About this course

Anyone wishing to register as an electrician in New Zealand must meet the criteria set out by the EWRB. This course builds your knowledge of electrical theory essentials and gets you ready for your Electrical Workers Registration Board (EWRB) Electrician Theory examination.

Learn the theory that backs up the practical work you do every day. Our tutors know their stuff and will guide you through 80 hours of training designed to get you exam-ready with knowledge you'll actually use on the tools. After you finish your block course, we'll sort your ASPEQ examination booking at a time that works for you. You must attend 80% of the course for us to approve your exam with ASPEQ.

Course format and requirements

Complete 80 hours of self-study then attend a 5-day theory block course (Monday to Friday, 8.30am-4.30pm).

Prerequisites

We highly recommend doing the Regulations course before this Theory course. There are no prerequisite requirements for the theory course and examination. However, to be eligible for registration (unless exempted by the EWRB), candidates will need to demonstrate to the EWRB that they have completed 8,000 hours practical training/experience in the work of an electrician while holding a Trainee Limited Certificate (TLC). In addition, practical stage assessments and electrician registration examination pass will be required, as defined by the EWRB.
