Due to the live nature of Tonight, we apologise for the lack of captions for some items. Tracking down more than 200 Chinese students ` immigration targets a visa scam. We find a potentially deadly chemical cocktail available for sale over the counter ` a warning about a drug known as 'bath salts'. And they put the squeeze on boyracers, now they're putting the results on show ` the first crushed car is to be a museum piece. A large dark wall is lining up the rain clouds over the western ocean, so we have an alert for you. That's just ahead. Kia ora, good evening. More than 200 Chinese students using fraudulent visas are the target of immigration officials tonight. Authorities are asking the students to step forward or risk being deported. The immigration scam, run out of China, involves the use of fake qualifications and other false information. Joanna Hunkin has the details. More than 20,000 Chinese students come here each year for our education, but some will soon learn a hard lesson ` that Immigration NZ doesn't take kindly to fraud. There's zero tolerance for persons that are involved in fraudulent activity. But the reality is if they are here unlawfully or they don't have a current valid visa, then they could potentially be deported. 279 fraudulent visas were obtained in Beijing and uncovered four weeks ago during a routine audit. Of that total, 231 students are in the country with the visas. Now they're being tracked down. So we have two teams operating in the Auckland area, um, locating students as we speak, and today we've located 10 students who we're currently interviewing. The immigration minister is downplaying the fraud. We have about 25,000 applications a year from China, so in the scheme of things, it's pretty small. She says the investigation shows the system is working. The system is showing that it actually is robust and that these occurrences are rare, thankfully. But having said that, um, we have to investigate it. We're investigating it and want to make sure that we can do whatever we can to make sure it doesn't happen again. The fraud's been traced back to two agents in Beijing, and students may not know they've been a party to fraud. That's why we'd like people to come forward to, um, tell us their story, their version of events. Uh, we'll listen to that. Those who don't cooperate could find themselves deported from NZ and subject to a five-year ban. Anyone concerned they may be involved should approach Immigration NZ immediately. The agency says the sooner people come forward, the easier the whole process will be. Joanna Hunkin, ONE News. Meanwhile police in Wellington have named the dead woman found just off a track in Mt Victoria. Sofia Athanassiou's body was found by joggers on Monday morning. Police have arrested and charged a man with the murder of a woman in Christchurch. The arrest comes after forensic teams scoured this unit in the suburb of Burwood after a woman's body was found inside. While police won't comment on the nature of the investigation, the news has shocked neighbours. I just feel sick in the stomach, yeah. I just want to move on. Move out. The identity of the victim has not yet been released as next of kin are still being notified. A post-mortem will be conducted tomorrow. Meanwhile police in Wellington have named the dead woman found just off a track in Mt Victoria. Sofia Athanassiou's body was found by joggers on Monday morning. Post-mortem results on the 39-year-old were inconclusive and further tests are underway. Police say they have not ruled out drugs as a factor in her death. That's one of the reasons that the tests are undertaken, and as I say, we have to wait for possibly four to six weeks to get some answers there. Police want members of the public who may've seen Ms Athanassiou that morning to come forward. Authorities here are now facing a dangerous new drug type that's been linked to a series of attacks involving extreme violence overseas. The drug, known as 'bath salt', is described a being more menacing than methamphetamine. Customs here say they are intercepting the drug every day. Helen Castles has more. (GIGGLES) High on an dangerous and potentially deadly synthetic drug. A drug known as mephedrone ` with a street name of bath salts. A substance that's the ringing alarm bells around the world, and now it's here. I suspect that this might be a wee bit more dangerous than P, and we wouldn't want to see any more harm come to people in the community. SIREN WAILS At the weekend police confronted a 19-year-old Greenhithe man who was thought to have taken the drug. The teenager had to be tasered twice, pepper-sprayed and physically restrained. Before the car had even stopped, he charged at the vehicle and leapt on to the bonnet and into the front windscreen. Um, he came off the car. I believe he took a windscreen wiper with him as he went. Police are awaiting test results to confirm exactly what he'd taken. Experts say taking bath salts is like taking methamphetamine and cocaine at the same time. They're class A drugs. But bath salts or mephedrone is categorised as an illegal class C drug. I'm sure that the lawmakers and us government officials need to escalate that very very quickly. ONE News found this locally distributed bath salt available to purchase over the counter. It claims to be legal and natural, but the full ingredients aren't listed. And on its website under 'disclaimer', it states the product isn't for human consumption. Helen Castles, ONE News. The coalition relationship between National and the Maori Party is showing signs of strain tonight. The Maori Party's upset after John Key said he may ignore recommendations