This chapter explores the re-ethnicization process among newer-generation Korean New Zealanders, who reconnect with their Korean identity after early assimilation as “Kiwis.” This shift often begins in high school or university, driven by co-ethnic friendships, experiences of racism, and increased cultural confidence. Online platforms and the Korean Wave (Hallyu) also strengthen ethnic pride and foster connection to heritage. While re-ethnicization is partly shaped by social exclusion, it increasingly reflects a positive assertion of identity in a multicultural environment. Participants actively negotiate their Korean and Kiwi identities, drawing strength from shared experiences and evolving cultural landscapes. This chapter reveals how immigrant youth navigate identity formation not as a linear path but as a dynamic, relational, and emotionally grounded journey.
