Paul, that's a very good point you brought up about the availability of cable, I've seen I don't know have many installations done with Flex,by DIY people.
It seems to be a mentality, of what ever you can get(to do the job), will do.
And the regulators haven't really helped either, they send out all these Codes of Practice and so forth, but, nowhere have I ever seen a New Zealand guide to Wiring, since the new Regulations allowed Homeowners to do thier own wiring, so how the Hell are they supposed to know?.
