The tourists looked to have given themselves a great chance of going 2-0 up by posting 199-5 at the National Stadium in Karachi on Thursday, but Babar and Rizwan stole the show with a stunning world record stand in a T20I run chase of 203.
Shahnawaz Dahani (2-37) struck twice in as many balls to get rid of Alex Hales (26) and Dawid Malan (0) before Phil Salt fell for 30, with Moeen Ali having won the toss and elected to bat first.
Ben Duckett hit a quickfire 43 and Harry Brook a brisk 31, with stand-in captain Moeen then blasting an unbeaten 55 from only 23 deliveries to set Pakistan 200 to win, Haris Rauf taking 2-30 from his four overs.
Skipper Babar and Rizwan showed their class as they brought up a century stand in just 69 balls, Hales left to rue dropping the wicketkeeper-batter on 23 as he made a third consecutive half-century.
The prolific Babar brought up his hundred in the 18th over and finished unbeaten on 110 from 66 balls in a masterclass, with the in-form Rizwan 88 not out off 51 deliveries as England were left not knowing what had him them.
Babar cleared the rope six five times and hit 11 fours, while Rizwan launched four sixes and five fours as they showed a combination of timing and power.
Babar reaches another milestone in style
The incredible Babar surged past the 8,000-run mark in T20s in his latest masterful knock. He reached that milestone in his 218 innings, with only Chris Gayle (213) needing fewer to rack up 8,000.
He also now holds the record for the most centuries as Pakistan captain with 10 ahead of the great Inzamam-ul-Haq.
Moeen fireworks in vain, Duckett catches the eye
While England were unable to make an impact in the field due to the brilliant of Pakistan's openers, they impressed with the bat.
Moeen hit four sixes and as many fours, while Duckett looked in great touch before he departed when well set, hitting seven boundaries.
Faf du Plessis got 58 as South Africa posted a competitive total of 179-6 after England won the toss and elected to bowl at Newlands on Friday.
A successful run chase was looking unlikely for the tourists by the time they fell to 34-3 in the sixth over, but Bairstow scored 86 not out from just 48 balls in a superb innings.
After dropping down to number four in the order, Bairstow hit nine fours and four sixes, sealing victory with four deliveries to spare with a huge maximum.
Ben Stokes (37) provided good support as England took a big step towards winning a third consecutive T20I series against South Africa, who are playing their first international cricket since March.
The second match is in Paarl on Sunday before the series concludes back in Cape Town next Tuesday.
CAPTAIN AND FORMER SKIPPER SET UP PROTEAS
England made a good start with the Proteas only mustering 12 runs from the first three overs.
But a six from captain Quinton de Kock off Jofra Archer (1-28) sparked 38 runs in just two overs to kick-start the South Africa innings and he went on to build a partnership of 77 with former skipper Du Plessis.
Chris Jordan (1-40) ultimately removed De Kock for 30 and then claimed a catch at deep square leg to end the 40-ball innings of Du Plessis.
But by that point South Africa were 110-3 and a platform had been set for Rassie van der Dussen (37) to keep up the pace.
BAIRSTOW BOOSTS ENGLAND
Stokes made an astonishing Test-best 258 in Cape Town in January 2016 and Bairstow also shone in that game, scoring a maiden Test ton.
The duo impressed again by putting on a crucial 85 partnership, but Bairstow still had plenty to do when Stokes holed out to long on off the bowling of Tabraiz Shamsi (1-27).
After Eoin Morgan (12) made a slow start, England suddenly needed 55 from 25 but Bairstow hit six of his side's eight boundaries from there in an impressive finish.
LINDE AND SAM CURRAN IMPRESS
It was a good T20I debut for South Africa's George Linde, who hit a quickfire 12 from six balls with the bat before taking 2-20, including the early wicket of Jason Roy (0), plus a key catch to remove Stokes.
While Tom Curran (1-55) struggled, Sam was the pick of the England bowlers, with figures of 3-28 from his four overs and the crucial wicket of Du Plessis.
He later hit a six with the bat in the penultimate over to help settle the tourists' nerves after Morgan's dismissal.
Tim Seifert (50) and milestone man Taylor (53) had steered the Black Caps to within sight of a consolation win at Bay Oval before familiar frailties again cost them near the finish line.
