Martin Guptill starred as New Zealand equalled their six-hitting record before holding on to win a nail-biting second Twenty20 against Australia by four runs in Dunedin.

Guptill thundered 97 off 50 balls, including eight sixes and six fours, before being caught off Daniel Sams' bowling to miss out on a third career T20 international century as the Black Caps posted a bumper 219-7.

Captain Kane Williamson's 13th T20 half-century was subdued by comparison, hitting three sixes on his way to 53 runs from 35 balls, while James Neesham crashed six maximums to finish unbeaten on 45 from 16 balls.

The hosts' 18 sixes at University Oval tied their all-time record in a T20 international and proved a shade too much for Australia to chase down, as Mitchell Santner claimed 4-31 to rip through the middle order.

Josh Philippe (45 off 32) had steadied the ship, before Marcus Stoinis and Sams came together at 113-6 and picked up the pace in the last seven overs to give New Zealand a major scare.

Stoinis recorded his first T20 half century as Australia closed on an unlikely victory, needing 36 off the final three overs, and 15 off the last, but Neesham's full toss saw Sams caught for 41 to end a thrilling partnership of 92 runs off 37 balls.

Neesham tempted Stoinis into a big shot, which ended his innings for 78, and the tourists came up short on 215-8 as New Zealand sealed a 2-0 lead in the five-match series, going into the third T20 in Wellington on March 3.

The hosts came out swinging from the off, with Guptill posting 17 runs in the opening three overs, but the Black Caps were temporarily slowed when Kane Richardson claimed Tim Seifert (3) with his first ball.

But Guptill blazed through the rest of the power play, thumping a pair of sixes off Adam Zampa's bowling, before bringing up his half century from 27 balls and taking the score to 59-1 off seven overs.

Australia controlled the run rate over the next few overs until Williamson opened up with a maximum off Ashton Agar as New Zealand made it to 85-1 at the halfway point of the innings.

Guptill slammed back-to-back sixes off Stoinis to take his team past 100, and made it four maximums in the space of five balls as a Kane Richardson over was crunched for 21 to bring up the 100 partnership.

Williamson brought up his 50 for 32 balls and Guptill fell three runs short of 100, with Stoinis taking the catch in the deep, before Neesham teed off with three straight sixes.

The tourists gave themselves a chance with Jhye Richardson and Kane Richardson conceding only 10 runs combined off the 18th and 19th, but their hopes of chasing 220 suffered a blow when Matthew Wade (24) fell to Tim Southee (1-47) to leave them at 34-1.

After Aaron Finch lost his wicket to Ish Sodhi for 12, Santner took control, removing Glenn Maxwell (3) and claiming three more wickets in a single over – including Philippe – to leave Australia needing 107 with seven overs remaining.

But the mood turned quickly as Stoinis and Sams' electric partnership created a tense finish before the pair were both caught off Neesham's bowling to leave the New Zealanders breathing a sigh of relief.

Devon Conway starred with the bat at Hagley Oval as New Zealand won the first of five Twenty20 clashes with Australia by 53 runs.

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.

Australia will be counting on the stars of the Big Bash to step up when they attempt to stop the rot in a five-match Twenty20 International series against in-form New Zealand.

Aaron Finch's side go into the first match of the series at Hagley Oval on Monday looking to avoid a third consecutive series defeat following losses to England and India.

The Black Caps, on the other hand, have won their last two against West Indies and Pakistan as they build momentum ahead of the T20 World Cup, which starts in October.

Australia will be without the likes of Steve Smith, David Warner and Mitchell Starc, with 19-year-old spinner Tanveer Sangha set to make his debut and Jhye Richardson back in the squad.

Richardson, Glenn Maxwell and New Zealand paceman Kyle Jamieson should have a spring in their step after landing lucrative Indian Premier League deals this week.

Paceman Richardson has not played a T20 for his country for two years, but gets the chance to put shoulder injury woes behind him after an impressive Big Bash campaign.

There were doubts over Martin Guptill's fitness for the opening game in Christchurch, with the promising Finn Allen on standby, but the dangerous New Zealand opener is expected to be available.

Jhye on a high after striking it rich

Richardson was the leading wicket-taker in the Big Bash with 29 for Perth Scorchers, prompting Punjab Kings to fork out 14 crore (£1.4m) for his services.

He said after going for such big money in Thursday's auction: "It felt like I wasn't watching it. After everything that's happened you are obviously really excited then you hit this massive wall, it was pretty late, I had all this emotion, all the adrenaline, a load of messages coming through on my phone and then completely crashed and felt exhausted.

"I feel like I played a game, mentally exhausted myself. Still sinking in, that's for sure. I think it's an amazing result. It's life-changing to be honest.

Maxwell went to Royal Challengers Bangalore for the same fee, while Riley Meredith will face Australia's trans-Tasman rivals on the back of also being picked up by Punjab. Jamieson will be out to show why RCB paid 14.25cr (£1.5m) to land him.

Guptill backed to show class is permanent

Guptill has been struggling with a hamstring injury, but the 34-year-old appears to be ready to start the series.

