A convicted sex offender who conned his way into schools to work with children learns his fate. And it's not enough time for a big pic to sort the catering, but a furious 48 hours lies ahead for these filmmakers. Good evening. A draft report leaked to ONE News reveals workers got sick from cleaning up NZ's most contaminated site. The document's due to be released next week. The report into the toxic area in Mapua, near Nelson, has been four years coming. Political reporter Jessica Mutch with the story. For decades, agricultural chemicals were made here. It later became the most toxic site in the country. In 2004, about 30 people worked to clean up the contamination, and they say it made them sick. Annette Walker has lived next door throughout it all and says it's been frustrating for the Mapua community. Here's my fence line, and as you can see, it rises up steeply, and underneath this mound here is still contaminated soil. A report from the Department of Labour is due to be released on Wednesday, the day before the Budget. But ONE News has obtained a draft that's been leaked to the Green Party. It shows four workers were studied for the report. All four staff's haelth deteriorated while they were working at the plant. Also, the longer they worked there, the more serious their health issues. The workers complained of health issues, including respiratory problems, nausea, collapsing and fatigue. All four workers were exposed to toxic chemicals because of inadequate protective equipment and dangerous work. This report is clear that people have got sick because of the site. This was one of the most toxic sites in NZ. Some locals were told not to comment to the media until it's officially released. We also tried to talk to the author of the report, who didn't want to comment until the community's been briefed. We tried to talk to the government agencies involved. They refused to talk on camera, simply saying they're already actioning some the recommendations from the report. Those recommendations include providing medical assessments and updating the Labour Department's health and safety guidelines. Jessica Mutch, ONE News. The judge in the Emily Longley murder trial has just sent the jury away to consider its verdict, asking jurors to deliver a unanimous verdict on all charges. Elliot Turner is accused of the teenager's murder, while his parents stand accused of attempting to pervert the course of justice. The judge completed her summing up of Elliot's evidence a short time ago, reminding jurors of the argument he had with Emily the night she died. She moved on to his parents' evidence, before asking the jury to retire. And our advice is that the verdicts are unlikely before the end of the day in England, with the jury then breaking for the weekend. Investigators hope to release the name tomorrow of a 77-year-old found dead in his Wanganui home, but they've confirmed his death was violent. Neighbours alerted police after noticing the front door of the man's house was left open yesterday morning. Police want to hear from anyone who may've seen the man's car or any discarded clothing in the area. There'll be a post-mortem examination tomorrow. A sex offender's been jailed for more than four years for using fake identities to get work in six different schools. Te Rito Henry Miki's case has sparked a review of the teacher vetting process to ensure more thorough background checks. Kate Lynch has the story. He lied, cheated and forged his way into the classrooms of hundreds of children for five years. Tonight Te Rito Henry Miki's past finally caught up with him I impose a sentence of imprisonment of four years, one month and two weeks. Miki's previous sex offences barred him from associating with children. So he exploited holes in the teacher-vetting system, forging degrees, lying on his CV and changing his name through a civil union partnership Had the vetting process required Miki to provide a copy of his birth certificate, which ONE News has obtained from Internal Affairs, it would have revealed all previous names he's used and his convictions would have been picked up in the police vetting process. We asked the Teachers Council to explain what documentation is required to stop applicants using a false name. Usually the identity is largely established through the academic qualifications. < So a birth certificate is not required ` is that what you're saying? No, it's not required. A ministerial inquiry into the case is due for completion next month. But the Education Minister says it's already evident the system needs reviewing. One of the things that the interim finding has made clear is that I am able to proceed with the review of the Teachers Council. The impact of this case has been felt in a number of communities where Miki taught and deceived. Malcolm Harding hired Miki to work with at-risk youth at Stratford Learning Centre. What possible harm did or could Te Rito have done to some of his students when I know they stayed with him and his male partner when I thought they were staying with him and his wife? An extensive investigation has so far found Miki has not reoffended. Kate Lynch, ONE News. A man (2) has been charged over the crash near Turangi which killed three young American tourists. Stephen Houseman was driving the people mover which rolled on a bend on State Highway 46 on Saturday. The US citizen's been charged with three counts of careless driving causing death and four counts of careless driving causing injury. Police have ruled out any use of drugs or alcohol by the passengers or driver. A woman (21) remains in a critical condition in hospital. The mother at the centre of the 'accidental millionaire' case says she's relieved despite being convicted on 30 charges. Three years after Kara Hurring fled to China, she's been found guilty of theft, dishonesty and money laundering. Ruth Wynn-Williams has been at the trial in Rotorua. She spent two years on the run, but today Kara Hurring couldn't avoid the spotlight. It took a Rotorua jury less than an hour to decide the mother of two is to blame for her part in the alleged theft of $10m after a Westpac banking error in April 2009. Do you find the accused guilty or not guilty