Jasprit Bumrah claimed 3-12 from his four overs and Navdeep Saini chipped in with 2-23 to destabilise New Zealand as they tried and failed to chase down 163.
India rested Virat Kohli and will hope Rohit Sharma, who top-scored with 60, quickly recovers from the suspected calf injury that prematurely ended his innings as they look ahead to the forthcoming ODI series.
After stand-in skipper Rohit elected to bat, India initially looked on course to exceed the 165 they set prior to prevailing in a Super Over at Westpac Stadium two days ago.
Sanju Samson squandered the opportunity granted to him in Kohli's absence, the opener driving Scott Kuggeleijn's wide delivery straight to Mitchell Santner at short cover, but his second-over exit failed to prevent the tourists from making a strong start.
Rohit and KL Rahul (45) put on 88 in 10 overs before the latter presented another simple catch to all-rounder Santner, this time from Hamish Bennett's bowling.
Shreyas Iyer made a sedate 31-ball 33 as India struggled to accelerate after Rohit decided he was unable to continue, having received treatment for a muscle problem.
Kuggeleijn removed Shivam Dube for five at the end of the 19th over and, though Tim Southee went for 52 from his allotted overs, the Black Caps appeared to have restricted India to an achievable target.
That especially seemed to be the case during the rapid 99-run partnership between Taylor and Seifert, the pair at one point taking 34 from six Dube deliveries.
But, having lost their nerve in back-to-back Super Over losses in Hamilton and Wellington, New Zealand's habit of throwing away winning positions again became an issue.
Seifert and Daryl Mitchell succumbed to Saini and Bumrah in consecutive overs to force a change in momentum, which completely swung India's way as Santner, Kuggeleijn and Taylor all departed in quick succession.
The Black Caps had lost 5-25 when Bumrah scrambled Southee's stumps to give little meaning to some late Ish Sodhi fireworks at the end of a lopsided series.
Pakistan set England a target of 161, led by opener Shan Masood top-scoring with 39 runs off 22 deliveries, while David Willey impressed with the ball by taking two wickets for England.
England opener Phil Salt was bowled by Naseem Shah for just one run, but a rapid innings from Stokes (36 off 18), coupled with Liam Livingstone's 28, put England in good stead to secure victory by the time of their dismissals.
Brook scored 45 not out from 24 balls and Sam Curran smashed an unbeaten 33 from just 14 to finish the job as England chased down Pakistan's total in just 14.4 overs.
England middle order impresses
With their openers producing a combined 10 runs off 16 balls, it fell on the middle order to win England the match, and they did so in thrilling fashion.
Stokes, Livingstone, Brook and Curran smashed the ball to all areas and accounted for all 12 of their team's sixes.
Each of that quartet finished with strike rates of at least 175 to help England to a morale-boosting victory before their World Cup campaign gets underway against Afghanistan on Saturday.
Jordan improves after tough start
Pakistan ended up on 160-8 from 19 overs, with the match shortened slightly due to a brief rain stoppage.
They had threatened a bigger total, with Chris Jordan smashed for 27 off his first two overs without taking a wicket, but the England bowler steadied the ship to finish with figures of 1-36 from four, including a final over which went for just three runs and included the wicket of Mohammad Wasim (26).
Jordan's bowling at the death ensured England's target was achievable, and they then chased it down comfortably.
Bumrah underwent an operation in New Zealand last month and the procedure was a success.
The Board of Control for Cricket in India (BCCI) revealed paceman Bumrah began his rehabilitation at the National Cricket Academy (NCA) in Bangalore on Friday.
Bumrah has been sidelined since a home T20l series against Australia in September.
Meanwhile, Iyer will undergo surgery on his lower back next week.
The batter will remain in the surgeon's care for a fortnight before returning to the NCA to start his rehabilitation.
Iyer and Bumrah were forced to miss the ongoing Indian Premier League due to their injuries.
Buttler suffered the injury while playing in the Hundred in August and did not take part in England's series win over Pakistan.
But he returns on Sunday against world champions Australia, where they will play three matches ahead of the World Cup.
"I'm back to 100 per cent," Buttler said. "Had a good time in Pakistan rehabbing, probably could have played earlier, but with the World Cup around the corner, it was the right thing to do."
