Kiwis across the Tasman are modifying their accents because they're sick of being picked on.
A University of Canterbury researcher says while their home loyalties will emerge during sporting contests, many kiwis try to fly under the radar most of the time - choosing to be proud of their heritage when the occasion demands.
Rosemary Baird has done a doctorate thesis on New Zealanders living in Australia.
She says most realise gradually that although New Zealand still claims its national loyalty, over time Australia has become home.
She also found most kiwis dislike Australians' negative attitudes towards indigenous Aboriginal Australians and pride themselves on New Zealand’s supposedly superior race relations with Maori.
Rosemary Baird also found the view that New Zealanders migrate for economic reasons is one sided, and fails to take into account complex motives for leaving.
