## Summary

Datagrid's Makarewa AI data centre in Southland, [New Zealand](/en/entity/new-zealand), holds resource consents to draw 600,000 litres of groundwater per day, according to NZ Newswire; the company says it will use rainwater in practice. A water-consent expert cited by Otago Daily Times warned [New Zealand](/en/entity/new-zealand)'s resource management scheme is "not fit to manage the long term impact of hyperscale" facilities. Farmers Weekly reported an engineer is questioning whether the regulatory framework is equipped for AI data centres' demands at all. Southland groundwater is also drawn on by agricultural users in the region.

## The split

Regional and agricultural New Zealand media both frame this as a regulatory gap story, but with different emphases. ODT and RNZ lead with the systemic failure angle: the existing consent regime was designed for other industries and cannot account for the scale or permanence of AI data centre water draws. Farmers Weekly adds the competition angle: farming and AI facilities share Southland aquifer resources, and the consent volume sets a precedent for future approvals. Datagrid says it will not use groundwater in practice, but the consent remains on the books.

## By the numbers

- 600,000 litres of groundwater, the daily draw Datagrid is consented to take
- 1 data centre (Makarewa) named in the current regulatory concern
- 0 litres, what Datagrid says it will actually draw, preferring rainwater

## Why it matters

AI data centres are among the most water-intensive facilities being built at scale globally. New Zealand's Southland region is attracting AI infrastructure investment, and the consent regime was written before hyperscale facilities existed. Without regulatory reform, [New Zealand](/en/entity/new-zealand) risks granting groundwater rights for AI campuses that permanently change local water tables, affecting farming and local communities.

## What to watch

- Whether Southland's regional council reviews or tightens groundwater consent conditions for data centres
- New Zealand government response to the regulatory-gap warning
- Further AI data centre consent applications in Southland or other New Zealand regions

## Regional takes (batched by bias / lens)

### Regional daily covering Southland and Otago; leads with the warning from a water-consent expert that New Zealand's resource management scheme is "not fit" for managing hyperscale data centre impacts long-term, foregrounding local infrastructure stress
- **Otago Daily Times** (New Zealand, en) — The Otago Daily Times, carrying RNZ reporting, quotes a leading water-consent expert warning that New Zealand's resource management framework cannot handle the long-term groundwater demands of hyperscale AI data centres; the article frames the Makarewa consent as a specific example of a systemic regulatory gap affecting the Southland region.

### New Zealand agricultural media; covers the groundwater consent through the lens of rural and farming water interests, noting an engineer's concern that AI data centres and agricultural water users will compete for the same Southland aquifer resources
- **Farmers Weekly NZ** (New Zealand, en) — Farmers Weekly quotes an engineer questioning whether New Zealand's resource management framework is equipped for the water demands of AI data centres; the agricultural angle highlights that Southland groundwater is shared with farming and that the 600,000-litre daily consent volume sets a precedent for future AI facility approvals in the region.
