Explanatory notes
1
This unit standard has been developed for learning and assessment on-job.
2
Achievement of this unit standard does not by itself imply that trainees may legally
perform prescribed electrical work in their own right. Until they are registered and
licensed under the Electricity Act 1992, trainees are assisting, and must work under
the supervision of a Supervisor of Electrical Work when carrying out prescribed
electrical work. If the prescribed electrical work in question is carried out for reward
the Supervisor of Electrical Work must hold a valid practising licence.

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.
