cos they don't and won't be able to meet the requirements for an ATPL
Prob depends on where the ATPL is issued. I think you're correct regarding an NZ ATPL not sure about anywhere else. Remember NZ requires a flight test in a pressurised aircraft for the ATPL issue and this fact alone usually means some numbers of P in C hours above the basic CPL issue.
I don't know for sure what they do in OZ but some parts of the world give out the ATPL to CPL holders when they have the exams and the hours which seems a bit weird, since they don't dish out PPL's and CPL in the same manner.
