Wing wizard Jona Nareki ran in a hat-trick as the Highlanders recovered from a 14-point deficit to sink the Chiefs 39-23 in Hamilton.

The result meant the Chiefs lost a 10th successive game, and they will scarcely have better opportunities to get back to winning ways in Super Rugby Aotearoa, having led 20-6 inside half an hour of this contest.

Yellow cards for Sio Tomkinson and Ash Dixon hindered the Highlanders early on, and tries from Luke Jacobson and Damian McKenzie put the Chiefs apparently in charge.

Nareki had other ideas, though, and when the 23-year-old sprinted 90 metres from deep inside his own 22 to score, it was an ominous warning of what was to come.

Folau Fakatava cut further into the narrowing deficit 10 minutes into the second half, darting over from close range, and then Nareki took over, firstly with a lung-busting dash through midfield that ended with him feeding Shannon Frizell to power over the line.

Nareki himself raced over in the right corner for his second try in the 57th minute, showing great pace but also the nimblest of footwork to scythe through the Chiefs defence.

He got in again in the 69th minute, this time on the left, beating a desperate last-ditch attempted tackle to dot down in the corner and complete the hat-trick.

Josh Ioane added the extras to four of the Highlanders' five tries and added a pair of penalties, with the Chiefs left wounded by a brutal setback.

Kieran Hardy has been released from the Wales squad after suffering a hamstring problem and Dan Biggar is also nursing an injury following the Six Nations victory over England last weekend.

The scrum-half scored a try in the leaders' 40-24 win at the Principality Stadium on Saturday, but also sustained an injury.

Hardy has returned to the Scarlets to continue his rehabilitation, with a weekend off to come before a trip to face bottom side Italy at Stadio Olimpico a week on Saturday.

Wales attack coach Stephen Jones said: "It's unfortunate [for Hardy] after having a wonderful performance against England.

"We've got three scrum-halves left who are good to go."

 Jones also confirmed fly-half Biggar is carrying an injury, but is "very optimistic" he can face the Azzurri.

Aaron Wainwright and Owen Watkin have been released to play for the Dragons and the Ospreys respectively this weekend. The duo will return to link up with the national team after featuring for their regions.

Wales wrapped up the Triple Crown with a defeat of the defending champions and lead France, who have a game in hand against Scotland, by five points.

France and Wales are set to do battle at Stade de France on March 20.

World Rugby has declared this year's Rugby World Cup in New Zealand should be postponed to 2022, dealing a major blow to the women's game.

Citing "uncertain and challenging" conditions caused by the coronavirus pandemic, World Rugby said it would not be possible to suitably stage an event of such scale.

Its recommendation will be put to the Rugby World Cup board and World Rugby's executive committee on March 8 and 9 but seems certain to be passed.

In a statement, the governing body said: "World Rugby has made the difficult decision to recommend the postponement of Rugby World Cup 2021, scheduled to be hosted in New Zealand from September 18 to October 16, until next year.

"While appreciating the recommendation is extremely disappointing for teams and fans, it has their interests at heart, and gives the tournament the best opportunity to be all it can be for them, all New Zealanders and the global rugby family."

It is clear World Rugby has made the recommendation to stave off the possibility of the tournament going ahead in difficult, sterile conditions.

New Zealand as a nation has achieved low instances of COVID-19, in a large part because of strict border controls.

World Rugby said: "It has become clear in recent discussions with key partners including New Zealand Rugby, the New Zealand government and participating unions, that, given the scale of the event and the COVID-19-related uncertainties, it is just not possible to deliver the environment for all teams to be the best that they can be on the sport’s greatest stage.

"The challenges include uncertainty and the ability for teams to prepare adequately for a Rugby World Cup tournament both before and on arrival in New Zealand, and challenging global travel restrictions."

Ireland hosted the last Rugby World Cup for women in 2017, with New Zealand beating England in the final, giving the Black Ferns a fifth victory in the last six editions of the tournament.

Johnny Sexton will continue to strut his stuff for Ireland and Leinster after signing a one-year contract extension to the end of the 2021-22 season.

The 35-year-old laid to rest speculation over his immediate future as he agreed a longer deal with the Irish Rugby Football Union (IRFU) on Tuesday.

