New Zealand's government is chasing up to NZ$35bn of private investment to build an AI data centre industry. The country has about 154MW of capacity built and one project at the scale the pitch implies.
In late June, Invest New Zealand gathered around 100 senior business leaders in Auckland and put a number to the ambition: NZ$25bn to NZ$35bn of private investment across data centres, renewables, fibre and transmission over five years. Chief executive Robert Wall called it a call to arms. Contact Energy's Mike Fuge called it a "once-in-three-generations opportunity," alongside refrigerated meat shipping in the 1870s and the wool boom of the 1950s, in The Spinoff's account of the meeting.
The pitch rests on a Boston Consulting Group report from February 2026 arguing New Zealand could unlock up to $70bn of economic activity over a decade from 600MW of new build. The country has 154MW of colocation capacity built today. The NZ$25bn to NZ$35bn figure appears in no published Invest New Zealand document we could locate. It stands as a stated ambition, and the whole ambition rests heavily on one project in Southland.
Datagrid's 280MW campus clears consent with three gaps open
Rémi Galasso built the Hawaiki trans-Pacific cable before he built Datagrid. His campus at Makarewa, a quarter of an hour north of Invercargill, won full resource consent on 11 March 2026 from Southland District Council, Environment Southland and Invercargill City Council. At full build the 280MW campus would draw about 6% of New Zealand's electricity. Rio Tinto's Tiwai Point smelter, on 572MW, is the country's largest single user.
Three things are outstanding. On money, Galasso messaged the NZ Herald in late June: "Still working on it." On power, Mercury has signed a fifteen-year option over 140MW, short of a firm supply contract, which chief executive Stewart Hamilton said preserves flexibility before a final investment decision. On the cable, Chorus signed on in December 2024 and withdrew in August 2025, chief executive Mark Aue saying "pre-sales commitment was not stacking up" and a realistic in-service date was now past 2030. Datagrid targets opening in 2028.
The consent covers a 78,000 square metre campus of six data halls, backed by 84 emergency generators. Datagrid's application projects up to 5,400 construction jobs, 72 full-time roles once operating, and NZ$36m a year to GDP.
Southland's export bet hinges on a cable the island lacks
New Zealand is too small to consume 280MW of compute itself, so the Southland campus only works if it sells that capacity offshore. Selling compute means connecting it, and the South Island has no direct international cable. Every existing link, Southern Cross, Southern Cross NEXT, Hawaiki and Tasman Global Access, lands in the North Island around Auckland.
A June 2025 MBIE briefing to the Minister for the South Island called the cable "essential for the data centre." The Tasman Ring Network, announced with Chorus in December 2024, would be a 6,000km loop connecting Bluff to Sydney and Melbourne and giving the South Island its first direct international connection. Datagrid has taken the project in-house since Chorus left, which puts a 6,000km subsea system back in the hands of the man who built Hawaiki. Southern Cross's contracted SX Tasman Express, by contrast, lands in Auckland, so it strengthens the North Island cloud market and leaves a Southland export campus no better connected.
Foreign capital owns most of New Zealand's data centre operators
Most of New Zealand's data centre operators are foreign-owned. Brookfield holds DCI, Pacific Equity Partners holds 75% of TenPeaks, and NEXTDC, Microsoft and AWS are Australian and American. Infratil-led CDC and Datacom are the significant domestic positions. Microsoft, AWS and Datacom disclose no megawatts, so nobody can weight this by capacity. Even the disclosed figures are contested: Infratil puts CDC's three Auckland campuses at about 80MW operating, while the NZ Herald reports close to 220MW.
| Operator | Owner | Status |
|---|---|---|
| CDC | Infratil (NZ) 49.75%, Australian Government Future Fund 34.55%, Commonwealth Superannuation Corporation 12.04% | Operating across three Auckland sites; 90MW future build |
| DCI Data Centers | Brookfield (Canada) | AKL01 Westgate operating; AKL02 Albany first stage complete, designed for 40MW |
| TenPeaks | Pacific Equity Partners (Australia) 75%, Spark 25% | Operating; 11 facilities, 130MW+ pipeline |
| Datacom | Datacom (NZ) | Operating; five facilities after buying T4's Auckland site in March 2026 |
| NEXTDC | ASX: NXT (Australia) | AK1 under construction, 10MW scaling to 15MW |
| Microsoft | Microsoft (US) | New Zealand North operating since December 2024 |
| AWS | Amazon (US) | Asia Pacific (New Zealand) operating since September 2025 |
| Datagrid | Formerly Galasso family trust 62.5%, BW Digital 37.5%; a November 2025 OIO update records BW's stake sold to a Galasso entity | 280MW consented March 2026, 1GW ambition |

The hyperscalers arrived and then slowed their own building. AWS opened its Auckland region in September 2025, then wrote off NZ$44.9m on a Westgate development it abandoned after earthworks. Microsoft let a time-limited Overseas Investment Office consent lapse on a second Auckland site at Whenuapai. Both now favour leasing colocation, and the NZ Herald reports Google has done a colocation deal with an unnamed provider. Growth is running through the operators above.
