What you need to know

New Zealand enjoyed a marvellous medal run on Tuesday, with paddler Lisa Carrington winning two gold - one with Caitlin Regal - on the water, while Peter Burling & Blair Tuke took silver in the 470 sailing and boxer David Nyika sealed a bronze-medal finish in the heavyweight division.

Our best medal hopes today rest with our men's pursuit team, who race for bronze at the cycling velodrome (8:59pm), and 470 sailors Paul Snow-Hansen and Daniell Wilcox, who sit fourth going into the double-points medal race (5:33pm).

Also Rio 2016 silver medallist Lydia Ko opens her golf account (11:41am).

Live updates

12:21am - Weightlifting

Opportunity here for Liti, as Toychyyev of Turkmenistan does not follow through on his attempt at 241kg. If Liti can manage this on his last attempt, he will be in a medal spot, with Talakhadze to come.

No, he can't get underneath it and blows a kiss to the crowd. He's a popular man and he's done New Zealand proud tonight.

12:15am - Weightlifting

Orsag misses his third, so Liti will at least beat him. He comes out to attempt 236kg, which would get him back into fourth.

He wobbles, but gets two white lights. That's 5kg heavier than he's ever lifted before and his total is a best by 11kg. 

12:12am - Weightlifting

Orsag misses another lift at 235kg, so he's in danger of not registering a clean and jerk.

12:09am - Weightlifting

Kuworge manages to stick 234kg and is cleared by the judges - they are reviewing it, but it stands. That puts him ahead of Liti.

12:04am - Weightlifting

Orsag makes a big mistake at 232kg, dropping the bar too early, and then Kuworge can't handle 233kg. Liti is up next, but passes to 236kg.

11:58pm - Weightlifting

Liti addresses 299kg, which would put him in second so far. He's successful.

11:56pm - Weightlifting

Liti has delayed his entry to 229kg, allowing a couple of his rivals to lift first. Kuworge lifts 225kg, but Asaad of Syria is red-lighted on 228 - he appeals and the lift is reinstated.

11:38pm - Weightlifting

After taking 215kg with his second attempt, Talakhadze puts a world record 223kg on the bar and achieves it. Impressive.

Now we move to the clean and jerk, where Liti is due to start on 226kg - he lifted 229kg at Gold Coast. The early group maxed out at 218kg, so this is where he dominates them.

11:33pm - Weightlifting

Meanwhile, Georgian Talakhadze steps in after everyone else has failed and easily snatches 208kg, a new Olympic record.

11:21pm -Weightlifting

He's already beaten Dutch teenager Kuworge, who lifted 175, but failed twice at 180kg.

11:14pm - Weightlifting

He's gone to 183k and hoists it above his head, but the judges have red-lighted him. Liti looked like he knew something was amiss and the NZ management don't appeal the decision, so he has to be happy with 178kg.

11:11pm - Weightlifting

At Gold Coast 2018, Liti lifted 174k on his way to the Commonwealth Games gold medal, so he's already beaten that. Looks like he'll go to 181kg for his third attempt here.

11:08pm - Weightlifting

Liti goes to 178kg and absolutely bosses the bar. This looks easy for him, so will be interesting to see where he goes for his last attempt. 

11:06pm - Weightlifting

The bar has gone to 175k, with Liti due to attempt this. Czech Orsag and Kuworge of the Netherlands have already succeeded with this weight.

11:02pm - Weightlifting

Liti has nominated a starting weight of 173kg for the snatch, which is the lightest of the seven lifters, so he's first up.

He lifts it easily.

The afternoon session was actually won by Hungarian Nagy, who snatched 178kg and a 396kg total, so that must be Liti's first goal.

10:54pm - Weightlifting

Time to check out Commonwealth Games champion David Liti at the weightlifting +109kg division, where he had originally been placed in the afternoon pool, but has been promoted into the evening session with the big boys.

10:01pm - Equestrian

Kiwi Daniel Meech is the first rider up in the showjump final - the lowest qualifer of the 30 that progressed from qualifying, with a clear round, but two time faults last night. He's knocked down three rails - four penalty points each - with a couple of time penalties, so he's unlikely to feature in the final placings. 

Meanwhile, there's word that the women's golf - featuring Kiwi Lydia Ko - may be shortened to a three-round tournament, with weather expected to impact Saturday's scheduled play. A decision will be made at the end of tomorrow's second round.

Next up for New Zealand, David Liti takes on the big boys of weightlifting in the +109kg division, starting 10:50pm NZ.

