The Licensed Building Practitioners (LBP) scheme gives New Zealand homeowners a reliable way to check that the people working on their home are qualified, registered, and legally accountable. Introduced under the Building Act 2004, it means that certain critical building work can only be carried out or supervised by a licensed professional — giving you real protection when it matters most.
What Is the LBP Scheme?
The LBP scheme is administered by the Ministry of Business, Innovation and Employment (MBIE) and sets a national standard for building practitioners working on residential buildings. To become licensed, a tradesperson must demonstrate their skills, knowledge, and experience in their specific area of work. Licences must be renewed regularly, and practitioners must meet ongoing competency requirements.
You can verify whether a builder or carpenter holds a current licence by searching the public register at Licensed Building Practitioners. This takes only a few minutes and is well worth doing before you sign any contract.
What Is Restricted Building Work?
Restricted Building Work (RBW) is the cornerstone of how the scheme protects you. Under the Building Act, certain types of work that affect the structural integrity or weathertightness of a home must be carried out or directly supervised by an LBP. This includes:
- Structural carpentry — framing, foundations, and load-bearing elements
- External cladding — installing weatherboards, plaster systems, or other cladding that keeps water out
- Roofing — work that affects the weathertightness of the roof
- Design — design work for the above categories
If a non-licensed person carries out restricted building work, the homeowner may face serious consequences — including difficulties getting a Code Compliance Certificate (CCC) and potential liability issues if problems arise later.
The Record of Work: Your Paper Trail
One of the most practical protections the LBP scheme provides is the Record of Work (ROW). When an LBP completes restricted building work on your home, they are legally required to provide you and your local council with a Record of Work on completion. This document:
- Confirms who did the work and what their licence covers
- Describes the restricted building work they carried out
- Forms part of the documentation needed for your Code Compliance Certificate
This paper trail is invaluable if you ever sell your home, make an insurance claim, or need to prove the work was done properly. Always ask your LBP for their Record of Work and keep it with your property documents.
Accountability and Complaints
Because LBPs are registered professionals, they can be held accountable in ways that unlicensed tradespeople cannot. If an LBP does substandard work or behaves unprofessionally, you can make a formal complaint to MBIE Building Performance. Possible outcomes include:
- A formal warning
- Conditions placed on their licence
- Suspension or cancellation of their licence
This accountability mechanism gives you genuine recourse — something you simply don't have if you hire an unlicensed person.
How the Building Consent Process Connects
Most significant building work in NZ requires a building consent from your local council before work begins. The LBP scheme works hand-in-hand with this process. Your council will want to know that restricted building work is being carried out by a licensed practitioner, and the Record of Work is required before a CCC is issued.
For smaller projects, some work may be exempt from building consent under Schedule 1 of the Building Act — but even then, restricted building work rules still apply. Always check with your local council before assuming your project is exempt, as the rules can be nuanced and vary by situation. MBIE Building Performance has detailed guidance on what requires consent.
BRANZ is also an excellent resource for understanding NZ building standards and best practice, including guidance relevant to the Building Code.
Licence Classes to Look For
LBP licences are divided into classes. For carpentry and general residential building work, the most relevant are:
| Licence Class | What It Covers |
|---|---|
| Carpentry | Structural and general carpentry, framing |
| Site | Overall site management of restricted building work |
| Design | Designing restricted building work |
| Roofing | Weathertight roofing work |
| Cladding | External cladding systems |
Always confirm that the LBP you hire holds the correct licence class for the work you need done.
When to Call a Professional
Any time your project involves structural work, external cladding, roofing, or anything that requires a building consent, you should engage a licensed LBP. Attempting to cut costs by using an unlicensed builder for restricted building work can result in:
- Inability to obtain a Code Compliance Certificate
- Costly remediation work
- Reduced property value or difficulties selling
- Insurance complications
