A migrant from Iran who has been fighting for months to get a tourist visa for his sister has accused Immigration NZ of "unfairly targeting Iranians".

Auckland hairdresser Majid Joshan, 29, is dreaming of a New Zealand reunion with his younger sister Masoumeh Joshan, 23, whom he has not seen for nearly 10 years.

But despite providing what Majid believes to be "strong evidence" to show his sister has enough money to support her stay and strong ties to Iran, his sister's applications for visitor visas have been declined twice in the last six months.
