If I get this idea right - they will only need to push for activation of Civil Aviation Convention article 83bis protocol. Same way as it is done in other parts of the world, it will allow CASA to rubberstamp NZ (or any other country) licenses as valid for a certain NZ operator using VH registered aircraft.
The good example of where it is all going is an abundance of VQ/VP (Bermuda) registered aircraft in Europe. Unties the hands of employers in terms of sourcing the workforce.
