Review of legislation including reference to the principles of the Treaty of Waitangi

The Government has completed its review of provisions in legislation that reference the principles of Tiriti o Waitangi/Treaty of Waitangi and made decisions on next steps.  

The review was part of the Coalition Agreement between the National and New Zealand First parties. The agreement included a commitment to a review of all legislation that includes “the principles of the Treaty of Waitangi” and either replace the reference with specific wording that explained the relevance and application of the Treaty principles or to remove them.  

This review was not related to the Treaty Principles Bill previously before Parliament.  

How was the review undertaken? 

The Ministry of Justice supported the Minister of Justice, Hon Paul Goldsmith, who led the review.  

The review was overseen by a Ministerial Oversight Group which consisted of the Minister of Justice, the Attorney-General, initially Hon Judith Collins KC, and then Hon Chris Bishop, the Minister for Regional Development, Hon Shane Jones, and the Minister for Māori-Crown Relations, Hon Tama Potaka.   

The Ministerial Oversight Group was assisted by a Ministerial Advisory Group, that consisted of four members with expertise in Māori issues, economic development, governance, and the Treaty of Waitangi. The members of the Ministerial Advisory Group were David Cochrane (Chair), Marama Royal, James Christmas, and John Walters.  

Timeline

24 November 2023: National-New Zealand First coalition agreement signed which includes a commitment to: “Conduct a comprehensive review of all legislation (except when it is related to, or substantive to, existing full and final Treaty settlements) that includes ‘The Principles of the Treaty of Waitangi’ and replace such references with specific words relating to the relevance and application of the Treaty or repeal the references.” 

September 2024: Cabinet agreed to a review of legislation that includes references to the principles of the Treaty of Waitangi. Cabinet agreed the purpose of the review was to ensure that ‘where it is appropriate to encapsulate te Tiriti o Waitangi/the Treaty of Waitangi or the Treaty relationship in legislation’, provisions are ‘clear about how the Treaty applies.’  The review initially covered 28 Acts managed by 13 agencies.  

May 2025: Cabinet agreed to establish a Ministerial Advisory Group, and a Ministerial Oversight Group. The scope was refined to 23 Acts managed by 13 agencies. At this time Cabinet also include section 127(1) of the Education and Training Act 2020 in the review. 

July 2025: The Minister of Justice confirmed all Treaty-related provisions in the Education and Training Act would be included in the review. 

August 2025: The Ministerial Advisory Group reported to the Ministerial Oversight Group. 

October 2025: Cabinet agreed that section 127 of the Education and Training Act be amended through the Education and Training Act Amendment Bill (No 2) at the Committee of the Whole House stage. 

February 2026: Cabinet made policy decisions and invited the Minister of Justice to issue drafting instructions (see Review outcome below) with a final scope of 19 Acts managed by 11 agencies.  

April 2026: The Minister of Justice wrote to the National Iwi Chairs Forum seeking to engage on the proposed changes before legislation is introduced to Parliament and referred to a select committee for public submissions.

February 2026:  Following consideration of the Advisory Group’s report by the Oversight Group, Cabinet decided on 23 February 2026 to:

  • amend references within the final scope of the review so that in situations where a Treaty standard is needed, no higher standard than “take into account” is used. “Treaty standards” indicate the strength or nature of the Crown’s Treaty obligation. Cabinet’s decision means that in instances where stronger standards like “give effect” are used, this would be replaced with “take into account”. 
  • replace broad provisions with descriptive provisions. The proposal to make provisions more specific applies to section 8 of the Hazardous Substances and New Organisms Act 1996, and section 14(a) of the Data and Statistics Act 2022. 
  • standardise the drafting of provisions, including by ensuring a reference to both the Treaty of Waitangi and te Tiriti o Waitangi is used in all instances.  Standardisation changes are drafting amendments that do not affect the underlying policy of each Act.

  • Repeal several provisions, two of which duplicate other provisions in the same Acts. The provisions proposed for repeal are:

  1. Section 84(b) of the Crown Pastoral Land Act 1998
  2. Section 536A(1) of the Education and Training Act 2020
  3. Section 6(d) of the Energy Efficiency and Conservation Act 2000 
  4. Sections 4 and 5(1)(b) of the Organic Products and Production Act 2023
  5. Section 54 of the Plant Variety Rights Act 2022
  6. Section 3AB of the Smokefree Environments and Regulated Products Act 1990. 

Cabinet also agreed that the Minister of Justice would engage with the National Iwi Chairs Forum on Cabinet’s decisions prior to a Bill being introduced to Parliament and referred to a select committee for public submissions. 

Final decisions

On 14 September 2026, Cabinet approved three omnibus bills for introduction.  They are: 

  1. References to Te Tiriti o Waitangi/Treaty of Waitangi (Standardisation) Amendment Bill(external link) imposes a standardised rafting approach to descriptive Treaty provisions and references to the Treaty of Waitangi l Te Tiriti o Waitangi without substantively changing their legal effect.

  2. References to Te Tiriti o Waitangi/Treaty of Waitangi (Strength of Legislative Obligations) Amendment Bill(external link) amends the weighting of Treaty standards to “take into account” in various operative Treaty provisions.

  3.  References to Te Tiriti o Waitangi/Treaty of Waitangi (Repeals) Amendment Bill(external link) repeals references to the Treaty in various Acts.  

Cabinet did not agree to proceed with amendments to the Hazardous Substances and New Organisms Act 1996. 

Cabinet also agreed to exclude three purpose provisions of the Education and Training Act 2020 from the review (section 4(d), 32(h) and 3989B). 

The review is being progressed through three omnibus Bills because a single Bill covering the full review would not meet Standing Orders requirements for omnibus legislation. Each Bill deals with a set of related amendments that can be regarded as implementing a single broad policy. 

Glossary

Descriptive provisions specify how the Treaty (or its principles) is provided for in an Act by cross-referencing other provisions that operationalise and reflect Treaty obligations. 

Operative provisions are provisions requiring Treaty principles to be considered or given effect in applying an Act. Operative provisions are described as “general” when they apply to all decisions or functions in an Act, or “specific” when they relate to a specific action or by specified persons.
