3. When was the LBP scheme introduced and from what date do builders have to be licenced?  

·         From April 2010, people registered to carry out building work under other statutory registration systems, are automatically treated as licensed under the corresponding class in the LBP scheme for the purpose of carrying out restricted building work.

·         you will need to be licensed if you wish to carry out or supervise restricted building work from 1 March 2012.

4. The is the difference between the building act, building regulation and the building code?

·         In New Zealand, the building of houses and other buildings is controlled by the Building Act 2004. It applies to the construction of new buildings as well as the alteration and demolition of existing buildings.

·         The Building Act 2004 has repealed the Building Act 1991 and introduces a number of changes to the law governing building work. These changes are introduced in stages. Some have already taken effect, but others will be implemented over the next few years

·         Building regulations form an important part of New Zealand’s building controls.

·         Building regulations are made under and in accordance with the Building Act 2004 (the Act). The type of regulations that can be made, including the process that must be followed when creating new regulations are given in Sections 400-415 of the Act.

·         The Building Regulations 1992, and subsequent amendments, were made under the Building Act 1991 but are now treated as if they were regulations made under the Act. However, the majority of the 1992 Regulations were revoked on 31 March 2005 by the Building (Forms) Regulations 2004. The only part of the 1992 Regulations continuing in force is Schedule 1 containing the Building Code.

·         All new building work in New Zealand must comply with the Building Code. It is a performance-based code, which means it states how a building and its components must perform as opposed to describing how the building must be designed and constructed

5.  In relation to weather tightness, what are the 4 D’s?

·         Deflection – keeping water away from potential entry points

·         Drainage – providing means of removing water that does enter.

·         Drying – allowing any remaining moisture to be removed by ventilation or diffusion.

·         Durability – providing materials with appropriate durability.
