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 industry
specific equipment, procedures, and processes.

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 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 include the current version of the Safety Manual – Electricity Industry
(SM-EI) (Wellington: Electricity Engineers’ Association). 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.

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.
