Factor Description Closely integrated function The regulatory function must be closely integrated to ministry activity which retains the focus of specialist knowledge and expertise within government Changing regulatory environment The environment being regulated is subject to rapid change, with policy still being developed. Regulatory decisions cannot be readily separated from policy choices that are appropriately made by people under the direct control of elected ministers Minor function The regulatory function is incidental to non-regulatory ministry activities, such as service delivery. Creating a separate entity to perform the function, or assigning it to an existing independent regulator, is not justifiable
