Building and Construction Minister Chris Penk said the proposal was for building professionals with indemnity insurance working on low-risk projects.
It would allow qualified trade professionals – including plumbers, drainlayers and builders – to sign-off on their work without needing council inspection.
The changes were also expected to cover large homebuilding businesses that construct hundreds of near-identical homes a year.
“The building consent system is intended to protect homeowners from defective building work by requiring work to be inspected and consented by a Building Consent Authority,” Penk said.
“But the regime is inefficient and adds cost and time to the build process, which makes it harder for Kiwis to realise their dream of homeownership. It takes on average 569 days for a home be built and consented [to] – amid a housing shortage, that is simply too long to wait.”
Under current legislation, building consents are issued by a building consent authority, usually a local and district council, but can also be a regional council or private organisation.
Penk said the new opt-in self-certification scheme would undergo a robust consultation process in two stages.
“The first is that qualified building professionals, such as plumbers, drainlayers and builders, will be able to self-certify their own work, for low-risk builds, without the need for an inspection.
“This brings them in line with electricians and gasfitters who can already do this and is something the industry has been calling for, for years.
“The second pillar is that businesses with a proven track-record – for example, group homebuilders who build hundreds of near identical homes a year – will be able to go through a more streamlined consent process.
“At the moment, a single-story basic home might go through 10 or more separate inspections. This is clearly too many and the cost-benefit has become unbalanced.”
Penk said building professionals are already subject to quality assurances, including holding a practising licence, keeping records of their work and having their details in a publicly searchable database.
Additional safeguards like a clear pathway for customers to remedy poor work, tougher qualification requirements for building professionals and strict disciplinary actions for careless or incompetent self-certifiers would be put in place, he said.
“We will make detailed policy decisions in the new year following thorough consultation, which will consider what residual role existing Building Consent Authorities should have in the self-certification scheme, for example through an auditing function.
“Kiwis need confidence in the safety and quality of their homes, but it’s possible to do this through a more streamlined assurance pathway. We are committed to cutting through the tangle of red tape so that we can get more Kiwis into the quality homes they deserve.”