9:33pm - Track cycling

Phew, one last Kiwi at the velodrome tonight, with Sam Webster still alive in the round of 16 sprints. He's up against Vigier of France...

Webster has the lead with a lap to go and holds the Frenchman off to advance to the quarter-finals tomorrow.

9:09pm - Track cycling

Well, we don't have time to recover from that disappointment before Italy race Denmark for gold in what promises to be a world record.

Italy lead early, but the world champion Danes have now edge ahead and powering away.

The Italians are whittling away at the lead with a lap remaining and just catch Denmark on the line with a new world record of 3m 42.032s, winning by just 0.171s - incredible race!

9:02pm - Track cycling

The Aussies have their own drama this Games, after their team had a gear malfunction in qualifying and lost one of their riders.

Here they are racing NZ for the bronze and they lead early.

It's essentially neck and neack through 850m, but NZ have the lead at 1000m.

Still neck and neck through halfway, with Kiwis slightly up.

NZ have lost a rider and the third has dropped off the back, will be hard to win from here...

Australia have caught the last NZ rider and that gives them the bronze medal - disaster for the Kiwis!

9pm - Track cycling

Canada take fifth 3m 46.324s, slower than Britain, and they almost catch Germany, despite dropping their fourth rider very early in the journey.

Now NZ v Australia...

8:54pm - Track cycling

Canada will race Germany for fifth and then the Kiwis v Australia for bronze...

8:48pm - Track cycling

After their spectacular crash with Denmark last night, the British - defending Olympic champions - have been relegated to a rideoff for seventh with Switzerland. They'll struggle to pick themselves up from the drama of the semis, but they're up early.

The British clock 3m 45.636s, which isn't as fast as the Italians or Kiwis last night, when they shattered the world record.

8:36pm - Track cycling

Ethan Mitchell is contesting the sprint repechages, but he's trailling home his two opoonents, with just the winners advancing. Awang of Malaysia moves on, Mitchell's night is over.

Next up for the Kiwis are the pursuit team, riding for bronze against Australia.

8:20pm - Track cycling

Ellesse Andrews wins her repechage, and she'll advance to the quarter-finals!

8:00pm - Track cycling

And Webster beats Rudyk! He advances to the next stage.

7:42pm - Track cycling

That was heat one. Sam Webster is in heat seven. 

He'll be up against Poland's Mateusz Rudyk.

7:40pm - Track cycling

Hoogland takes it easily. He advances, while Mitchell drops into a repechage.

7:39pm - Track cycling

Back to the men's sprint. Mitchell is up in the first race, up against Jeffrey Hoogland of the Netherlands.

Hoogland set a new Olympic record to take top spot earlier this evening.

7:31pm - Track cycling

Andrews ends up on the outside of the front three, and has a lot of work to do coming towards the finish!

Can she get there? No! 

Ellesse Andrews finishes in fourth spot. 

Ukraine's Olena Starikova wins, and Japan's Yuka Kobayashi takes second to advance straight to the quarter-finals.

7:29pm - Track cycling

And they're away!

7:26pm - Track cycling

Here we go then, Ellesse Andrews up in heat four of the women's Keirin.

She's in a heat of six riders, the top two progress with the others dropping into a repechage.

7:15pm - Track cycling

The women's Keirin is the next event. Kiwi Ellesse Andrews is in heat four.

7:09pm - Track cycling

Kenny gets home with the eighth place, and that decides the top 24.

Webster comes home in 18th, while Mitchell scrapes in with 24th.

7:06pm - Track cycling

Netherlands' Jeffrey Hoogland takes first place and sets a new record, with 9.215s.

Great British icon Jason Kenny will finish us off.

6:59pm - Track cycling

Webster comes away with a time of 9.621s, good enough for 11th.

Mitchell has dropped to 17th, but there aren't enough riders left to see him out for the next round, so both Kiwis will advance!

6:58pm: Track cycling

World record holder Nicholas Paul is up, but he can't beat Carlin's time either!

That was rider 22, so Webster is up next.

6:48pm - Track cycling

Fifteen riders have gone. Mitchell is 11th, Carlin still leads.

6:44pm - Track cycling

Great Britian's Jack Carlin sets the fastest time - and a new Olympic record - to take top spot at 9.306s.

Mitchell has been pushed down to sixth after 11 riders.

6:41pm - Track cycling

Canada's Nick Wammes has taken over as the leader with a time of 9.587s.