Buttler is expected to open with either Alex Hales or Phil Salt, and he is confident in England's batting capabilities.
"We have great options at the top of the order with guys in really good form in Pakistan," he added.
"They're both excellent options. Whoever I partner with will have a great go at it."
Buttler also revealed that Liam Livingstone is a doubt for the World Cup, starting later this month.
He explained Livingstone is "a little way off at the minute", saying: "Hopefully he'll get back to full fitness before the start of the World Cup."
England are on the brink of a first T20 series victory over India, now leading 2-1 with two matches to play.
In a match played behind closed doors at Ahmedabad's Narendra Modi Stadium due to coronavirus restrictions, the tourists limited India to 156-6 despite a fantastic unbeaten 77 from captain Virat Kohli.
But England had few issues reaching their target, Buttler and Jonny Bairstow (40 not out) finishing things off to move within one win of a series victory. The two sides do battle again at the same venue on Thursday.
After an impressive India run chase to win the second match, England opted to bowl first when they won the toss and chasing once again proved to be the successful strategy.
Jofra Archer (0-32) dropped a return catch offered by Rohit Sharma (15) with his first ball bowled but Mark Wood - the fast bowler in electrifying form to claim 3-31 - bowled KL Rahul for his second straight duck. The opener has one run in his past four T20I innings.
India did not get a boundary until the 21st ball and even then it was a fortuitous inside edge for Rohit.
He soon followed Rahul to the dressing room when Wood struck again in the fifth over, before Chris Jordan (2-35) had Ishan Kishan – man of the match on his debut last time out – caught behind for just nine.
Kohli and Rishabh Pant (25) slowly steadied the ship until the latter was run out and India looked out of contention at 87-5 with five overs to spare.
But Kohli starred to ensure his team at least had a score to defend by the time Hardik Pandya (15) was out from the last ball of the innings.
Jason Roy (9) and Dawid Malan (18) did not get going for England but Buttler was in control of the run chase, his 52-ball knock containing four maximums.
Buttler and Bairstow put on 77 together as England coasted to their target with 10 balls to spare.
Kohli spectacular again
India skipper Kohli scored 73 not out in the second match and he was even better here in another unbeaten innings.
He scored 77 runs from 46 balls with 12 boundaries - eight fours and four sixes.
The hosts scored 69 runs in the final five overs, an astonishing 49 of them going to Kohli in just 17 balls. Only Yuvraj Singh (58) has ever scored more in the last five overs of a T20I for India.
The only negative note for Kohli individually was when he dropped Buttler at point, but by then the result was beyond doubt.
100 up for Morgan
Eoin Morgan became the first England player and just the fourth cricketer to reach 100 T20I appearances.
It was fitting that England won to mark the occasion, though Morgan himself had one of his quieter games having not been required to bat.
The explosive England captain has 113 career sixes, a stat that puts him third overall and only behind Martin Guptill and Rohit in the shortest format.
With Tom Abell and Will Jacks unavailable due to injury, England might have sent for batting reinforcements but instead elected to persevere with their weakened unit.
It meant Moeen Ali batted at three on Sunday, with Sam Curran at six, both bumped up higher than they would usually be expected to figure in the order.
Moeen made 15 and Curran added 12 in a feeble 117 all out, with Buttler dropping down from playing as an opener to bat at number four, where he scored only four.
Bangladesh won by four wickets, with Najmul Hossain Shanto hitting 46no, leaving Buttler to face questions about England's performance, and their selections.
"It's a different balance and it's a different feel to the team," he said. "I think we're wanting to give exposure to guys especially who, in these conditions, will also probably play a part in the 50-over World Cup.
"It felt like a great chance to expose the all-rounders' batting, maybe one spot higher than in our normal team.
"The way cricket is at the moment, there's a few players who've opted not to be here anyway for various reasons. So instead of calling up someone else, we tried to use the guys who would be exposed to these conditions in the 50-over World Cup as well."
Regarding his own move in the line-up, perhaps intended to beef up the middle order, Buttler said: "I'm very comfortable batting anywhere in the order.
"I've spent a hell of a lot of my career as a middle order player, and I think we've got some good options. I just felt like it would be an opportunity to try something different."
England will hope for a better outcome in Tuesday's final match, but Bangladesh's wins in Chattogram and Mirpur mean the tourists are playing for mere consolation.
