TTMRA
The TTMRA only applies to "professional" licences. So if you have a ppl you will have to do a formal licence conversion which includes a BFR with a B or A Cat instructor, form filling and a cheque for $NZD50-ish.
For CPL and ATPL conversion you will get the equivalent license or rating that is has been fully issued to you in OZ. I.e ATPL subjects or partial subjects are not covered.
