Aaron Smith says Antoine Dupont is "on another level" to any other player in the world as the mercurial scrum-half strives to end France's Six Nations title drought.

Dupont tormented Italy in the first match of the tournament, proving four assists – equalling compatriot Frederic Michalak's record for a single Six Nations match – and scoring a try of his own in a 50-10 rout at Stadio Olimpico on Saturday.

The playmaker became the seventh man to lay on three or more tries in a game in the competition, also joining Michalak and former number nine Austin Healey as the only players to have been directly involved in five tries in a match in this tournament. 

Dupont was a constant menace to the Azzurri as he pulled the strings in a livewire display before he was given the chance to put his feet up just before the hour mark.

New Zealand scrum-half Smith, who has earned 97 caps and won the Rugby World Cup in 2015, rates the 24-year-old Toulouse pivot as being a cut above any other player on the planet.

Responding to a tweet from the Six Nations official account asking who is the best player in the world, Smith posted: "@Dupont9A this guy is on another level!

"No one is near him atm. He's the point of difference for both his club and country. He's helping me look at parts of my game to improve. #Respect #9Gang"

Ireland will have to keep Dupont quiet at the Aviva Stadium on Sunday when they look to get up and running following a 21-16 defeat to Wales in Cardiff.

Graeme Smith has admitted Cricket South Africa (CSA) was left "extremely disappointed" with the decision taken by Australia to pull out of their upcoming tour.

A three-Test series was scheduled to take place in March, but Cricket Australia (CA) announced on Tuesday that those plans had been shelved due to the public health situation in South Africa amid the ongoing coronavirus pandemic.

The country was dealing with over 10,000 positive COVID-19 cases a day at the start of January and while that number has since dropped considerably, there is also a new variant of the virus.

However, having done all possible to appease safety concerns and establish protocols so the tour could take place as planned, CSA director of cricket Smith revealed the frustration at the late cancellation.

"We are extremely disappointed by the decision of CA," former Proteas captain Smith said. "CSA has been working tirelessly in recent weeks to ensure that we meet every single expectation of CA.

"This was set to be the longest tour in a BSE (bio-secure environment) comprising a three-match Test series that was scheduled to begin with Australia's arrival later in the month. So to be informed about the CA decision at the eleventh hour is frustrating."

Dr Shuaib Manjra, chief medical officer for CSA, explained how the organisation had done everything possible during the planning stage, including proposing protocols to their Australian counterparts that were "unprecedented".

The cancellation has ramifications for the inaugural ICC World Test Championship, too. New Zealand are now certain to be playing in the final later this year, where they will go up against either England, India or Australia.

Pholetsi Moseki, acting CEO for CSA, said: "It is indeed sad that after all the engagements and effort made to ensure a secure visit by our Australian counterparts, the tour has been derailed.

"CSA has incurred significant costs related to the planning stages and the cancellation of the tour represents a serious financial loss."

South Africa are currently on tour in Pakistan, with the second of two Tests set to start on Thursday in Rawalpindi.

They will also play a three-match Twenty20 series against their hosts - with all the white-ball fixtures to be staged in Lahore - before returning home in the middle of February.

New Zealand Warriors captain Roger Tuivasa-Sheck will switch codes at the end of the 2021 NRL season with the aim of playing for the All Blacks in the Rugby World Cup.

Talismanic full-back Tuivasa-Sheck, 27, has been granted an early release from his Warriors contract to try and force his way into the New Zealand squad for the 2023 showpiece in France.

The 2018 Dally M Player of the Year and two-time Dally M Fullback of the Year expressed gratitude to the Warriors for allowing him to move to the 15-man format.

"This will be my last year with the club and yes, I will be moving to NZ rugby next year," Tuivasa-Sheck said during a press conference on Saturday.

"The club has been supportive in the request and giving me the option to explore.

"Rugby [union] has been the game I've grown up playing. It's always been there in the background. It's always been there, it's no secret. 

"To do it now in a time like this and have the club's support, that's why I chose it now. But rugby is down the line and all that stuff will happen later in the year.

"2021 is my focus, I'm excited about this year and so should the Warriors and NRL fans be.

"There's still a lot of goals I'm chasing [in league] and that's what I'm trying to do this year with the club. We've got a great group here and coaching staff to do something special this year."

Kane Williamson reflected on a "special moment" but insists New Zealand will continue to work hard to improve after reaching the summit of the Test world rankings.

The Black Caps wrapped up victory over Pakistan by an innings and 176 runs on day four at Hagley Oval on Wednesday to seal a 2-0 series win and become the top-ranked Test nation for the first time.

Kyle Jamieson took 6-48 and had 11 wickets in the game to take the Man of the Match award as Pakistan were bowled out for 186 in their second innings.

New Zealand have now won six straight Tests for the first time and swept three consecutive home series', but captain Williamson still wants to see his side kick on.

