Due to the live nature of Tonight, we apologise for the lack of captions for some items. Tonight, the Urewera Four finally appear in court but deny running military-style camps. Athens ablaze. The latest austerity measures have Greeks up in arms and on the streets. And Whitney's daughter is rushed to hospital as the Grammies pay tribute to the late singer. 17 were originally accused. Now four years on, the trial of four people charged after the Urewera raids is about to begin. All four, including well-known activist Tame Iti, have pleaded not guilty. They're accused of possessing guns and participating in military-style camps. The trial comes after a long-running legal battle which resulted in charges against others being dropped. Donna-Marie Lever's been in court. It's been just over four years since their arrest, but the final four accused will have to wait one more day before the case against them is revealed, a case they all plan to fight. Innocent before charges. Tame Iti, Emily Bailey, Urs Signer and Te Rangi-Kaiwhiria Kemara all face firearms charges and allegations of participating in an organised criminal group. We're here to dispel the illusion, that's the case that's been put by the Crown, so I leave the matter to the court to deal with it. I leave it to my legal council. APPLAUSE 13 others had their charges dropped last year after the Supreme Court ruled the video surveillance obtained by police was unlawful and therefore cannot be used as evidence. Because the other four face more serious charges, the court ruled it can be used against them. Another man, Tuhoe Labert, died in July last year awaiting trial. Outside court today, Tuhoe supporters still want to see all charges dropped. The trial should never have started. In reality, the trial should never have started. That's the point I'm trying to make. The case has been bounced between every court in the country ` from the District and High Courts to the Court of Appeal and Supreme Court at a cost of millions. The case was to be heard by a judge alone, but the accused wanted a jury, so they went to yet another court and won. Now much of day one has been spent finding a jury that can commit to the three-month timeframe that the trial's set down for. While it's not expected to take that long, some complex issues will be raised. Some 88 Crown witnesses alone will be called. The four accused will also have a chance to put their own cases forward, but first the Crown will begin with its evidence tomorrow. Health authorities have admitted to overreacting to a health scare at Auckland Airport, but say it's better to be safe than sorry. They swung into action after it was suspected dozens of Japanese students, who'd just landed, had contracted the flu. Stephen Smith was at the airport as the drama unfolded. While ambulance staff were ready for the worst, the students at the centre of this scare came through the arrival gates wondering just what all the fuss was about. Their flight, NZ90 from Tokyo, halted on the tarmac just after 9 this morning. 73 of the Japanese homestay students onboard were suspected of carrying an unknown strain of influenza. There were air staff everywhere all wearing masks, just sort of shepherding us to different places. Passengers like David Turner left wondering why authorities took two hours to board the plane, when they were told two hours before landing there was an issue. It was just confusion. Nobody knew what was happening. One person was doing one test on one person, and the other person was not doing the pulse, but only the ear thing. The left hand didn't know what the right hand was doing. It was a disaster. It does take time, and I know that can be frustrating, but it's important to get it right. I've spoken with one of the men organising this homestay trip. He understands only a few of the students showed visible flu-like symptoms, and from that, another passenger raised the alarm. The whole group actually were vaccined back in November, leading into the Japanese winter. There's no influenza; there's no flu; and that's been the official word from the authorities. The diagnosis ` a few boys had mild viral illnesses, little more than the common cold. In hindsight, we overreacted to this, but that's much better than underreacting. Four hours after landing, the largely healthy students left for Tauranga, an eventful start to their 10-day NZ holiday. Across the Tasman, hail and thunderstorms have battered parts of Sydney and the Blue Mountains. Hailstones filled gutters and blanketed backyards. In Katoomba, the sports and aquatic centre had to be closed after the weight of the hail caused part of the roof to collapse. Eight canyoners had to be rescued at Wentworth Falls after flash floods trapped the group in a narrow gorge. And lightening hit this house in Castle Hill, in Sydney's north-west, starting a fire in an air-conditioning unit. The streets of Athens are ablaze as Greeks vent their anger over a harsh new round of spending cuts. The government's voted for austerity measures as it tries to save the debt-crippled nation from bankruptcy. But the unpopular move's sparked some of the worst demonstrations in the capital, Athens, in years. This from Channel Nine's Mark Burrows. Buildings on fire across the city. Protesters exploding with rage on the streets as Greek politicians pass new laws slashing spending. BOOM! At least 10 buildings were set alight. A furious reaction to the laws which will see pensions and the minimum wage cut. 150,000 public service jobs will go. Earlier, 100,000 swarmed around the parliament. Many are facing years of hardship. Half of all young Greeks are jobless. Around Greece's main square, there were running battles. The way is now clear for Greece's Euro partners and the International Monetary Fund to come to the rescue with $160 billion bail out. (SPEAKS GREEK) TRANSLATOR: Everyone must