Kiwi Joseph Parker concedes his career is at a "make or break" point, as he prepares to step into the ring against Faiga Opelu in Melbourne on Wednesday.

"There's no progressing, and no climbing the ladder if you lose this fight," he told Newshub.

"If you lose this fight, it's goodbye Joe - the end of your career.
