RMA changes and what they mean for Selwyn landowners

Across Selwyn, plans for a new home, a subdivision or a farm business expansion often begin with a practical question: what approvals do we need? Changes to the Resource Management Act (RMA) make this a good time to revisit that question.

The Planning Act and Natural Environment Act received Royal assent on 30/09/2026, beginning the transition to a new planning system. Existing plans and the RMA continue to apply during that transition, with targeted consenting changes starting on 30/10/2026. Consenting under the full new system is currently expected in 2030.

For district land-use consent applications lodged from 30/10/2026, councils must disregard specified matters. For residential activities, these include internal layouts, unit size, glazing, balconies and outdoor living space. The size of landscaped areas is also excluded, except where it relates to how water soaks into the ground. The residential exclusions do not override historic heritage protection.

Councils must also disregard private views, effects on trade competition and retail distribution, a project’s lack of demand or financial viability, and the type of residents a development will house.

For Selwyn, this could give some housing and business proposals greater flexibility. It could also reduce the information needed to address matters that are no longer relevant to the decision. The effect on individual Selwyn District Plan rules is still being worked through, so early advice will be useful.

These changes do not automatically make a project permitted. Flooding, traffic safety, wastewater and other relevant effects can still need assessment. Irrigation and discharge proposals also need their regional consent requirements checked.

The process should become more practical, too. New principles require decision- makers to take practicable steps to keep documents concise and understandable, obtain necessary information with regard to its cost and the scale of the issue, and support practical solutions. For once, the paperwork is telling us to produce less paperwork.

Timing matters. Applications lodged before 30/10/2026 continue under the earlier assessment framework. Accessing the new provisions requires a new application.

Before withdrawing and relodging an existing proposal, weigh any likely benefit against additional fees, delay and work already completed.
Selwyn’s rural community has practical knowledge to contribute. If a worthwhile idea has been sitting in the bottom drawer, now is a good time to dust it off, check the pathway and help shape the plans that will affect its future.