Mitchell has dropped to fifth after nine riders.

6:38pm - Track cycling

We're through the first five riders, Ethan Mitchell is the first Kiwi up.

And he finishes with the third fastest time so far, 9.705s.

Poland's Patryk Rajkowski is the current leader with 9.594s.

6:30pm - Track cycling

Each rider will complete three and a half laps.

Mitchell will ride sixth, Webster will be 23rd.

Trinidad and Tobago's Kwesi Browne is first up, he finishes in 9.66 seconds.

6:28pm - Track cycling

It's going to be a huge night in the velodrome for the Kiwis, starting with the men's sprint.

Ethan Mitchell and Sam Webster both won silver in Rio de Janeiro, but that was part of the team event alongside Eddie Dawkins.

What can they do tonight.

6:13pm - Track cycling

The next Kiwis up are the men's sprint, racing in qualifying at 6:30pm.

Ethan Mitchell and Sam Webster are both up, needing to finish in the top 24 of 30 to reach the next round.

6:01pm - Sailing

Australia win the medal race, Sweden get home second to seal silver.

The Kiwis get third place and USA fourth, but Spain have done enough to take the bronze!

Paul Snow-Hansen and Dan Willcox will finish in an agonising fourth place!

5:59pm - Sailing

Here we go then, we're about to round the last mark, and then it's a drag race to the finish!

Australia are first - already guaranteed gold, Sweden second, New Zealand third.

But there's not enough boats between NZ and Spain.

5:57pm - Sailing

USA have moved ahead of Spain into fourth, before going past New Zealand into third!

This is going to be some finish!

5:56pm - Sailing

New Zealand are third around the mark, Spain have dropped back to fourth.

Australia and Sweden are still first and second.

5:53pm - Sailing

It's a four way shootout at the front of the fleet.

Australia, Sweden, Spain and New Zeaand are all in contention as we approach the third mark to begin the fourth leg.

5:49pm - Sailing

Coming up to the second mark. Australia are first around it, Sweden second Spain third.

It's close between New Zealand and USA into fourth. 

By our maths, New Zealand need to finish at least three places above Spain for bronze. The two teams are six points apart, so that would draw them level on points, but give NZ the bronze on countback.

5:44pm - Sailing

We're around the first mark. Sweden lead, followed by Australia.

Spain are third, USA fourth and NZ fifth.

At this rate, New Zealand will not win a medal.

5:41pm - Sailing

Sweden come roaring back and now they take the lead!

Spain have dropped to fourth, NZ fifth. 

We're still only on leg one of five.

5:39pm - Sailing

New Zealand take the lead on the first leg! They're battling it out with Spain at the front of the fleet.

Sweden are currently fifth.

Australia show their class and work their way into first. New Zealand are now second.

Still yet to round the first mark. There are five legs in this medal race.

5:36pm - Sailing

New Zealand are eighth at the moment. Spain and Sweden are second and third respectively.

The Kiwis will need to finish ahead of either if not both of those boats to have a chance at a medal.

5:35pm - Sailing

Japan look to have taken the early lead off the start line heading to the first mark, but the Spanish charge ahead. 

Still a very long way to go though!

5:33pm - Sailing

One minute until the start, the Kiwis are there or there abouts as the siren goes.

They're away!

5:30pm - Sailing

The crews are away in their pre-start. 

Three minutes before they get going.

5:20pm - Sailing

As things stand, the Kiwis are fourth heading into the medal race.

The Australian pair of Mathew Belcher and Will Ryan are guaranteed gold, while Sweden's Anton Dahlberg and Fredrik Bergstrom and Spain's Jordi Xammar and Nicolas Rodriguez Garcia Paz are second and third.

Wind conditions appear to be alright, and we should start at the scheduled time of 5:33pm!

4:55pm - Sailing

There's a bit of a break in the action for the Kiwi contingent in Tokyo.

But we'll be back at around 5:30pm, as the pair of Dan Willcox and Paul Snow-Hansen sail in the men's 470 medal race.

4:32pm - Golf

And Ko makes par on the 18th to finish. That sees her at one-under from her first round, tied for 13th at present, but still with more golfers to finish.

Sagstrom still leads at five-under through 13 holes.

4:25pm - Canoe sprint

That was a New Zealand record time from Brown and Imrie. 

They've booked their semi-final spot, to be around 1:30pm tomorrow.

4:21pm - Canoe sprint

This is going to be close! Belarus just pip the Kiwis to the line though!

