New Zealand's Southland AI data centre holds consent to draw 600,000 litres of groundwater daily, raising resource-management questions

Datagrid's Makarewa AI data centre in Southland holds consents to draw 600,000 litres of groundwater a day, though the company says it will use rainwater; engineers and water-consent experts warn New Zealand's resource-management framework is not equipped for the water demands of hyperscale AI facilities

Summary

Datagrid's Makarewa AI data centre in Southland, 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'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 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
