Live updates

1:41am - Hockey: And there's the final siren, as Australia move to four wins from four games and NZ slide to one win, two loses and a draw. That leaves the Black Sticks teetering a little in their pool, with their next outings against Argentina on Friday.

1:37am - Hockey: GOAL to Russell

From another penalty corner, Russell produces an indentical stroke that produced his first goal earlier tonight, with two minutes remaining, AUS 4-2

1:35am - Hockey: GOAL to Wickham

It's all fallen apart quickly here in the final quarter, with Australia capitalising on another save from Hayward that isn't sufficiently cleared, AUS 4-1

1:32am - Hockey: GOAL to Govers

Hayward kicks a shot away from goal, but only manages to deflect the ball to Govers unmarked on the far post with no-one between him and the net. He needs no invitation, AUS 3-1

1:26am - Hockey: GOAL to Brand

Finally, pressure tells on the NZ defence, with Brand slotting his second goal of the game to break the tie, AUS 2-1

12:29am - Hockey: GOAL to Russell

NZ level up the score, with a penalty corner that Kane Russell drags perfectly into the top left corner of the goal, 1-1

12:24am - Hockey: GOAL to Brand

Blake Govers steals the ball of the NZ defence and lays it on to Brand, who flicks it past NZ keeper Hayward, AUS 1-0

12:12am - Hockey: Finally tonight, the Black Sticks men take on unbeaten Australia, hoping to improve their 1-1-1 record so far.

NZ currently sit third in this group, with four to advance to quarterfinals, but they were beaten India in their opener, before the Aussies thrashed the Indians 7-1.

11:34pm - Swimming: NZ up now, with Italy, Russia, Australia, Canada, Hungary, Brazil and Hong Kong. Erika Fairweather swimming first and turns in second at the 50m.

Now slipped behind Canada at the 150m and Fairweather will hand over to Carina Doyle in third, with a 1m 57.38s split, which is faster than she managed in her 200m frestyle heat.

Doyle has slipped to fifth after the first 100m of her leg, with Russia and Hungary moving through. She finishes in 2m 02.18s, fifth, with Eve Thomas now in the water.

Thomas has slipped to sixth, behind Brazil now. She finishes with a 2m 00.76s split and hands over to Ali Galyer in fifth.

Galyer falls behind Brazil again and then loses another spot to Italy. Australia finish in 7m 44, winnning by seven seconds. NZ finish seventh in 8m 06.16s, with Galyer clocking 2m 05.85s.

Hold your tickets, Italy were disqualified, so NZ promoted to sixth, but still too slow to advance.

11:22pm - Swimming: In fact, that takes Clareburt through as the third-fastest qualifier.

Next up, the women's 4x200m freestyle relay, with the Kiwis in heat two.

11:18pm - Swimming: Clareburt up now, with eight swimmers already faster than his best time.

Eighth after the opening butterfly lap, now into backstroke. Up to seventh at halfway and now breastroke, not his strongest.

Up to fifth with 50m of freestyle left. Clareburt finishes third with a personal best of 1m 57.27s - great performance, which should take him through to the semis.

11:11pm - Swimming: Moments away from Clareburt's 200 IM heat. He's in heat six with a time of 1m 57.89s - faster than just one other in his race, with the top 16 times progressing.

Hvas of Norway has gone 1m 57.64s in heat three, while four others went faster than Clareburt's best in the fourth heat.

10:30pm - Next up tonight, we have Lewis Clareburt contesting heats of 200m medley at 11:12pm, while the women's 4x200m freestyle heats follow.

Later, at 12:15am, the Black Sticks men take on old rivals Australia in hockey.

10:20pm - Football: The final whistle sounds and NZ progress into the quarter-finals, possibly against Japan at this stage.

The probably should have sealed that spot against Honduras, but let victory slip away. This time, a draw is enough.

NZ and Romania both finish with a win, loss and draw, but the OlyWhites have a better goal difference.

10:19pm - Football: Into the last minute and Stamenic is rolling on the ground after a crude tackle in midfield. NZ have a free-kick in the final seconds.

10:17pm - Football: Four more minutes added. Woud lets a ball roll towards the byline, killing time, and is fouled when he eventually picks up.

