Blues captain Keven Mealamu said that while the Blues were dissapointed to start their Super Rugby season with a loss they will move on.
The Blues started strongly and went out to an early lead but their line out and discipline cost them and the Crusaders crept back into the game.
"Games like this between the Blues and Crusaders come down to inches and that's what happened tonight," Mealamu said.
"We'll take what we can from this and get better next week."
The Blues lost by a point so they will at least take a a losing bonus point from the match.
The Crusaders were outscored by two tries to one but Dan Carter's replacement at 10 Tyler Bleyendaal only missed two kick from seven attempts and gave his team a one point lead over the hosts.
The Blues could have won the match had Piri Weepu's drop goal not been charged down in the last act of the game.
Crusaders stand in captain for Richie McCaw Kieran Read admitted after the match that they were fortunate to win the match.
"We were lucky to get away with it," Crusaders captain Keiran Read said.
"I don't know how we did it but I'm glad that we did.
"We managed to put some pressure on them down their end of the field which led to penalties to us and we were able to kick them."
The Crusaders play the Highlanders in Dunedin and the Blues travel to Hamilton to face the Chiefs next week.
