Adopting the NZ CAR Parts for regs. would be a bloody good start
Oh no it wouldn't. The NZ system is just a thinly disguised American system, doesn't suit the environment at all, and replaced a system that wasn't broken in the first place. It was a mind-numbingly expensive process, paid for by the industry, that has little tangible benefit and ends up costing the end user even more.
All thanks to the highly questionable Swedavia report from the '80s.
Don't go there.
