The desire to be world champion burns strongly in 22-year-old Parker and the belief has been helped significantly by his performance in his last fight a month ago - a demolition of experienced American Brian Minto.
Minto is an experienced fighter who went into the bout in South Auckland with self-belief of his own after a victory in a bloody brawl over Shane Cameron, one of Parker's role models, and a bag of tricks picked up during his many years as a professional.
"For me that was a big step up," said Parker. "He was a tough dude and knew a lot of tricks. In the training camp we did everything we could to prepare and after the victory that was a boost for me because everything we did was working.
"To beat someone who beat Shane Cameron and someone who has been around the world and fought different champions, the feeling was cool.
"It gave me confidence in myself and what I can do in the ring and confidence that if we put in the hard work, listen to the coach and follow the plan then everything will fall in place. Probably the highlight of the fight was executing the plan. In previous fights I wasn't able to or didn't follow instructions."
In an odd twist, one of the gravestones facing that of Frazier's is inscribed by the name "Joseph Parker", who died in 1890.