Sexton, the 2018 World Player of the Year, is Ireland's captain and talisman, with the fly-half in no rush to hang up his boots. 

"I am really enjoying my rugby and I want to keep learning and adding value to both the Ireland and Leinster environments," he said. 

"I am enjoying the challenge of captaincy and the added responsibility that it brings. My appetite for success is the same as it ever was and the ambitions of both the Ireland and Leinster squads match my own."

Sexton's impressive list of honours includes three Six Nations titles with his country, for whom he was won 97 caps, and four European Cups with Leinster. 

Ireland's 2021 Six Nations campaign started with back-to-back loss against Wales and France before Saturday's thrashing of Italy.

All Blacks half-back Aaron Smith has committed to New Zealand Rugby (NZR) until the 2023 World Cup in France after signing a new contract.

NZR confirmed on Tuesday that the 32-year-old, who has 97 caps for the All Blacks, had penned a new deal securing his future with Super Rugby side Highlanders and provincially with Manawatu.

Palmerston North-born Smith is New Zealand's most capped half-back and remains a key member of the All Blacks side who finished third at the 2019 World Cup.

"One thing that hasn't changed is my love for the Highlanders, the All Blacks and Manawatu," Smith said.

"The decision to stay is based on a number of things, but I'm very keen to see the Highlanders do well, we have a good environment here and some great, young players, so I think the next few years will be exciting for us and it'll be great to be part of it.

"Dunedin has been good to me. My wife Teagan and I have a home and a business here and our son Luka was born here. 

"I felt that committing to the Highlanders for another few years in some small way says thanks for all the support we have enjoyed over the years."

All Blacks coach Ian Foster added that Smith's influence on the side could not be underestimated.

"He is so instrumental in the way we play the game and is such a vital cog for us, both on and off the field, so this is fantastic news," Foster said. 

"We're delighted that Aaron, Teagan and his family have decided to commit to New Zealand and congratulate them on the decision."

It is anticipated Smith will bring up his 100th New Zealand cap this year, while he is two caps away from equalling the record for most appearances for the Highlanders.

Maro Itoje gave away five penalties in England's 40-24 Six Nations defeat to Wales but head coach Eddie Jones claimed officials can "tend to over-referee a player like him".

Referee Pascal Gauzere faced scrutiny over his decision-making in Saturday's Cardiff clash, a third-round tussle in the Six Nations.

Wales scored two controversial first-half tries, but England's lack of discipline was also the Red Rose's undoing, giving away 14 penalties in total.

Jones related the attention Itoje draws from match officials to that experienced by former Australia forward George Smith.

Speaking about Saracens star Itoje, Jones said: "He is one of the best players in the world and he plays the game on the edge.

"I can remember the same sort of discussion being had about George Smith at one stage. Sometimes the referees tend to over-referee a player like him."

Quoted in several newspapers, Jones said Itoje could find ways to improve, for the benefit of his teams.

"There are areas of the game he needs to tidy up and he knows that," Jones said. "He's a good boy. A good player. There are just a few things in his game he needs to tidy up."

Jones would not want a repeat in England's next scheduled match, the home clash with coronavirus-hit France on March 13.

The apparent depths to which sporting rivalries can sink was underlined on Sunday when England prop Ellis Genge revealed he had received death threats after the Principality Stadium defeat.

Genge was shown on camera not clapping off the Wales team at the end of the match.

Genge wrote on Twitter: "Don't know why I'm not clapping in that tunnel must be deep in thought, utmost respect for the Welsh. As for keyboard warriors sending death threats etc ...."

England Rugby denounced such social media targeting of players, stating: "Respect is a core value of rugby. Yesterday we lost to Wales who deserved their victory.

"Unfortunately some of the reaction on social media to players and the team has not shown the level of respect the rugby community prides itself on.

"We will support our players and team against online abuse and hope true rugby fans will stand with us."

Eddie Jones and Owen Farrell refused to point the finger at referee Pascal Gauzere after clinical Wales beat England 40-24 to secure the Triple Crown.

The Red Rose's hopes of retaining the Six Nations title are all-but over after Wales scored four tries in a bonus-point victory at the Principality Stadium on Saturday.

England were made to pay for indiscipline as Wales moved two wins away from a Grand Slam in Cardiff, but the defending champions had every right to feel aggrieved by two controversial first-half tries.

