Police Powers and Responsibilities Act 2000

If the law enforcement officer to whom a retrieval warrant has been issued, or who is primarily responsible for executing a retrieval warrant, believes that the grounds for issue of the warrant no longer exist, the law enforcement officer must inform the chief executive officer of the law enforcement agency immediately.

If the chief executive officer of a law enforcement agency is satisfied, whether because of subsection (1) or otherwise, that the grounds for issue of a retrieval warrant to a law enforcement officer of the agency no longer exist, the chief executive officer must give written notice of that fact to the public interest monitor.

If notice is given under subsection (2) for a retrieval warrant, the warrant stops having effect.
