The argument I'm constantly faced with on the forum I am referring to is that Australia and N/Z both use AS/NZ3000.
Nev,
I think you may have slightly mis-construed what I was trying to say.
Sure, both Aussie and NZ, use AS/NZS 3000, however that is a wiring standard only, it gives a benchmark as to HOW the work must be done.
New Zealand uses the New Zealand Electricity Regulations, it is this document and this one alone, that states who can and cannot do PRESCRIBED electrical work and the limits thereof.
Aussie does not use the NZ Electricity Regulations, as far as I am aware.