Imrie and Brown settle for second, but they're still into the semi-final!

4:21pm - Canoe sprint

Belarus take the lead at 750m. The Kiwis will be in the semi at this rate, but will they want the win?

4:20pm - Canoe sprint

France have dropped off, this is now a four horse race, with the top three advancing.

Approaching halfway, and the Kiwis lead, but Belarus are right up there with them.

4:19pm - Canoe sprint

And it's another strong start for the Kiwis! Can they keep it going thought, as they lead at the 250m mark.

4:18pm - Canoe sprint

And they're off!

4:17pm - Canoe sprint

Brown and Imrie are up against Belarus, Italy, ROC and France in their quarter.

One minute until the start.

4:15pm - Canoe sprint

Max Brown and Kurtis Imrie are about to return to the canoe sprint for their K2 1000 quarter-final.

They'll need a top three finish to advance.

4:14pm - Golf

Ko pars the 17th, here's hoping she can finish her first round with one last birdie.

4:01pm - Golf

Ko makes par on 15 and 16, still in a 10-way tie for 12th place.

She has two holes left today to finish her first round.

3:50pm - Golf

A birdie on the 14th moves Ko up into a tie for 12th place.

The Rio silver medallist is now four shots back from a new leader, Sweden's Madelene Sagstrom.

3:23pm - Golf

Ko's made back-to-back pars on the 12th and 13th holes.

She's tied for 21st, four shots off the leading pair of USA's Nelly Korda and Chinese Taipe's Wei-Ling Hsu.

2:45pm - Golf

Back to the golf, where Lydia Ko has dropped down the leaderboard with a double-bogey on the 11th hole. 

It's seen her move to an even par on the back nine, now tied for 20th. 

2:25pm - Canoe sprint

Max Brown and Curtis Imrie have just finished fourth in their K2 1000 heat. They needed a top two finish to advance to the semi-finals, but will now compete in a quarter-final at 4:18pm today.

2:17pm - Canoe sprint

Carrington pulls away in the second half though, she cruises home for the win!

Germany's Sabrina Hering-Pradler takes second, Austria's Viktoria Schwarz is third.

All three advance to tomorrow's semi.

2:16pm - Canoe sprint

Carrington powers out in another huge start!

But she's got competition from Germany as we pass halfway. Austria third.

2:15pm - Canoe sprint

And they're off!

2:13pm - Canoe sprint

We're getting ready for the last heat of the K1 500. Can Lisa Carrington back up from her huge day yesterday?

She's in lane four, up against competitors from Samoa, Germany, Austria, Portugal and ROC.

2:07pm - Golf

Lydia Ko has finished her front nine with a blemish free two-under. The Kiwi is two shots off the leader, Chinese Taipe's Wei-Ling Hsu, who's four-under after five.

Ko is in a three-way tie for third.

2:01pm

There's about 15 minutes until Carrington hits the water for her heat, the last before the quarter-finals later today.

Hopefully Carrington won't need a quarter-final though, with the top three from each heat automatically advancing to the semis.

Just in case though, that quarter-final is at 3:50pm.

1:59pm - Canoe sprint

Regal can't hold her pace off the start line, but can she do enough for a top three finish?

She can. Sweden's Linnea Stensils takes the win, Australia's Wood is second.

Regal takes third and advances to the semi-finals.

1:58pm - Canoe sprint

And it's a great start from Regal! She leads at the 250m mark, but Australia's Alyce Wood is closing in.

1:57pm - Canoe sprint

Take two, heat three of the K1 500 lines up for the restart.

And now they're away.

1:54pm - Canoe sprint

And they're off! Or are they? Nope. False start.

1:52pm - Canoe sprint

Regal is in lane one, we're just about ready to start.

1:50pm - Canoe sprint

Regal's heat is nearly upon us.

She's up against competitors from Australia, France, ROC, Sweden, Algeria and Slovenia.

1:45pm - Golf 

Lydia Ko's birdied the eighth hole, and moved into a two-way tie for third!

The Kiwi is now a shot back from leader, and playing partner, Inbee Park.

1:38pm - Canoe sprint

Tuesday's gold medallists Lisa Carrington and Caitlin Regal are about to return to the water.

Both are competing in the K1 500, with the heats getting underway shortly.

Regal is up first in heat three, while Carrington is in heat six.

1:33pm - Golf

Birdie for Ko on the seventh! That moves her to one-under and a tie for fifth.

