Ardmore have a pretty average reputation (easily searched on pprune.) I have heard of people taking 6 months just to do a MEIR due to a shortage of Aircraft. CTC sound like a very good outfit, but I dont think they are particually in touch with what a pilot would need to operate commercially in NZ, outside of their organisation (IE the big bad world)
If you want to get industry relative training go elsewhere. Its much cheaper, much quicker and generally has better job prospects at the end. New Plymouth aeroclub and other companies that have a commercial operation attached are good places to start.