on count 28? < Guilty. Do you find the accused guilty or not guilty on count 29? < Guilty. In all, 30 guilty verdicts, 25 of those for the theft of around $11,000. These relate to purchases and withdrawals made using then-partner Leo Gao's EFTPOS card for four days' shopping in Auckland before she left for China. The jury also found Hurring had been dishonest in the way she used that EFTPOS card, repeatedly taking it to its daily limit. But its the final two charges that carried the most weight ` laundering money through a casino in Macau for Leo Gao. The verdicts brought mixed d The verdicts brought mixed 8 She wasn't the runaway millionaire. Not one cent of Westpac money went into her bank accounts. Leo Gao, the man whose account it allegedly did go into, is in Auckland awaiting trial. He faces 17 charges of theft and 10 of money laundering. He's not allowed to associate with Hurring. She too remains on bail, and will be back in court on August the 24th. She'll be sentenced on a lesser basis than, for example, Mr Gao, because the amounts of money she's said to be involved in are obviously significantly less. And the prosecution's had this to say about the banking error which sparked an international man hunt. Pretty unique. (CHUCKLES) To say the least. I can't wait to see my kids. One thing no amount of money can buy. Ruth Wynn-Williams, ONE News. Councillors who've called for an immediate halt to demolition of the Christchurch Cathedral are being accused of trying to placate the masses. Earthquake Minister Gerry Brownlee says the decision of 10 of Christchurch's 14 councillors to vote for a pause in the cathedral's deconstruction does no good for the city. The Anglican Church is also questioning the motives of the councillors. What we are now dealing with is reputation politics and not about the cathedral. The Church needs to focus on the cathedral. The Bishop says the majority of Christchurch people believe the cathedral needs to come down. Police are warning motorists to take more care on rural roads after cows were hit and killed in two separate incidents tonight. Between 6.30 and 7 this evening, two motorists collided with cows ` the first near Hunterville, and the second near Clareville in the Wairarapa. Both drivers were in shock but unhurt. Police say they had to put one cow down. The other had died at the scene. Just ahead ` it's tipped as the biggest tech share float ever, but should Facebook's status read over-valued? The A to Z of all creatures great and small. A Wellington catalogue marks a world first. And what some frantic filmmakers will be doing for the next 48 hours. 1 Investors around the world are waiting to see what's going to happen in a few hours when the world's largest social networking site goes public. Facebook begins trading on the NASDAQ stock market at around $50 a share, bringing the company's value to almost $137b. But investors are warned to take care. We're telling our investors to hold off. Number one, we don't know what the guts and the balance sheet of the company looks like yet. So that's a big red flag for us. We want to understand the business before we tell people to invest. Some analysts say the opening price may double or even triple within a few hours of floating. Doctors in Australia are calling for everyone over the age of 50 to be given cholesterol-lowering drugs. They say the blanket approach will have major health benefits. But others aren't convinced. The ABC's Tracy Vo reports. It's the biggest-selling drug in the world and a powerful weapon against heart disease. Grandmother Morag O'Gorman is one of 2 million Australians taking statins. I did have a high cholesterol count. It was very high. And, um, it had to come down. It's handed out only to those who have, or are at high risk of, heart disease. Australian and British researchers now say all low-risk patients over the age of 50 would benefit. This research presents a new paradigm in terms of how broadly statins should be offered. Studies show that if 1000 low-risk patients took the drug for 5 years, it would prevent 11 cardiovascular emergencies in the future. Some cardiologists are worried. It sends a message out there that drugs are more important than lifestyle. When the liver produces too much cholesterol, it can clog the arteries, leading to heart disease and stroke. Statins stabilise the liver, but the side effects include muscle pain, stomach problems and liver damage. It can also increase the risk of diabetes, and memory loss. I get all these joint pains, and I get, um, a lot of trouble` I have a lot of trouble with my liver. Anyone who's prescribed them is told it's not a substitute for a healthy lifestyle. The best drug on the planet ` happiness, peace and contentment. A Wellington scientist has published a gigantic catalogue of all the plant and animal species that have ever lived in NZ. We're the world's first country to compile such a history of our biodiversity, and as Renee Graham reports, there are some surprising findings. For 12 years NIWA scientist Dennis Gordon's been documenting all of the native animals, plants, fungi and microorganisms in NZ dating back 530 million years. If you want to know the origin of the living fauna and flora, you need to know what came before. The marine biologist says NZ's been host to about 71,000 different species. He's catalogued them all in a three volume series The NZ Inventory of Biodiversity. The inventory documents all of the species that have ever lived in NZ throughout all of time. That includes more than 56,000 living species, as well as almost 15,000 fossil species. No other country has a complete record like this. That includes more than 56,000 living species, as well as almost 15,000 fossil species. No other country has a complete record like this. Almost 250 scientists from around the world helped make new discoveries. Europe has an area 5� times the size of our exclusive economic zone, but only twice as many marine species, so what that tells us is that on a proportional basis we're actually quite rich. NIWA says it's invaluable. Laboratories, public libraries and schools will use it, as well as government departments like the Environmental Risk Management