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.

Definitions
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.
Company requirements – include the policy, procedures, and methodologies of the
company. They include requirements documented in company and site health and
safety plans, quality assurance documents, and contract work programmes.
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.
Manufacturer recommendations – refer to product information and product data
sheets provided by the manufacturer of any given product.
Notifiable work is as defined in A Guide to the Health and Safety in Employment Act
1992 (Wellington: Department of Labour, 2003); available at
http://www.osh.govt.nz/order/catalogue.
Site procedures – refer to the procedures which are required to be observed for safe
work practices at a particular site.