realise that the dilemma is whether we will save the country with great sacrifices or if we will march supposedly proudly towards catastrophe. Austerity might be in the winds, but right now it's tear gas that's in the air as Greece wrestles with a bleak future. The presence of Whitney Houston formed a powerful backdrop to this year's Grammy Awards with many performers dedicating the night to her memory. It's now thought the singer (48) may have drowned in a hotel bathtub. Foul play is not suspected. She had just 24 hours' notice, but singer Jennifer Hudson pulled off a spectacular tribute to her childhood idol at the Grammys. # I will always love you. I will always love you. # The spirit of Whitney Houston dominated the event. The only thing that feels right is to begin with a prayer for a woman who we loved, for our fallen sister, Whitney Houston. Many artists voiced their love for the singer. When the truly great artists leave us, their legacy lives on. We love Whitney Houston. I just want to say to Whitney up in heaven, we all love you, Whitney Houston. Meanwhile, investigators continued to try and find out what killed Whitney Houston. New reports have emerged that she was found submerged in a bathtub, with a number of pill bottles in her room. There will be no cause of death at this time because it is pending toxicology. Her daughter Bobbi Kristina (18) was unable to cope, and was admitted into hospital today for severe anxiety. But as they say, the show must go on. The Grammys were dominated by British singer Adele, grabbing six awards, including song of the year, and album of the year. And the Grammy goes to 21, Adele. The soul singer topping off her special night with her first live performance since undergoing throat surgery last year. # We could of had it all... # Another big winner were American rockers the Foo Fighters, picking up five awards for their album Wasting Light. But the night kept returning to a fallen star. # Whitney, we love you. We love you. # A man's been charged in relation to the car crash that killed high-profile Timaru businessman Alan Hubbard. A car driven by Mr Hubbard's wife, Jean, collided with another vehicle north of Oamaru last year. Mrs Hubbard was injured in the crash. A 40-year-old's been charged with careless driving causing death and injury. He'll appear in a Dunedin court on Friday. Dunedin fire crews have been busy tonight with a blaze at a city hotel. The fire broke out in a room on the third floor at the Kingsgate Hotel around 8.30. Inititally we had five persons reported missing, and we're since certain that they're probably out having dinner somewhere else. The building's been searched and cleared. Crews will continue to check ventilation shafts in the building for signs of fire through the night. Now to the bizarre tale of a Nzer who's stowed away on board an unauthorised expedition to Antarctica. Aucklander Busby Noble's now only days away from Antarctica after falling asleep on board a ship. This is all that's ever been found of the vessel on the ill-fated Antarctic trip last year ` an empty life raft, three men dead. Now exactly a year on, the captain has a new boat and a stowaway ` Otara man Busby Noble. I was asleep in the front of the boat, and the captain who was being deported, he didn't know I was up there. This is the first time Busby Noble's spoken to media. We reached him via satellite phone. I did not want to be on the trip. I didn't want to be in these conditions. I don't see how anybody else would want to either. Busby Noble joined the trip in Auckland last month. The vessel's now close to its destination ` McMurdo Sound. The trip is unauthorised and has caused a stir internationally, because it's led by the same man who was in charge of the deadly trip last year, Norwegian Jarle Andhoy. He wants to find anything left behind. Some call him crazy. He seems unfazed by that. I think people can judge as they want. The most important thing for me on this expedition is to find out what happened. Jarle Andhoy may find himself in trouble with our authorities for failing to submit paperwork. He could face a fine of up to $100,000. The Ministry of Foreign affairs tell us that officials are still considering legal options, but that penalty could potentially be applied to every member of the crew. It's hoped this expedition won't be a repeat of last year's disaster. Just ahead ` more damning evidence is heard at the inquiry into the Pike River Mine disaster. Could reducing what you eat help improve your memory? And the stars come out to play at the British version of the Academy Awards. 1 An Australian mining expert believes the Pike River coal company didn't fully understand the problems it faced with its underground electrical system. Today the Royal Commission's heard that inability to remedy those issues may have triggered the deadly blast that killed 29 miners. Pike River survivor Daniel Rockhouse fleeing the mine. One of his strongest memories underground was seeing a white flash. Today a highly technical explanation of what probably caused that flash ` a chain of events that released a stray current into the electrical system capable of causing sparks in the volatile mine. It would basically light up the entire system like a Christmas tree. He says a pump, switched on just before the explosion, probably acted as a trigger to ignite methane in the mine. There was a very close coincidence between the pumps starting and the flash appearing. Proof of his theory is this methane detector at the top of the main ventilation shaft. He says it shows scorching from electrical sparking. It's just not acceptable under any circumstances. But he told the commission Pike River knew it had problems with its electrics and the mine should have shut down until it was resolved. There was quite a degree of confusion in my view as to what was causing all of this. However, Rockwell