Well, as a New Zealander I think that we appreciate the differences between the various versions of the language pretty well. We are constantly bombarded by media from both sides of the Atlantean Pond, plus we are frequently further polluted by what happens on the other side of the Local Ditch. Moreover, we are frequently subjected to South East Asian versions of our own language, some of which take a lot of assimilation.

Good luck with the thesis, Miia.
