Auckland Unitary Plan — Developer's Guide to Zoning & Rules

The Facts

The Auckland Unitary Plan (AUP) is the integrated planning document that governs land use across the Auckland region. It replaced seven legacy district plans when it became operative in 2016 and now defines what can be built on every property in Auckland. The AUP works through a hierarchy of zones (Single House, Mixed Housing Suburban, Mixed Housing Urban, Terrace Housing and Apartment Buildings, plus business, rural, and special purpose zones) and sets rules for height-to-boundary, site coverage, density, parking, outlook, and many other development controls. The AUP Viewer is an interactive GIS map that lets you click any Auckland address to see its zoning, overlays, designations, and the specific rules that apply.

A Developer's Take

Every Auckland deal starts here. The AUP Viewer is free, takes five minutes, and tells you what you can and can't do with your property in broad brush strokes.

The mistake most first-time developers make is treating the AUP Viewer as the final word. It isn't. Operative-in-part 2016 means there are plan changes layered on top that materially change what you can build. PC78 changed Centre Zone rules in May 2026. PC120 (Housing Intensification & Resilience) is being renegotiated right now after the government changed the RMA on 30 April 2026 to reduce required capacity. If you only check the AUP Viewer, you are working from incomplete information.

My suggested workflow:

1. Open the AUP Viewer, click the address, read the underlying zone.
2. Open the relevant plan change viewer for that zone (PC78 for Centres, PC120 for residential intensification). Plan changes layer on top of the AUP zone rules — read them together, not separately.
3. Check the Plan Change Register for anything notified in the last six months. New plan changes you do not yet know about can flip a feasibility.
4. Work through the overlays one by one — designations, heritage, archaeology, flood, viewshafts. Any single one of these can disqualify a yield assumption.
5. Synthesise what the AUP, the active plan changes, and the overlays collectively tell you about permitted activity, height, density, and site coverage before you spend a cent on concept design.

Five minutes here saves weeks chasing the wrong site. The AUP also tells you what controls (height-to-boundary, density, site coverage, outlook) will actually drive your design, before you spend a cent on a concept plan.

If you are uncertain about what any of this means, there is typically a link on the LHS at the bottom of the Viewer page called "View Unitary Plan Text". You can then search your designation or control there and try to further understand what you are dealing with. Chapter H is the zones chapter — arguably the most helpful chapter of them all.

When to use this

Every Auckland development project starts with the AUP. Open the Viewer the day you start considering a site — before you have title, before a LIM, before back-of-envelope feasibility. Click the address, read the zone, then check overlays (flood, designation, heritage, archaeology) one by one. Five minutes here tells you whether the yield you assumed is real or fantasy, and which controls (height-to-boundary, density, site coverage) will drive your design. Use it again at concept design to confirm permitted-activity status before paying a planner.
