Brodie Retallick has won the vote to start in the second-row for New Zealand in the Rugby World Cup final against South Africa.

Retallick comes in for Sam Whitelock in the only change from the All Blacks side that overpowered Argentina 44-6 in the semi-final last Friday.

Whitelock replaced Retallick against Argentina but now moves to the bench for Saturday’s final at the Stade de France in Paris.

The 35-year-old Whitelock will become the first man to play in three World Cup finals, should he come off the bench.

Tight-head prop Nepo Laulala replaces Fletcher Newell on the All Blacks bench.

Brothers Scott, Jordie and Beauden Barrett all feature in the starting XV, which openside flanker Sam Cane captains.

The All Blacks, like South Africa, are chasing a record fourth title after triumphs in 1987, 2011 and 2015.

New Zealand squandered an 18-point lead before recovering to snatch a dramatic 39-37 victory over Australia as they moved a step closer to winning the Rugby Championship.

The All Blacks led 31-13 in a Bledisloe Cup classic at a packed Marvel Stadium with an hour played, yet they trailed 37-34 with normal time up in Melbourne.

However, Beauden Barrett capped a truly remarkable contest by touching down in the corner with nearly 81 minutes on the clock to break Australian hearts, after a controversial decision that saw the hosts penalised for time-wasting and the visitors handed a scrum in front of the posts.

New Zealand have now won 17 of their past 21 Tests against Australia, including four in a row, and are five points ahead of Argentina and South Africa, who meet on Saturday.

Beauden Barrett is fit to return for New Zealand when they go in search of revenge against Argentina on Saturday.

Barrett missed the Pumas' first-ever away victory over the All Blacks last weekend due to a neck injury, but he is back in contention for the Rugby Championship clash at FMG Stadium Waikato.

The two-time World Rugby Player of the Year said: "I'm feeling really good, sun's on the back, beautiful Hamilton day, and good to get a full training under my belt, too."

He quipped: "I've realised that I've got to get a neck like a front rower to be able to handle these knocks, so I've been working hard on it in the gym with Pete [All Blacks physio Pete Gallagher].

"A few more shoulder-on tackles, and I'd say I'm just about ready to go."

The All Blacks have lost four out of six Tests this year and are third in the Rugby Championship table after their historic loss to Michael Cheika's men in round three.

Barrett says the All Blacks will stick with their principles but are prepared to adapt.

"We don’t want to be like other teams," he added. "We've still got to be the expressive All Blacks that we know we can be.

"When the pressure comes on, we want to run the ball, keep it in hand, it's just what feels so natural to us.

"We've identified that in games that we’ve lost, we may need to kick the ball a little bit more, it seems unnatural, but it's just being aware of that.

"And looking to attack in different ways – everyone on our feet, chasing kicks, getting those 50-50 bounces or flooding rucks and looking for turnovers that way. We are figuring out the way that we want to play."

Beauden Barrett will drop to the bench for New Zealand's tussle with South Africa on Saturday, with Richie Mo'unga brought in at fly-half as one of four changes made by under-pressure All Blacks head coach Ian Foster.

New Zealand fell to a 26-10 defeat to the Springboks in their opening match of the Rugby Championship last weekend, recording three consecutive Test defeats for the first time since a run of five without victory in 1998.

Having also overseen a first home series defeat to Ireland, Foster has come under increasing scrutiny after the All Blacks slumped to an all-time low of fifth in the world rankings.

New Zealand have suffered five defeats in their past six Tests, but Foster vowed to fight on after the defeat to South Africa, and will rely on Mo'unga to provide creativity in Johannesburg.

Barrett was passed fit to play despite being involved in a heavy collision with Kurt-Lee Arendese in the Rugby Championship opener, but Foster has handed Mo'unga his first start of the year at number 10.

New Zealand's other changes come in the forward line, with Props Ethan de Groot and Tyrel Lomax, as well as flanker Shannon Frizell, all introduced.

There has been speculation that a defeat at Ellis Park would end Foster's thee-year tenure, but he remains upbeat.

"Belief and confidence remain high in our group, which is working incredibly hard this week," Foster said. 

"Playing at Ellis Park is always a special occasion for any All Black team, and this weekend will be no different. Adding to that, the Freedom Cup is on the line, which makes this a challenge that everyone is looking forward to."

Mo'unga insists New Zealand are shutting out criticism of their performances.

He said: "They [the supporters] care about our team and care about our results, but it's also fair of us to not care about what they think because we have a role to do, a role to play, and hearing that isn't going to help us at this moment.

