    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 elements and performance criteria

    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 Safety Manual Electricity Industry (SM-EI) (2004) 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, Hamilton

Please note

    Providers must be accredited by NZQA, or an inter-institutional body with delegated authority for quality assurance, before they can report credits from assessment against unit standards or deliver courses of study leading to that assessment.

    Industry Training Organisations must be accredited by NZQA before they can register credits from assessment against unit standards.

    Accredited providers and Industry Training Organisations assessing against unit standards must engage with the moderation system that applies to those standards.

    Accreditation requirements and an outline of the moderation system that applies to this standard are outlined in the Accreditation and Moderation Action Plan (AMAP). The AMAP 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.