1:13pm - Golf

Korea's Inbee Park - playing in Ko's group - has taken an early outright lead through six holes in her defence of her Olympic title. She's currently three-under.

Ko is locked in an 18-way tie for ninth.

1:05pm

Just a reminder that we have Lisa Carrington back on the water at 2:15pm for her heat in the K1 500m canoe sprint. Just give her the gold already, right?

12:55pm - Golf

Steady start here for Ko, who putts in for her fifth consecutive par on hole five.

12:40pm - Golf

Another par for Ko, who's even through four holes. Tied for third early, still over half the field yet to begin their rounds.

12:18pm - Golf

Ko plays a deft approach shot on the third hole. Sets herself up for another par. She's currently tired for fifth.

12pm - Golf

Ko holes for par on the opening hole.

11:42am - Golf

Ko's group consists of Korea's Inbee Park - who's the defending Olympic champ - and China's Shanshan Feng, a very strong pack.

Ko sends one right down the middle off the first tee. Let's hope that's a sign of things to come.

11:35am - Golf

Morena, sports fans. Welcome to day 12, where Lydia Ko is preparing to tee off on the immaculate Kasumigaseki golf course.

***

Kia ora, good morning and welcome to Newshub's live coverage of the Tokyo Games, on a day when paddler Lisa Carrington begins her drive towards becoming the greatest Kiwi Olympian ever.

After capturing two gold medals on Tuesday - winning her third straight K1 200 crown and adding a K2 500 title with Caitlin Regal - Carrington will return to the water for K1 500 heats - an event where she won bronze five years ago at Rio.

She and Regal won't race for medals today, but the men's cycling pursuit team will, after smashing the world record on Tuesday night, yet still missing out to a rampant Italian foursome for the gold-medal race.

Aaron Gate, Campbell Stewart, Regan Gough and Jordan Kerby take on Australia for the bronze, after a chaotic night on the boards, where world champions Denmark and Rio gold medallists Great Britain crashed, sending the event into disarray.

After two hours' deliberating, officials eventually awarded their race to the Danes, who were on pace to regain their world record before the collided with a tiring British rider.

Elsewhere, Rio silver medallist Lydia Ko tees off in the women's golf strokeplay at the Kasumigaseki Country Club, hoping to recapture some of the form that has thrust her back into the top LPGA echelon over the past 18 months.

Sailors Paul Snow-Hansen and Daniel Wilcox are fourth, heading into the double-points medal race for 470s, while Commonwealth Games champion David Liti contests the +109kg weightlifting.

Kiwi Walsh needs 'Captain's Challenge' to qualify for shotput final

Kiwi shotput hope Tom Walsh had a nation's heart in its mouth, as he barely scraped through to an Olympic final where he's expected to challenge for gold.

The former world champion faced an automatic qualifying standard of 21.20m, a distance he has thrown hundreds of times in his career, but was dramatically called for three fouls - a situation which should have seen him drop out of the competition.

Circle officials ruled he had put his left foot over the circle rim on all his attempts, but Walsh successfully appealed the ruling twice - kind of a track and field 'captain's challenge' - to eventually record 21.49m and progress as the top thrower from his pool.

The Kiwi - and the rest of New Zealand - waited several tense minutes as officials reviewed and debated the call on his last and biggest effort, before eventually confirming he was safe.

"I'm not sure what the guy was calling," Walsh told Sky Sport. "I thought my first throw was fair and he called it a foul, when it was over the qualifying mark.

"On the second throw, I got a bit tight and a big pushy, and he called me a foul again. I thought 'hang on, what's going on here?'

"It's good to get it done - it's not the way I'd like it, but I had two good throws and I move on to the final."

Walsh insisted was calm and under control the whole time, even when he had to push his case again on the last throw.

"This is what I do and this is hat I do well," he said. "I stuck to what I know worked and it came off."

How much more does he have for the final?

"Plenty." 

Teammate Jacko Gill also left it until his last throw to progress to the final, managing 20.96m as the ninth qualifier.

American world recordholder Ryan Crouser needed only one toss to advance with 22.05m - the best of the qualifiers and the only thrower better than Walsh on the night.

American world champion Joe Kovacs, who edged both his rivals by a centimetre at Doha two years ago, snuck through with 20.93m, the second-to-last qualifier.

Meanwhile, hammer thrower Julia Ratcliffe finished ninth at her first Olympics, throwing 72.69m and actually leading for much of the opening round, before the favourites found their rhythm.
