Joseph Dennis Parkeris a New Zealand professional boxer. He held the World Boxing Organization (WBO) heavyweight title from 2016 to 2018.
At regional level, he has held multiple heavyweight championships, including the WBO Oriental, Africa, and Oceania titles; as well as the PABA, OPBF, and New Zealand titles. As an amateur, he represented New Zealand at the 2010 Commonwealth Games in the super-heavyweight division, and narrowly missed qualification for the 2012 Summer Olympics.
Parker turned professional in July 2012 with Duco Events in Auckland, under the tutelage of Sir Bob Jones. After defeating Andy Ruiz for the vacant WBO title, Parker became the first heavyweight boxer from either New Zealand or the Pacific Islands to win a major world championship.
