Tonight ` the lead-up to the government's much-maligned deal for a new convention centre is to be formally investigated. More ACC fallout as another top-level manager walks ` now critics are calling for the minister's scalp. And if you think a tan in a can is without risk, think again. A turbulent time for John Key's government has just hit another big bump. Political editor Corin Dann has developments. John Key has made getting a national convention centre for Auckland one of his pet projects, and he refuses to see today's inquiry by the auditor general's office as a setback. Absolutely appropriate that they have a look at it. As I say, I think it is a great thing. I welcome it. The Greens called for an inquiry. They allege the government's expression of interest process was unfair and stacked in Sky City's favour. They've been dodgy in the way that they've approached this deal, and I think the auditor general will be able to answer the questions that the public has about whether this deal was the right thing to do. Labour, meanwhile, says the inquiry strikes at the heart of the Prime Minister's credibility. He's the person who took the took the Sky City deal forward. He's the person who stopped the business case. He the person that had talks behind closed doors. He's the person who staked his credibility around it. It's a shonky deal, and they should stop it. But John Key says he's done everything by the book. You met with the Sky City board in 2009, and then the expressions of interest are by Cabinet in 2010. That's not a great look, is it? Well, there has been nothing unusual about that. We asked a whole lot of people to tender, and I met with a number of players, not just Sky City. The government and Sky City are still negotiating the terms of the convention-centre deal. John Key says he sees no reason why that can't go ahead, even with an inquiry. ACC's revealed to ONE News tonight it's spent almost $90,000 in the last 18 months on extra help for its public relations and media management. It comes as the opposition slams ACC, saying it's in utter chaos after another resignation, this time its chief executive. Here's political reporter Jessica Mutch. The ACC Minister facing questions once again. In the past 24 hours she's lost the ACC chairman. Now the chief executive's gone too. I simply said to Mr Stewart, was he sure of that decision. And he was. And I actually feel quite sorry for Mr Stewart ` he's had a tough time. He's only been in the job for eight months ` what reasons did he give you for his resignation? He said he felt it was time to move on. Ralph Stewart refused to comment on camera, but he did issue a statement to staff saying this has been an incredibly tough decision and he's deeply frustrated that ACC's work has been overshadowed by this saga. But he did apologise in an exclusive interview with ONE News last month. And I would just like to apologise on behalf of ACC to all the clients of ACC's. Labour says ACC is in utter chaos. ACC is in the deepest crisis it has been in its 38 years of existence. ACC looks after us when we have an accident, but it's now suffering its own casualties. Today Ralph Stewart is gone, yesterday it was chairman John Judge, and two other board members will also be replaced. And don't forget in March Nick Smith was stood down from his ministerial portfolio. Labour says Judith Collins should be next. Her board has deserted her, the senior management has deserted her ` it's time that she went. It actually has to stop, this silly nonsense from Mr Little. In another twist, Labour says ACC has shelled out big bucks to a PR company to help them handle this saga. Tonight ACC confirmed they've paid out $89,000 to Acumen Republic at the beginning of last year. That is just unforgiveable from an organisation that is set up to look after people who are injured. There's more to come on this story - two high-powered investigations into ACC are due back in the next couple of months. Jessica Mutch, ONE News. A lawyer who specialises in ACC cases says the saga could benefit its clients. Hazel Armstrong says continuing pressure on the corporation could make staff more vigilant and speedy when assessing claims. I think maybe that all of this spotlight on them might make them more rigorous in how they investigate claims and make decisions, so this is a good thing. There've been the first signs of emotion from the man accused of Scott Guy's murder. It came late this afternoon, as Ewen Macdonald's wife talked about his relationship with the Feilding farmer. Simon Bradwell has the latest from the High Court in Wellington. It was this exchange between his lawyer and his wife that caused Ewen Macdonald to break down. < Mrs Macdonald,... < on the 7th of July 2010, had your life ever been more perfect? No. < You were positive about the future? Yes. We're not allowed to show you, but at that point Ewen Macdonald broke