"If Whangarei is willing to get more people coming here they have to think about how to educate people here to tell them, 'there are people from another culture coming' and how to work together and respect each other."
The Taiwanese and Singaporean couple said a lack of support services for migrants in Northland could put fellow Asian people off. As an example, they said there is no Mandarin-speaking GP in Whangarei and few options for learning English as a second language.
"Because we have been in New Zealand more than 10 years, the business opportunity presented and we just came up, we don't need a lot of support," Ms Tsai said. "For the new immigrant they need a lot of support ... that's not done enough of."
Asian migrants also simply did not know anything about Whangarei and more advertising was needed, Mr Choo said: "Information [about Northland] is not really translated to other Asian people and new immigrants.
"... So if nobody knows how good it is, they will not come."
He said the city's leaders and residents must consider whether growth from overseas migrants was something they wanted. "We need to ask, are they willing to have more Asian people come in to do business? The structure of the population, the culture and way of doing things will be changed. So first the question is, are people here willing to accept this change?"
