The Ulster second-row combined effectively with Donnacha Ryan in the narrow second-Test loss to the All Blacks.
And he believes the squad are more than capable of elevating their performance for the second week in succession.
Tuohy said: "We worked extremely hard to put ourselves in a position to win it. As a collective, we are disappointed that we didn't close it out.
"The focus this week is on delivering another big performance at the weekend."
The Bristol-born lock's outing in the second Test was much improved on the opening defeat by the All Blacks at Eden Park.
He certainly ruffled Kiwi feathers on more than one occasion and drew the ire of Adam Thomson and Ali Williams as the Irish pressed for a first ever win against the world champions.
Tuohy said: "I was much more happy with my performance at the weekend than the one before.
"From myself and the other lads, there is more to come. We will be looking to go out on Saturday with all guns blazing."
