Resource Management Act 1991 (RMA) — Live Text & Reform Status

The Facts

The Resource Management Act 1991 (RMA) is the principal statute governing land use, subdivision, environmental management and resource consents in New Zealand. It sets the framework within which regional and district plans (including the Auckland Unitary Plan) are made and consents are granted. The live consolidated text is hosted at legislation.govt.nz. Since 2024 the RMA has been undergoing a significant reform programme — sections have been amended, replaced or repealed in stages. The Ministry for the Environment (MfE) page (linked) tracks current status and forthcoming amendments. Always confirm you're reading the current consolidated version before relying on any specific section number.

A Developer's Take

The RMA is the legislative foundation everything else in NZ planning sits on. The AUP, every plan change, every resource consent, every notification process: all of it operates under the RMA. If you do development work in NZ, you're working under this Act whether you've read it or not.

The trap: people refer to "the RMA" as if it's a single static document. It isn't. The Resource Management Act 1991 has been amended dozens of times. As of mid-2026 the legislation is in active reform, not static. The April 2026 amendment that reduced Auckland's PC120 capacity requirements is one example. Fast-track Approvals Act is a parallel piece of legislation that lets certain projects bypass the standard RMA process. The previous government's three replacement acts (Natural and Built Environment, Spatial Planning, Climate Adaptation) were repealed in 2024. Current direction is amend rather than replace.

What this means for developers:

1. Always read the LIVE CONSOLIDATED version of the RMA on legislation.govt.nz, not the original 1991 text or any earlier amendment.

2. Track the amendment tab on the same page. When a new amendment is enacted, planners and councils are working with the new text within weeks. You don't want to be the one citing repealed sections at a hearing.

3. Know which NPS and NES apply to your project. National Policy Statements (urban development, freshwater, indigenous biodiversity, productive land) sit underneath the RMA but have similar effect. NPS-UD is the one that drove PC78 and PC120.

4. The Fast-track Approvals Act is worth understanding even if your project is too small to use it. The eligibility criteria and the projects accepted under fast-track tell you what the government considers strategically important.

For day-to-day work you don't need to be reading the RMA cover to cover. You need to know where it lives, what's changed recently, and which sections your planner is relying on. Treat legislation.govt.nz as the source of truth, not the council's plan summary.

Ok let's be real here — this body of knowledge is huge and it's a large task to understand. Really only a broad understanding is required to push forward with confidence — this is why we employ such smart consultants. The larger the development, the more important an understanding of this is. If you're building smaller single-lot developments, your architect can handle most of this. If you're master planning a large greenfield site with a multi-year lead time, then understanding what is being put through the fast-track approval process will be of benefit to you.

When to use this

Read the RMA when you need to verify a planning consultant's opinion, when a council is interpreting a rule in a way that surprises you, or when you're drafting a submission. The live legislation site is the source of truth. For day-to-day work the MfE summary pages are more digestible. With reform underway, never quote a section number without checking the current consolidated text.
