Department of the Prime Minister and Cabinet (NZ), Security in the Government Sector (SIGS) (Dec. 18, 2002) (full-text).
The Official Information Act 1982 espouses the principle that official information should be made available to the public unless there are good reasons to withhold it. However, the Government requires that official information receives appropriate protection where it is in the national or public interest to do so.
This document, authorized by the Interdepartmental Committee on Security and published in 2002 by the Department of Prime Minister and Cabinet, replaces "Security in Government Departments" issued in 1994, and incorporates the revised security classification system approved by Cabinet on December 18, 2000.
SIGS is designed to help government departments and agencies, State Owned Enterprises and Crown Entities develop their security instructions based on a framework that is consistent throughout the Government sector.
