My understanding was that there were likely to be problems with the CAA for an aircraft built using Glynn Powell’s moulds possibly because the NZ and CAA regulations are significantly different.

At that time we were part of the EU so I don’t doubt there were EU regs which threw a spanner in the works as well. Now that we are independent again that situation may well change but as stated in a post above the cost of sending a CAA inspector to NZ to sign off the various stages of the build would also be another factor.