10:15pm - Football: Ratiu beats his defender on the right and fires on goal, but Woud is safe.

Ganea makes a run down the right, but the left-footed shot sprays way wide. Stamenic has picked up his second yellow card of the tournament, so will sit out the next match.

10:14pm - Football: Wood has the ball on the edge of the area, but can't control and the defence converges.

10:11pm - Football: Cacace earns a corner with less than five minutes left. Bell's kick curls toward goal, but Wood nudges the keeper in his attempt to header home.

10:05pm - Football: NZ corner and Lewis' cross is headered away. A follow-up shot is also blocked.

Another NZ corner is headed toward goal by Stensness, and Lewis' wild left-foot swing is high and wide.

10;01pm - Football: Cacace crosses and the ball falls for Wood in front of goal, but it's deflected away before he can strike.

9:58pm - Football: Lewis comes on for Garbett.

9:56pm - Football: Wood takes the ball into the area, but it runs behind him for an instant and before he can unleash, the defence converge to defuse the situation.

Romania put in a long ball across goal to the far post and Ratiu headers on goal, but deflected over the bar by Woud. Romania corner is punched awa by Woud.

9:49pm - Football: NZ win a corner - their fifth of the game - and it's cleared without threat. Meanwhile, Korea are now 5-0 over Honduras, so things looking good for the Kiwis.

9:49pm - Football: Romanians falling like ninepins and some passionate appeals for free-kicks, but no calls given.

9:44pm - Football: Meanwhile, while we were enjoying that sevens final, absolutely nothing happened in the football, where it's still 0-0 between NZ and Romania.

Actually, that's not quite true - Korea lead Honduras 3-0 in the Pool B match and if results stand as they are, the OlyWhites will advance to quarter-finals.

As we say that, Romania take a corner and the header barely kept out by Woud, who traps the ball under his knees from point-blank range. Phew!

9:20pm - Sevens: NZ need to score quickly and claim the kick off, but Ng Shiu throws the ball away into touch.

Another penalty against NZ and that may be it, as the final seconds count down. Fiji take a shot at goal to kill time, FIJ 27-12

Fiji defend their Olympic title, but silver to the All Blacks Sevens.

9:18pm - Sevens: Fiji threaten down the left and play under advantage. When the ball goes right, Tuivuaka scores and that could seal it, FIJ 24-12

9:16pm - Sevens: Fiji kick ahead, but it dribbles dead. An attacker runs into Collier, but he's stood his ground and NZ have a defensive crum.

Mikkelson leaves the field. NZ break out down the left, but Ware has the ball knocked free.

9:15pm - Sevens: MCGarvey-Black comes on for Webber. Knewstubb kicks to touch and have a lineout in the 22.

Fiji win the lineout and sprint upfield on attack.

9:14pm - Sevens: NZ spreading the ball and Curry straightens the attack. NZ claim a penalty.

9:13pm - Sevens: Fiji up 19-12 at the break and NZ still need to score next to stay in the contest. Knewstubb kicks off high and just 10m.

9:08pm - Sevens: Curry claims the kickoff and NZ win a penalty. They win a lineout as the halftime siren sounds.

NZ have another penalty and set something up in midfield. Fiji offside again, NZ lose the ball, but Molia picks it up and overpowers a couple of tacklers to score under the posts, NZL 19-12

9:07pm - Sevens: NZ kick off deep and Maqala proves a handful to tackle. NZ penalised, and Wainiqolo is too big and strong down the right touchline to score, FIJ 19-5

9:05pm - Sevens: Fiji kick off deep and NZ have possession for the first time. They build patiently and Curry outpaces the defence to score in the corner, FIJ 12-5

9:02pm - Sevens: Fiji kick off and regain possession, then kick ahead. Knewstubb seems to have the ball covered, but loses it and Maqala forces. Try, FIJ 12-0

9:01pm - Sevens: Curry wins the lineout, but Fiji rip the ball away and Derenalagi rumbles over for the first try, FIJ 5-0

9pm - Sevens: Fiji kick off and win the ball back. They kick ahead, immediately gifting possession back - that's a mistake.

8:58pm - Sevens: Both anthems played before the final, lots of emotion. Curry, Mikkelson, Collier, Knewstubb, Ware, Webber & Molia to start for NZ.

