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.
