Immigrant advocates fear the closure of Immigration New Zealand branches will make it hard for people forced to deal with their applications online and via call centres.
Immigration New Zealand says the Sydney office has already closed, Dunedin will close and the Wellington, Manukau, Hamilton and Queenstown branches could also shut.
Four other overseas branches are also under review.
National president of the Federation of Multicultural Councils Tayo Agunlejika says some immigrants struggle with the internet and communicating with call centres.
He says Immigration New Zealand should consult with immigrant communities about the changes it is considering.
