Eric Chuah, founder of market research company Cultural Connections, says a lack of information about Asians and migrants makes it hard for Kiwis to know these communities.
"There's a lot of stats about migrants coming to New Zealand, but once they arrive here we don't know anything about them at all," Chuah said.
The 37-year-old this year left a senior job as head of migrant banking at ANZ earlier to start a social enterprise, aimed at finding more about people in migrant communities.
Migrants make up more than a quarter of New Zealand's population and nearly four in 10 in Auckland.
"By finding out more about migrants needs, Kiwis will be able to appreciate the challenges that they face," said Chuah.
