My impression was absent that building regulations were focussed on earthquakes and not on insulation. Certainly in Wellington in 2009, when i had the time to hang around looking at building sites they were building houses with walls about 8 cm thick made of, well thin bits of wood really. If they fell on you they might not squash you. But they were not thick enough to contain any insulation worth having. And not much new building really.
The other issue is that the detached property, often single storey, is the norm, and of course the least energy efficient option. Kiwis and Aussies despise terraced housing with a degree of venom.
We are renting a newish mid floor flat when we go to N wales and it should be nice and cheap to heat, with minimal amount of surface area