Although Guptill is comfortably New Zealand's leading run scorer in the shortest format, he is in a poor run of form, but head coach Gary Stead has backed the explosive right-hander to come good.

"Gups is a class player and has been a class player for a long time. Form and what people do while in form can change perceptions so quickly," said Stead.

"But we have a number of people who are capable of playing international cricket and that's exciting for us."

Key series facts

- This will be the sixth meeting between the Black Caps and Australia in New Zealand in T20Is and their first at Hagley Oval. New Zealand have won only once against Australia in this format on home soil.

- New Zealand have lost only one of their last five completed T20Is at home (W4). Their only previous match at Hagley Oval ended in a seven-wicket loss to England (November 2019).

- Australia have the highest catching success rate of any Test-playing nation in the shortest format since the start of last year (91.8 per cent); New Zealand have taken 75 per cent of their catching opportunities in that time.

- Sangha took 21 wickets at an average of 18.3 in the recent Big Bash, the most by a teenager in a single edition of the competition.

- Guptill has scored 217 runs in T20 matches between the trans-Tasman rivals. He is just 12 runs shy of eclipsing Brendon McCullum’s record as the highest run-scorer in this fixture (228).

Sam Curran has been ruled out of England's plans for the ongoing Test series against India because flying him in for the fourth match would have been too complicated.

It had been intended that Curran would travel to Ahmedabad to be available for what will be England's final Test of the tour, starting on March 4.

But the England and Wales Cricket Board (ECB) said on Thursday that "making secure arrangements for such a journey proved too great a logistical challenge".

Surrey all-rounder Curran played in both of England's Tests against Sri Lanka in January, but he returned home after the series – alongside Jonny Bairstow and Mark Wood – in order to take a break from the team's biosecure bubble.

While Bairstow and Wood have returned to training and are expected to be able to play in the third Test next week, Curran was given extra time off. The 22-year-old, who also represented Chennai Super Kings in the IPL, has spent extended time in team bubbles since July 2020.

England take on India in five Twenty20 internationals and three ODI matches throughout March, and Curran will join members of the limited-overs squad travelling on a charter flight on February 26. He will arrive too late to be considered for the final Test, the ECB indicated.

With no direct flights available from the United Kingdom, Curran would have had to make a stop-over on his way to the Ahmedabad Test. That would have added more risk of contracting the COVID-19 virus, while he would have had to isolate on his arrival in India had any other passenger on his commercial flights returned a positive test.

An ECB spokesman said: "To give Sam the best chance of minimising his risk of exposure to the virus, it was decided to delay his return so that he could travel on the charter flight with the white-ball squad members due to fly on 26 February."

Over 21 Tests with England, Curran has taken 44 wickets for an average of 32.52, while he has 14 limited-overs wickets to his name.

Mohammad Nawaz and debutant Zahid Mahmood starred as Pakistan held their nerve to a seal a 2-1 Twenty20 series win over South Africa despite the best efforts of David Miller and Tabraiz Shamsi.

The Proteas were rocking at 65-7 and thinking of the plane home, with the brilliant Zahid taking 3-40 and Nawaz 2-13 to leave the tourists in a spin in Lahore.

All-rounder Miller made it a contest by clubbing an electric 85 off just 45 deliveries to steer South Africa to 164-8.

Shamsi's outstanding 4-25 made things even more interesting but ultimately the poor showing from the top order told as Pakistan secured a four-wicket win with eight balls to spare.

South Africa started poorly as Mohammad Nawaz's ripper clipped off Reeza Hendrick's (2) thigh and from his next over more early turn saw JJ Smuts (1) sky one that Babar Azam pouched running back from the ring.

Pite van Biljon (16) struck Hasan Ali for three consecutive fours in the sixth over before trying for one too many and seeing the spinner find a huge gap.

Zahid then came to the fore, Heinrich Klaasen (0) top-edging to short fine leg and Janneman Malan trapped lbw, while Andile Phehlukwayo (0) survived a leg before appeal in the same over.

Phehlukwayo fell to Usman Qadir in the next over and Zahid had a third when Dwaine Pretorius (9) - star of the second T20 - had his middle stump torn up.

It was Miller time from there, though, as South Africa's dangerman single-handedly made it a contest - slapping seven sixes and five fours in a sensational knock.

Miller cleared the ropes a couple of times off Zahid in the 13th over, before unloading for four sixes from the final set off Faheem Ashraf to give Pakistan a genuine chase.

Pakistan were looking pretty serene with a 51-run opening stand between Mohammad Rizwan (42) and Haider Ali (15) but Shamsi's turner left the latter's technique exposed and the same man had the former trapped plumb lbw.

Things became even more tense with Shamsi accounting for Hussain Talat (5) and Asif Ali (7), with Babar's industrious 44 coming to an end between those dismissals.

Faheem fell for 10 as Pakistan's legs wobbled but Nawaz (18) and Hasan (20) steered the hosts over the line, the latter clubbing a six over midwicket to seal the series in style.
