I would not have the passport (Aus) with me that had the RP in it and was worried they might not let me in as I wld have a NZ passport and maybe they might get a bit sus - I don't know just trying to figure out if they can by scanning my NZ passport realise that I already have an RP (maybe by name/DOB match). All I want is to be able to enter on my NZ passport (with no RP) and just purchase a tourist visa.
