I recognise the narrowness of this debate, but it is worth acknowledging some of the storied history that got us here. Not so long ago, in some people's lives at least, we had a Prime Minister who was also the Minister of Finance and ruled and micro-managed with an iron fist. Rob Muldoon went over to the UK and agreed that the National Airways Corporation, or Air New Zealand, would use Rolls-Royce jet engines instead of General Electric, even though Air New Zealand was not set up to service Rolls-Royce engines. So the people trying to run the business went through the machinations of trying to actually figure out how to land and take off on time and serve their customers and run an effective airline while dealing with the most unconscionable political interference. The reasons that we have an State-owned enterprise (SOE) model, the reasons that Air New Zealand and many other SOEs are operating as private businesses with an objective to their shareholders, is actually to avoid that kind of micro-managing interference that makes it impossible for the directors and management of a company to deliver a useful service to their customers.
