Super 14 era (2006–10)
In 2006, the Super 12 became the Super 14, with the addition of two new franchises, the Cheetahs and the Western Force. By the last round of the 2006 season, the Bulls, along with the Brumbies and Sharks were all in contention to take the fourth and final position on the ladder to make the semi-finals. After the Brumbies were defeated 33 to 3 by the Crusaders, the Bulls or Sharks could mathematically take the fourth spot. The Bulls defeated the Stormers at Newlands in Cape Town 43 points to 10, which ensured they went through to the semi-finals. The Bulls travelled to Christchurch where they were defeated 35 to 15 at Jade Stadium and knocked out of the finals.
The Bulls lost their first game of the 2007 Super 14 season, going down to the Sharks in Durban 17 points to 3. Entering week 14, the last round of the regular season, the Bulls were chasing an unlikely 72-point win over the Queensland Reds in order to move into second place and get a home semi-final. At Loftus, the Bulls defeated the Reds 92 points to 3, with the 89-point margin of victory setting a new Super rugby record. The Bulls ran in 13 tries with four players getting doubles and Derick Hougaard kicking 11 conversions. The Sharks finished first, so it became the first time that both home venues in the semi-finals was in South Africa.
The Bulls defeated the Crusaders in their semi-final by 27 points to 12, with Derick Hougaard kicking eight penalties and a drop-goal. The Sharks ensured a home-final in the 2007 Super 14-competition by defeating the Blues with a scoreline of 34–18.
When the Bulls met the Sharks in the Super 14 final at the Absa Stadium in Durban the match turned out to be a tight, nervous affair with the Bulls initially being guilty of indiscipline and making a lot of mistakes. The Sharks carried a 14–10 advantage into half-time after a JP Pietersen try cancelled out one from Pierre Spies. The second half of the match was just as nail-biting, with the Bulls gaining the ascendancy in the match, but failing to turn their rising amount of possession into points. A Derick Hougaard penalty closed the gap to 14–13, after which the Bulls made several onslaughts on the Sharks line, only to lose the ball at critical stages. Their match looked to be all but over for the Bulls when Albert van den Berg barged over the line for a Sharks try two minutes from full-time to stretch their lead to six points. However, François Steyn failed with the conversion attempt, and the Bulls restarted with barely seconds on the clock. After regaining the ball from the kick-off, play went through several phases before Bryan Habana received the ball on the right wing. He cut infield and scored the most dramatic of match winning tries, more than a minute after official play. The try was converted by Derick Hougaard and the Bulls won the match 20–19. In 2009 the Bulls again won the Super 14, defeating the Chiefs 61 – 17 in the final in Pretoria.
In 2010 the Bulls again finished top of the log by beating the Crusaders in a home semi final to secure a home final. Because the FIFA World Cup was being hosted by South Africa that year and Loftus was included as a venue, they had to play the semi and final in Soweto, a first in Super Rugby history. The Stormers had beaten the Waratahs at home and would face off with the Bulls in the final. The Bulls won the final once again in dramatic style when Francois Hougaard sidestepped the Stormers fullback Joe Petersen to score an impressive try.