Only one of three power deals is firm supply
The energy agreements behind New Zealand's biggest builds use different instruments, and the instrument decides which projects can be financed.
| Deal | Instrument | What it actually is |
|---|---|---|
| Mercury and AWS, Turitea South | Firm corporate power purchase agreement | Physical electricity, 15 years, roughly half a 103MW wind farm's output |
| Contact and Microsoft, Te Huka 3 | Renewable Attribute Purchase Agreement | Renewable certificates over 51.4MW of geothermal, without physical supply |
| Mercury and Datagrid, Makarewa | Power Purchase Option Agreement | An option over 140MW, half the campus |
Source: company releases, July 2026.
Only one of the three is a firm power contract, and it covers output from a wind farm already built. As at March 2026 Meridian, Contact and Genesis had no commercial agreement with Datagrid. Mercury chief executive Stewart Hamilton described the position to the NZ Herald as "a component of chicken-and-the-egg."
The grid can't switch off an AI training load in a dry year
New Zealand generated 85.5% of its electricity from renewables in 2024, per MBIE, and the figure moves with rainfall because the backbone is hydro. In a dry year the country has historically closed the gap by paying its largest industrial user to reduce demand. Tiwai Point holds 185MW of contracted demand response. Transpower's Winter 2025 review records storage coming within 560GWh of the point at which it judges a 1% risk of running dry. The Taranaki gas plant closed at the end of 2025.
A 280MW AI training campus offers nothing equivalent, because a GPU cluster mid-training run cannot be switched off the way a smelter can. That question sits under the entire NZ$35bn pitch, and it is the same firming problem Australia is working through, which our sister publication set out in its analysis of data centres, renewables and power bills. Transpower's new connection enquiries dashboard, updated 4 July 2026, records 30 data centre enquiries, sixteen of them in Auckland and four across Otago and Southland, nearly double the sixteen it recorded in 2023. BCG estimates that a further 1.8 to 4.0TWh of demand by 2030 would open a 1.4 to 3.6TWh shortfall against the renewable generation pipeline.
Faster screening and a tax break favour offshore builders
Two changes matter to anyone underwriting a build here. The Overseas Investment (National Interest Test and Other Matters) Amendment Act came into force on 6 March 2026, replacing the benefit-to-New Zealand test with a single national interest test and a fifteen working day screening timeframe. The Investment Boost measure, effective from 22 May 2025, allows an immediate 20% deduction of a new depreciable asset's cost, uncapped, covering commercial buildings, fit-out and equipment. Neither is data centre specific. Both favour capital-intensive builds funded from offshore, which describes every project in this article.
Datagrid consents 220 million litres of water a year
Environment Southland's water permit for Datagrid, issued 11 March 2026, allows an evaporative cooling take of seven litres a second, 604,800 litres a day and 220,752,000 litres a year. For scale, a 1,000-cow Southland farm sought 120,000 litres a day in 2022.
Public sentiment is not where the pitch places it. The Ipsos AI Monitor 2025 found 66% of New Zealanders say AI makes them nervous, second among 31 countries behind Australia at 67%. A change.org petition opposing the Invercargill campus closed with 26,027 signatures. Against that, Southland Mayor Rob Scott and Invercargill Mayor Tom Campbell have both backed the project, and Datagrid will invite Kā Papatipu Rūnaka, the region's Ngāi Tahu groups, to form a joint working group called Te Rewa to set customary practice for the build. The Southland District Council decision records that the project "aligns with iwi aspirations for sustainable land use and environmental restoration."
Financial close is the gap between consent and a project
A 280MW campus holding a 140MW price option and no announced debt is a consent. Financial close would make it a project.
| Catalyst | What it determines |
|---|---|
| Datagrid financial close | No debt announced, and no other consented project at this scale |
| Transpower Works Agreement | Two years indicative once signed; Datagrid funds a 220kV substation |
| Tasman Ring in-service date | MBIE calls the cable essential and expected 2027; Chorus said past 2030 |
| Conversion of the Mercury option | An option becomes firm supply, or it lapses |
| Invest New Zealand publishing its target | NZ$25bn to NZ$35bn has no published document behind it |

New Zealand has the renewable power and the government backing. Whether the connectivity and the capital arrive to match them is the question the next twelve months answer.
