Barrett, who will win his 149th cap, surpasses Richie McCaw to become the second most-capped All Black behind Sam Whitelock. Richie Mo'unga returns at fly-half to rekindle the partnership that guided New Zealand to the 2023 World Cup final, while wing Fehi Fineanganofo and flanker Anton Segner earn their first Test starts.

The selection continues Barrett's remarkable renaissance after he was omitted from the first three Nations Championship matches this year. Injury opened the door during the Bledisloe Cup and the 34-year-old full-back seized his chance, forcing his way back into Rennie's plans.

"Beauden brings such valuable experience and is massively respected by us all. Captaining the All Blacks in a Test is an honour that I know he doesn't take lightly, so it'll be a proud day for him and his whānau," Rennie said.

Rennie has also unveiled a 6-2 bench split for the first time, loading the replacements with forwards in a tactic popularised by South Africa. Leicester Fainga'anuku, a centre or wing by trade, is named as a loose forward after impressing in that role for Toulon and the Crusaders.

"There's a lot of trust in the people we've selected in this group. So, a couple of people will get opportunities, and they've deserved them. If they perform, it raises the bar on that position, and then the other person to get back in's got to raise his game – it's just a flow-on effect really," senior coach Neil Barnes said.

The experiment comes against a Wales side ranked 10th in the world, eight places below New Zealand, and still rebuilding under Steve Tandy. Rennie acknowledged the breakdown remains a Welsh strength, prompting the retention of Scott Barrett and Peter Lakai in the starting back row alongside Segner.

The match offers a platform for several players to press World Cup claims. Segner faces a stern test against Taine Basham, Jac Morgan and James Botham, while half-backs Cortez Ratima and Kyle Preston continue their battle for the backup scrum-half role behind Cam Roigard.

Mo'unga seeks to answer critics after two unconvincing outings on the Rugby's Greatest Rivalry tour, and midfielder Anton Lienert-Brown aims to silence doubts about his inclusion. Hooker George Bell, props Xavier Numia and Pasilio Tosi, lock Jamie Hannah and loose forward Ethan Blackadder all have points to prove from the bench.

Wing Fineanganofo benefits from Will Jordan's absence through injury, while the 6-2 split means utility back Rieko Ioane covers both midfield and outside backs. Josh Moorby, the other starting wing, can also slot in at full-back if required.

Among the notable omissions, Josh Jacomb misses out despite strong form against South African URC teams, and Timoci Tavatavanawai is overlooked entirely. Prop Saula Ma'u and fly-half Chay Fihaki also fall victim to the bench configuration.

New Zealand have not lost to Wales since 1953 and a defeat in Cardiff would be a major upset. The match kicks off on Saturday at the Principality Stadium, with both teams looking to build momentum in the Nations Championship.
