Auckland's 2025 Unitary Plan Allows Six-Story Apartments Near Transport
Changes to the Auckland Unitary Plan introduce tighter flood-risk consenting, allow six-storey apartments along transport corridors, and expand three-home developments without resource consent under the Medium Density Residential Standards.
How we reported this
The latest amendments to the Auckland Unitary Plan, which came into effect in late 2025, represent the most significant overhaul of the city’s zoning and development rules since the plan became operative in 2016. The changes affect every property owner and prospective home builder in the region, introducing stricter consenting requirements in flood-prone areas while enabling greater density along major transport routes.
The Auckland Unitary Plan governs what can be built on every piece of land in the region, replacing seven legacy district plans. The 2025 amendments focus new housing capacity near transport stops and city centres, and allow up to six-storey apartment buildings along transport corridors. For homeowners, the central government’s Medium Density Residential Standards already mean many residential properties can now accommodate up to three homes of up to three storeys-with an 11-metre height limit-without needing resource consent.
What the new zones mean for property owners
The plan maintains four main residential zones: Single House (permitting one to two storeys), Mixed Housing Suburban (one to two storeys), Mixed Housing Urban (up to three storeys), and Terrace Housing and Apartment Buildings (six storeys or more). A property’s zone determines not only the maximum height and number of dwellings but also the type of resource consent required for any development. For example, a property zoned Mixed Housing Urban can host three storeys without the same level of council scrutiny as a Single House zone.
Residents can check their property’s specific zone and rules using the Auckland Unitary Plan GeoMaps or GIS Viewer, which also display overlays and designations that may affect building permissions. Council officials recommend property owners consult these tools before any development planning, as the maps show flood-risk areas, heritage overlays, and other constraints that trigger additional consent requirements.
Practical impacts for Aucklanders planning to build or buy
For Aucklanders looking to add a granny flat, build a new home, or subdivide an existing section, the 2025 amendments mean more upfront work. Properties in flood-risk areas now face tougher consenting rules, which may require detailed hydrological reports and higher earthworks standards. Those along transport corridors-such as in suburbs near train stations or busway stops-gain the ability to build up to six storeys, opening opportunities for medium-density apartment developments without the need for a plan change.
The changes reflect a deliberate policy shift to concentrate growth in areas with existing infrastructure. The council has said the amendments are designed to reduce pressure on greenfield land and make better use of urban capacity. No specific cost estimates or projected savings have been published for the new framework, but the council expects the rules to simplify the consenting process for compliant projects.
No timeline has been confirmed for the next review of the Unitary Plan. The council has indicated it will monitor the impact of the 2025 amendments on housing supply and flood resilience before proposing further changes. For now, property owners and developers are advised to check the GeoMaps tool to understand what their zone allows and whether any overlay designations apply.
