Consistency Accountability Statements (CASs), Summary of Underpinning Analysis, and Minister/Maker Statement of Reasons

For new legislation, the following documents are required to be submitted to the Minister, Cabinet, included in the Explanatory Note to a Bill or Regulation and published on the agency website:

  • Consistency Accountability Statement (CAS)
  • Summary of Underpinning Analysis
  • Minister/Maker Statement of Reasons

A Consistency Accountability Statement (CAS) is a statement from the chief executive of the responsible agency which confirms that the agency has reviewed the proposed legislation against a set of principles of responsible regulation. The principles are listed in Section 9 of the Regulatory Standards Act 2025.

A Summary of Underpinning Analysis shows that the proposals have been tested against the principles. 

A Minister/Maker Statement of Reasons is required if an inconsistency has been identified.

Together, these accountability documents provide information on whether proposed legislation is consistent or inconsistent with the principles of responsible regulation and explain the reasons where inconsistencies are identified.

Additional information about CAS can be found on the Ministry for Regulation website at Consistency assessments for new legislation
