Us or them?

Many of my friends in New Zealand with Korean heritage as well as I are “classified” as 1.5 or 2nd generation Korean New Zealanders by the society. Does that make us Koreans? New Zealanders? Or both? And can we count on the society to treat us the same as everyone else?
While living as one of Asians in New Zealand, I have noticed how some people could mix well into both host people of New Zealand, commonly known as Kiwis, or could only mix into people with the same cultural and ethnic grounds without being assimilated among Kiwis.
The high school I went to had approximately over 70 Korean students comprised of both international and domestic students, the domestic Korean students included both first generation, many of them whose family immigrated to New Zealand and second generations, born in New Zealand, often lacking in language and cultural understandings of their origin country. What I have observed among the Korean students was that while it seemed that there were 2 types of students, the first type being a mix of 1st and 2nd generation Korean students who were able to mix with the Kiwi students in both school and outside of school. Hence the other type being a mix of 1st and 2nd generation Koreans who chose to mix with only Korean students.
I believe the reason that accounts for these differences is ‘eurocentrism’. Eurocentrism refers to an approach that takes European values, judgments, beliefs and cultures as normal, natural and ideal hence making the European values central and dismissing others to the periphery. Hence the students who only mix with the Koreans believe that due to their appearance, culture and language barrier, it is hard for them to blend in with the Kiwi students. In another words, this can be seen as confusion in identity. Such confusion in identity is a serious matter especially to immigrants as self identity as well as how the others identify a person will alter how the society treats a person. The fact that identity matters in such situation shows that eurocenterism applies in our everyday life.
