"As far as the co-captains, all I'm wanting to establish there is there's a shared responsibility amongst those two individuals, but amongst the whole group, to get a job done on what's going to be a really challenging tour," said Kearney.
"Both guys have made wonderful contributions to the jumper. The way that Adam's finished this year off, everyone would have seen in his performances, particularly through the finals series, and he's been wonderful for the Broncos all year.
"He's seen as a real leader of the Kiwis group and Issac's the same. He's come a long way over the course of his Kiwis career."
Luke's appointment could be the making of the 2016 Warriors rake, who has long been a leader and key playmaker within the Kiwis, but struggled with a reputation for ill-discipline.
The 28-year-old former South Sydney No9 has been a regular attendee at the NRL judiciary in recent seasons and missed the Rabbitohs' 2014 grand final win through suspension.
He was fortunate to escape a ban for a shoulder charge towards the end of this season, before being ruled out of his last games for the club on a similar charge only a couple of weeks later.
Despite Luke's past problems, Kearney believes the co-captaincy role will bring out the best in the 33 test veteran.
"I bloody hope so," he joked.
"I believe it will. He understands there's a real challenge in front of us, and I made him aware of that last night, that his leadership needs to be really spot-on.
"I don't see there being a very big issue there. I know informing Issac last night, he was really excited at the opportunity to help lead the side with Adam, so I'm sure he'll be fine."
The influx of new talent excites Kearney, who shrugged off concerns over the fact that Lolohea is the only member of the squad to have played in the halves this season.
"I'm really excited to have the opportunity to work with Tui and Jordan Kahu, Sio Siua, Curtis Rona's another one who's had a wonderful year, so it doesn't bother me at all because I know the energy and the strength of the group will drag those young guys with them."
Blair revealed his shock upon hearing the news of his co-appointment from Kearney on Wednesday evening, and said he had sat on the news overnight without informing his family.
"I was a little bit nervous. Obviously it's everyone's dream to be the captain of your country, at the same time I was a bit excited and I was lost for words as well," said Blair.
"To be honest I haven't told my family. It still hasn't really sunk in. My wife knows and my next call will be to my mum and to my brothers and sister in Melbourne."
Kiwis squad: Gerard Beale, Adam Blair, Jesse Bromwich, Lewis Brown, Alex Glenn, Tohu Harris, Peta Hiku, Jordan Kahu, Shaun Kenny-Dowall, Tuimoala Lolohea, Isaac Liu, Issac Luke, Ben Matulino, Sam Moa, Jason Nightingale, Kodi Nikorima, Kevin Proctor, Curtis Rona, Sio Siua Taukeiaho, Jason Taumalolo, Martin Taupau, Roger Tuivasa-Sheck, Dean Whare
