A series of planning and building regulatory changes took effect in January 2026 that have direct implications for housing development, resource consenting and smaller dwelling builds in New Zealand. The two most policy-relevant developments are the introduction of a granny flat consent exemption and the implementation of updated National Direction instruments under the country’s planning framework.
Granny Flat Consent Exemption Takes Effect
As of 15 January 2026, the Government officially enacted updated provisions to the Building Act 2004 and associated National Direction that remove the requirement for both building and resource consent for certain small standalone residential units (commonly known as “granny flats”) up to 70 square metres in size.
Housing and RMA Reform Minister Chris Bishop highlighted that the change is designed to reduce cost and complexity for homeowners and investors seeking to build simple second dwellings. Exemptions can save up to NZ$5,650 in direct costs and potentially shorten build time by up to 14 weeks compared with full consent pathways.
Despite the exemption, builders and property owners must still:
- Comply with the Building Code and design standards.
- Notify the local council and obtain a Project Information Memorandum (PIM) before work begins.
- Ensure all work is carried out or supervised by licensed building professionals.
Local authorities can still apply development contributions and other infrastructure connection conditions, meaning the exemption does not eliminate all costs or compliance obligations for developers.
National Direction Changes Now in Force
In conjunction with the granny flat exemption, the Government implemented a set of National Direction instruments as of 15 January 2026. These instruments include amendments to existing policy statements and new direction intended to support housing, infrastructure and environmental outcomes across the planning system.
The updated National Direction framework is part of the ongoing resource management reform, designed to create clearer policy settings and consistent planning signals nationwide. These changes influence how councils assess and manage development impacts, particularly in areas such as housing capacity, transport, infrastructure delivery and environmental protection.
What This Means for Developers and Investors
- Reduced Administrative Barriers: Small dwelling projects now have fewer regulatory hurdles, potentially lowering initial build costs and reduce timeline uncertainty.
- Continued Compliance Requirements: Although exemptions apply, compliance with the Building Code, infrastructure contributions and local building conditions remains crucial — especially in urban growth areas like Hamilton and Waikato.
- Policy Certainty: Implementation of new National Direction instruments provides more defined planning expectations for councils and developers, supporting better long-term project planning.
These shifts represent significant regulatory updates in early 2026, aligning with the Government’s housing and planning reform agenda and offering practical opportunities for more agile housing delivery.