into loud sobs, wiping his eyes with a handkerchief. July the 7th is the night before Scott Guy's death. Anna Macdonald also struggling with tears as she accepted that at that point, she hadn't known Ewen Macdonald had set fire to a property of her brother's or illegally hunted deer. Earlier, she said her husband was competitive with Scott Guy over money. We thought Scott that was being paid more, but yet Ewen was doing the longer hours. And annoyed over her brother's treatment of stock. I think he had a couple die. Kylee Guy, the names of her two sons and dead husband on her wrist, agreed Scott Guy and Ewen Macdonald didn't communicate well. Obviously, I didn't know Ewen much, and obviously he really didn't talk much and had a kind of an odd personality. Despite living close to each other, the men's relationship was strictly professional. Not once since we moved to Feilding, he's never been around for a coffee or say just to say hi. In his evidence, Scott Guy's father, Bryan, acknowledged Ewen Macdonald was a good worker who deserved much of the credit for the farm winning awards for its milk quality and was equally successful as a keen hunter. He would bring home some of the stags' heads and have them` and there was three or four that he get mounted and actually had in the lounge. Deer he shot during night-time trips he called 'missions'. Simon Bradwell, ONE News. A woman held captive in rugged bush for 38 hours by her jealous ex-boyfriend is still haunted by her terrifying ordeal. Police are calling her a hero after Nathan Boulter was jailed eight and a half years for the kidnapping on Great Barrier Island, near Auckland. Donna-Marie Lever was in court. (SOBS) Nortessa Montgomerie doesn't want you see her tears, but she's still determined to tell her story of a horror 38-hour ordeal as a hostage. My whole body was covered in blood. I thought I was going to die. She was repeatedly beaten and strangled at the hands of her ex-boyfriend Nathan Boulter, who kidnapped her on Great Barrier Island last year. I'm so happy. Multiple blows to the head caused haemorrhaging and a brain bleed. Her hair was ripped from her scalp. But the psychological scars run much deeper. If someone arrives at my house in the evening or the phone rings, I just freak out and hide. I refuse to answer the door if I'm alone. The incident sparked a massive armed police response on the island. Nortessa Montgomerie's boyfriend was also attacked and knocked unconscious, but police say she did everything right to survive and should be held up as a hero to other women. Her decision-making under distress at that time when her survival instincts kicked in are a real inspiration to women out there. Just amazing. But her family feel let down by the eight-and-half-year sentence. Well, our whole family, we're gutted. You know, just not long enough for someone that does that sort of crime. The court heard of Nathan Boulter's troubled childhood, his substance abuse and underlying psychotic illness. But did that illness play a part in his offending? I am prepared to accept some link between the historical nature of your diagnosed disorder and your offending. The judge choosing not to hand out a minimum non-parole period as an incentive for Boulter to rid himself of his demons. Donna-Marie Lever, ONE News. The American student behind the wheel of a van that careered off a road and killed three other students has been convicted and discharged in court. Stephen Houseman (20) pleaded guilty to all charges, but his lawyer, friends, family and supporters still asked for discharge without conviction. Speed and alcohol were not factors in the accident. This is genuine remorse, not just for himself, but obviously, he recognises the terrible pain and lifelong pain for those who lost their children. The judge says he is, however, guilty of careless driving and disqualified him from driving for six months. The only other survivor, Meg Theriault, left Waikato Hospital today on a mediflight bound for Boston, in the USA. Her parents tonight left an emotional statement. We're just overwhelmed with the appreciation and the kindness of all the people. We will be back to, you know, show our appreciation again. Meg has a lot of people she... she needs to thank. (SOBS) Thanks again. Her parents say she'll be back to visit the Tongariro Crossing when she's recovered. A ONE News exclusive now on people being duped into fake permanent residency in NZ. Community leaders want urgent government action, saying thousands of Tongans are affected. Pacific correspondent Barbara Dreaver's been investigating. Whoever stays will get their permanent residence. But who do you work for? > It's none of your business. Fetongi Malupo had been selling NZ residencies. Tongans in their droves have handed over their passports and $290, but have got nothing so far. I asked him, 'Can we have a receipt from the money you take