from the Waitangi Tribunal about water ownership. Political reporter Jessica Mutch is following the story. Maori Party co-leader Tariana Turia trying to evade media outside the tribunal hearing in Lower Hutt. First reversing, then trying a side road, before being ushered in the back door. Eventually, though, she fronted up. I do think, uh, that it was remiss of him to make those comments right at the beginning of the process. She's talking about comments made by the Prime Minister about this urgent hearing. It's looking at whether the asset-sales process should be delayed while there are still questions over Maori water rights. John Key says he may ignore the findings, and that's what's upset his coalition partner. < Does this impact on your partnership arrangement with National? Well, that remains to be seen. < What do you mean by that? Well, exactly what I'm saying. It remains to be seen. Well, look, it's an ongoing and healthy relationship. We have good debates. There are many areas where we don't agree. He's making no apologies for his comments. My position's rock solid, and it's not about to change. In my view, no one owns water. The Mana Party leader says the Maori Party is too weak to walk. Oh. That's just bark, bark. But, um, they're not serious. They just` They just want to be seen to be saying something so that people don't walk away from them. But, um, they're going to stay in. Labour says this is another crack in their relationship. I don't think it's done them any good, but the Maori Party is desperately holding on to the National Party, and it doesn't look like they're going to be walking away. Who cares what they say and what they think, actually. The Waitangi Tribunal is due to hear submissions until at least next week before they make recommendations. And if it's ignored, some are threatening to take the issue to court. Jessica Mutch, ONE News. The Prime Minister's also waded into the controversy about the future of Christchurch Cathedral. John Key said he thought some of the existing structure could be salvaged and re-used when a rebuild eventually goes ahead. His comments follow the release of a detailed engineering report which claims the quake-damaged cathedral can be saved. It's my view that it would be nice in terms of rebuilding the cathedral, whether it's on the, you know, part of the existing facilities or a new building that incorporates much of the, you know, the old cathedral. I think that was a much-loved building. The report is being considered by the government and the Anglican Church, which believes it needs to be pulled down entirely because it's not safe. Now the most famous crushed car in the country is set to keep its high profile. The vehicle was the first to be flattened under tougher laws aimed at putting the squeeze on boyracers, and now it's to become a museum piece. Arrun Soma explains. Gone in less than 60 seconds. From prized trophy car to scrap metal, now soon to be a museum exhibit. It's much bigger and flatter than I thought it was going to be, and the wow factor for our visitors is going to be excellent. The car was crushed by Police Minister Anne Tolley under the three-strikes law, which aims to put the brakes on illegal street racing. But now this wrecked heap will sit alongside famous warplanes, classic train carriages and the like at the transport museum MOTAT. After this car was crushed last month, it was put up for auction online. MOTAT won it, paying just over $800 ` the money going to charity. The carcass will go on display to educate about how crushing machines work as well as road safety. This is the result of not being safe on the road, and it's something that we take very seriously for our communities to make sure that we can get that message out to them. But it's also been bought to pull in a crowd. Acquiring new items like this mean that we can remain relevant in the community today, and we know that people are really interested to come along and see it. The crushed car will be displayed in August. Arrun Soma, ONE News. Just ahead ` are the poor and the desperate being targeted when pokie machines are placed in less affluent suburbs? And extreme road rage ` incredible video of an angry motorist clinging to the bonnet of a car. ENGINE RATTLES SONIC CRACKLING, ZAPPING Debt comes in all shapes and sizes. SONIC CRACKLING, ZAPPING Sometimes borrowing is a smart thing to do,... SONIC ZAPPING INTENSIFIES ...and sometimes it isn't. SONIC ZAPPING SOARS Shrink your dumb debt. It's all part of being sorted. 1 As ONE News continues our investigative series on gambling and pokie machines, Around 50 jobs are expected to be axed after a decision that means Timaru's prime port will lose its status as a container port. The global container lines Maersk and Hamburg Sud are withdrawing from the city's port in favour of the Port of Otago. It's going to be very difficult to maintain a container service without ships calling, and, uh, that, you know, will lead to closure effectively. The workers' union says it's the direct result of international shipping lines forcing ports within NZ to compete against one another. As ONE News continues our investigative series on gambling and pokie machines, we've learnt SkyCity Casino's host responsibility programme is to come under official scrutiny. The Gambling Commission's given the casino notice of the review, which is three years overdue. The last one was in 2007, but it's meant to take place every two years. Now to our series on gambling and just where pokies are found away from the casino. As Lisa Owen discovered, many are located in those communities which can least afford to feed