Auckland accounts for around a third of New Zealand’s population and a larger share of its construction activity. It also has a planning and infrastructure environment that differs enough from the rest of the country that experience elsewhere transfers imperfectly.
The Unitary Plan
The Auckland Unitary Plan is the combined regional and district plan governing what can be built where. It replaced a set of legacy plans inherited from the councils amalgamated in 2010, and it introduced substantially greater enabled density across much of the urban area.
The zone determines the fundamentals — height, site coverage, setbacks, outlook, permitted density — and the difference between adjacent zones can be the difference between a viable development and an unviable one. Zone boundaries are the first thing to check on any site, before anything else.
Overlays sit on top of zones and frequently control the outcome: special character areas, heritage, volcanic viewshafts, natural hazards, and the coastal environment all restrict what the underlying zone would otherwise permit. A site in a permissive zone with a special character overlay may be considerably more constrained than the zone suggests.
Density enablement and its limits
National direction on housing intensification interacts with the Unitary Plan, and the settings have been subject to repeated change at central government level. The direction of travel has been toward greater enabled density near centres and transport, with debate about how far that should extend into established suburbs.
Because this area has moved and continues to move, anyone planning a development on the basis of enabled density should confirm the current operative position rather than relying on advice from even a year or two ago.
Infrastructure is the real constraint
Planning permission to build is not capacity to connect. Auckland’s binding constraints on development are frequently infrastructural rather than regulatory:
- Wastewater capacity, which limits development in parts of the network and can require upgrades funded by the developer.
- Stormwater management and hydraulic neutrality requirements, which affect site layout and cost.
- Water supply capacity in growth areas.
- Transport network capacity and the trip generation assessment for larger developments.
- Electricity network capacity, which is an increasing constraint as electrification proceeds.
Development contributions are payable toward infrastructure, and they are a material line item that should be established early rather than discovered at consent.
The consenting environment
Auckland Council processes a very large volume of consents, and the practical experience turns on the same factors as anywhere: whether the application is complete, whether it is notified, and how many information requests it generates.
For development of any scale, obtaining written approvals from affected parties before lodging is frequently the difference between a non-notified consent processed in weeks and a notified process running for a year with appeal risk.
Both land use consent from the council and, where relevant, regional consents for earthworks, stormwater discharge or vegetation removal may be required, sometimes on different timelines.
Site-specific issues that catch developers
- Ground conditions. Auckland’s geology varies dramatically over short distances, and foundation cost differences between adjacent sites can be substantial. Geotechnical investigation before purchase, not after.
- Contamination. Former industrial and horticultural land carries requirements under the national environmental standard for contaminated soil, and remediation can be a project-defining cost.
- Natural hazards. Flooding and land instability overlays have received significantly more attention following recent severe weather events, and they affect both consentability and insurability.
- Existing use rights and legacy consents on sites with a development history.
Practical sequence
Check zone and overlays, then infrastructure capacity, then ground conditions and contamination, then development contributions — before committing to a site. Each of these has killed projects that were viable on the planning provisions alone.