Dawid Malan's rapid 77 fired the much-improved hosts to 215-7, a huge tally which India looked capable of reaching after the outstanding Suryakumar Yadav scored 117 off just 55 balls.
But Reece Topley (3-22) claimed three wickets as England held off India's chase to record a morale-boosting triumph, their first since Eoin Morgan's international retirement.
Looking to recover from comprehensive back-to-back defeats, Buttler's men produced a far better performance with the bat in Nottingham as their skipper's fourth-over dismissal allowed Malan to step up for a terrific 39-ball knock.
Losing Jason Roy (27) and Phil Salt (eight) to Umran Malik and Harshal Patel within the first 10 overs did little to stem the hosts' momentum as Liam Livingstone (42 not out) joined Malan in an 84-run partnership before India belatedly stepped up their attack in the 17th over.
Ravi Bishnoi accounted for Malan and Moeen Ali – the latter for a duck – in rapid fashion before Harry Brook (19) and Chris Jordan (11) fell, but India's bowling display fell a long way short of their scintillating outing at Edgbaston last time out as England still posted a mammoth total.
Indeed, the 13 sixes racked up by England represented their most in a T20I innings against India, and they looked set for a comfortable victory when the tourists made a dreadful start with the bat.
India lost Rishabh Pant (one), Virat Kohli (11) and Rohit Sharma (11) during a desperate first five overs, only for the imperious Yadav to drag them into contention with his first international hundred.
But Yadav's 19th-over dismissal at the hands of Ali slowed India's progress, as England clung on to end an underwhelming series on a high.
Magnificent Malan carries England
Malan's 77 – the fourth-best knock of his T20I career and his best against India – proved crucial as England racked up their highest ever score against India in the format, despite another early exit for Buttler.
Yadav falls short despite terrific haul
Yadav was incredibly unfortunate to end up on the losing side after his outstanding innings, falling just short of leading India to a remarkable chase as well as missing out on making history on an individual level.
His 117 was just one short of the highest score ever posted by an India player in the format, with Rohit having smashed an almighty 118 off just 43 balls against Sri Lanka in December 2017.
Bowler Gleeson joins his domestic team-mate in his first selection since succeeding the retiring Eoin Morgan as skipper last month.
The 34-year-old has taken 70 wickets in 64 domestic T20 matches and posted career-best figures of 5-33 against Worcestershire Rapids in this season's T20 Blast.
Elsewhere, there are a mix of familiar names for Buttler and coach Matthew Mott, although Yorkshire bowler Adil Rashid is absent after the ECB gave him permission to make The Hajj pilgrimage to Mecca.
Harry Brook is named in both squads, seemingly the beneficiary of Morgan's retirement.
Brook was an unused member of Ben Stokes' first Test squad, with the red-ball team's own new era getting off to a roaring start with a series whitewash against New Zealand.
Star Test batsmen Stokes, Joe Root and Jonny Bairstow were all named to Buttler's ODI group.
But there is no room for David Payne and Luke Wood, who made the ODI trip to the Netherlands last month, while Dawid Malan only makes the 20-over team.
Tom Banton, James Vince, George Garton and Sam Billings miss out from the T20I squad that toured the West Indies in January.
England T20I squad : Jos Buttler (Lancashire), Moeen Ali (Worcestershire), Harry Brook (Yorkshire), Sam Curran (Surrey), Richard Gleeson (Lancashire), Chris Jordan (Surrey), Liam Livingstone (Lancashire), Dawid Malan (Yorkshire), Tymal Mills (Sussex), Matthew Parkinson (Lancashire), Jason Roy (Surrey), Phil Salt (Lancashire), Reece Topley (Surrey), David Willey (Yorkshire).
England ODI squad : Jos Buttler (Lancashire), Moeen Ali (Worcestershire), Jonny Bairstow (Yorkshire), Harry Brook (Yorkshire), Brydon Carse (Durham), Sam Curran (Surrey), Liam Livingstone (Lancashire), Craig Overton (Somerset), Matthew Parkinson (Lancashire), Joe Root (Yorkshire), Jason Roy (Surrey), Phil Salt (Lancashire), Ben Stokes (Durham), Reece Topley (Surrey), David Willey (Yorkshire).
