Manying Ip, the professor of Asian studies who led the project, described this as "surprising" and said the finding contradicted earlier assumptions that older Chinese migrants were more conservative and therefore felt more attached to their homelands.
"The finding is surprising in that it contravenes accepted migration and acculturation theories," she said.
"It indicates that the younger cohort are more attached than their older counterparts to their native homeland and feel their identity is more Chinese than anything else."
Professor Ip said the finding carried "significant implications for future interpretation of migrants' sense of allegiance and their acculturation process".
"China's rising status as an emergent world power would likely impress young patriotic Chinese much more than older counterparts, who may have had negative first-hand experiences [of] the People's Republic."
The study also found Chinese who first came here as students felt more attached to the country, only 44 per cent of those with New Zealand degrees claiming homeland identity.
Those with a local degree were also more likely to stay. Chinese national Cherry Li, 27, who first came to NZ as an international student in 2002 and now has permanent residency, said "family ties" were a key reason she still felt more Chinese than Kiwi.
"I feel very strongly for New Zealand, but China is still home for me and where my parents and other family members are," she said.
"If there is ever a conflict ... and I have to choose one country, I will still go for China as I am Chinese."
Ms Li, a marketing executive, said she was reluctant to become a New Zealand citizen as it would mean giving up her Chinese passport because China, unlike Taiwan and Hong Kong, does not recognise dual citizenship.
Local-born Chinese community leader Kai Luey said negative attitudes towards Chinese by "mainstream society" made it difficult for many Chinese migrants to feel a total sense of belonging in their adopted homeland.
"Feeling accepted isn't just about attending lantern festivals or eating Chinese food, you got to also accept them as desirable neighbours and employees ... New Zealand has still got this little Britain in the South Pacific syndrome."
