Builders must be registered as Licensed Building Practitioners (LBP) to carry out or supervise restricted building work.
Restricted building work includes:
- anything that influences the primary structure of the property (including walls, framing, foundations, floors and roofs)
- weathertightness (anything outside of the building which prevents moisture entering your home)
- fire safety system design (for attached houses or small apartment buildings).

For work that is not restricted, you can employ builders without a licence as long as you get any necessary consents and meet the Building Code requirements.
LBP licence classes include:
- brick and blocklaying
- external plasterering
Each Licensed Building Practitioner is restricted to working within the work covered by their licence class, and they may be licenced in more than one class. Their LBP licence card will state what type of building work they may do.
Registered architects, plumbers and chartered professional engineers are allowed do or supervise some restricted building work.
