Line Mechanics

Line Mechanics

From 27 October 2017 there will be four new Line Mechanic classes created to replace the Line Mechanic class which will be disestablished

Electrical workers must re-register in one (or more) of the new classes prior to that date. Most Line Mechanics will receive a grand-parenting offer to automatically re-register in a new class. If you receive a grand-parenting offer that meets your employment requirements, you don’t need to do anything else.

Frequently asked questions

I have been grand-parented Distribution Line Mechanic but I work in Transmission/Traction – or vice versa. How do I get this changed?

Use this application form and apply for a re-registration change by supplying either the appropriate National Certificate or a letter from your employer citing the qualifications and experience you have in the class of registration you require.

Download the Re-registration application form  

Why do I have to re-register when I have workmates that were automatically grand-parented?

Line Mechanics who were registered prior to 2010 have history on their file that shows the type of Line Mechanic they were, so we were able to reinstate that class. Those registered after 2010 were given the non-specific class of Line Mechanic with no indication what area they worked.  Those affected Line Mechanics will need to re-register into the correct class.

Can I be grandparented to Line Mechanic Distribution endorsed?

No, this is a new class of registration and does not cover any work currently within the limits of work of a Line Mechanic. Granting of this registration endorsement requires completion of the New Zealand Certificate in Fault Response and Switching

Enquiries regarding this certificate may be made to Connexis.

What happens if I don’t re-register?

From 27 October your existing class of Line Mechanic will be removed and you would no longer be able to carry out prescribed electrical work.

I am not currently carrying out PEW,  I am still working in the industry and don’t have a current practising licence.  Do I need to re-register?

Yes, this would be advised. There is no cost to re-register if you do so at any time within this practising licence round. But this free offer may not be extended further.

How do these changes affect employer licence holders?

Employer licence holders should update operations manual and train staff appropriately by 27 October 2017. You will be asked to submit a copy of your updated manual with your next licence renewal application.

What does restoration of supply mean?

The restoration of supply is about repairing or replacing fittings following a fault, situation or similar; where power has been lost to an Installation including replacement of mains entry boxes, main switches, bell mouths.

Substation maintainer

What is this class and how do I apply? 

This class is being introduced in response to a new New Zealand Certificate being introduced for those electrical workers working in the supply industry maintaining sub-stations. Currently this work is being carried out either under an employer licence or by those registered in another class but whose limits of work include those of a sub-station maintainer.

If you are currently doing this work under an employer licence but do not hold registration then you may either approach Connexis or apply to the Electrical Workers Registration Board with references and suitable qualifications for assessment and advice on registration requirements.
