About Electrical Apprentice (EWRB)
Becoming a registered electrician in New Zealand means completing an apprenticeship and a Level 4 electrical qualification, passing the Electrical Workers Registration Board's competence examination, and holding a current practising licence: renewed every two years with continuing professional development. The work itself runs under the Electricity Act 1992, the Electricity (Safety) Regulations 2010 and AS/NZS 3000. Asessly practises ten knowledge areas across theory, the wiring rules, protection and earthing, safe isolation, testing and certification.

Common questions
About Electrical Apprentice (EWRB) and how Asessly prepares you for it.
Questions about Asessly itselfWhat does Asessly cover for electrical apprentices?
The knowledge behind New Zealand electrical registration: the Electricity Act 1992, the Electricity (Safety) Regulations 2010, and the wiring rules in AS/NZS 3000, alongside the calculations and fault-finding logic the trade depends on.
Does this reproduce AS/NZS 3000?
No. AS/NZS 3000 is a copyright standard. All questions are original Asessly content and do not reproduce the standard itself. You still need proper access to the wiring rules.
Does Asessly lead to EWRB registration?
No. We are not affiliated with the Electrical Workers Registration Board, we do not deliver the EWRB competence examination, and Asessly practice does not lead to registration or a practising licence.
What kinds of questions are in the bank?
A mix of regulation knowledge, applied calculation and fault reasoning, because electrical assessment tests whether you can apply a rule to an installation rather than recall the clause number it came from.
How are EWRB examinations sat?
Through Aspeq. You need an EW number to register, then you book online. Examinations run throughout the year at Aspeq facilities and results are released within 24 hours. Separately, a licensed electrical worker must complete a Board-approved competence programme every two years, and that has to be done before a practising licence can be renewed.
How large is the question bank?
It is being built towards 350 questions, one of the two largest banks in the catalogue. The card always shows the number actually published rather than the target.
