Immigration New Zealand says if a young Fijian immigrant does not return home voluntarily tomorrow he may never be able to re-enter to New Zealand for a crucial operation.
Sanil Kumar's visa was not renewed in July and he has been given a 28-day deadline to leave New Zealand, which expires tomorrow.
Mr Kumar requires a kidney transplant, and the Labour Party has warned the Government that he could die if he was deported.
Immigration New Zealand's acting compliance operations manager Natalie Gardiner said if Mr Kumar left voluntarily he would be able to return on a temporary visa for a transplant once he had raised the funds for an operation.
But if he was deported he would be banned from returning to New Zealand for five years and could also pay any costs associated with deportation.
