New All Blacks coach Ian Foster has named Richie Mo'unga at first five for the opening Bledisloe Cup test against Australia in Wellington on Sunday.
In his first test in charge of the All Blacks, Foster has opted to retain the dual-playmaking system which Steve Hansen used last year.
Barrett spent the majority of the Super Rugby Aotearoa season at the Blues but did finish the season at first-five, but he was outshone by Mo'unga at the champion Crusaders.
There are no debutants in the starting side, although lock Tupou Vaa'i, No. 8 Hoskins Sotutu and winger Caleb Clarke in line to make their debuts off the bench.
But the most surprising selection in the All Blacks side is Beauden's brother Jordie Barrett being named on the right wing, while George Bridge is on the left.
In the midfield, Jack Goodhue will partner Rieko Ioane while halfback Aaron Smith completes the backline.
In the forwards, Joe Moody, Codie Taylor and Ofa Tuungafasi make up the front row.
Sam Whitelock will play his 118th test, becoming the fourth-equal most capped All Black of all-time alongside Tony Woodcock, and partners
Patrick Tuipulotu in the second row.
Ardie Savea starts at No. 8, with Shannon Frizell and captain Sam Cane completing the loose forward trio.
There is plenty of experience on the bench alongside the three rookies with hooker Dane Coles, props Karl Tu'inukuafe and Nepo Laulala, halfback TJ Perenara and midfielder Anton Lienert-Brown.
All up, there are 17 players that featured in the semi-final defeat to England at last year's Rugby World Cup in Japan.
Foster said he and fellow selectors John Plumtree and Grant Fox had kept an open mind when naming their first test of the year.
"We really wanted to see how players adapted and fitted in and how comfortable they were coming back into the environment and so there were a number of positions that we wanted to keep an open mind about," says Foster.
"We're excited by the group. There's a lot of talent in there and we've got players jumping out of their skin and wanting an opportunity.
"It's been fantastic to come together and know at the end of the week there's a test match.
"There's been a lot of hard work, but the tightness of the group and the desire and the excitement about playing an international game is right up there."
