The New Zealand Building Code (NZBC) is a schedule to the Building Regulations
1992. It provides requirements for compliance with the Building Act 2004 when
constructing a new building or altering an existing one. The Building Code sets out
performance standards that building work must meet and covers aspects such as
structural stability, fire safety, access, moisture control, durability, and services and
facilities.
4
Definitions
Acceptable Solutions – step-by-step building methods that are approved as being
compliant with the NZBC (for example, what insulation is needed to comply with
energy efficiency requirements of the Building Code).
Alternative solution – a building design solution that differs totally or partially from
those contained in the Acceptable Solutions, but still meets the performance
requirements of the Building Code. It can be a minor variation from a Compliance
Document, or a radically different design and construction approach.
Industry use – common use in the roofing industry.
Job specifications – refer to the documented information found in construction
drawings, project specification documents, legislation, regulations and codes.
Shingles – is used in this unit standard as a term to include shakes; roof shingles are
coverings designed to protect buildings by having individual elements overlapping
each other. Shingles are made from materials such as asphalt, sawn wood, or
composite materials; shakes are split from timber logs (instead of sawn) and
reshaped by manufacturers, they are thicker at the butt end than timber shingles.

Please note
Providers must be accredited by NZQA, or an inter-institutional body with delegated
authority for quality assurance, before they can report credits from assessment against
unit standards or deliver courses of study leading to that assessment.
Industry Training Organisations must be accredited by NZQA before they can register
credits from assessment against unit standards.
Accredited providers and Industry Training Organisations assessing against unit standards
must engage with the moderation system that applies to those standards.
Accreditation requirements and an outline of the moderation system that applies to this
standard are outlined in the Accreditation and Moderation Action Plan (AMAP). The
AMAP also includes useful information about special requirements for organisations
wishing to develop education and training programmes, such as minimum qualifications for
tutors and assessors, and special resource requirements.
