NZ PPL
It is possible to sort out an NZPPL - you don't get one as part of the course if you follow the integrated JAR syllabus, though all of the syllabus items (with the exception of low flying) are covered. There is an aeroclub on the airfield who, worst case, can do it, however as CTC NZ are quiet at the moment there is probably enough capacity for them to do it for you in house. The delaying factor is getting the relevent fit and proper person documentation through the NZCAA and subsequent receipt of the license paperwork, which could take a month to turn up, which might be worth bearing in mind if you are planning on particular visit dates.