Authority. Knowing what we have and how rare they are or how abundant they are is just the absolute underpinning knowledge you'll need to have if you're going to come up with, say, conservation strategies. Dennis Gordon is certain he's surveyed 99.9% of all NZ species that have ever existed. But it's only a snapshot in time, because every day new species are discovered or others become extinct. Renee Graham, ONE News. A past winner is behind NZ's most successful movie, so there is plenty for some very busy filmmakers to live up to, starting tonight. The 48 Hour Film Festival is underway. It gives filmmakers until Sunday to plan, shoot and edit a film. Wilhelmina Shrimpton reports. ALL: Four, three, two... Ready, set... action! They've got just two days to script, shoot and edit a movie, but there's a catch. There's a character we give them which can be anyone in the film, a line of dialogue and a prop, and there's usually a special kind of camera movement as well that we throw in just to mix things up, just so people can't prepare in advance. This year's lot must include an element of slow motion, a prop in the form of a leaf, an unlucky character called Nicky Brick, and the line 'I did that' as part of their short film. They're also given one of 12 genres, including horror, romantic comedy and fantasy adventure. We got superhero. Are you happy with it? > Yeah, I've done something similar before, so lots of capes, lots of jumping off buildings. Should be a lot of fun! Yeah, we're really excited. Yeah, we're really excited. We should do all right, actually. We got one continuous shot of all the other genres and I'm effectively a one-man team. Yeah, I'm in trouble. 755 teams will take part in this year's competition, but it's not all fun and games, with a cut-throat race to the finish line at 7 o'clock on Sunday evening, with some previous years' teams having missed out on the deadline by just seconds. The competition's in its 10th year, setting many film-makers on the road to success, including 'Boy' director Taika Waititi, whose 'Heinous Crimes' took out the Wellington 48-hour title back in 2004. It's very much a talent incubator of the next generation of film-makers that have come through, so for spotters of who's going to be the next big star, I think it is a very important event now. The best films from each region this weekend go to the grand finals for judging next month. Wilhelmina Shrimpton, ONE News. Just ahead ` the Brumbies break their dry spell in a sodden capital. And her music sound-tracked the disco era ` the world says goodbye to Donna Summer. And all your weekend weather right after the break. Now to the most viewed stories on our website today ` Some Christchurch homeowners are confused at the government's decision to include their homes in the red zone. The Police Association fears 'serious consequences' after 125 support staff are cut from the payroll. And three of the Wiggles are passing on their skivvies to the next generation. The Brumbies have broken their Super Rugby drought in wet conditions in Wellington tonight. Home side the Hurricanes started well, taking a half-time lead thanks to Perenara and Vito linking off the back of an attacking scrum, leaving Vito to run off the shoulder of Tim Bateman. So, in it goes from Perenara. Now Vito, off to Perenara. Coming on all sorts of angles! And Victor Vito, from a set move, scores under the posts. Then with under 20 minutes to full time, a careless error from the Hurricanes at the scrum cost them the lead. here's an opportunity for the Brumbies. Flanker Michael Hooper was the scorer. So the Brumbies won 37-25 and take a valuable bonus point too. The Warriors are off to a solid start in their difficult away assignment at Wests Tigers. A Shaun Johnson dummy set up the Warriors' opening try after just four minutes. They're not going to stop them! And going in to score is Tupou. Next, James Maloney hoisted a high ball, Manu Vatuvei put pressure on Beau Ryan, and in the confusion, Henry got the score. The half-time score ` Warriors 10, Wests Tigers 0. Weather time now with Renee. The cold south-west flow weakens tomorrow as this high pressure spreads over the South Island. This trio of fronts closes in on us, with the leading warm one making landfall late in the afternoon. This mess continues to move away in the Pacific. For weather, see tvnz.co.nz And that's your weather. Have a great weekend. Singing royalty is tonight applauding the disco diva who got a generation hitting the dance floor. The death of Donna Summer has Liza Minnelli saying we'll dance to her music forever, while Gloria Gaynor says heaven will be dancing with joy at Summer's arrival. This from the BBC's David Sillito. DONNA SUMMER'S 'I FEEL LOVE' PLAYS # Ooh. # It's so good, it's so good, it's so good, it's so good... That sound ` the pulsing electro beat, Donna Summer's soaring voice. This was, in 1977, the sound of the future. # Ooh. # She started off defining an era. Then with the track I Feel Love, she elevated disco into high-energy and then onwards, which of course now, you know, is the daddy of today's modern dance music. So she was so influential. Donna Summer learnt to sing in a gospel choir. But they didn't teach her this. # Oh, love to love you, baby. She had met the music producer Giorgio Moroder while living in Germany. It was a sound she later regretted. # Oh, love to love you, baby. # I was tired of the whole sex image, because it wasn't me, and it was something I was playing. It was a role. But it wasn't who I was as a person. And I always resented it. In the '80s, she found God and lost many of her fans ` especially her many gay fans. Alleged comments about HIV ` comments that she later denied ` were career poison. # Let's dance the last dance... 29 Top-40 hits, and the song that changed the world's dance floors. Donna Summer, the queen of disco. # Let's dance the last dance. # Come on, people, now. # Get out of your chairs. # Let's dance the last dance... # tonight. # 'Last Dance' was in the NZ charts for 14 weeks in 1978. Summer was 63 and died of cancer. That's it from us here on Tonight. And you can stay up to date by logging on to our website at tvnz.co.nz Thanks for watching. Goodnight.
