Definition
Infrastructure pipelaying refers to the installation of infrastructure pipes, fittings, and
associated structures in the road and elsewhere, normally beyond the boundary of
private property. Infrastructure pipes include sanitary sewage and stormwater, and

telecommunications. For the purposes of this unit standard it does not include the
commissioning of the pipes or the installation of services they may house.

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.