from the passport?' And he said, 'No, we don't have a receipt here.' The residency-selling group has targeted kava groups, South Auckland churches and also travelled to Tonga to lure in people. I would say between 3000 and 5000, and I'm not just talking about Auckland alone. The group claims to have a contract with the NZ government. If you don't have a visa from Immigration NZ, it's not a legitimate one, and if it's been secured by paying money, then that's just a scam. ONE News tracked down Mr Malupo, who was at his Mangere office. I did it. I want to help my people. But you must have known it was a scam. With the money, the amount involved, I think it was worth taking a risk. And if it doesn't work, it doesn't work. He says he only collected the money and passports, which he gave to fellow Tongan Kolini Tatafu. In 2004 we uncovered a pensioner-housing scam she was running. We wanted to ask her about her role in this immigration scheme, but she proved as elusive today as she did back then. How dare them rip these people off? Mr Malupo is promising to return money and passports to anyone who wants them. Immigration NZ is taking a keen interest in this case. Barbara Dreaver, ONE News. Victory for the 700,000 NZers who are Deaf or have impaired hearing. NZ On Air and TVNZ have agreed to work with production company South Pacific Pictures to ensure their DVDs have English subtitles. This will include shows like Go Girls. What it means is that the Deaf community now have access to their culture ` NZ DVDs ` which everyone else has access to, so that's a fantastic outcome. The announcement follows a ONE News investigation which looked at why the majority of Kiwi-made DVDs have no subtitles despite being funded with taxpayer dollars. Just ahead ` a gloomy prediction about economic times for the next decade. Also ` free dental care for those feeling pain in the pocket. And if you think spray tans are a safe way to get that golden glow, new research may change your mind. The Kathmandu winter sale starts Thursday, with up to 60% off a massive range. There's huge savings on fleece, thermals, down jackets, rainwear, packs and much more. Don't miss the Kathmandu winter sale. It starts Thursday. 1 And gloomy news from the boss of the Treasury, which advises the government on financial issues ` we're facing turbulent economic times for the next decade. Gabriel Makhlouf told MPs that problems in the European economy won't be easily fixed and that will have a long-lasting impact on NZ via our major trading partners, Australia and China. I think we're entering a world or have entered a world where this sort of uncertainty and fragility of the world economy is probably going to carry on for another five to 10 years. Reserve Bank governor Alan Bollard will give his opinion on the global outlook tomorrow. The country's first charity dental clinic has opened its doors in Christchurch offering free care to patients who can't afford to visit a dentist. It's the latest offering from the city's five-year-old charity hospital. Health reporter Lorelei Mason has the story. A week of nagging pains led Maree Carson through these doors. Hello, I'm Maree Carson. She has an abscessed tooth which she can't afford to get fixed. For a root canal, it's normally $600. You think, 'Oh no, how am I gonna afford to get this fixed?' That financial worry has now been lifted. She's about to be the first patient at what's believed to be the country's first free dental clinic for otherwise healthy adult patients. Which tooth? It's up the top. Dentist Susan Gorrie and assistant Lisa Kahi are the first volunteers. I think it's really great that they're taking the time to do it. It's really generous. That support from local dentists is key in the development of the new clinic, part of a $2m extension to the Canterbury Charity Hospital. They came forward to us and said, 'Can we offer a service?' And we were very happy to accommodate them. So far 25 Christchurch dentists have offered their time for free. They'll each work on a roster system, taking turns to see patients. They'll work for two sessions a week at first, but that's soon expected to grow. TOOL WHIRRS We're starting off with those patients that are eligible for WINZ support We're starting off with those patients that are eligible for WINZ support but need a lot more dental care than WINZ actually pay for. The Canterbury DHB, like others, offers subsidised dental pain relief, but at $30 to $40 a visit, it's still unaffordable for many. I wish we could build 10 dental units, not one, but I'm just grateful to the people of Canterbury that have supplied the resources that we can do at least what we can do. They're expecting a flood of patients. It's great to be able to give something back to the community. Like Maree, they'll be referred on from their own dentists. Lorelei Mason, ONE News. There's been a wave of coordinated bombings across Iraq, including attacks on at least 10 locations in the capital, Baghdad. 