Treaty co-governance implementation in Wellington

Wellington is the rohe of several iwi — principally Ngāti Toa Rangatira, Te Ātiawa, and Taranaki Whānui — whose Treaty rights and interests are relevant to environmental management, resource consenting, and cultural heritage. Co-governance arrangements are at varying stages of maturity across the Wellington region and are contested in parts of the public discourse.

Treaty co-governance implementation in Wellington

Analysis horizon: 10yr · 50yr · 100yr

Ngāti Toa settlement and scope

The Ngāti Toa Rangatira Treaty settlement (2014) established significant rights and interests across the greater Wellington region, including co-governance of parts of the Kāpiti and Marlborough coasts and cultural redress provisions. Implementation is ongoing (claim.wellington.governance.ngati_toa_settlement_scope).

Te Ātiawa and partnership arrangements

Te Ātiawa ki Whanganui-a-Tara has Treaty interests in Wellington Harbour and surrounding areas, and partnership arrangements with Wellington City Council and Greater Wellington are evolving in the context of the Whaitua freshwater process and resource management reform (claim.wellington.governance.te_atiawa_partnership_arrangements).

Drivers

The following structural drivers contribute to this problem.

Resource management reform and co-governance uncertainty

  • Category: institutional
  • Timescale: short
  • Consensus: contested

Treaty settlement implementation lag and capacity constraints

  • Category: institutional
  • Timescale: long
  • Consensus: mostly-agreed

Solution camps

A number of distinct positions recur in policy debates on this issue. Each is defensible on its own terms; none is obviously correct. Presented in alphabetical order without ranking.

Practical Treaty Partnership in Service Delivery

Contracting Māori providers to deliver services to Māori communities and embedding tikanga in council processes is more achievable than structural co-governance.

Flagship moves:

  • Preferential procurement for iwi social service providers in Wellington
  • Tikanga Māori protocols embedded in planning processes
  • Iwi cultural impact assessments as standard component of resource consents

Tensions:

  • Service delivery partnership without governance power is insufficient for Treaty obligations
  • Iwi capacity to take on service delivery contracts varies significantly

Interventions on the system:

  • Require cultural impact assessment from mana whenua for all Wellington City Council infrastructure consents (state variable: iwi_participation_in_decisions, sign: +)

Treaty Co-Governance Implementation

Meaningful Treaty co-governance with Ngāti Toa, Te Ātiawa, and other mana whenua across Wellington’s resource and planning decisions fulfils Treaty obligations and improves outcomes.

Flagship moves:

  • Establish statutory co-governance arrangements for Wellington Harbour under RMA
  • Mana whenua seats on Wellington Water governance board
  • Treaty audit of all Wellington City Council bylaws and planning instruments

Tensions:

  • Co-governance raises questions about democratic accountability in a one-person-one-vote framework
  • Multiple iwi with overlapping rohe in Wellington creates complexity in determining mana whenua representation

Interventions on the system:

  • Establish Wellington Harbour co-governance entity with equal mana whenua and council representation under RMA s.33 (state variable: treaty_cogovernance_implementation_score, sign: +)
