IwiData publishes machine-readable data on 108 iwi and post-settlement governance entities in Aotearoa New Zealand — treaty settlements, annual financial history, commercial subsidiaries and asset portfolios. This page is the integration guide. Everything below is free, anonymous and rate-limited per IP; there is no key to request.
Data sovereignty — read this first
Iwi data is a taonga. IwiData republishes information that iwi and Crown agencies have already made public, and recognises that authority over Māori data rests with Māori. Our machine-readable surface is governed by the Te Mana Raraunga principles and the CARE Principles for Indigenous Data Governance.
Three things follow, and they are conditions of use rather than sentiment:
- No individual is named in any endpoint on this page. Iwi officer names, roles and governance fees are deliberately excluded from machine-readable republication. Board size is available as a count.
- Any iwi may opt out of machine-readable republication. When one has, these endpoints return 404 with the reason stated. Honour it — do not fall back to scraping the HTML page.
- Settlement figures are not a league table. They are nominal dollars at the date of settlement, and are not a measure of loss or of present-day wealth. Ranking iwi by settlement quantum without accounting for date, population and the nature of the claim produces a misleading answer.

Endpoints
| Path | Type | What it returns |
|---|---|---|
| /api/v1/iwi/{slug}/summary.md | text/markdown | Prose summary of one iwi — identity, rohe, treaty settlement, financial history, commercial subsidiaries, asset portfolio, board size. Names no individual. |
| /api/v1/iwi/{slug}/facts.json | application/json | The same facts as structured JSON, with a citation array and explicit NZD units. Names no individual. |
| /api/v1/iwi/{slug}/settlement.md | text/markdown | Treaty settlement detail — quantum, financial redress, cultural redress quoted verbatim, and the Act that gave it effect. Cites Te Arawhiti above us. |
| /sitemap/iwi-entities.xml | application/xml | Every iwi entity URL, with lastmod driven from the real MAX(updated_at) of the backing table rather than the current date. |
| /llms.txt | text/plain | Topic taxonomy and primary URLs for this domain. |
Full URLs are https://iwidata.co.nz + path. {slug} is the iwi slug used on https://iwidata.co.nz/iwi-entities, e.g. ngai-tahu. Rate limit is 60 requests per 10 minutes per IP; the response carries the remaining budget in its headers.
Example
curl -s https://iwidata.co.nz/api/v1/iwi/ngai-tahu/summary.md curl -s https://iwidata.co.nz/api/v1/iwi/ngai-tahu/facts.json | jq .treaty_settlement
What is behind the endpoints
Data is compiled from sources that are already public: the iwi’s own annual reports, the New Zealand Charities Register, the Companies Office, Te Puni Kōkiri’s Te Kāhui Māngai and settlement legislation. Every response carries a citation array naming those sources, with the Crown source listed above us — for treaty data, Te Arawhiti is authoritative and we are a bridge to it.
Coverage is partial and stated rather than hidden: financial statements are held for 77 of 108 entities. Where we hold nothing, the endpoints say so explicitly instead of returning a zero. An absent settlement record means we have not extracted one — not that none exists.
