communications were intercepted before 18 April 2012. The old rules, specifically <a href=https://legislation.govt.nz/act/public/1986/0120/latest/link.aspx?id=DLM330994>section 312M, still apply to those communications. This means the new law does not change how those communications are handled. A continuing warrant or permit is one that was issued before 18 April 2012, or one that was applied for before that date and issued after.
