Derb, there's so much [email protected] spouted about 'test and tag' that I so wish it was never, ever dreamed up!
Since 1990 NZ has followed the rest of the Health and Safety conscious world with this [email protected] that if you test and tag electrical equipment you'll have a lovely safe environment and everything will be rosey in the garden!
Your supply cable is being tested (and tagged) under a standard for 'workplaces'. That's workplaces, not domestic.
There is some argument that campsite owners want to keep their other clients safe - and who can disagree with that, but along with your WoEF your supply lead will be tested (and repaired no doubt if it were dangerous). Therefore it's not a leap of imagination that it to is good for 4 years.
And this brings me to the other point about 3760. The frequency of re-testing as set out in that wonderful (?) standard is 'indicative'! Not mandatory.
The number of people who tell me that they have been told 'X' has to be re-tested every six months, (and usually by one of the numerous T&T outfits), is staggering.
Hardly anyone uses a risk matrix, let alone applies common sense.
I'll rock your world now. I'm going to suggest that a owner of, lets say, oh a drill and extension lead, is a lot more likely to look after that, whereas lets say a hire company where anyone from day to day will use a similar drill and extension lead.
So the re-test for the owner operator should be a lot longer than the hire company. And by lot longer I mean years not months! (because they probably look after it better and seeing as it will be them that get the electric shock if it's faulty, more likely to repair it when needed).
I think your inspector needs to have another read of 3760!

Generally the use case is small, and sparkies won't typically be buying the bits in 'packages' from trademe....
