Dick,
Just a note of caution about quoting Ardmore NZ as a shining example...
Landing fees are my third highest expense!
$15 + for a full stop and rents have quadrupled over the last 5 years, $350 a month for an old standard shared hangar...
Cross runway closed... and guys leaving left right and centre for other, more friendly places NZTG.
Current owner against aviation $$$$ are the only important thing.....
It's a shambles !