Josh Adams touched down in the corner when he was picked out by a kick from Dan Biggar soon after Gauzere had called time out, having instructed captain Farrell to warn his team-mates about giving away too many penalties.

Farrell confronted Gauzere after he allowed that try to stand and both players were stunned when Liam Williams was awarded a score following a knock-on from Louis Rees-Zammit.

Jones said ahead the match that Gauzere would be under pressure to make the right decisions and the England head coach has previous with the French official, who he complained about to World Rugby in 2018.

The Australian would not say whether he would speak to the governing body again after tries from Anthony Watson and Ben Youngs, as well as 14 points for Farrell, were in vain.

Jones told BBC Sport: "It is what it is. We can't argue with the referee, the result is there in stone, we've got to accept it. Maybe they were tough calls but we weren't good enough to overcome that.

"I'm not going to make a comment on it, I accept the referee's decision. It could have been tough, but we've got to handle it. That’s the decision. It’s 40-24, let’s accept that we weren’t good enough on the day.

"We might have had some though calls. We’ve got to adapt to the game, adapt to the referee. If the referee is going to referee like that, we’ve got to deal with it."

Asked if he might make another complaint over Gauzere, he said: "That's not something to discuss today. Wales were worthy winners.

"I was pleased with how our players fought back, got ourselves back to 24-24 and probably the last play summed up our day.

"We did some lovely attacking work, get to the last pass, they intercepted and go down and score at the other end. That’s the difference of the game."

Skipper Farrell was also not prepared to blame Gauzere.

Asked about the referee's performance, he said: "That's not for us to talk about. We got our way back into it and didn't quite finish it off. There’s plenty that we can do better.

"I'd have to look back at it [the first Wales try]. I don’t know [if we could have been more alert]. There's no point in talking about it now, let everybody else talk about it. We’ll focus on what we can control. We’ll control what we can control."

Wayne Pivac shrugged off the suggestion Wales had luck on their side as they overcame England 40-24 to wrap up a Six Nations triple crown.

Wales have now beaten Ireland, Scotland and England across their opening three matches to take a five-point lead at the top of the standings, though second-placed France have a game in hand.

Saturday's victory was not without its contentious moments, however, as the calls of referee Pascal Gauzere took centre stage in the first half.

First, the French official allowed Josh Adams' opening try to stand, despite having given England little time to set themselves from a Wales penalty, with the referee having asked Owen Farrell to speak to his team.

Gauzere then made the on-field decision to award Liam Williams' try, with TMO unable to definitively prove that Louis Rees-Zammit had knocked on in the build-up.

Wales benefitted from a red card in their wins over Ireland and Scotland, but Pivac put the victory against England in Cardiff down to his team's application.

"Some people are going to say that, they'll say it's been on our side for the last three matches, but you've got to be in games to win them," Pivac told BBC Sport.

"England put a lot of pressure on us and came back, each time we hit them they came back again, so it was a hell of a game and a lot of resilience shown from our boys."

Asked if he had any sympathy for England, Pivac added: "I think when you give away that many penalties – one player giving away five penalties – I think you’re lucky not to concede a yellow card to be honest. I suppose you could argue either way."

Wales lost four of their five games in last season's Six Nations campaign, finishing fifth above winless Italy, yet now look on course for a Grand Slam.

"Time. A bit of time," was Pivac's explanation when asked how his team have turned their fortunes around.

"We've picked a squad to get results in this tournament and we had a good look at some players in the last tournament that we've well and truly documented, but certainly time together and I think you can see there's a good bond growing in this group.

"They enjoy winning things, as they did under Warren [Gatland]. Hopefully we can press on."

As ruthless Wales celebrated winning the Triple Crown, Eddie Jones might have been regretting saying the pressure would be on referee Pascal Gauzere in Cardiff.

Wales head coach Wayne Pivac endured a difficult start to his reign after succeeding Warren Gatland, but his side are two victories from a Grand Slam after beating the defending champions 40-24.

England, on the other hand, saw the Six Nations title all-but slip through their fingers as they were left to rue poor discipline and two controversial first-half tries for Wales.

Red Rose boss Jones has previous with Gauzere and spoke to World Rugby about an incident involving the French official during Wales' win over Scotland in 2018.

