Explanatory notes
1
This unit standard is intended for, but not restricted to, workplace assessment. The
range statements across the unit standard can be applied according to enterprisespecific equipment, procedures, and processes.
2
Safety of personnel and plant must be a priority throughout the assessment. If the
safety requirements are not met the assessment must stop.
3
Performance and work practices in relation to the outcomes and evidence
requirements must comply with all current legislation, especially the Electricity Act
1992 (and any amendments) and any regulations and codes of practice recognised
under that statute; the Health and Safety in Employment Act 1992; and the Resource
Management Act 1991. Electricity supply industry codes of practice and documented
industry procedures included in the current Safety Manual – Electricity Industry:
Requirements for Safety in the New Zealand Electricity Generation, Transmission
and Distribution Industry (SM-EI) (Wellington: Electricity Engineers’ Association), and
occupational safety and health codes of practice. A full list of current legislation and
industry codes is available from the Electricity Supply Industry Training Organisation,
PO Box 1245, Waikato Mail Centre Hamilton 3240.
4
The phrase in accordance with industry requirements is implicit in all outcomes and
evidence requirements in this unit standard.
5
Industry requirements include all asset owner requirements; manufacturers’
specifications; and enterprise requirements which cover the documented workplace
policies, procedures, specifications, business, and quality management requirements
relevant to the workplace in which assessment is carried out.
6
Electric Lines are defined as the structure of works or electrical installations carrying
conductors above or below ground; and includes the fittings used in conjunction with
conductors but does not include fixed wiring.

Consent and Moderation Requirements (CMR) reference
This CMR can be accessed at http://www.nzqa.govt.nz/framework/search/index.do.
Please note
Providers must be granted consent to assess against standards (accredited) by NZQA,
before they can report credits from assessment against unit standards or deliver courses
of study leading to that assessment.
Industry Training Organisations must be granted consent to assess against standards by
NZQA before they can register credits from assessment against unit standards.
Providers and Industry Training Organisations, which have been granted consent and
which are assessing against unit standards must engage with the moderation system that
applies to those standards.
Requirements for consent to assess and an outline of the moderation system that applies
to this standard are outlined in the Consent and Moderation Requirements (CMR). The
CMR 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.
