The Green Party wants the government to stop approving new AI data centres for one year, until proper national rules are in place. RNZ

Co-leaders Chlöe Swarbrick and Marama Davidson announced the plan after the party's annual meeting on 26 July 2026. RNZ A data centre is a large building full of computers that store information and run software, including artificial intelligence. The Greens want to pause new consents for the biggest of these for twelve months while Parliament writes new laws to regulate them. Those laws are not expected to pass until early 2027. 1News

The trigger is a company called Datagrid, based in Singapore, which got permission in March to build a $3.5 billion data centre in Southland. RNZ The Greens say that one facility alone would use about six percent of all the electricity produced in New Zealand. Green Party

The party also says communities have been pushing back against these big data centre proposals, which is another reason to pause. Green Party (Facebook)

Prime Minister Christopher Luxon quickly rejected the idea. RNZ He said data centres are important for growing the economy. RNZ

The broader context is that this is a new political fight over an issue that has mostly been dealt with by local councils, not central government. A single facility using six percent of the country's power is a lot. The Greens are arguing New Zealand should sort out its rules before big projects are locked in. The government sees data centre investment as something to encourage, not hold back.

The two sides are far apart. The Greens' pause would cover the exact period when the new laws are still being written, so the idea is to stop consents being granted under the old rules before the new ones arrive. Luxon's rejection means the government thinks the risk of scaring off investment matters more than the risk of approving projects that might later break rules that do not exist yet.

For the data centre industry, the message from government is that consents will keep being processed as usual. For people who oppose specific projects, the Greens have now given them a voice in Parliament, not just in council hearings. Whether other parties will back a pause is a question the Greens have not yet answered.

The Datagrid project in Southland will be the one to watch. It was approved under the current rules. If the new laws expected in 2027 are stricter, it is not clear whether existing consents like Datagrid's would be affected or only future applications. The Greens have not addressed that detail.

What is clear is that AI data centre policy has become a national political issue, not just a local planning one. The Greens have taken a position and the government has rejected it. The next move belongs to whoever writes the new laws.
