The Resource Management Act 1991

What the Act does

The Resource Management Act 1991 (RMA) governs how New Zealand's natural and physical resources — land, air, water, the coast — may be used.
Its purpose is sustainable management: allowing people to use resources while safeguarding their capacity to meet the needs of future generations, avoiding or mitigating adverse effects on the environment.
It is administered mostly by local government: regional councils (water, air, discharges, coastal) and district or city councils (land use, subdivision, noise).

Reform in progress. Replacement legislation — a Natural Environment Bill and a Planning Bill — was released for consultation in December 2025 and is before Parliament. Until it is enacted, the RMA 1991 is the operative Act, and it is the Act named by the Business Studies teaching guide and used in the exam. Refer to the Resource Management Act 1991 in your answers, and note the reform only if the question invites it.

What it means for a business

Resource consents.

Activities that affect the environment need a resource consent from a council unless a plan permits them outright.
Common consents for businesses: taking water for irrigation or processing; discharging to water, land or air; building or expanding premises; making noise beyond a permitted level; earthworks; coastal activities.
Consents carry conditions — limits on volumes, monitoring and reporting requirements, hours of operation — and the business must comply with every one.

The process.

The business applies to the council, which decides whether the application is notified (open to public submissions) or non-notified.
Notified applications can attract submissions from neighbours, iwi and hapū, and community groups, and may go to a hearing. This is the point at which a business's community relationships become measurable in time and money.
Decisions can be appealed to the Environment Court, which adds cost and delay.

Enforcement.

Councils can issue abatement notices requiring an activity to stop, and infringement notices with fines.
Serious breaches can lead to enforcement orders and prosecution, with substantial penalties.
The commercial risk is rarely the fine: it is the stop-work order, and the reputational damage of a public breach.

The impacts on a business

Costs and constraints	Benefits
Consent applications cost money and take months, delaying projects	A granted consent gives legal certainty to operate and to invest
Conditions limit what the business may do, and require monitoring	The same rules apply to competitors, so no one gains by polluting
Compliance investment — treatment plants, bunding, noise control	Meeting standards early avoids forced retrofit later
Objections can delay or defeat an expansion	Environmental performance supports the business's brand and export claims

How businesses respond

Plan early and build consent timeframes into the project schedule, so a consent is not the thing that delays a build.
Engage before applying — with neighbours, and with iwi and hapū where land, water or sites of significance are affected. Consultation before an application is far cheaper than opposition after it.
Design out the effect — reduce the discharge, recycle the process water, relocate the noisy activity — so a lesser consent is needed, or none.
Monitor and report accurately, because most enforcement follows a failure to monitor rather than a deliberate breach.
Invest ahead of the standard where regulation is clearly tightening, so the upgrade happens at a time of the business's choosing.
The Act is also the clearest legal expression of kaitiakitanga: the resource must remain able to meet the needs of future generations, which is guardianship written into law.