Buttler was named man of the match in the first Twenty20 International of the series after scoring a blistering unbeaten 68 not out in a crushing eight-wicket win on Wednesday.
The wicketkeeper-batsman damaged his right calf during that match at Sophia Gardens and missed a series-clinching five-wicket victory at the same venue on Thursday.
Buttler underwent an MRI scan on Thursday morning that revealed a small tear, which will keep him out of the final T20 at the Ageas Bowl on Saturday and all three ODIs.
The 30-year-old will return home to commence a rehabilitation programme on Friday, with Jonny Bairstow expected to keep the gloves in Southampton.
Dawid Malan, the top-ranked T20 batsman in the world, has been added to the ODI squad following Buttler's withdrawal.
Cairns suffered a "major medical event" in Canberra late last week and initially underwent an operation in the capital city.
The 51-year-old's wife, Melanie, on Wednesday revealed he has been transferred to St Vincent's hospital in Sydney, where has had undergone another operation.
"As has now been widely reported in the media, Chris suffered a major medical event in Canberra late last week," she said in a statement.
"He initially underwent surgery in Canberra, but the seriousness of his condition is such that he has now been transferred to St Vincent's hospital in Sydney, where he has undergone further cardiovascular surgery.
"Chris' family and friends are heartened by the respectful and warm manner in which this terrible news has been reported, and received by the public, both in New Zealand and around the world, and thank everyone for their warm wishers, prayers and kind words.
"For now, no further statements will be make regarding Chris' situation, and the Cairns family asks that people continue to respect their privacy as they deal with this difficult, upsetting and concerning situation."
New Zealand Cricket CEO David White said: "We're deeply concerned to hear of Chris Cairns' medical emergency.
"Our thoughts are with his family in Australia and here in New Zealand. Chris is a much-loved husband, father, and son - and remains one of our finest all-rounders. We hope he's able to make a full recovery."
Cairns played 62 Tests, 215 ODis and two Twenty20 games for the Black Caps between 1989 and 2006.
The talented all-rounder, 21, was included in an 18-man squad named on Thursday.
Green is the leading run-scorer in this season's Sheffield Shield with 264 at an average of 132 for Western Australia, while he averages 27.83 with the bat and 34.42 with the ball in nine domestic 50-over matches.
Moises Henriques has also been recalled, while Mitchell Marsh has missed out after dealing with an ankle injury.
"Moises is a tremendous cricketer with loads of experience and is a great person to have around the group," Australia national selector Trevor Hohns said.
"His form was extremely impressive in leading the [Sydney] Sixers to the BBL title last summer and he has played well at the start of this season.
"Similarly, Cameron's domestic form has been outstanding and he has carried it through for Western Australia this summer. As a potential player of the future this is an opportunity for him to be part of the squad and build on his experience."
Australia's three-match ODI series against India is set to begin in Sydney on November 27, before the teams do battle in three T20s at the start of December.
Australia: Aaron Finch, Sean Abbott, Ashton Agar, Alex Carey, Pat Cummins, Cameron Green, Josh Hazlewood, Moises Henriques, Marnus Labuschagne, Glenn Maxwell, Daniel Sams, Kane Richardson, Steve Smith, Mitchell Starc, Marcus Stoinis, Matthew Wade, David Warner, Adam Zampa.
The start in Centurion was pushed back because of wet conditions and the contest was reduced to an 11-overs-a-side thrash, with South Africa totting up 131-8, helping by David Miller crunching 48 from 22 balls.
Miller struck three sixes as the home side recovered well from losing opener Quinton de Kock to the first ball of their innings at SuperSport Park.
West Indies made a flying start to their reply as Brandon King and Kyle Mayers took 17 runs from the first four deliveries. King's 23, and 28 from Johnson Charles, helped to put the tourists in a strong position, but it was Powell who played the crucial innings.
The 29-year-old Jamaican hit five sixes in an explosive 43no from 18 balls, holding his nerve after West Indies lost two wickets to Sisanda Magala (3-21) in the 10th over.
Powell's maximum from the second delivery of the 11th over brought the teams level, and he tucked away a single into the leg side from the next ball to seal the win, taking West Indies to 132-7.
