The Green Party of Aotearoa New Zealand wants a one-year moratorium on resource consents for new AI data centres, calling on the government to hold off until national rules are in place. RNZ

Co-leaders Chlöe Swarbrick and Marama Davidson announced the policy after speeches at the party's AGM on 26 July 2026. RNZ The proposal would freeze new consents for hyperscale AI data centres — the largest class of facility, typically housing tens of thousands of servers — for twelve months while legislation setting up a national regulatory framework works its way through Parliament. That legislation is not expected to pass until early 2027. 1News

The immediate trigger is a Singapore-based company, Datagrid, which was granted resource consent in March to build a $3.5 billion data centre in Southland. RNZ The Greens say that one facility is expected to draw about six percent of New Zealand's total electricity supply. Green Party

Prime Minister Christopher Luxon moved quickly to reject the proposed moratorium. RNZ Luxon said data centres are vital for economic growth. RNZ

The broader context here is that this exchange draws a clearer political dividing line on an issue that has so far been more of a concern for councils and communities than for Cabinet. A hyperscale facility drawing six percent of national electricity demand is a substantial load on the grid. The Greens have framed the consenting gap as a question of whether New Zealand gets its regulatory framework in place before large-scale commitments are locked in. The government's position treats data centre investment as something to encourage rather than constrain.

The gap between those two positions is wide. The Greens' moratorium would cover exactly the period in which the legislation is still being drafted and debated, so the pause is designed to prevent consents being issued under the current rules before the new ones arrive. Luxon's rejection signals that the government weighs the risk of deterring investment against the risk of consenting projects that may later fall foul of a framework not yet enacted.

For the data centre sector, the signal from the Beehive is that consents will continue to be processed under existing arrangements. For opponents of specific projects, the Green Party's intervention provides a parliamentary platform for arguments that have so far played out in resource consent hearings. Whether that translates into broader cross-party support for a pause is a separate question, and one the Greens have not yet answered.

The Datagrid consent in Southland will be the test case. It was granted under the current framework. If the legislation expected in early 2027 introduces stricter national rules, the question of whether existing consents are affected, or whether only future applications are caught, will depend on the drafting. That is a detail the Greens' announcement does not address.

What is clear is that AI data centre policy has moved from a planning and infrastructure issue into the political mainstream. The Greens have staked out a position; the government has rejected it. The next move belongs to whoever drafts the legislation.
