Be aware that doing your ATPL flight test in the old mojave will cost you well over $10,000 ! as the flight examiner will require you to have over 10 hours on type, which is fair enough I guess but it goes for a thousand dollars an hour, which would seem a bit excessive for an old chieftain! You'd be better trying to find someone who can do you a sim ride in something you're typed on. Either that or convert your ICAO ATPL to an Australian one, then use the TTMRA agreement to bring it over to an NZ licence.
