hi! i'm from new zealand, and if it's NZQA approved then it's legit, therefore meaning it will be accepted in the US and everywhere else i assume. i think the problem would be will it be the equivalent to an MFA in the US. for me, i tend to think it's all pretty much the same once you get to a university level, i mean i know in the US a bachelor's degree is often 4 years whereas in nz it's often 3, but at the end you get the same qualification. thus i wouldn't worry about it being accepted or not unless you need an MFA to get into further studies, in that case, you should check out world education services. good luck with your studies in new zealand!
