Peter Fury, the father and coach of Joseph Parker's next opponent, English heavyweight boxer Hughie Fury, has been denied entry to New Zealand for May's WBO world title fight in Auckland.
Fury's application for a visa has been rejected by Immigration New Zealand on character grounds.
He was jailed for ten years in 1995 for possession and intent to supply amphetamine.
In 2008, Peter Fury was sentenced to another two years for drug-related money laundering.
In a statement, Immigration New Zealand area manager Darren Calder said the case "was fully considered and all representations submitted on Mr Fury's behalf were taken into account before a decision was made to decline his request".
