Why do you have this problem with PPL. It is not just PPL who transit in the open FIR, many CAT operations are in this category of airspace and also remember that a large part of GA is other than PPL. So do you want the airspace cleared for your unknown, undetermined manoeuvres at high speed? Grow up little man. Perhaps the RNZAF masters saw something like you running it and decided to act in the best interest of everyone!