Powell starts as he means to go on
The chance to lead arose for Powell when Nicholas Pooran resigned as West Indies' white-ball captain after last year's T20 World Cup.
Powell has taken on the T20I job, with Shai Hope leading the ODI team, and this was a whirlwind beginning for the incoming captain, firstly with the match being reduced to a quickfire slog, and then with the pressure falling on his shoulders with the bat.
He came in at 66-3 in the fifth over, after the breakneck start, and saw the job through, posting his joint-sixth highest T20I score in what was his 47th innings at this level.
Trend to continue?
The last three T20I series between these teams have been won by the touring side, and with two games remaining in this series we might be on for a repeat.
South Africa are experiencing a dire run of series results in T20Is at home, having lost their last four such series, last getting a home success against Sri Lanka in March 2019.
Over the longer course of a full 20 overs it might prove a different story between these teams, with the win for West Indies on this occasion being just the second in their last 16 T20Is away from home. They and South Africa go again on Sunday, also in Centurion.
Pakistan won the ODI series thanks in large part to the brilliance of captain Babar Azam and his superb 66 propelled the hosts to a competitive 162-8 in Lahore.
Babar's composure at the crease was much-needed for Pakistan, who lost Mohammad Rizwan (23) and Fakhar Zaman (0) in successive balls to T20I debutant Cameron Green (2-16).
Adam Zampa finally drew a stray shot out of Pakistan's skipper, who picked out Nathan Ellis to leave his side on 118-4.
Having already dismissed Iftikhar Ahmed, Ellis – the pick of Australia's bowlers with 4-28 – then did the damage through Pakistan's middle order, getting rid of the dangerous Khushdil Shah (24), Asif Ali (3) and Shaheen Shah Afridi (0), though Usman Qadir's flurry of 18 not out boosted the hosts.
Travis Head quickly set about getting the tourists' chase on its way, scoring a rapid 26 that included four boundaries before he was sent packing by Haris Rauf.
Josh Inglis (24) kept up the pace until Qadir struck, but Australia seemed well set before Marnus Labuschagne, Marcus Stoinis and Green were dismissed in the space of 20 balls.
Yet captain Finch anchored the chase as he returned to form following back-to-back ducks in the ODI series, with his steady innings steering Australia into needing 15 runs from three overs.
A costly start to the 18th over from Haris saw McDermott plunder successive boundaries, though the pressure was back on Australia when Finch found Asif in the deep.
Afridi (2-21) rounded off an excellent spell by bowling Sean Abbott for a duck, yet another poor Haris ball handed McDermott the chance to clip away the winning boundary.
Captains come up big
Babar gave yet another exhibition of how he has risen to the top of the batting rankings in another sensational knock - his 66 coming at a strike rate of 143.47.
Yet it was World Cup winner Finch who took the trophy, as he showed plenty of patience to stay at the crease for 18 overs, showing why interim head coach Andrew McDonald backed him to stay on as skipper.
Historic tour comes to a close
It has been a brilliant match-up between Pakistan and Australia over the last month or so and the tourists will finally return home.
Australia have now won each of their past four T20Is against Pakistan, the first time they have gone on such a run, though this was the first meeting in the format between the teams in Pakistan.
Athapaththu claimed figures of three for 21 as the hosts were bowled out for 116 before whacking 44 to fire her side to a seven-wicket victory, which sealed a memorable 2-1 series success in the decider at Derby.
The Sri Lanka captain hit a half-century in Saturday’s win at Chelmsford and again brought the fireworks, plundering two sixes and five fours in her 28-ball innings.
It meant that England lost a T20 series to a team other than Australia for the first time since 2010, while also losing a first-ever white-ball series to Sri Lanka.
The opening ball of the match set the tone for England’s disappointing innings as Danni Wyatt slapped a gentle long hop straight to cover and it got worse after a calamitous run out at the end of the second over, where Maia Bouchier and Alice Capsey were both at the same end.
They never got to grips with Sri Lanka’s array of slower bowlers, with skipper Athapaththu taking three wickets and Udeshika Prabodhani and Kavisha Dilhari both claiming two victims apiece.
Bouchier top scored with 23 while Danielle Gibson added 21 late as England failed to see out their overs.
Athapaththu came out firing and did the leg work of Sri Lanka’s chase in the first seven overs, hitting Kate Cross and 17-year-old Mahika Gaur over the ropes in an array of boundaries.
