New Zealand heavyweight boxer Joseph Parker has climbed to No 15 on the WBO's latest rankings.

Parker's significant rankings rise with the respected organisation comes on the back of his seventh round win over American Brian Minto in Auckland two weeks ago.

New Zealand light heavyweight Robbie Berridge has also moved up with the WBO, lifting a spot to No 9 to keep him New Zealand's highest-ranked professional boxer.

Both Parker and Berrdige were set to fight in the United States on August 9 on a Main Events promotion in Bethlehem, Pennsylvania, that would be televised live in both America and New Zealand.

Independent rankings based on a points system run by BoxRec and covering fights in all organisations have Parker ranked No 30 in the world heavyweights and Berridge at No 16 in the light heavyweight division.
