Unlikely to be too much of a shortage of pilots coming through. Since the qualification of CPL/IR's for government (rather than self) funding the schools are very busy.
I think three FTO's have met the criteria, these being Massey, Nelson (out of Motueka) and IAANZ at Christchurch. They are busy! I am unsure whether any operators from Ardmore have the approval, but there are shedloads of students training up there as well.
Perhaps try emailing some of the schools with your questions.
As the schools are busy, there are openings for C Cat flying instructors (post CPL/IR), and you are probably better to explore that scenario rather than thinking about getting straight into the RHS.
