Regulatory impact assessments

A RIA provides a high-level summary of the problem being addressed, the options and their associated costs and benefits, the consultation undertaken, and the proposed arrangements for implementation and review.

Regulatory Impact Assessment (RIA)

To help ensure that the regulatory process is open and transparent, RIAs prepared to support the consideration of regulatory proposals are published at the time the relevant bill is introduced to Parliament or the regulation is gazetted, or at the time of Ministerial release

The RIAs are published on the responsible department's website, and here on the Treasury website.


Cabinet changed the Regulatory Impact Assessment (RIA) requirements, including the form in which Regulatory Impact Analysis is published, as of 30 June 2017. The transition period ended on 7 August 2017.

See Impact Analysis for Regulatory Proposals for further details of the changes.

RIAs authored by the Treasury are usually available in HTML and Adobe PDF formats. RIAs authored by another agency will be provided in Adobe PDF format with a link to where the RIA is available on the agency's own website.

RIAs are listed in chronological order according to the date the related bill was introduced to Parliament or the related regulations were gazetted, or the time of Ministerial release.
