River consents and Treaty partnership
Waikato Regional Council is hearing a 35-year application from a dairy processor to take up to 18 million cubic metres of water a year from the lower Waikato River. The catchment plan gives effect to Te Mana o te Wai and includes a negotiated iwi participation arrangement with the local hapū authority, Ngāti Kōwhai. The hapū says the proposed minimum flow would expose tuna habitat and a wāhi tapu near the intake. It also says the company's consultation was two letters and one hui attended by no senior manager. The company points to 420 local jobs and a $9 million annual regional spend. There are 240 submissions: 80 oppose, 35 support, and 125 are neutral. The hearing panel has three commissioners, one appointed jointly with the hapū, and must decide in six weeks. The council's hydrologist says the proposed flow is within the plan's numeric minimum, but the plan's cultural-values chapter says nothing specific about wāhi tapu. The hapū has not filed a Waitangi Tribunal claim.
1. Which Treaty principles and Resource Management Act 1991 provisions should the panel treat as decisive, and how should it weigh them against the 420 jobs?
Read the worked answer
The starting point is not a free balance between jobs and culture. Section 6(e) of the RMA makes the relationship of Māori with ancestral water and wāhi tapu a matter of national importance; section 8 requires the panel to take into account Treaty principles. The plan's Te Mana o te Wai framing gives water health priority, so the panel must ask whether the proposed flow sustains the river's values, not merely whether it exceeds a numeric minimum. Treaty principles require partnership, active protection, and informed decision-making. That means the panel should give real weight to the hapū's evidence, ask for a cultural impact assessment, and consider conditions such as a higher minimum flow, a wāhi tapu exclusion area, and independent monitoring with hapū input. The 420 jobs and $9 million spend are relevant economic effects under section 104, but they do not automatically outweigh Treaty matters. A lawful decision would record how the panel weighed them and why any residual adverse effects are acceptable. Two letters and one junior hui are unlikely to satisfy good faith consultation, but the panel can cure some gaps through the hearing process.
2. If the panel grants the consent, what can Ngāti Kōwhai realistically do, and what limits apply to each path?

Ngāti Kōwhai's first realistic route is an appeal to the Environment Court on the merits within 15 working days of the decision. The court can rehear evidence, uphold, vary, or cancel the consent, so this is the strongest route. Judicial review in the High Court is narrower: it asks whether the panel acted lawfully and fairly, not whether the decision was wise. A Waitangi Tribunal claim would have to frame the issue as a Crown act or policy; the Tribunal can inquire and recommend, but it cannot simply quash a council resource consent, and urgency is discretionary. Political and mediation routes also matter: the hapū can seek conditions, monitoring, or a review of the iwi participation arrangement. The limits are practical: appeals are costly and time-limited, and the consent may still operate while challenges proceed unless a stay is granted.
