Review of the building consent system (snapshot)

A quick overview of the review of the building consent system options paper.

The Ministry of Business, Innovation and Employment (MBIE) is undertaking a review of the building consent system.

The aim of the review is to modernise the building consent system to provide assurance to building owners and users that building work will be done right the first time and that buildings are healthy, safe and durable.

In order to ensure buildings are healthy, safe and durable, the building consent system should primarily seek to achieve the 4 following outcomes:

Buildings are healthy, safe and durable

  • Roles and responsibilities are clear, appropriate and understood
  • System is efficient
  • System is responsive to change and continuously improves
  • Regulatory requirements and decisions are robust, predictable, transparent and understood

MBIE released an issues paper in July 2022 alongside a policy position statement on risk, liability and insurance. We received 264 submissions from a range of stakeholders. Feedback from stakeholders confirmed that the building consent system is delivering on its purpose by ensuring buildings are healthy, safe and durable, but there are opportunities to improve the system.


Key issues impeding achievement of desirable building consent system outcomes:

  • Roles and responsibilities across the building system are not wellunderstood. Building consent authorities hold too much responsibility for providing assurance of compliance with the Building Code and there are weak incentives on other system participants to get it right first time.
  • Capacity and capability constraints within the sector and building consent authorities are affecting the performance of the consent system and building outcomes.
  • The consent process is not sufficiently agile for the way we design, procure and build. Rigidity in the building consent system is stifling innovation. The system is not sufficiently responsive to Māori needs and aspirations.
  • Differences in application requirements, processes, systems and interpretation, both between and within building consent authorities, creates confusion, frustration and uncertainty for owners, designers and builders.
  • System monitoring is too focused on detailed auditing of building consent authorities rather than monitoring the performance of system outcomes.

The purpose of this consultation is to test potential options and how they could improve the building consent system. This will inform advice to Ministers on a package of preferred options for system change and the detailed design of options the Government chooses to progress.

Some options or packages of options in this paper are identified as ‘preferred’. Preferred options have been identified where policy work is sufficiently advanced and there has been previous discussion of these options. In other areas, the issues are more complex and further consultation, policy and design work is required before preferred options can be identified.

The potential reform options also address some of the recommendations made by the Commerce Commission in its market study on competition for residential building supplies.

We welcome your feedback on the potential options explored in this options paper. Submissions are due by 5pm on 7 August 2023.