Automation, which installed parts of the system, says Mr Reczek's evidence is... The families say the only way to find out for sure is to go into the mine. It's all hearsay. We still haven't got rock bottom answers here. He says their lawyers are writing to the Commission to ensure that happens. The icy weather gripping Europe is continuing to claim lives. In Romania, more than 68 people have died in fierce winds and snow, while in Italy, at least 40 homeless and elderly people have been killed in the cold snap. Montenegro has declared a state of emergency as snow blocks roads and railways, while in Bosnia, the roof of an Olympic ice skating rink has collapsed, but luckily, nobody was inside at the time. And there's been a miraculous rescue in Kosovo, where a 5-year-old girl has been pulled out alive after being trapped for more than 10 hours under a massive avalanche. She was discovered when rescuers heard her voice and ringing cellphone. The girl's parents and at least seven other relatives were killed after 10m of snow flattened several houses. Some food for thought now, as we age. A new study has found that if you put less food on your dinner plate, you are likely to remember more tomorrow. Deborah Roberts from America's ABC has the details. It's one of our worst fears ` losing our memory. The early stages are often clear. Significant forgetfulness for recent events and future engagements. Misplacing key, things like that, does not count. There's already a known link between reducing calories and preserving memory, so Mayo researchers wondered, 'Do extra calories consumed over the course of a day worsen memory?' In their study released tonight, more than 1000 volunteers aged 70 and older, with no signs of Alzheimer's, reported what they ate and drank. The top third took in more than 2100 calories a day. The lower third, 600 to just over 1500 calories a day. The results? Astonishing. The higher the daily caloric intake, the higher the risk. They found that the... ...compared with people eating less. By consuming fewer calories, the body doesn't have to produce as much insulin. When there's less insulin, brain cells communicate better. At a time when there's no proven medicine to help preserve our memory, we now know that simple lifestyle changes may offer the best protection to hold on to what we have. The study also found that people who lost weight found their memory improved. Just ahead ` Renee's here with thundery falls for some. And we'll leave you with Adele's comeback performance at the Grammys. # The scars of your love, # they leave me breathless. # I can't help feeling # we could have had it all. # You're gonna wish you... French silent film The Artist has swept the British Film and Television Awards, taking Best Film, Best Director and Best Actor. Meryl Streep claimed best actress for her role as Margaret Thatcher in The Iron Lady. The BBC's Will Gompertz has highlights from the Baftas. As evening falls, the stars come out, brightening up London's chilly Covent Garden. PHOTOGRAPHERS SHOUT INDISTINCTLY, CAMERAS CLICK The British film industry is all dressed up for its big night out. JAUNTY MUSIC Last year, it was The King's Speech which swept the board. This year, it was a French film with no speech. And the Bafta for Best Film goes to The Artist. CROWD CHEERS, CLAPS And the Bafta goes to... Michel Hazanavicius. CROWD CHEERS, CLAPS Thank you again. I'm... I'm so proud. And the Bafta goes to... Jean Dujardin for The Artist. CROWD CHEERS, CLAPS And as Buster Keaton would say... CROWD LAUGHS Thank you. Thank you very much. It even won the Best Screenplay. Actually, I'm very surprised, because... so many people thought there was no script, because there was no dialogue. CROWD CHUCKLES And so English people are very clever. CROWD LAUGHS Congratulation to you. When it came to the battle of the blondes, Michelle Williams' Marilyn lost out to Meryl Streep's Margaret, who then lost her shoe. Colin Firth, a king last year, was a Prince Charming tonight. CROWD CLAPS Half of me is Streep; but the other half is Wilkinson from Lincolnshire. So I come by it honestly, this part. Thank you very very much. I'm so grateful. We now move on to the grand finale of the awards season and the Oscars in a fortnight's time, where all the talk will be of The Artist repeating its Baftas sweep. '20s-STYLE JAUNTY MUSIC Hi, everyone. The low pressure over the Tasman Sea seems to bump into the South Island tomorrow, becoming slow-moving as it pushes up against the ridge. However, it's associated frontal system continues eastwards. That weak surface trough and showers drifts across the Bay of Plenty tonight then off the north-east tomorrow. Warm and moist air that's been trapped along the east of the country gets more organised forming into a front during the early morning. For weather, see tvnz.co.NZ And that's your weather. I'll see you tomorrow. That's almost it from us here on Tonight. We'll leave you now with Adele and her Grammys performance of Rolling in the Deep. The singer won four awards, including, of course, Song of the Year. Thanks for watching. Goodnight. # There's a fire starting in my heart, # reaching a fever pitch, and it's bringing me out the dark. # Finally, I can see you crystal clear. # Go ahead and sell me out, and I'll lay your stuff bare. # See how I'll leave with every piece of you. # Don't underestimate the things that I will do. # There's a fire starting in my heart, # reaching a fever pitch, and it's bringing me out the dark. # The scars of your love, # remind me of us. # They keep me thinking # that we almost had it all. # The scars of your love, # they leave me breathless. # I can't help feeling # we could have had it all. # You're gonna wish you # never had met me. # Rolling in the deep. # Tears are gonna fall. # Rolling in the deep. # You had my heart and soul... # You're gonna wish you...