The Australian was his usually outspoken self ahead of Saturday's clash at the Principality Stadium.

He said: "Unfortunately, there are no fans but the intensity of the clash I think over the last four or five years, the games I have been involved in, the points difference is six points. They always go down to the wire, so the pressure is going to be on the referee to make the right decisions."

So when Gauzere twice took centre stage in the first half by awarding tries for Josh Adams and Liam Williams, Jones may have been thinking he had made the wrong decision by putting the spotlight on the referee.

Jones should also be pointing the finger at his players, who he said had become more "street-smart" than they were when losing to Wales at the same stadium two years ago.

They were their own worst enemies, conceding 14 penalties as they lost for the second time in three matches, but Gauzere left them up against it and resurgent Wales took full advantage.

Owen Farrell has come in for criticism for having too much to say to referees, but he was understandably aggrieved when Adams was awarded an opening try 16 minutes in.

Gauzere had called time out after instructing the skipper to warn his team-mates about their indiscipline, only to give Dan Biggar the green light to pick out Adams with a pinpoint cross-field kick soon after with the majority of Red Rose caught out in a huddle.

Farrell exchanged words with Gauzere before reducing the deficit to 10-6 with his second penalty, yet the French official took centre stage once again when he raised his arm to signal a try for Williams with half an hour on the clock.

Louis Rees-Zammit was shaking his head in frustration after knocking the ball forward prior to Williams dotting down, but Gauzere opted against changing his decision after consulting the TMO as the ball struck the wing's leg prior to hitting the ground after he knocked it forward.

Rees-Zammit raised eyebrows over the verdict and England responded with a well-finished try from Anthony Watson before Farrell made it 17-14 just before the break.

Kieran Hardy caught England napping early in the second half with a sharp turn of foot to score a third Wales try but Farrell made it a seven-point game when he was on target with the boot again.

England were showing the sort of inventive play they were so badly lacking in the defeat to Scotland and the quick-thinking Ben Youngs nipped in for a superb try, which Farrell converted to level at 24-24 with 17 minutes to go.

The Red Rose continued to give away far too many penalties, though, and Callum Sheedy punished them on three occasion to put Pivac's men 33-24 up with six minutes remaining.

Cory Hill put the icing on the cake as it was Wales who proved to be more "street-smart”, with Pivac celebrating gleefully as his side took a big stride on the road towards another title.

England fell foul of some contentious refereeing decisions and indiscipline as Wales clinched a Six Nations triple crown with a 40-24 bonus-point win in Cardiff.

Eddie Jones' team felt hard done by in the first half with referee Pascal Gauzere at the centre of the discussion, allowing questionable tries from Josh Adams and Liam Williams to stand.

Anthony Watson's try handed England some momentum heading into the second half, though Kieran Hardy's effort seemed to have put Wales back in control.

Owen Farrell moved onto 1000 points in international rugby either side of Ben Youngs' score to level proceedings, yet a trio of composed penalties from Callum Sheedy and a late Cory Hill try settled a topsy-turvy contest.

Biggar kicked Wales ahead in the fifth minute, though Williams just denied Mario Itoje an opening try after a charge down at the other end.

Farrell restored parity after Ben Youngs' break resulted in an England penalty, but the visiting captain was soon left seething with referee Gauzere soon after.

England were given little time to set from a penalty restart, and Biggar's kick found Adams, who raced over in the corner.

Farrell channelled his frustration as he slotted a long-range penalty between the posts, though another contentious call then went against the Red Rose as Williams went over.

Louis Rees-Zammit's fumble in the build-up was adjudged to have gone backwards, and Biggar's conversion clipped the post on its way through.

England hit back when Watson forced himself through a crowd of defenders, and though Farrell missed the kick, he atoned with a penalty on the stroke of half-time.

Hardy cruised through a gap to restore Wales' cushion, though Farrell's penalty pulled England to within seven points – the skipper then reached his milestone 1000 international points by converting Youngs' try.

But with the scores level, defensive errors cost England, and in the space of eight minutes, Sheedy had struck nine points.

It set the stage for Hill to add further gloss as he bundled over under the sticks to send Wales to the top of the standings in style.

Wales looking good in Wayne's world

It was a tough 2020 for Wayne Pivac, but the New Zealander now has his team playing with real confidence and belief.

