Explanatory notes
1
This unit standard can be assessed in a workplace environment, or in a training or
educational environment if simulated equipment and examples are able to be
provided, or in a combination of both environments.
2
Safety of personnel and plant must be a priority throughout the assessment. If the
safety requirements are not met the assessment must stop and the candidate will be
assessed as not yet competent.
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 subsequent amendments, and any regulations, codes of practice
recognised under that statute; Health and Safety in Employment Act 1992, the
Resource Management Act 1991, and their subsequent amendments; electricity
supply industry codes of practice and documented enterprise procedures. These
include updated versions of Safety Manual – Electricity Industry (SM-EI) Wellington:
Electricity Engineers’ Association.

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.
