Datagrid AI Factory: Makarewa, Southland
Datagrid · Southland
A 78,000 square metre hyperscale AI data centre campus on 49 hectares at Makarewa, north of Invercargill, consented in March 2026 as a $3.5b investment. At about 280MW it would be the country's second-largest electricity user after Tiwai Point, fed by a dedicated Transpower grid exit point and a 140MW Mercury deal. Full buildout runs into the 2030s.
Data current as at 16 Sept 2026, when the pipeline was last checked against its source.

Election risk assessment
Privately funded and largely election-independent, but faces power-supply, grid-connection and subsea-cable hurdles. Its 280MW demand (NZ's 2nd-largest user after Tiwai) draws scrutiny.
Government priority alignment
MEDIUM: Major digital + energy infrastructure and FDI; very large electricity demand.
