The Blues looked on track to record their first victory over the Crusaders since 2014 and their first away from home since 2004 after Rieko Ioane burst through a gap to rampage over the line and give the Blues a 5 point lead.
Otere Black lined up the simple conversion, for his standards, to stretch the lead to a converted try but Crusaders' centre Braydon Ennor had other ideas.
The Crusaders' man charged down Black's kick and the Crusaders reacted quickly with Richie Mo'unga taking the kick off quickly.
The charge down from Ennor sparked the Crusaders comeback with Mo'unga regathering his kick off with the Blues just able to survive the onslaught and clear into touch.
But the damage had been done and the momentum had swung as Richie Mo'unga's double-pump pass to George Bridge saw Mitchell Drummond cruise through for a try with Mo'unga adding the extras and another penalty from the tee.
