sorry long post, but bear with me...
At the risk of stating the obvious, it sounds like you have your CPL and are looking for a place to complete a Ccat. If this is the case and you are not starting from scratch.... FYI
A handy piece of information for you Bean is that AFS run a Ccat course from which they select their instructors and only AFS students are selected for this course. It provides opportunity for progression for their students, but, unfortunately means others such as yourself have even fewer options.
I have some experience at Ardmore and if we were to cut out AFS then from those that are left, my observations tell me the likes of Eagle and Airline Flying Club fall below par. AAC is a better option, the people there are friendly and helpful and if it is indeed NZQA then i'd say go for it.
AAC actually has a couple of people studying for a Ccat at the moment so you would be amongst good company.
I have to reiterate flyboy's first comment.... tomorrow's friday, do it.