England might point to the refereeing decisions going against them, but their own errors in the final stages ultimately proved decisive and Wales took full advantage. They now top the standings by two points, with France not playing this weekend due to a COVID-19 outbreak in their camp, and having wrapped up a triple crown, look well on course for a Grand Slam.

Farrell's landmark proves fruitless

It is now 1000 points from 91 caps for England captain Farrell, who appeared to be leading his side back into the contest until those costly defensive slip ups.

Farrell is just the second man to reach that tally for England after World Cup 2003 hero Jonny Wilkinson (1179).

What's next?

England face another huge test in the form of France in round four, while Wales travel to Rome to face lowly Italy.

Johnny Sexton says Ireland are "on a journey" and praised the team's character to bounce back from consecutive Six Nations defeats to hammer Italy in Rome.

Andy Farrell's side had started the tournament with defeats to Wales and France, the first by five points and the second by only two.

Ireland outclassed a poor Italy side on Saturday, though, with the Azzurri now having lost 30 straight Six Nations matches following the 48-10 reverse – the longest losing streak in the competition's history. 

The visitors ran in six tries while Sexton, returning to the side from a head injury, was eight from eight from the tee. That represents the most by any Ireland player while maintaining a 100 per cent success rate from the tee since Paddy Jackson kicked nine of nine against Italy in 2017.

With games against Scotland and England to come, Sexton is keen to ensure Ireland build on a promising display.

"We need to keep our performance levels like that against two very good sides," Sexton told ITV Sport after his 50th Six Nations appearance.

"Scotland have been very impressive in the first two rounds and if not for a red card would have been top of the table, probably. 

"This group is on a journey together, we're a year into it and we'd have liked to have had that performance earlier. 

"It's not for the want of trying, it's just little mix-ups along the way. Thankfully we put them right.

"We played very well, all of our forwards did – they've been very impressive over the first two rounds. 

"We've felt as a team that us backs have let them down at times. We improved on a lot of those areas today and thankfully got the victory we were desperate for. 

"We spoke about how close we were in the first two – both very different games but just very proud of the boys, the way we bounced back, it's a real sign of character when things have been going the way they have in the last few weeks, just to stick together and to show the work we've been doing behind the scenes."

Ireland have now won 21 of their 22 games against Italy in the Six Nations, while the 38-point margin of victory was their biggest in any Test match since beating the same opposition 63-10 in February 2017.

Ireland kick-started their Six Nations campaign as they beat Italy for an eighth successive time in the competition, claiming a 48-10 bonus-point victory in Rome.

Having gone down to Wales and France in their opening matches – the first time Ireland had lost their first two games of a Six Nations campaign – Andy Farrell's men got their first win of the 2021 campaign on Saturday.

The returning Johnny Sexton was typically influential, on point with his kicking and integral to slick attacks as Ireland made it 21 wins from their last 22 Six Nations meetings with Italy.

Garry Ringrose, Hugo Keenan and Will Connors propelled Ireland to a 27-point haul in the first half, Ireland's best first-half total in a Test since February 2018, with CJ Stander and Keith Earls also getting in on the act to seal a routine triumph.

Welcomed back into Ireland's line-up after missing the defeat to France due to a head injury, Sexton marked his 50th Six Nations appearance with a simple three-pointer five minutes in, moments after Paolo Garbisi nosed Italy ahead.

Sexton was adding two more points to his tally five minutes later, with Ringrose having picked a gap in Italy's defence to score the game's first try.

Another Sexton penalty edged Ireland further in front and despite some spirited Italy attacking, the visitors struck again as Ringrose turned provider for Keenan.

Ireland had a third try before half-time, Sexton combining with Jordan Larmour to feed Connors in the corner, though Italy managed to strike back through Johan Meyer.

Yet Italy's work was undone by sloppy defending immediately after the restart – Stander bundling his way over.

Italy's issues were compounded before the hour, substitute Giosue Zilocchi sent to the bin for an attempted ball steal.

Ireland appeared to have made their advantage count when Stander found the line again, only for the try to be disallowed for a knock-on.

Luca Bigi's booking handed Ireland a further boost, though, and Connors hauled himself over from a maul before Earls piled further misery on sorry Italy.

Perfect comeback for Sexton

Since his Six Nations debut, Sexton has missed just seven of a possible 57 matches in the championship, including Ireland's defeat to Italy in 2013.