out-of-control gambling habits. Tau's family is everything to him now,... READS: ...mark it on the map. ...but for a decade his story was very different. Tau was utterly consumed with playing the pokies. It almost killed him. Basically, I just wanted to end it all ` pretty much just drive the ute off the cliff. Living in South Auckland, he didn't have to go far to feed his addiction with plenty of gaming machines. I think they are being preyed on. So let's look at who the winners and losers are when it comes to pub pokie numbers in our biggest city. Auckland Central has the most ` 192 ` but it also has the worst score on the deprivation index ` a less-than-perfect 10. Now, that measures things like income, education and health. Papakura and Otahuhu are also high-rollers in both the pokies and deprivation scores, with Manurewa and Henderson rounding out the top five areas with the highest concentration of pokies. So, is the location of these machines just the luck of the draw? They are to going to areas where there are people that are that desperate that they want to try and get that quick money. Councils set the rules when it comes to pokie numbers and placement. Under the old Auckland City Council, for example, venues had to be 100m apart. Figures show that overall gaming machine numbers are decreasing, but they're generally disappearing from wealthier areas at a faster rate. Manukau is still in the top 10 for pokie density in Auckland. We've got some over here at the centre, then we've got one just around the corner and also one just behind us, and that's just within a K. But in some spots, demand is apparently still outstripping supply. I have been to a couple of places where they have pokie machines and you are actually queuing up to play a machine, and you can be queuing up for 20 minutes, an hour. The Auckland supercity will thrash out its pokie policy at the end of this year. Lisa Owen, ONE News. Accused internet pirate Kim Dotcom has tweeted an offer to the FBI, promising to go to America on his own accord, but with conditions. The internet millionaire first wants the US government to grant him bail there and unfreeze funds so he can pay lawyers and living expenses. This comes after Dotcom's extradition hearing ` originally due to take place next month ` was put off until March next year. He's wanted by the US to face allegations of money laundering and copyright infringement. From the US, a new report and a major alert about the speed of climate change on our planet. Hundreds of scientists from around the world say there is evidence that global warming is accelerating and it's linked to extreme weather. So is it too late to reverse this worrying trend? The ABC's Sam Champion with this report. WIND ROARS The extreme weather of 2011,... Oh, gosh. That is a monster tornado. ...the worst drought in a decade, even the recent headline of the hottest 12 months we've ever lived through ` all a global concern. Areas of the world are getting hotter and drier,... LIGHTNING CRASHES ...flood zones getting pummelled. Extreme weather becoming the rule not the exception. And according to many scientists, global warming is a cause. What we know really well about global warming is that it increases the likelihood of more extreme events. LIGHTNING CRASHES Today, hundreds of scientists from 48 countries released their annual 'state of the climate' report, which shows the trend towards a rapidly warming planet has been accelerating. The study examined headlines like Rising Temperatures Both on Land and in Our Oceans and examined disappearing sea ice. 2011 showed the second-smallest area of ice on record. Also noting glaciers around the world continued to shrink. Greenland has one of the largest ice bodies in the world, and pictures now show Greenland's glaciers are melting 30 times faster than they were a decade ago. Over the last century, sea levels have risen about 10 inches, but by 2050, scientists predict the levels will increase another foot. For the first time in its history, this study says 2011 weather extremes are connected to man-made global warming. This study does not make predictions for the future, but it begs the question have we reached the tipping point? Scientists tell us not yet. The report also notes that man-made greenhouse gases are on the rise, and they're at the highest levels since scientists began keeping records. Now to a glimpse of the future of life in the big city. New York's mayor wants to build teeny apartments the size of two parking spaces, saying they could solve a lot of housing problems. The ABC's Amy Robach tests out the concept. Hi. Hi. Hi, Graham. I'm Amy. Nice to see you. Lesson in small space. We went to Graham Hill's high-end convertible apartment ` just 420ft2. It can go from a living room to two bedrooms to a dining room for 10. How many chairs did you fit in that one closet? Uh, so there are 10. There's more to it than meets the eye. This microwave is also a convection oven. Need some burners for your pots? Well, take a look. Pull them out of here and just plug them in. Then we've got our refrigerator in this drawer, a freezer down below it, and then up here, everything has multifunctions and is stackable. Even this wall is magnetised for spices. And instead of a trash can, there is an electronic composter right here. DING! Next we headed to ABC producer Lauren Effron's apartment, just 300ft2 ` the size of two parking spaces. 300 even. Yes. Exactly. 