Her dismissal with score on 65 could have opened the door for England, but they could not make regular inroads and the visitors got over the line with 18 balls to spare.
The selectors announced an initial party of 23 to face the Windies and the Tigers, featuring a number of players who played in an Indian Premier League that was cut short due to the coronavirus pandemic.
They have now added Christian, Agar, Ellis, Ben McDermott, Cameron Green and Ashton Turner.
All-rounder Christian, 38, and wicketkeeper-batsman McDermott will end spells in England with Nottinghamshire and Derbyshire respectively to fly home and complete the mandatory two-week quarantine period before the final squad's scheduled departure for the Caribbean late in June.
Christian has not played for his country since October 2017, while Agar and Ellis will be hoping to make their international debuts.
Promising all-rounder Green made his ODI bow against India last December, while Turner has featured in the 50-over format six times and played 11 Twenty20 Internationals.
Confirmation of the tours are subject to agreement on bio-security arrangements and relevant government approvals.
Cricket South Africa (CSA) has opted to split coaching duties, with Conrad taking charge of the Test side and Walter the limited-overs teams.
Mark Boucher had been head coach for all formats but brought his reign to an end following the T20 World Cup in Australia late last year.
Malibongwe Maketa stepped in on an interim basis following Boucher's resignation, overseeing a 2-0 Test series defeat in Australia.
The new coaching duo have reportedly signed four-year contracts.
A former first-class cricketer, Conrad has coached the South Africa Under-19 side and now gets his chance with the senior team in the longest format.
Dean Elgar's side look highly unlikely to qualify for the 2023 World Test Championship at The Oval following that series loss in Australia.
Walter was previously employed as South Africa's strength and conditioning coach and has the task of turning around the Proteas' white-ball fortunes, with qualification for the 50-over World Cup in India not yet secured.
South Africa failed to progress from their group at the T20 World Cup after suffering a shock defeat to the Netherlands in November.
Conway was 99 not out, becoming the first New Zealand player to score five successive T20 half centuries, as the Black Caps posted 184-5.
A fine showing with the ball, led by Ish Sodhi's 4-28, limited Australia to 131 all out in reply as the hosts enjoyed a dominant victory in Christchurch, a city remembering the devastating earthquakes that struck 10 years ago.
Martin Guptill started this match needing 12 runs to surpass Brendon McCullum's record as the highest run-scorer in this fixture (228) but was dismissed for a duck, caught at backward point off the bowling of Daniel Sams.
New Zealand looked to be in serious trouble when captain Kane Williamson's departure in the fourth over left them on 19-3 and with a lot of work to do.
But Conway laid the foundations with a fine knock, which came up just shy of yielding a century despite 10 fours and three maximums.
Conway was on 88 when he got on strike with three balls left, sending the first for a six and the next one for four, but he could only manage a single off the final delivery.
Aaron Finch's side, having lost back-to-back series against England and India, toiled in response.
Finch himself fell inside the first over and that set the tone, with Australia languishing on 19-4 by the fifth over.
Sodhi was the tormentor-in-chief for the tourists' mid-to-lower order, accounting for Marcus Stoinis, Ashton Agar, Sams and Kane Richardson.
Jhye Richardson, who fetched a "life-changing" bid at the Indian Premier League auction, was the last man to fall in a substandard innings from Australia that was ended after 17.3 overs.
This was just the second home win for New Zealand over Australia in this format in six attempts, with the teams set to meet again on Thursday.
The cancelation of the series comes as New Zealand enforce a mandatory 14-day self-isolation period for those entering the country from midnight on Sunday (local time) amid the global COVID-19 outbreak.
After Australia's 71-run win over New Zealand in Friday's ODI opener played without fans at the SCG, the hosts were due to face the Black Caps in Sydney (Sunday) and Hobart (March 20) for the final two 50-over fixtures.
New Zealand were also set to host a three-match T20 series, starting in Dunedin on March 24, however, the games have been called off as the Black Caps rush home.
"Arrangements are being made to fly the bulk of the squad home this evening [Saturday]," New Zealand Cricket (NZC) said in a statement.
"NZC believes both these series can be replayed in their entirety at a later and more appropriate date.
