Treaty Settlements · Part 05 · Fiscal envelope and relativity ledger

What do the 17% and 16.1% relativity clauses actually measure?

The relativity mechanisms are not percentages of New Zealand, Crown assets or total historical loss. They are contractual accounting mechanisms designed to preserve the relative size of the Waikato-Tainui and Ngāi Tahu settlements against a defined pool of historical Treaty settlement redress.

1. Start with the fiscal envelope

The Crown's 1990s Settlement Envelope policy proposed that $1 billion in 1994 dollars be available for historical Treaty settlements over about ten years. The policy was strongly opposed by many Māori and was abandoned as an overall fiscal cap in 1996.

Abandoning the cap did not erase the bargains already negotiated around it. Waikato-Tainui and Ngāi Tahu had secured relativity mechanisms precisely because they were settling early and did not want later settlements to leave their own packages relatively diminished.

2. Waikato-Tainui: 17%

The 1995 Waikato-Tainui raupatu settlement provided $170 million of redress and attached a relativity mechanism. In simplified terms, once the present value of total qualifying historical Treaty settlement redress exceeded the $1 billion threshold, Waikato-Tainui could claim further redress sufficient to preserve its agreed relative position at 17%.

The operative wording is not an ownership formula. It is an accounting formula applied to Crown settlement expenditure.

3. Ngāi Tahu: 16.1%

Section 18 of the 1997 Ngāi Tahu Deed defines the “Agreed Relativity Percentage” by dividing the real value of the Ngāi Tahu redress amount by $1 billion. The mechanism then requires further payment if the present value of total qualifying historical redress exceeds the threshold and Ngāi Tahu's real-value redress would otherwise fall below that agreed percentage.

The deed uses CPI, Government Stock rates, corporate tax assumptions, deemed receipt dates and annual Crown financial-statement figures to translate later redress back into the agreed base-value framework.

4. What actually counts in the Ngāi Tahu calculation?

The deed's definition of “Claim Redress Amount” is unusually important. For a historical claim, it generally takes the greater of the Crown expense recognised in its financial statements and the redress amount recorded in the settlement instrument, subject to detailed exclusions.

The deed also states a substantive test: a transfer of value is treated as historical claim redress where it is given in consideration of, or contingent upon, settlement of a historical claim. By contrast, expenditure reasonably characterised as “good government” rather than historical Article II redress is excluded.

5. The early settlement pool expressly reaches beyond land settlements

The Ngāi Tahu deed deems the redress for the 1992 fisheries settlement, Waikato's $170 million redress, and other historical claims settled between 23 September 1992 and 30 June 1995 to have been provided on 31 December 1994 for the relativity calculation.

This is a crucial point. “Total Treaty settlements” in the relativity mechanism is not shorthand for all government spending on Māori and it is not merely a list of iwi land settlements. It is a defined contractual category of redress for historical claims.

6. The Crown calculates every year; claims are constrained by time

Under the Ngāi Tahu deed, the Crown must calculate the relevant total annually through 2044. Ngāi Tahu can dispute a calculation within the deed's specified time limits and can make a claim for further redress if the threshold and formula are satisfied.

The deed permits more than one claim, but generally prevents another claim within five years of the calculation giving rise to a payment. It allows claims through 2044. Government material has commonly described the practical cycle as five-yearly relativity claims.

7. The mechanism has been triggered and is still live in 2026

Treasury's Budget 2026 supplementary information continues to disclose the relativity clause as a fiscal risk. It records that total historical settlement redress has exceeded $1 billion in 1994 present-value terms and that the Crown remains liable to maintain the agreed proportions of 17% for Waikato-Tainui and 16.1% for Ngāi Tahu.

8. The payment ledger through December 2025

Te Tari Whakatau published updated relativity-payment records in December 2025. They show both the regular five-yearly payments and additional payments arising from arbitrations or negotiated dispute resolutions.

Totals are arithmetic sums of the payments listed in Te Tari Whakatau's December 2025 public records. They are relativity-related payments, separate from the original settlement redress.

9. Why are there arbitration payments?

The public records say the Crown and both iwi have disagreed over what should be included in the total Treaty-settlement calculation. Six arbitration hearings had occurred by December 2025, with decisions going both ways. The arbitration awards themselves remain confidential, but the parties have published the resulting payment amounts.

That tells us the definition of “redress” is not merely theoretical. Classification decisions can change the Crown's liability by millions of dollars.

10. What the mechanism does not prove

11. Why this matters for the wider investigation

The relativity architecture reinforces Part 04's finding. The settlement system was constructed around negotiated redress relativity, not full-loss accounting. Even the safeguard given to the two early large settlements protects their position relative to later settlement redress, not relative to the actual economic value of everything historically lost.

Part 05 finding

The fiscal envelope and relativity mechanisms are financial architecture for settlement finality, not a valuation of sovereignty or ancestral rights. The $1 billion cap was abandoned in 1996, but Waikato-Tainui and Ngāi Tahu retained deed-based rights to maintain their original settlements at agreed proportions of the defined historical Treaty settlement redress pool. The deeds contain detailed inclusion, exclusion, valuation, timing and dispute rules. Those contractual rights remain fiscally operative in 2026.
