"I was taken along to watch a Golden Gloves tournament and got hooked on it. I was then taken to the Ringside Brothers Gym where I met up with TK [Kelly] and I've been with him ever since ... I look up to him."
The 1.85m tall Pettaway has been the most successful of Kelly's five professionals.
"I've watched him grow up and he has exceeded my expectations," Kelly said.
Kelly was a professional boxer until he lost his leg while working in a coin-making factory.
While Pettaway enjoys basketball, his daughter is named after Chicago Bulls legend Michael Jordan, American Football is his next fancied sport after boxing and the Pittsburgh Steelers are his favourite team. The Steelers feature among his tattoos.
So does his mother and a biblical message ... "I can do all through Christ."
Like Parker, Pettaway, boasts strong Christian beliefs. Fans of Parker reckon Pettaway will need the most help from the bloke up above because Parker is ranked 10th in the WBA and and 12th in the WBO, while Pettaway isn't ranked by any of the four major sanctioning bodies.
The diplomatic Pettaway said he hadn't picked up any vibes suggesting it was going to be a one-sided battle in favour of Parker during his week of promotional visits on his first tour of New Zealand.
Four wins from as many bouts last year and some improved sparring sessions have Pettaway's confidence levels exactly where he wants them.
Pettaway has worked with 2004 US Olympian Devin Vargas (18-4) and 7-0 cruiserweight Paul Parker for three months, a step up for him. His only professional loss was a TKO one against Russian Magomed Adbusalamov in March, 2012.
He returns home on Monday and will return to Auckland 10 days before the fight.
"I'm hoping a win against Parker will open further opportunities for me. I've got no other fights booked yet ... my total focus is on Parker," Pettaway said.
"I reckon I've got two more good years as a professional ... there could even be more depending on what doors open after the Parker fight."
Despite missing some key stages in the development of his daughter Pettaway has enjoyed his first week on New Zealand soil.
"It's a nice beautiful country, the landscape in particular."
Those in the know within the boxing fraternity believe Pettaway won't be leaving the country with the same feelings on March 6.
