        "body": "This strand exists because cooling is a freshwater question and New Zealand has almost no data about it. The entire public evidence base for data-centre water draw in this country is one consent: Datagrid's Makarewa site in Southland — 280 MW, roughly NZ$2 billion, phase one targeted around 2028 — consented to draw 220 million litres of groundwater a year for cooling, with full consent still pending [S-14]. On the other side of the ledger, Microsoft's Auckland region runs water-free cooling [S-15] — proof the technology choice exists. There is no per-facility water-draw disclosure standard of any kind [G-7]. Consenting runs through the RMA, council by council. — Aroha Simmons (chair)",

        "body": "The freshwater scientist's opening, and it is mostly about how little we know. One number exists in public: Datagrid Makarewa, consented for 220 million litres of groundwater a year for cooling a 280 MW facility, consent process still running [S-14]. That number is public only because the consent process forced it into the open — it is not disclosure policy, it is a by-product. Everything else is inference. And here is the part I will keep repeating until it is in the draft: water is not a national quantity. 220 million litres is trivial against a national water budget and potentially significant against one aquifer's sustainable yield in one catchment in Southland. Any policy sentence that speaks about data-centre water nationally is speaking about nothing. Catchment is the unit of analysis. The draft must be written that way or it will be hydrologically illiterate.",

        "body": "The council planner's reality check. When a hyperscale cooling consent lands on a regional council's desk, the applicant brings thermodynamic modelling, proprietary cooling specifications, and consultant hydrogeology. The council brings, if it is lucky, one consents officer who last saw a heat-rejection calculation at university. Consenting runs through the RMA with all its council-by-council variability, and the resource-management system is mid-replacement, which adds transition uncertainty on top [S-14]. My point is institutional, and it cuts across Aroha's: yes, catchment is the unit of analysis — but forty-odd consent authorities cannot each independently develop the technical capability to interrogate data-centre cooling claims. Without national guidance — a standard assessment methodology, reference cooling technologies, model consent conditions — we will get forty different answers of forty different qualities, and the applicants with the best consultants will win regardless of the water.",

        "body": "The primary-sector seat, and I will say what farmers around Makarewa are already saying: that aquifer has existing users. Two hundred and twenty million litres a year [S-14] is not being drawn from spare water — in most productive catchments there is no spare water; there is allocated water, over-allocated water, and ecological minimum flows already under pressure. When a NZ$2 billion facility [S-14] arrives seeking groundwater, it arrives into a queue — dairy sheds, irrigation takes, town supply — except capital that size does not usually queue; it hires its way to the front. My requirement for this strand is allocation precedence, stated in plain terms: existing lawful users and ecological flows come first, and a new industrial take in a stressed catchment must show its water is genuinely available, not just consentable. If that means some data centres pick different sites or dry cooling, good — that is the system working.",

New Zealand has no per-facility water-draw disclosure standard for data centres — no requirement that facilities report what they take, from where, at what seasonality, against what catchment state [S-14][G-7]. The single Datagrid figure exists as a consent artefact, not as policy [S-14]. So this strand faces the same structural choice the electricity team hit with their forecasting gap: we cannot regulate what we cannot see, and the honest first instrument is the one that creates the missing data. A disclosure standard — per-facility, per-source, published, feeding regional council allocation accounting — is the foundation. Gerald's national guidance needs it, Mere's precedence rules need it, and my catchment-by-catchment assessment needs it. Nothing else this strand proposes works blind.",

That is not a laboratory claim — it is an operating hyperscale facility in this country that declines to draw cooling water at all. Which transforms the consenting conversation: when an applicant proposes a 220-million-litre groundwater take [S-14], the council's first question can now be 'why not the cooling technology your competitor operates an hour up the motorway?' My proposal: national guidance establishes closed-loop or water-free cooling as the reference technology for new facilities above a threshold, with evaporative or groundwater draw requiring specific justification against catchment state. Not a ban — an evidential burden, placed where the information and the money already sit: on the applicant.",

'Where technically feasible' and 'requiring specific justification' are the two phrases every consultant in this country knows how to write around — feasibility studies conclude what their commissioners need, and justifications get written, accepted, and forgotten. If the burden-shift is to mean anything in a hearing room, it needs teeth I can describe to a federated farmers meeting: in catchments classified as fully or over-allocated, new industrial cooling takes are simply unavailable — not 'justified', unavailable — and the applicant builds dry or builds elsewhere [S-14][S-15]. In catchments with genuine headroom, your evidential-burden mechanism is fine. Tie the rule to catchment classification, not to the quality of the applicant's paperwork. That is my price for supporting the package, and I think Aroha's science backs it.",

Strand position: (1) per-facility water-draw disclosure standard — take, source, seasonality, published, feeding allocation accounting [S-14][G-7]; (2) national assessment guidance for councils with water-free/closed-loop as the reference technology, evidence burden on the applicant [S-15]; (3) allocation-precedence rules tied to catchment classification — in fully or over-allocated catchments, new industrial cooling takes are unavailable and facilities build dry or elsewhere [S-14]; (4) carried into the RMA-replacement instruments as a national environmental standard so it survives the reform [S-14]. And one thing I want minuted for the cross-strand record: this strand does NOT accept that national-level conditions — the kind the compute and electricity teams trade in — can substitute for catchment assessment. Grid milestones are national; water is not. If the compute coupling is settled in megawatts and milestones alone, our disagreement stands, and I would rather it stand honestly in the record than be smoothed into consensus we do not have [S-14].",
