Ministerial Consolidation Proposal

Goal: Reduce Cabinet minister count by 20% (approx. 6 ministers) while preserving capability and statutory safeguards.

Approach: Combine high-overlap portfolios, cluster small niche roles into logical homes, and expand use of Associate Ministers and Parliamentary Under-Secretaries to carry operational load.


Recommended portfolio combinations

Finance + Economic Growth Align fiscal strategy with economic policy and Treasury/MBIE interfaces 1

Tertiary Education + Science Innovation & Technology Link research funding, skills pipeline and innovation policy 1
Arts Culture Heritage + Media Communications Consolidate cultural funding and public media policy 1

Further optimisations and clustering

Option Effect Mitigation
Use more Associate Ministers Reduces Cabinet headcount while preserving capacity Formal delegation of statutory powers and clear remits
Create Delivery and Infrastructure cluster Combine Transport, Housing, Infrastructure, Building, Consenting Appoint two Associates (consenting; delivery) to spread workload
Cluster small portfolios Fold Veterans, Space, Ethnic Communities, Child Poverty Reduction into larger ministries Maintain visibility via dedicated Associate or Minister for Community Affairs
Move Revenue under Finance Centralise tax and fiscal policy Preserve IRD statutory independence and reporting lines
Reduce ministers outside Cabinet Convert some outside-Cabinet ministers to Associate roles Negotiate role status with coalition partners as needed

Risks and mitigations

  • Workload concentrationMitigation: appoint strong Associate Ministers and Parliamentary Under-Secretaries with delegated responsibilities.
  • Statutory independenceMitigation: preserve legal reporting lines and independent commissioners where required.
  • Perceived downgrading of issuesMitigation: publish clear remits, maintain dedicated funding lines, and keep public reporting.
  • Political feasibilityMitigation: treat changes as administrative optimisation and negotiate with coalition partners.

Practical implementation steps

  1. Map statutory constraints — identify roles that must remain separate.
  2. Design clusters with Deputies — each merged portfolio gets at least one Associate Minister with delegated powers.
  3. Publish transition plan — timeline 3–6 months, delegated instruments, staff reassignments.
  4. Legislative checks — amend Acts that require separate ministerial warrants or reporting lines.
  5. Communications — explain continuity, safeguards, and benefits to stakeholders and the public.

Quick checklist for decision makers

  • Confirm current ministerial list and headcount with official DPMC source.
  • Identify statutory exclusions such as Attorney-General and independent offices.
  • Select 3–4 pilot merges to test the model before wider rollout.
  • Assign Associates and Under-Secretaries at the time of merger to avoid service gaps.
  • Monitor performance and publish a 12-month review on delivery and governance impacts.

Note: Treat the above as an administrative design template. Validate every proposed merge against statutory requirements and coalition agreements before implementation.