8:57pm - Football: We must divert our attention from the OlyWhites to focus on the sevens final, but we'll keep half an eye open for any goals...

8:53pm - Sevens: Moments away from the All Blacks Sevens taking on Fiji for gold. Both teams run out on the field...

8:51pm - Football: Kiwis go close again, with the ball bouncing in and out of the area, and Just eventually unleashing a left-footer into the side net.

8:49pm - Sevens: With seconds remaining, Argentina lead 17-12 and win a penalty that they kick to touch. Celebrations begin for the South Americans, who take home the bronze medal.

8:46pm - Football: Champness puts a dangerous cross into the box, but can't find Wood and the Romanians clear. NZ with a corner, the ball bounces in the area, but cleared again.

8:44pm - Sailing: Better day for the Kiwis on the water today, with the men's 470s in second overall after two races, Burling & Tuke improving to fiifth, Junior in eighth and the women's 499er FX in ninth, all in contention now for medals races.

8:41pm - Football: Florescu gets free on the right post and fires towards goal, Woud barely keeps it out and concedes a corner.

The keeper rises high to claim the corner kick and clear.

8:37pm - Sevens: Argentina have a 12-5 lead over Great Britain, as halftime approaches. Tries to Bazan Velz and Moneta cancel out the quick opener from Brit Ben Harris.

8:35pm - Football: Romania take a corner, but the NZ defence nods it clear and counterattacks.

8:32pm - Football: OlyWhites have first attacking opportunity with a Stensness corner that crosses goal, begging for a deflection, but bouncing through for a goal-kick.

8:27pm - Sevens: Argentina and Great Britain are taking the field for their bronze-medal game, with NZ v Fiji now half an hour away...

8:11pm - Football: We're 20 minutes away from kickoff between the OlyWhites and Romania, with the Kiwis needing victory - or a draw and other results to go their way - to progress out of pool play for the first time. 

Here's the NZ line-up...

OlyWhites: 1-Michael Woud, 3-Liberato Cacace, 4-Nando Pijnaker, 7-Elijah Just, 8-Joe Bell, 9-Chris Wood, 10-Mark Stamenic, 11-Joe Champness, 16-Gianni Stensness, 17-Callan Elliot, 19-Matthew Garbett

Substitutes: 6-Clayton Lewis, 12-Callum McCowatt, 13-Jamie Searle, 14-George Stanger, 15-Dane Ingham, 18-Ben Waine, 20-Sam Sutton

8:08pm - Cycling: Slovenian Primoz Roglic has taken out the cycling time trial by more than a minute, from Dutchman Tom Dumolin and Aussie Rohan Dennis. Roglic is George Bennett's Jumbo Visma teammate and has had a horrible season so far, crashing out of the Tour de France, so nice to see him salvage something at Tokyo.

Kiwi Patrick Bevin finishes 10th, a solid performance, but 2m 20s back, while Bennett is 25th - time trial is not really his thing.

8pm - Welcome to the Newshub night shift for a gripping evening of Games action, including a shot at sevens gold.

Patrick Bevin and George Bennett have both completed their road cycling time trial, and now wait to see where they finish. Neither are in medal contention.

Luuka Jones has qualified for the canoe slalom semi-finals and Callum Gilbert has squeezed into his kayak semis, as the last of 20 qualifiers.

Our 49er FX and Nacra sailors are just finishing their last races of the day.

7:58pm

At this rate, Bevin's going to finish 10th.

7:57pm

Bevin has dropped to fifth place after the pair of Tom Dumoulin of Netherlands took the lead, before Slovenia's Primoz Roglic takes it from him.

7:50pm

Bevin crosses the line in provisionally third place, but there's still some strong riders to finish.

7:38pm

Bevin is ninth at the 22km mark of the time trial. The race is 44.2km, so plenty of time to go.

7:23pm

But Gilbert can't put in a quick enough run. He clocks 101.15s, and falls short of the semi-final.

7:20pm

Gilbert returns to action in the C1 canoe slalom. He needs to beat a time of 95.68s to qualify.

7:17pm

Bevin is fourth fastest early into his ride. Colombia's Rigoberto Uran currently leads.

