Data centre site selection, planning, and consenting considerations in New Zealand

Key takeaways

• Data centre site selection in New Zealand should be informed by a detailed planning assessment, not only power, water and connectivity.
• With no data centre-specific national direction, regional and district plan provisions will often determine consenting risk and the appropriate pathway.
• Resource management reform and signalled rules for large data centres make early engagement and policy monitoring a practical priority.

 

Data centre site selection in New Zealand

In New Zealand, data centre site selection involves more than identifying sites with appropriate access to electricity, telecommunications infrastructure and water resources. Site selection should be informed by a detailed planning assessment to identify consenting risks at an early stage as well as the appropriate consenting pathway. Given the current absence of data centre-specific national direction, regional and district plan provisions will often be a key determinant of consenting risk. Developers, operators and investors should also factor in community interests and undertake proactive engagement at an early stage to identify and address potential concerns before consent applications are lodged.

At the same time, the ongoing reform of New Zealand's resource management system creates both uncertainty and opportunity. While well-considered data centre projects should be capable of progressing efficiently under the current framework, there may be strategic value in monitoring and participating in the development of the new planning system to help ensure that it appropriately recognises and provides for data centres.

 

Highly specific locational requirements for data centres

The highly specific locational requirements for data centres are well known. They include secure and reliable electricity supplies, water availability, telecommunications connectivity, and resilience against natural hazards.

While these may represent dominant site selection factors, in the New Zealand context, consenting processes for data centres are currently governed by a wider range of considerations under the Resource Management Act 1991 (RMA), related national direction, and regional and district plans.

 

Data centre site selection issues arising in the RMA context

The RMA is currently the principal statute for managing New Zealand's built and natural environment. It establishes a hierarchy of policy statements and plans which give substance to the sustainable management purpose of the RMA. The hierarchy of planning documents includes national policy statements, national environmental standards, regional policy statements, regional plans and district plans.

Currently, there is no national direction under the RMA that relates specifically to data centres. While national direction may be relevant depending on location, the provisions of relevant regional and district plans are of central importance, and consenting processes are likely to be less complicated when site selection for a data centre project is also informed by a comprehensive planning analysis.

While a “data centre” activity may not be expressly provided for by the relevant district plan, it may be compatible with the kinds of activities typically enabled in commercial or industrial zones. Equally, there may be other locations or zones that are less suited to a data centre, potentially with relevant planning provisions that effectively prevent establishment.

The RMA focuses on managing the effects of activities. Effects assessments for data centre projects will be informed by the relevant planning provisions, and depending on the site selected and the relevant planning provisions, there will be a range of effects that will need to be comprehensively assessed as part of a consent application. A broad range of effects may be relevant, including operational effects, natural hazard constraints, infrastructure capacity, and cultural effects, with various expert assessments required to support a comprehensive consent application.

There is also potentially a choice of consenting pathways for data centre projects, with different consenting processes provided under the RMA and the Fast-track Approvals Act 2024 (Fast-track Act). The Fast-track Act provides a regime for projects with “significant regional or national benefits”. There are potential advantages and disadvantages to the different consenting pathways, and the Fast-track Act is not suitable for all projects. Notably, at the time of writing, we are only aware of one data centre project (associated with commercial buildings) that has sought approval under the Fast-track Act.

Also, of relevance to data centre developers, operators and investors is the imminent repeal of the RMA and its replacement with two Acts. The bills for these replacement Acts were introduced to Parliament in December 2025 as the Natural Environment Bill and the Planning Bill (together, the Bills). The Select Committee's reports on the Bills were released on 20 July 2026, and there is now an expectation that the Bills will become law before the November 2026 New Zealand General Election and that the new planning system will be fully implemented by early-2031. While the transition to the new system may be reasonably complex, it is anticipated that in time planning processes will be simpler with more standardisation and greater national consistency and less opportunity for public participation in the process.

The transition to the new system should not be an impediment to well considered data centre projects progressing in the interim. The transition may, however, provide opportunities for data centre developers, operators and investors to engage in the development of new planning frameworks and potentially reduce longer-term consenting risks under the new system.

With the New Zealand general election scheduled for 7 November 2026 there is an additional layer of uncertainty around the proposed legislative reforms as some opposition parties oppose key aspects of the Bills. As in some overseas jurisdictions, at least one political party is suggesting that there should be a one-year moratorium on the establishment of new AI data centres while new rules for their regulation are put in place. The Government has also recently signalled that it is developing rules for large data centres, including expectations relating to additional electricity generation.

 

Community considerations

Community opposition to data centres is common, with opposition grounded in a range of factors such as misallocation of resources and localised environmental impacts. Site selection for data centre projects should also be informed by the potential for a project to be confronted with such opposition.

Under section 36A of the RMA, there is no requirement to consult on an application for resource consent, although a duty may arise under another enactment. However, consultation is generally best practice.

Failure to consult, including with potentially affected Māori iwi groups, may have far-reaching consequences, such as opposition to a proposal that might otherwise have been avoided, insufficient awareness of how a proposal might affect other persons, or an inadequate assessment of effects. All these potential consequences point towards the merit of early and comprehensive engagement in the context of a data centre project in New Zealand.

 

Practical implications

In New Zealand, data centre developers, operators and investors should:

• Undertake a detailed planning assessment prior to site selection to identify consenting risks at an early stage.
• Carefully consider the appropriate consenting pathway, including factoring in the potential for legal challenges.
• Undertake proactive engagement at an early stage in the site selection process before any decision is made about the most appropriate site, including with any potentially affected iwi groups.
• Monitor evolving regulatory and policy developments and trends, especially in the current environment of proposed environmental land planning legislative reform and a general election to be held in November 2026.
