I'd need about a week observing how it works internally before I could answer that with any reality. Certainly I'd get the registration records onto computer as a priority, since that seems to be quite a bottleneck. Biennial registration as raised here is also an option, although perhaps unnecessary if the system is fixed.
I'd also lobby government to introduce a way for low-end flying to happen again. The NZ system seems to have a good balance of care and freedom, and would be more likely to succeed than FAR 103 style, which only exists due to its age and user base. However, legitimizing unlicenced solo flight over remote private land is a possibility, and I'm sure it happens a lot in country areas.
Security requirements for small country airfields have gone mad since 9-11, they need to be backed off. We all know that was a con job by now, or should.
Meh. Don't get me starterd, I'm retired.