6:54pm

And Patrick Bevin has started his run in the time trial.

6:36pm

Micah Wilkinson and Erica Dawson have finished 11th in their first race of the Nacra 17 class.

6:25pm

Molly Meech and Alex Maloney have finished 11th in race four of the 49er FX, and has them 14th in the standings with eight races to go.

They still have two races left tonight.

6:15pm

George Bennett has finished with the fifth best time in cycling's time trial, so far.

6:13pm

Marcus Daniell and Michael Venus' semi-final opponents have been decided.

They'll face Croatia's Marin Cilic and Ivan Dodig, who defeated Great Britian's Andy Murray and Joe Salisbury.

6:04pm

Callum Gilbert's finished 23rd of the 24 strong field in the canoe slalom K1. 

There's another qualifying session later tonight, he'll need a top 20 spot to get through.

5:45pm

Natalie Rooney finishes her first day of trap shooting qualifying in 18th place.

The top six from the five qualifying rounds will advance for a chance of a medal.

5:33pm

George Bennett is fifth at his first checkpoint, but 45 seconds behind the leader, Canada's Hugo Houle.

5:32pm

Just to collate where things stand with the sailors:

Paul Snow-Hansen and Dan Willcox sit second in the 470 class after two races.

Peter Burling and Blair Tuke are fifth overall after four races in the 49er.

Josh Junior is eighth overall in the finn class.

Micah Wilkinson and Erica Dawson in the Nacra, and Alex Maloney and Molly Meech in the 49erFX are still to come this evening.

5:16pm

Callum Gilbert's first run hasn't gone to plan. He's missed gate 10 and incurred a 50-second time penalty.

He still has a second run to try and advance though, so no need to panic.

5:15pm

George Bennett is underway in the time trial!

5:13pm

Callum Gilbert is up in the canoe slalom, racing in the men's K1.

5:11pm

Peter Burling and Blair Tuke are up into fifth place in the 49er class. They struggled on their first day, but have come back with a second placed finish in race four - their best result so far.

They've still got eight races to go in qualifying.

5:00pm

To the sailing, where Paul Snow-Hansen and Dan Willcox have made a decent start to their 470 class regatta.

Sixth place in race one, and second in race two.

There's still eight races of qualifying to come, but a handy start nonetheless.

They sit second behind Australia's Matthew Belcher and Will Ryan.

4:57pm

The men's cycling time trial begins at 5:00pm.

George Bennett is expected to be up at around 5:15pm. Patrick Bevin should race at around 6:52pm

4:50pm

What a race from the Kiwis!

3:56pm

At the 1500m, and New Zealand are in front! 

3:55pm

Approaching halfway. GB still first, NZ still second. USA are third, Romania fourth.

Australia will be watching the final from the couch.

3:53pm

Coming to the first 500m, Great Britain are first, but New Zealand are second!

At present, Australia will miss out.

3:53pm

The top four all qualify for the final. NZ are up against Romania, USA, Australia and Great Britain.

Great Britain have taken the early lead.

3:52pm

They're away!

3:48pm

Back to rowing, where the New Zealand men's eight have the chance to book their spot in their final, as the repechage is about to get underway.

3:46pm

And they've done it! Venus and Daniell are through to the semi-final, and knocked out the third seeds!

3:45pm

Venus and Daniell have two match points up their sleeve over Colombia.

3:41pm

The Black Sticks women have grabbed a goal back, they trail Spain 2-1.

3:40pm

Back to the tennis, and Venus and Daniell are 6-2 up in the super tiebreak for a spot in the semi-final.

First to 10 wins.

3:38pm

ROC and Spain take the other two final spots on offer.

They'll join Greece, Great Britain and Canada in the hunt for the gold.

3:37pm

ROC and Spain make a charge as we approach the finish line. 

But it won't matter, Prendergast and Gowler are through, and they're through in style!

3:35pm

At the 1500m mark, and it's not even close. They've got a four second advantage over ROC.

Barring disaster, this should be a second final of the Games for Prendergast and Gowler.

3:32pm

Coming up to the 500m mark. Prendergast and Gowler are comfortably in front!

ROC are second, Romania third, USA fourth, Italy fifth and Spain last.

