They are five points astray of sixth-placed Western Sydney Wanderers and face three tough games, beginning with next Sunday's away match against Melbourne Victory.
"We felt a performance like that was coming, but I didn't expect it to come when so many people were missing," Durante said. "Hopefully, we can back it up and keep our finals hopes alive."
Durante says the Nix's remaining senior players also stepped up and joined with co-coach Des Buckingham in praising the contribution of Kosta Barbarouses.
"It was good to see him play so well," Durante said. "He was direct, he took players on, he scored a good goal, got a nice assist and his work rate was good.
"His work rate has always been really good, he just hasn't had the goals to show for it."
Buckingham also stepped in to bat for Barbarouses, who has scored five goals for Wellington this season.
"Kosta has been fantastic for us all season - he's not been given the credit that he's rightly deserved," he said. "When you watch TV, you miss a lot of the work and movement that Kosta does off the ball.
"He's actually done a lot of work for us, he's just been unfortunate in front of goal, but that's starting to come together for him now."
