the first round and suffering cuts above both eyes, Cameron knocked Mirovic out in the eighth round via a left hook to the Australian's forehead to again retain his WBA Pan African title. Once again a challenge was extended to Tua, with Cameron's camp offering the fellow Kiwi NZ$250,000 to step into the ring. After the match Cameron's New Zealand manager Ken Reinsfield stated "We'd fight Tua in a heartbeat, but you can see why Tua doesn't want to fight him." Cameron added a third title to his collection on 28 June 2007, with a first-round TKO win over a jet-lagged Brazilian Jucimar Hipolito for the vacant World Boxing Organization Asia Pacific Heavyweight title. Jucimar was a late replacement to Kelvin Davis who broke his back after jumping off a bridge to avoid a car in a night time training run. On 2 November 2007, Cameron suffered his first professional defeat at the hands of Friday Ahunanya. Cameron lost by a 12th round TKO decision after he was sent to the canvas twice after Ahunanya opened up bleeding cuts above Cameron's eyes. With this loss, Cameron surrendered all the titles he previously held. Cuts to both eyes hampered his vision (cut right eye in round 3, cut left eye in round 9) and ability to avoid punches from his opponent in the later rounds. Even heading into round 12, according to commentators, he was leading on points. Cameron's management still had high hopes for his future and stated that they would allow three months for the cuts to heal properly before his next fight. On 11 April 2008 Cameron fought American Heavyweight Jonathan Haggler, Haggler's record being 18 wins and 2 losses. Cameron knocked out Haggler in the eighth round. Winning the fight meant Cameron claimed the WBO Oriental, WBO Asia-Pacific and IBF Pan-Pacific belts. He bled only slightly from above his left eyebrow, which had been recently operated on. Cameron then fought American Kevin Montiy on 28 June 2008 knocking him out in the 5th round. With that win Cameron defended his IBF Pan Pacific heavyweight title and his WBO Oriental heavyweight title. Cameron later stated "The Montiy fight was one of my best performances to date. I had my best camp, great sparring and my conditioning was great as always". A fight between David Tua and Shane Cameron took place in Hamilton, New Zealand on 3 October 2009.
