What's the difference between resource consent and building consent in NZ?
Short answer
Resource consent comes from the Resource Management Act — it's about land use, district plan rules, and how the build affects neighbours and the environment. Building consent comes from the Building Act — it's about whether the construction meets the Building Code (structure, weathertightness, safety). Most builds need both. They're issued by the same council but assessed separately.

- Resource consent — RMA 1991, district plan, neighbour effects
- Building consent — Building Act 2004, Building Code compliance
- Both can be needed for one project
- Resource consent first (set the rules), then building consent (build to the rules)
- RC processing time: 20 working days statutory, often longer in practice
- Some councils run them in parallel via combined application
Resource consent — when it's triggered
Site coverage exceeds the district plan limit. Height exceeds the zone rule. Setbacks from boundary aren't met. Trees are protected (notable trees / heritage). Earthworks above a volume threshold. Land use conflicts (e.g., commercial work in residential zone). Notified applications can take 6+ months.
Most standard houses on standard suburban sections only need building consent. The resource consent path kicks in for unusual builds, infill sites, sloping sections, or where rules have tightened recently.
Building consent — when it's triggered
Any building work over the Schedule 1 exemptions. New houses, additions, recladding, structural changes, plumbing/drainage changes, decks over 1.5m, sheds over 30m². The list is broad — when in doubt, ask the council.
The consent covers Building Code compliance. The plans go in with calculations, geotech, engineering, and producer statements as needed.
Knowing the rules is half the job. The other half is knowing who you're hiring. Check any NZ builder against the public record: company status, licensing and insolvency notices, from the official NZ sources.
