Career
Campbell was first attracted to taekwondo as a child after watching The Karate Kid but initially struggled at the sport. He broke his arm seven weeks before the Olympics, but it healed in time for him to participate. In July 2009 Campbell and his business partner, opened a brothel in Auckland so he could finance his training towards his aim of competing at the 2012 Olympics in London, England.
His 2008 Olympic campaign had cost $150,000 and Campbell hoped to raise the $300,000 that he estimated he would need for the 2012 Olympics.
Prostitution in registered brothels is legal in New Zealand and Campbell described what he was opening as a high class escort agency. Campbell planned to take 2 years off from taekwondo in order to work full-time before returning to training in 2011.
However it was reported that his choice of business might count against him in being selected for the 2012 Olympics. At the 2012 Games he was knocked out in his first fight 6-10 by Hryhorii Husarov.
