Development contributions are council charges for new demand on infrastructure. Why they can make or break a development feasibility.
Development contributions are charges levied by a council on new development to fund the additional demand it places on infrastructure — water, wastewater, stormwater, transport and community facilities.
Typically on subdivision, on adding new dwellings including minor dwellings, and on developments that increase demand on services. They are usually assessed at resource consent or building consent stage and payable before titles issue or before a code compliance certificate is granted.
They can run to tens of thousands of dollars per additional lot or dwelling, and they vary enormously between councils and between locations within a council area. Some councils also levy separate financial contributions under their district plan.
They are one of the most commonly underestimated line items in a development feasibility, and they are large enough to turn a marginally profitable project into a loss.
Get an estimate before you buy, not after consent. Most councils publish their development contributions policy and many provide an estimation tool or will give an indicative figure on request.
Contributions policies are reviewed periodically, and the applicable rate is generally the one in force when the contribution is assessed — so a long project can be caught by an increase.
They are not a fee for the consent itself. Consent processing fees are separate and additional.
Adding a granny flat can trigger them, even where the build itself no longer requires building consent under the 2026 exemption. Consent exemption is not contribution exemption — check with your council.