300 even and I share it with my boyfriend, so there's two of us in here. 150ft2 for each of you. Yes. This is how I get into bed every night. You climb the stairs. And you'll see that this is 3ft of space. And everything serves a dual purpose. So this table is multifunctional? Yes. So this serves as a desk, this serves as an ironing board, this serves as an office. Do you think that anybody could live like this? Yes, absolutely. Yes. I mean, if you just learned to pare down your stuff and just say, like, 'Look, this is what I absolutely need to survive.' And it's not like I'm living in the wilderness or something like that. I have a blender. I have a coffee pot. All you need to live in this concrete jungle. And finally, what would you do? This was the scene in New Jersey. In Australia, a stoush at traffic lights has led to some extreme behaviour from this driver, just outside Melbourne. Believing he'd been cut off, he leapt on the bonnet of another man's car. But when the car started moving, he refused to jump off, at one point even making a call on his cellphone. Both men are facing charges over the incident. Just ahead, from The Tron to the City of Angels, the Waikato's winning voice sings for Jay Leno. # Won't you settle down with me? # Settle down. # And I have a mainly fine forecast for you, but there's rain on the horizon. Nah, I'm good, mate. I'm good. Ohhh. Ohhh. May I help you, sir? Ohhh. May I help you, sir? Hey, bro. I'm Tim. From NZ. I won the, uh... the MasterCard prize, where you get to tour with the All Blacks. Fellas! Oh! Danny C! Oh yeah! Nonu, Nonu, Nonu! Boom! Richie. Bring it in, mate. Register and use your MasterCard before September 15 and you could go on tour with the All Blacks. Good to see ya. Good to see ya. Yeah, you too. So, who am I rooming with? Kiwi-born pop star Kimbra is receiving rave reviews, after performing on one of America's top late-night talk shows. The 22-year-old took her unique sound to the Tonight Show with Jay Leno and his audience of four million. Here to perform Settle Down from her new CD Vows, please welcome Kimbra. AUDIENCE CHEERS She must've been nervous... (SCATS) ...performing for a TV audience almost the size of NZ's entire population on the Tonight Show with Jay Leno. # I wanna settle down. # I wanna settle down. # It's a really big deal, and she looked great, and she nailed it. And I think she was also probably a lot more experimental than a lot of the musicians that go on Leno are. From run-of-the-mill singer-songwriter, Kimbra emerged a pop star in the making. Her debut album went platinum both here and across the Ditch. And the Best Female Artist goes to... Kimbra. AUDIENCE CHEERS Oh, thank you so much to Aria for presenting me with this award. I really did not expect this. Then came this game-changer. # ...and I wouldn't catch you hung up on somebody that you used to know. # A catchy single that spent 22 weeks at number one on the US charts and scored her the spot with Jay Leno. Tweeting from behind the scenes, Kimbra took a few snaps for her own Leno memories. That was great. Thanks so much. But there will be plenty more to see from this songstress yet. She'll have a really strong career, a really long career, rather than a fly-by-night hit the charts, then disappear. A prediction Kiwis are hoping she fulfils. Kim Vinnell, ONE News. Weather time now with Renee. Hi, everyone. High pressure reigns supreme over the country for another day or two. However kinks appear in its armour tomorrow as it battles with a complex trough approaching from the Tasman Sea. Tonight, as the high moves further east, the ridge retreats back over the North Island, allowing that complex trough to approach the South Island tomorrow. The trough is preceded by a strengthening northwest flow that builds across the South Island later tomorrow. Although rain develops in Fiordland tomorrow morning, the rain-bearing front isn't expected to move onto Fiordland until evening. High cloud thickening over the lower South Island. Nor-westerlies becoming gusty from Invercargill to Queenstown. Rain with heavy falls from afternoon for Milford Sound. Drizzle turning to rain for Hokitika and Greymouth. Increasing high cloud with nor-westerlies developing for Timaru, Ashburton and Christchurch. Kaikoura and Blenheim are fine. Cloudy periods with freshening northerlies about the capital. New Plymouth gets a grey Thursday with the odd shower and a high of 13. Frosty first thing about Masterton, with nor-westers developing. Hawke's Bay gets sunshine and light winds. Mainly fine after a frosty start for Taupo and Rotorua. Cloudy periods developing with the chance of a shower for Whakatane and Tauranga. Long fine spells, light winds and a high of 15 from Whangarei to Kaitaia. Cloudy periods for the rest with the chance of a shower. Drizzly conditions Friday, Saturday and Tuesday for Dunedin. Light showers Sunday and Monday. Overcast Friday through Saturday. Drizzle turning to rain on Monday, with a high of 15. A glum line-up for you, Wellington, but it all comes right on Tuesday, with clear skies and a top of 12. Looking good Friday and Saturday, Hawke's Bay. Sunday's not too shabby either, with just a bit of cloud at times. You'll need the raincoat come Monday. A showery line-up for you, Tauranga with drizzle turning to rain on Monday. Light falls on Tuesday, with a high of 16. A fine but partly cloudy start to the weekend, Hamilton. Expect the odd shower here and there on Sunday and Tuesday. And Auckland can expect a rainy start to the new working week, with a high of 16. Light falls Sunday and Tuesday. That's your weather. See you tomorrow. That's it from us here on Tonight. Breakfast is back with updates from 6 tomorrow morning. Thanks for watching. Pomarie. Goodnight. Captions by Hannah Reynolds and Diana Beeby. Captions were made possible with funding from NZ On Air.