"I'm at a stage now if you're not in our squad, I don't really care what you think, with all respect. We're trying our best, and we know it's not good enough for All Blacks standards."

New Zealand team: Jordie Barrett, Will Jordan, Rieko Ioane, David Havili, Caleb Clarke, Richie Mo'unga, Aaron Smith; Ethan de Groot, Samisoni Taukei'aho, Tyrel Lomax, Samuel Whitelock, Scott Barrett, Shanon Frizell, Sam Cane (captain), Ardie Savea.

Replacements: Codie Taylor, George Bower, Fletcher Newell, Tupoi Vaa'I, Akira Ioane, Finlay Christie, Beuden Barrett, Quinn Tupaea.

Beauden Barrett bagged a pair of tries on his 100th Test appearance for New Zealand as the All Blacks swept away Wales 54-16 amid a deluge of late tries in Cardiff.

A week after they thrashed the United States 104-14 in Washington, New Zealand found greater resistance in the Welsh capital, but they eventually took the game away from their hosts, turning a spicy Autumn Nations Series contest into a drubbing.

Barrett took New Zealand beyond 50 points in the 79th minute with his second try of the match, and the visitors' seventh in total.

New Zealand raced into a fourth-minute lead, centurion Barrett intercepting a pass from Gareth Anscombe and charging through to score under the posts.

Try-scorer Barrett was spared a yellow card after a seemingly deliberate knock-on, before Wales lost Alun Wyn Jones to injury on the day the captain beat Richie McCaw's record tally of 148 caps for an international team. Jones suffered the upper-body blow when tackling Jordie Barrett.

New Zealand were well on top and had a second try in the 34th minute when scrum-half TJ Perenara scuttled in from close range. Prop Nepo Laulala was then only yellow-carded after making heavy contact with the head of Ross Moriarty in a tackle, perhaps a let-off for the tourists.

Kicking from Anscombe, Jordie Barrett and Rhys Priestland kept the scoreboard ticking along, before wing Will Jordan produced a thrilling third All Blacks try, chipping ahead and sprinting through to collect and dot down.

Johnny Williams thrilled the home crowd when he threw himself on Priestland's skidding kick behind the All Blacks defence, narrowing the gap to 28-16.

Then came the New Zealand surge, as Dalton Papalii exploited a gap in the Wales defence from a lineout to inflict more punishment, Sevu Reece exchanged passes on the left with Ardie Savea before dashing in, and Anton Lienert-Brown raced to the corner on the opposite flank.

Beauden Barrett had the final say, another interception seeing him gain possession on halfway, reading the pass from Johnny McNicholl and driving to the line.

Barrett times it to perfection

Moments after he was announced to the crowd as man of the match, Barrett turned on the afterburners for a second time. It was a fitting way for his match to end.

He told Amazon Prime it had been a demanding week, given the focus on him.

"I've spent a bit of time reminiscing this week and I've tried not to overdo it because we had a job in hand tonight and I wanted to focus on playing well," Barrett said. "Tonight, I'll enjoy my boys' company and thank all those people who have helped me along the journey."

Joy for Jordan

Jordan's try here was one even the most ardent Wales supporter must have admired. The decision to chip and the execution both smacked of a player with unwavering self-belief. Jordan has now scored 16 tries in Test rugby since his debut for New Zealand, twice as many as any other Tier 1 player in that period.

New Zealand ran in 16 tries in a 102-0 demolition of Tonga.

Will Jordan helped himself to a five-try haul, while scrum-half Brad Weber ran in a hat-trick as the All Blacks reached a century of points for the sixth time in their history.

They are the only country to have achieved the feat more than once and it was the second time Tonga have found themselves on the receiving end.

Damian McKenzie got the scoring underway with a second-minute try and the full-back went on to claim three assists as nine All Blacks crossed overall.

Dalton Papalii's first-half double, along with Jordan and Weber getting into their work meant it was 43-0 at half-time and worse was to follow for the visitors, who were without the bulk of their northern hemisphere players due to COVID-19 travel restrictions and named 13 debutants.

Luke Jacobson, Richie Mo'unga, Rieko Ioane and Patrick Tuipulotu all got in on the act in the second half, marking an emphatic start to their 2021 schedule having won only half of their six 2020 outings.

Mo'unga landed seven conversions before making way for Beauden Barrett, back from his sabbatical in Japan.

Barrett added the extra for a fourth and final time after the hooter when George Bridge compounded Tonga's misery by bringing up three figures – his try a reward for a tireless performance where the wing made seven clean breaks.