"It's hard to beat really, I don't know how the rankings work exactly I know they span over a period of time, to achieve that standing means there's been a lot of hard work over a lot of matches, and trainings and all these sort of things to reach that, so it's very special moment from the guys," he said. 

"It's hard to talk about until the Test summer was over, so it's nice to sit back and perhaps take a moment and enjoy the moment.

"I sort of mentioned before in the after match [presentation] that the game is truly a game of small margins. 

"As a side we're pleased with the efforts that went into these last two games but we know the quality side Pakistan have and there were definitely moments in both games that went our way or perhaps moments that we seized and went a long way to putting the result in our favour. 

"It's a game of small margins, guys respect that and it's about working harder and harder to move forward as a collective. 

"We know our next matches will be overseas tours, and just constant adjustments, tinkering to try and perform well in those matches."

For Jamieson, it has been a superb start to Test cricket and he now has four five-fors in six Tests.

"He's a special talent but his attitude, the way he's come in and try to add to the group on or off the field is the most impressive thing. In many ways he's leading and that's great," Williamson added.

"Cricket is an interesting game and something Kyle is extremely good at with bat and ball, a very, very special talent. 

"I think if he continues to, and I'm sure he will he's got great head on his shoulders, bring that great attitude he has - things have come very thick and fast for Kyle and that's a really enjoyable part to the game, something he's learning about and learning about himself.

"But he has a strong desire to improve and pick the brains of the senior guys who have been around a long time. He's a humble guy who wants to get better, I've no doubt he will."

Kyle Jamieson inspired New Zealand to a comprehensive win over Pakistan in the second Test in Christchurch.

Jamieson took 6-48 in the second innings, and 11 wickets for the match, as the Black Caps wrapped up victory by an innings and 176 runs on day four at Hagley Oval on Wednesday.

Pakistan were dismissed for 186 as New Zealand won a sixth straight Test for the first time in their history and secured a 2-0 series success, going top of the world rankings for the first time.

Azhar Ali (37) and Zafar Gohar (37) provided the most resistance as the tourists had no answers to Jamieson and Trent Boult (3-43).

Only Richard Hadlee (15 against Australia in 1985) and Daniel Vettori (12, twice) have taken more wickets in a single Test for New Zealand than Jamieson's 11.

Pakistan resumed at 8-1, still trailing by 354 runs, before Mohammad Abbas (3) fell early after edging Boult behind to BJ Watling, and wasting a review.

Substitute fielder Will Young then took a spectacular one-handed catch diving to his right at point to remove Abid Ali (26) off Jamieson.

Haris Sohail (15) and Azhar edged Jamieson behind to leave Pakistan at 88-5 and the Black Caps well on track for victory.

Mohammad Rizwan (10), Fawad Alam (16) and Faheem Ashraf (28) provided limited resistance before Gohar's late hitting, with Kane Williamson – who made a double century on Tuesday – chipping in with a wicket.

Kane Williamson and a hobbling Henry Nicholls put on a batting masterclass as New Zealand tightened their grip on the second Test against Pakistan.

The pair delivered an almost faultless 369-run fourth-wicket partnership, the third highest for any wicket in Black Caps Test history, as the hosts finished day three with a lead of 354 runs.

After New Zealand had declared on 659-6, the tourists were sent in to face 11 overs and the in-form Kyle Jamieson removed Shan Masood as Pakistan closed day three on 8-1.

Williamson had earlier posted another two blistering sessions to score a brilliant 238 and become the quickest of three New Zealanders to score 7,000 career Test runs.

The world’s top-ranked Test batsman notched his fourth Test double century and was supported by a gutsy 157 from Nicholls, who was hampered by a calf strain while bringing up his third Test 150.

Nicholls pushed through the pain barrier on his home ground at Hagley Oval to join Brendon McCullum as the only players with two Test hundreds in Christchurch.

Daryl Mitchell raced to his first Test century before the declaration, scoring 102 not out, as New Zealand recorded their fifth highest all-time Test total.

Starting the day 11 runs behind the tourists’ first-innings total, the hosts picked up where they left off yesterday with Nicholls bringing up his century off 213 balls for 315-3.

Limping between the creases, Nicholls dug deep to navigate the new ball and went on the attack, hitting the first six of the innings, as Williamson surged past 7,000 career Test runs.

The Black Caps skipper was once again putting on a clinic, punching his 21st boundary back past Naseem Shah to bring up the 300 partnership from 459 balls.

The 30-year-old continued to rack up the milestones, reaching 150 in 247 balls, and bringing up 400 on the final ball of the session as the hosts headed to lunch 103 runs ahead.

Kane Williamson continued his impressive form to give New Zealand control of the second Test against Pakistan on Monday.

Williamson scored his 24th Test century and second in as many Tests on a strong day two for the Black Caps at Hagley Oval in Christchurch.

The right-hander finished the day unbeaten on 112 as New Zealand reached 286-3, trailing Pakistan by just 11 runs, with Henry Nicholls (89) also not out.

