He made his television debut at the 2007 PDC World Darts Championship as a qualifier, having beaten almost 100 players to win the South African Masters and thus earn his place at the Circus Tavern. He beat Steve Maish in the first round and then conquered established pro Peter Manley in round two, but bowed out in the last 16 to Darren Webster. Havenga became a popular figure during the World Championship, his unique celebrations while winning a leg, or even hitting a 180, led comparisons to Cliff Lazarenko and a fan-base, who call themselves the "Havenga Boys". However, he has since struggled with a shoulder injury and his ranking has since fallen to 500, after the £8,500 he earned at Circus Tavern, was wiped off in 2009 due to the two-year-cyclical rule of the PDC Order of Merit.