62 people have been killed and dozens wounded. Many of the dead were Shia pilgrims gathering for a religious festival. In Hilla, two car bombs exploded near a restaurant frequented by police, killing at least 19 people. A man accused of shooting three people dead at a party in the US has given himself up after a three-day manhunt. Desmonte Leonard (22) is accused of opening fire at a pool party in Alabama. Mr Leonard was wanted in three states before he turned himself in after being contacted by members of his family. He's been charged with three counts of murder. More than 43,000 acres of land, nearly the same size as Washington DC, have been scorched bare by wild fires in Colorado. 400 fire crews are fighting against the blaze which has claimed at least one life and forced hundreds from their homes. But winds and dry conditions are making it difficult to contain the fires. We all know the risks of sunbathing and tanning beds, and that's led many of us to try chemical spray tans as a safer alternative. But as Channel Nine's Jessica Rich discovered, they may not be as safe as we think. FUNKY MUSIC From our Hollywood celebrities... CAMERA SHUTTERS CLICK ...to everyday Aussie women ` I love spray tans. You feel a lot better about yourself. Spray tans have been seen as a safe way to get that golden glow. Or so we thought. Some scientists in the US are worried a chemical inside the spray may pose a health hazard. Studies were carried out on DHA, the key ingredient that turns your skin the colour brown. The worry is that should you inhale the fumes, the DHA would enter your lungs and absorb into your bloodstream. That could damage DNA and cause tumours. It's winding up in your respiratory system. I'd be very concerned about the potential for lung cancer. Health authorities here and in the US have approved the use DHA on the skin only. But when hidden cameras were sent into American salons,... Do you offer protection? ...few offered protective gear. If you're worried about the effects of inhaling the spray tan fumes, ask for a mask and look for a salon that has some sort of an extraction system. This one here comes equipped with high-powered fans and a secondary filtration system. We also now have them available to other clinics to purchase, to help alleviate this, because there is an element, it's atomised in the air, and you're gonna be breathing it in. If we're going to make any pronouncements as to whether it's safe or dangerous, we need to know more. Just ahead ` a sombre trip for the Irish rugby team to the red zone. The Irish rugby team's on-field woes have been put into perspective. The squad's arrived in Christchurch today ahead of the second Test against the All Blacks. Ireland's first assignment was to visit the central city's red zone. Blair Norton went with them. Touching down at Christchurch Airport, the Irish could be forgiven for wondering what earthquakes? The squad quickly got an up close and personal view of the new Christchurch. You can just feel the emotion, and it's hard to not get wrapped up in it. We were obviously disappointed last Saturday night in a rugby context, but this puts it all into true context ` that was just a game; this is real life. A deathly quiet bus trip though the red zone brought into stark reality what most had only read about or seen on TV. Even just being here is very humbling. And like I said, it's quite emotional, really. Irish scrum coach Greg Feek and his fiancee were affected in a very personal way. What's now a car park used to be his cafe, but Feek's more aware than most that bricks and mortar can be replaced. Lost a close family friend, so that was pretty hard, particularly for Jess. She struggled with that, and we were in Ireland at the time. Christchurch is Feek's second home. The 36-year-old spent most of his career in the city, playing 63 games for the Crusaders. Whenever I brought people to town, I always brought them around this area and did a little bit of a drive around. The Irish were able to share their thoughts with some of their countrymen who've come to help in the demolition of the city. It's hard to believe myself, and I've been here for the last six months nearly, and I still look around at the town. I don't believe it's just going to be flat land this time next year. The spirit of the city, however, will remain. For me, Christchurch is special cos of the people in it, and you always come back for that, so you just hope the city can get going again, you know. Hosting the Irish for a Test match is a sign that despite the devastation, things are on the mend. Blair Norton, ONE News. Now to the weather. A cold front sweeps on to eastern regions tonight, followed by a trough tomorrow night. The high over the lower Tasman Sea is also slow-moving, extending a weakish ridge up on to the North Island.