3:30pm

Gowler and Prendergast are away in their semi-final! They'll need to finish in the top three to book their spot.

3:28pm

Colombia have taken the second set 6-3 against Daniell and Venus in the tennis.

If the Kiwis can get up and take the third, then they'll be guaranteed a shot at a medal.

3:17pm

Spain have just gone 2-0 up in the hockey, giving the Black Sticks women a lot to do.

3:12pm

Back to the rowing, where the women's pair of Kerri Gowler and Grace Prendergast will race for a spot in their final at 3:30pm.

3:08pm

Elsewhere, Marcus Daniell and Michael Venus are one set to the goods in the doubles tennis quarter-final.

They took the first set 6-3 against Colombia, but are 4-1 down in the second.

3:07pm

Romania, Denmark and Spain take the finals spots from this race.

Australia get home in fourth, New Zealand get home last - out of medal contention.

3:05pm

The Kiwi crew are struggling. They're more than 12 seconds back at the 1500m mark.

3:03pm

Stephen Jones and Brook Robertson are now racing for a spot in their men's pair semi-final.

3:00pm

The Black Sticks women are currently 1-0 down against Spain.

2:21pm: FULLTIME - NZ 29 GB 7

That's that! New Zealand will play for gold, they'll meet either Fiji or Argentina in the final!

2:19pm: 14 mins - NZ 29 GB 7

TRY NEW ZEALAND

Last real chance for Great Britian you'd have to think - but Amanaki Nicole wins a turnover!

Can NZ finish this off? They can, Curry barges his way over for another try!

The kick misses.

2:16pm: 12 mins - NZ 24 GB 7

TRY NEW ZEALAND

There's another! Knewstubb finds Collier from the kick off, and he races down the left wing to score in the corner!

The conversion's no good.

2:15pm - 12 mins - NZ 19 GB 7

TRY NEW ZEALAND

GB kick into touch, so another N lineout. Knewstubb throws, and Mikkelson runs at the left flank. 

They go back the other way to Curry, who gets to the 5m line. They go back to the other wing, where Ware has one man to beat - and he does!

The conversion hits the posts.

2:13pm: 10 mins - NZ 14 GB 7

Knock on from GB off the kick, NZ scrum.

Knewstubb feeds, Molia runs off the back. They go wide to Curry, who's tackled. 

Nanai-Seturo tries to dance through, but GB defend well. NG Shiu looks to slip through, and offloads to Knewstubb, but GB win a penalty.

2:12pm: 8 mins - NZ 14 GB 7

Second half about to begin, Knewstubb kicks off.

2:10pm: HALFTIME - NZ 14 GB 7

TRY NEW ZEALAND

Penalty for New Zealand, they'll restart with a lineout. Another penalty against GB though, so we'll have another lineout.

Knewstubb throws, and gets it back from Ng Shiu. Webber takes the line on and he's tackled. Time almost up in the first half.

They go wide to Molia, who draws in the last defender before finding Ware outside him! Ware races away to dot the ball down, but the referee wants to check if his foot was in touch?

We're good, NZ score before the break, and the conversion is nailed from in front by Knewstubb.

2:05pm: 5 mins - NZ 7 GB 7

TRY GREAT BRITAIN

But GB hit back straight away! Norton slips through the Kiwi defence and he runs in to score under the posts.

The conversion is good, we're all square.

2:04pm: 4 mins - NZ 7 GB 0

TRY NEW ZEALAND

The All Blacks Sevens go to the right wing, and Curry dives over to open the scoring!

NZ on the board, and GB haven't even touched the ball!

2:02pm - 3 mins - NZ 0 GB 0

NZ are deep in their own territory, but make good use of the ball. Molia tries to break the line down the left, but has to recycle back infield.

Knewstubb tries to break, but GB defend well. Ng Shiu has made a couple of good touches, but again the GB defence holds.

Collier breaks into the opposition half. Webber is high tackled and NZ have a penalty.

2:01pm: KICK OFF - NZ 0 GB 0

We're away! Great Britain kick off to NZ.

1:58pm

The ball's been delivered by a motorised car, as has been the case all tournament.

Kick off's just moment's away.

1:55pm

Here we go then! The All Blacks Sevens face Great Britain for a spot in the final.

