Bulls head coach Nollis Marais said they should have taken the bonus point in their 45-25 victory against the Rebels in Pretoria.
Despite being 42-3 ahead at the first few minutes of the second, the Pretoria side failed to secure a bonus point for scoring three more tries than the Australians.
The new system dictates that in order for the winning side to receive a bonus point, they will have to outscore their opponents by three tries.
"Ja, 10 to 20 minutes into the second half, we let them back into the game when we should have taken the bonus point," Marais told Business Day Live.
Bjorn Basson crossed the whitewash three times with the home side leading the try scoring tally by six tries to none.
The visitors scored in quick succession, dotting down three times in a space of ten minutes.
A fourth Rebels try late in the match ensured that the home side were denied the bonus point.
Despite being content with the end result Marais condeded that they should have walked off the field with five log points.
"We are happy with the win, but we should have finished it off and taken the bonus point," Marais said.
"It is not good when you find yourself 42-3 ahead and then allow them to come back."
Adriaan Strauss agreed with Marais that they should have finished off with a bonus point, the captain was however pleased with their overall structure.
"It felt really good to win at Loftus and to play a good brand of rugby," said Strauss.
"But we needed the bonus point. Although we are happy with the win, we let it slip when it comes to the bonus point."
The Bulls will have a one week break before they face the Sharks at Loftus.