Sexton successfully converted all eight of his kicks on Saturday, tallying up 18 points in total to give him a pristine record. The pace of the game was ideal for the 35-year-old, who also made eight tackles and 20 passes – the last of which played in Earls late on.

More misery for whipping boys Italy

Italy's losing run in the Six Nations now sits at 30 games, the longest of any side in the competition's history. Their last win at home was back in 2013, against Ireland (22-15).

They have now conceded a try-scoring bonus point in 18 of their 22 matches since such add-ons were introduced to the Six Nations in 2017.

What's next?

Italy welcome Wales to the Stadio Olimpico on March 13, with Ireland facing Scotland in Edinburgh a day later.

Mackenzie Hansen crossed for a hat-trick as the Brumbies ran in nine tries to thrash the Waratahs 61-10 in a lopsided Super Rugby AU clash at GIO Stadium in Canberra. 

The hosts made it 17 wins in 18 games at home, scoring 35 points without reply in the second half of proceedings. 

Waratahs actually opened the scoring through a Will Harrison penalty, yet Rob Valetini, Hansen, Noah Lolesio and Connal McInerney all grabbed tries to make it 26-10 to the hosts at the interval. 

Harry Johnson-Holmes had gone over for a score after 30 minutes that Harrison also converted, yet the overwhelmed Waratahs were ripped apart after the break. 

Wing Hansen crossed again in the 56th minute before completing his treble with nine minutes remaining. There were also tries for Nic White, Lachlan Lonergan and Tom Banks, while Lolesio kicked five conversions to give the fly-half a personal haul of 15 points. 

Replacement Ryan Lonergan took over kicking duties to land three conversion attempts following his introduction, helping the Brumbies claim their biggest ever win over their domestic rivals. It is also their biggest margin of victory in a Super Rugby fixture over a fellow Australian team.

The Blues started their Super Rugby Aotearoa season with a 31-16 win over the Hurricanes on Saturday.

Last year's runners-up, the Blues scored three second-half tries at Sky Stadium in Wellington to record an impressive win.

The Hurricanes led at half-time but were outscored 24-5 in the second half.

The Blues were gifted an early try when Devan Flanders threw a loose pass, allowing Dalton Papalii to intercept and score.

But the Hurricanes responded almost immediately through Asafo Aumua, who crashed over in the fifth minute.

A pair of late Jordie Barrett penalties saw the Hurricanes lead 11-7 at the break, but the Blues quickly responded after the interval.

Otere Black's great kick found Caleb Clarke in the corner down the left before Stephen Perofeta also scored to put the Blues up 21-11.

Aumua went over again for the Hurricanes, but the Blues sealed their win through Rieko Ioane with four minutes remaining.

Alex Mafi pounced for two second-half tries as the 14-man Reds snatched a dramatic 23-21 win over the Rebels in Super Rugby AU.

The hooker scored either side of team-mate Feao Fotuaika being sent off, while captain James O'Connor added the extras to both tries and booted three penalties.

Mafi's second try came in the 77th minute, but there was still almost a late twist when the Rebels were handed a last-gasp penalty, only for Matt Toomua to steer his kick left of the posts.

Toomua booted four first-half penalties to two from O'Connor as the Rebels took a 12-6 lead into the break, both fly-halves also missing a kick at goal.

Toomua kicked the Rebels further ahead at the start of the second half, but the Reds responded as Mafi ducked in to find a way to the line from the back of a driving maul.

O'Connor's conversion made it a two-point game, although Reece Hodge then kicked a penalty to give the Rebels more breathing space.

Fotuaika was sent off in the 57th minute for cleaning out Richard Hardwick with direct contact to the head.

O'Connor and Toomua traded penalties before former Melbourne Storm star Suliasi Vunivalu looked to have made a sensational entrance on his union debut for the Reds, the code-switching Fijian sprinting to chase what looked a lost cause.

He wanted a try, but video replays showed Joe Powell had nudged the ball dead before Vunivalu reached it.

Mafi, though, would not be denied. He sold a dummy and sliced through a group of white shirts to dive over and level the game.

O'Connor put the 14 men in front by adding the extras, before the Rebels had their one last shot at goal, Toomua off target from long range.
