Chiefs boss Dave Rennie was a relieved man after his side clinched a late 19-17 victory over the Brumbies in New Pymouth on Friday.
In a game which saw the lead change hands several times, Aaron Cruden held his nerve and landed a penalty in the dying moments of the match which allwed the Chiefs to ecure their second successive victory of the tournament.
"We played with a lot of character but there was a fair bit of frustration out there," said Rennie.
"We just didn't build for long enough, we got penalised a lot at set piece and had trouble getting our game going, especially in the second half.
"So to come back and win those tight games, it's massive and I'm really rapt with the outcome."
The Chiefs' depth was severely tested even before the match kicked off. Injuries to All Blacks duo Sonny Bill Williams and Sam Cane forced them to withdraw before kick-off with Seta Tamanivalu and Tevita Koloamatangi coming in to the run-on side as their respective replacements.
And the 2012 and 2013 champions suffered another setback when Koloamatangi limped off in the fourth minute with an ankle injury.
"Sam had trained all week but he made a couple of tackles yesterday at the captain's run and re aggravated the injury, so we didn't want to risk him," added Rennie.
"It was the same with Sonny, we just didn't want to risk him. But we will expect them both to bounce back and be right next week."