Williamson, who moved top of the ICC rankings for Test batsmen last week, was scratchy early before accelerating.

He needed 105 balls to reach his half-century but just another 35 to bring up his ton.

It came after Pakistan put themselves in a promising position by reducing the hosts, who lead the two-Test series 1-0, to 71-3.

The wickets of Tom Latham (33), Tom Blundell (16) and Ross Taylor (12) had Pakistan on a high, and they should have had Nicholls cheaply.

The left-hander was caught by Mohammad Rizwan on three, but Shaheen Afridi (1-45) overstepped.

Williamson and Nicholls attacked as the day went on and Pakistan had their troubles in the field, the former edging through Shan Masood and Haris Sohail in the slips on 82.

Masood dropped Williamson after the star New Zealander passed his century before Rizwan put down an easy chance off Nicholls – then on 86 – off Shaheen.

Nicholls hurt his calf late in the day but managed to get to stumps alongside Williamson on an excellent day for the Black Caps.

Kyle Jamieson ripped through Pakistan’s batting line-up but their middle order proved defiant as New Zealand edged day one of the second Test.

The 6’8” fast bowler grabbed his third five-wicket haul for 69 runs in his sixth Test appearance as the tourists were bowled out for 297 in Christchurch.

Mohammad Rizwan’s side were reeling at 88-4 at lunch after Kane Williamson put Pakistan into bat and Jamieson recorded figures of three for 26 runs in a devastating first session.

Tim Southee made the breakthrough removing Shan Masood for a duck, before Jamieson claimed Abid Ali for 25, Haris Sohail for one and Fawad Alam for two as Pakistan lost three wickets for 17 runs.

Azhar Ali and Rizwan’s 88-run fifth-wicket partnership helped Pakistan recover from their morning collapse until Jamieson found Rizwan's outside edge and BJ Watling snared his opposing wicketkeeper for 61.

New Zealand will aim to continue their winning streak in the second and final Test against Pakistan, with Kane Williamson's side having the chance to make history in Christchurch.

The home team won the opening game by 101 runs late on the fifth day in Mount Maunganui, finally seeing off spirited resistance from Pakistan's tail with 4.3 overs remaining.

Victory means the Black Caps have now won five Tests on the spin – they have never previously managed six in a row in the format.

There will be at least one change to their team for their first outing in 2021, Neil Wagner ruled out with a broken toe.

The left-arm paceman played on through the pain in the first Test, earning praise from Williamson. However, he is expected to be sidelined for six weeks, leading to New Zealand calling up Matt Henry.

As for Pakistan, they are set to be boosted by the return of captain Babar Azam, who missed the previous game – as well as the Twenty20 series that preceded the Test action – with a broken thumb.

Without their talismanic captain, the tourists were fragile at the top of the order. They fought back well from 52-5 to post 239 in their first innings, while nearly saved the game despite slipping to 37-3 second time around.

They will be up against it, though; New Zealand have lost only one of their previous seven Tests played at Hagley Oval, a seven-wicket defeat to Australia in February 2016.

ON TOP OF THE WORLD

Williamson had a fabulous 2020 in Test cricket, despite the international schedule being badly hampered by the coronavirus pandemic.

The right-hander had the highest average (83) in the format across the previous calendar year out of those players to have had at least four innings, with his knock of 129 in the first Test – combined with Steve Smith's struggles for runs against India – moving him back to the top of the ICC world rankings for Test batsmen.

A career-best score of 251 against West Indies substantially helped his cause. That was his only innings in the series too, as he missed the second Test due to the birth of his first child.

PAKISTAN SET FOR BABAR BOOST

The tourists felt the absence of their captain in the series opener and still almost fought their way to a draw.

Mohammad Rizwan, who was the skipper in the first Test, said Babar was on track for a return, but a decision would have to wait until Sunday.

"He is fine now. He wants to hit some more balls in the nets and we'll decide [on Sunday]," he said, via the New Zealand Herald. "He's a legend and wants to hit some more balls because [on Friday] he batted very well. If he plays, we bat around him. He has a great impact on our team."

Babar, 26, averages 45.44 in 29 Tests for Pakistan, who are aiming to level the series.

KEY OPTA FACTS

- New Zealand will be looking to win a third consecutive multi-game bilateral Test series against Pakistan.
- Pakistan are winless in their past 10 Tests outside their own country (D2, L8). However, their last such victory did come against New Zealand, by an innings and 16 runs (November 2018 in Dubai).
- Tom Latham has scored 579 Test runs at Hagley Oval, 214 more than any other player at the venue and his second most at any ground in the format (696 at Basin Reserve).
- Ross Taylor is 13 away from becoming just the fifth player to score 1,000 runs in Tests between New Zealand and Pakistan. He would be only the second Kiwi to achieve the feat (after Williamson).
- Tim Southee has a bowling average of 19.9 in Tests at Hagley Oval, his best at any home venue. He has picked up five or more wickets in six of his seven appearances at the venue.
