Jenkin (2011) — Rainbow and Tui: brief histories
The second independent source for Tui's 50 ha — and the batch's clearest evidence that community food production regresses
An insider history of two Golden Bay intentional communities, built on 12 interviews. Tui: verbatim “Tui has fifty hectares. Roughly half is flat” — the corroboration that, with URL_029, justified correcting the wiki from 72 ha. Population “closer to fifty”; ~30 members (8 NZ-born, 22 overseas); 20 trustees + 25 non-members. 🔻 “Achieving that has meant important changes such as scaling back the Tui garden and employing a fulltime grounds-man.” Rainbow Valley: 103 ha bought 1974 for $25,000 (26 ha flat, 37 ha bush/gorse, 40 ha steep forest); 9 members + 10 non-members. 🔻 “Rainbow’s farm has never been financially profitable, but it has provided milk, mutton and beef.”
Summary
A short history of Rainbow Valley Community and Tui Community, two long-running intentional communities in Golden Bay, written from the inside and drawing on twelve interviews. It covers founding, land purchase, membership structure, governance and the evolution of each community’s productive activity through to 2011.
It contributes two things to the corpus. First, it is the independent corroboration of Tui’s land area that, together with the community’s own site, was sufficient to correct a wiki figure — a rare event. Second, and more interesting for the thesis, it contains two sentences that document decline in community food production: Tui scaled back its garden, and Rainbow’s farm was never financially profitable. Read alongside OT_190’s finding that not one surveyed household was fully self-sufficient and only 8% were self-sufficient in two or more food types, the picture that emerges across this batch is that community food self-sufficiency regresses rather than accumulates.
Key claims
- claim: "🔴 TUI LAND AREA — THE SECOND INDEPENDENT SOURCE. Verbatim: 'Tui has fifty hectares. Roughly half is flat.' This corroborates the community's own site (URL_029, 'a farm consisting of 50 hectares (125 acres)') against LIT_015's 72 ha, and is the second of the two agreeing sources that justified correcting the wiki. [verified verbatim against the PDF]"
source_location: "Jenkin (2011), Rainbow and Tui brief histories — Tui land description."
- claim: "TUI MEMBERSHIP AND POPULATION (2011): population 'closer to fifty'; approximately 30 members, of whom 8 are NZ-born and 22 overseas-born; 20 trustees plus 25 non-members. [verified verbatim against the PDF]"
source_location: "Jenkin (2011), Rainbow and Tui brief histories — Tui membership."

- claim: "RAINBOW VALLEY: 103 ha bought in 1974 for $25,000, comprising 26 ha flat, 37 ha bush/gorse and 40 ha steep forest; 9 members plus 10 non-members. [verified verbatim against the PDF]"

Feeds tui_community as the corroborating source for the land-area correction, and contributes a cross-batch thesis finding.
1. The corroboration (its NI function). Two independent sources stating 50 ha — this one and URL_029 — against one academic secondary stating 72 ha, on a 31% discrepancy, with the acre/hectare pair reconciling internally. That is what met the bar for changing land_area_ha on tui_community. Neither source alone would have.
2. The regression finding (its thesis function). Across this batch, four independent observations point the same way:
| Observation | Source |
|---|---|
| Tui scaled back its garden and employed a full-time grounds-man | OT_192 |
| Rainbow’s farm “has never been financially profitable” — though it did provide milk, mutton and beef | OT_192 |
| ”Not one household was completely self-sufficient in all of the food types”; only 8% in two or more | ot_190_brct-2015-blueskin-karitane-foodshed |
| Zero commercial production of fruit, vegetables, grains or beverages in a 2,800-person foodshed | ot_190_brct-2015-blueskin-karitane-foodshed |
🎯 Community food self-sufficiency regresses rather than accumulates. The batch’s case evidence shows no example of a NZ community increasing its food self-sufficiency over time, and two explicit examples of contraction. This is a thesis-level finding, and it is a caution against any NI output that presents food SSI as a target a community will grow into. It also aligns with LIT_077’s theoretical-overstates-actual caveat and LIT_012’s Auroville finding (15% internal food supply despite available arable land).
3. Rainbow Valley’s land composition is a usable structural datapoint. 103 ha as 26 ha flat / 37 ha bush-gorse / 40 ha steep forest — i.e. only 25% of the holding is flat. Community land purchases are cheap partly because most of the land is not productive. Any model that reads a community’s total hectares as available food land will overstate capacity by roughly 4× on this example.

Notes
data_quality: medium, assigned at commit. The approved verification draft did not specify adata_qualityfor this source.mediumreflects an insider history built on twelve interviews: strong on facts the communities know about themselves (land area, membership, purchase price), unaudited and potentially partial on judgements.contested: true/contradictions: [LIT_015]— this source contradicts LIT_015’s 72 ha for Tui. The contradiction is now resolved in this source’s favour; the flag is retained so the disagreement stays visible.- Rainbow Valley was NOT given its own case page. It appears in one source and occupies roughly half of it — borderline against the page-creation threshold (≥2 sources, or central to one). The approved draft did not propose a page, so its data is recorded here. If a second Rainbow source ever lands, create the page then. ⚠ Flagged for the user’s decision.
- The $25,000 for 103 ha in 1974 is a striking community-finance datapoint but is not de-datable with anything in corpus, and is recorded as history rather than as an input.
- 2011 vintage — the same year as LIT_015, and it is the newest Tui membership data in corpus. Tui’s own site (URL_029) does not update the population figure.

Research targets
Documents to retrieve
- (none) — this is a primary insider history; nothing it cites would advance the model.
Research gaps
- Not raised as RTs (recorded here instead, per the batch’s minimise-new-RTs decision):
- Why Tui’s garden was scaled back. The single most interesting unanswered question in the case lane: whether the cause was labour, economics, membership change, or preference determines whether it is a design lesson or a local accident. Not answered here.
- A current (post-2011) Tui membership and population figure. Would matter for the RT_331 density work; the site visit already in the project’s pipeline is a better route than retrieval.
- Rainbow Valley as a case. See Notes — deliberately not created as a page on one source.
