WE are building a Lockwood house for clients at the moment and the electricians are using triple plating. They have to as there is only one 22mm hole thru the boards to the light switch.

I am not a sparky and I don't do house wiring. But I have designed and made tens of thousands of transformers, mostly for large power supplies and power plants (e.g. the New Plymouth gas plant). The power for most of Auckland goes through my transformers. The water heaters in Auckland are controlled by a large toroidal transformer that I made. The old DSIR used a standard toroidal current transformer that I made and calibrated. It will still be in use somewhere.

Normal for all solid timber wall houses. I have also used it to fit a switch into a cavity slider door frame

They dont change that often. We are still using the wiring rules from 2007, there is a "new" set from 2018 but it is not yet cited into law. The rulebooks arent that expensive to buy in print, unless you are buying alot at once, but we have free access to them online. It is true that most wouldnt wire in 3plate these days, but it is still legal to.

This^^^^ The last substantive change to the body of the ESR was in December 2013. The current, cited version of the Wiring Rules is "AS/NZS 3000:2007 + Amendments 1 & 2" which was included then.
Eight years isn't that "often".

It is legal in New Zealand and still used.
