The 23-year-old looked tired in the 28-27 loss to the All Blacks last week and was replaced by Courtney Lawes for the final quarter in Dunedin.
The Wasps second rower had originally been named on the bench for the series finale at Waikato Stadium in Hamilton. But a hamstring injury has ruled the impressive Geoff Parling out and means Launchbury has now been promoted to the starting line-up alongside Lawes despite coach Stuart Lancaster conceding the Wasps lock was starting to struggle after a long season.
But on the eve of the Test match, which England need to win to avoid a series whitewash, Farrell said Launchbury was raring to go.
"He was gutted to not be starting the match," Farrell said. "After the reviews he knows the reasons why.
"He's licked his wounds a little bit and he's got a chance to start and I'm sure we'll get more out of him because of that initial disappointment. He's chomping at the bit."
The whole England team will need to be on-song if they are to deny the All Blacks a record-equalling 17th straight win.
The tourists have had their opportunities to win both of the Test matches so far but have lacked the composure at critical times which has seen them go down 20-15 in Auckland and 28-27 last week.
To reverse the trend England will need to be clinical to deny the All Blacks opportunities and to convert their own chances into points.
"It's about learning from past performances and knowing how to grab hold of the game by the scruff of the neck and take it all the way to victory," Farrell said.
"We want to win. We want to end this series on a high. The boys have a deep motivation to go out there and prove a point and win a game."
All Blacks coach Steve Hansen suggested on Thursday that England would be in a quandary about their game plan after coming up short when they used their set-piece as the platform for attack in the first Test and then failed again when they tried to play the game at pace last weekend.
Farrell responded with a wry smile. "It's just media talk," he added. "The reality is the game always takes its own path.
"We've got to be in control of our own game. We want to play quick at the right times.
"You've got to be composed at the right times and slow things down when you need to to suit yourself.
"We've got to cut down (our errors) so they can't play at the pace they want to play at."
Farrell also believed the disappointment of the Rugby World Cup loss to France in 2007 and the lessons the group had taken from that experience had made New Zealand the masters of closing out the big games – something England was still learning to do.
"They are the best side in the world at actually getting over the line, like the couple of games against us, the Ireland game and the French game they've played in the last couple of years," Farrell said.
"They are the best at getting over the line because they've been through the experiences of disappointment and they are composed at the right times of the game when it really matters. We can learn a big lesson from that from this tour."