Regardless of what happens here, NZ will play for a medal later tonight.

12:54pm

As you'd expect, there has been plenty of emotion from Brooke Donoghue and Hannah Osborne after their silver medal win.

"I'm pretty overwhelmed," a tearful Donoghue told Sky Sport.

"Just incredibly proud of us and think we had an awesome race... we absolutely did our best and I'm stoked we were able to medal."

Osbourne adds: "We absolutely trust each other 100 percent and it comes down to the programme. Rowing New Zealand, they've been fantastic.

"I'm so happy to have been with Brooke, she's just phenomenal."

***

Kia ora, good morning and welcome to Newshub's live coverage of the Tokyo Olympics on a day that contains a couple of excellent gold-medal chances for New Zealand.

First up, Brooke Donoghue and Hannah Osborne take to the Sea Forest Waterway, as the first Kiwi crew to contest a final at the Games rowing.

Donoghue and Olivia Loe are actually reigning world champions in this event, but NZ Rowing sprung a big surprise in the Olympic selections, opting to replace Loe with Osborne, who helped Donoghue to the national double title in February.

A typhoon warning has kept rowing crews off the water for the past two days, but in the semi-finals, New Zealand clocked the third-fastest time (7m 09.05s), while finishing second behind Romania in their race.

The Netherlands also beat the Kiwis in the second semi, while Canada, USA and Lithuania were within a couple of seconds, as they also progressed to the medal race.

Also on the rowing programme, the NZ men's and women's pairs, and men's eight will also try to advance to finals later in the week.

The All Blacks Sevens have already booked themselves a medal shot today, when they face Great Britain in the semi-finals. Win and they would progress to tonight's final, but a loss would still them contest the bronze-medal playoff.

They have cruised through the tournament unbeaten so far, dispatching Canada 21-10 in the quarter-finals to progress this far.

The NZ men were disappointing at Rio 2016, losing to the Brits and Japan in pool play, and eliminated by eventual gold medallists Fiji in the quarter-finals, before beating Argentina for fifth.

Fitting, Argentina and Fiji will contest the other semi this time.

After finishing seventh in the 400m individual medley final, swimmer Lewis Clareburt returns to the pool for the 200m medley heats, while the OlyWhites take a shot at more NZ football history, needing only victory over Romania to advance out of pool play for the first time.

Olympic setback sparks reset for gold-medal favourite Black Ferns Sevens

The Black Ferns Sevens admit they've had to make internal changes over the last five years, if they want to achieve the only thing that's so far eluded them.

The NZ women go into the Tokyo Olympics as firm gold medal favourites, largely thanks to an overhaul in their team culture after their gold-medal loss to Australia at Rio in their Olympic debut.

There isn't much the Black Ferns Sevens haven't achieved in their nine-year existence, but their one Olympic memory is painful. Pipped by Australia for gold in Rio five years ago, for them, Tokyo is about redemption.

"The massive elephant in the room is that we haven't got a gold medal at the Olympics, so that's our No.1 goal," says NZ star Michaela Blyde. "We've been working really hard for the last five years to turn that silver into a gold."

And to do that, they've had to take an honest look at themselves.

Top of the agenda was changing an attitude that prioritised success on the field before their culture off it.

"It drove us to change things," says captain Sarah Hirini. "We knew we had to be better, we had to be better people, have a better culture."

Says Tyler Nathan Wong: "We pretty much went back to the beginning and tried to set good values, good morals... a strong foundation really." 

As painful as losing to Australia was, it taught them valuable lessons and coach Allan Bunting is convinced they’re a better team because of it. 

"Complacency, they call it the devil, right," he says. "When you're winning all the time, you can kind of fall asleep, but not just the silver medal - we’ve had a couple of failures."

The reset has worked wonders. Since their Rio heartbreak, they've won Commonwealth Games gold, the Sevens World Cup and three out of the four world series.

They’re now in the box seat for Olympic gold, but with that, comes big expectations.

"It is everywhere," says Hirini. "You're getting it from media, you're getting it from family, you're getting it from random people who just watch our team, so it's hard, if i'm completely honest... it is hard."

But as the Black Ferns Sevens know all too well, nothing worth fighting for ever comes easy.
