*Fly a CAA examiner over to aussie and do in a Sim (already rated or initial typed)
If you are rated on any of the aircraft that Air NZ fly, you can hire the sim from them too.
Does it have to be a full motion sim for the test?
Having an ATPL licence is not the godsend you think it is.
Just because you might not have one you think that obtaining that holy grail will make all the difference to your employability. The reality is similar to a 200hr CPL going for a MEIR, unless you are rated on a popular type and ready for Captaincy it really is not the magic ticket.
I wouldn't bother spending the extra cash.
