Our Changing World: Inside a fire lab
science environment 28 May 2025
New Zealand experiences more than 4,500 wildfires every year – and the risk of big, destructive wildfires is increasing with climate change.
Ellen Rykers visits the fire lab at the University of Canterbury, a purpose-built facility for setting things on fire and studying how they burn.
Researchers can burn couches or create fire tornadoes. But today, Ellen is with PhD researcher and firefighter Kate Melnick, who is researching gorse, a prickly shrub that is both common and flammable.
We join Kate as she sets up a large gorse bush in the lab, ready to burn.

Media in the middle of political skirmishes over sickness and health
Last weekend's Sunday Star Times digs into the political battleground of healthcare. Photo: Sunday Star Times Mediawatch : This week the latest Ipsos Issues Monitor survey showed 'inflation/cost of living' was - again - the top concern of Kiwis. No surprise there - or that 'healthcare/hospitals' was in second place. "It continues on its upward trend, reaching its highest level of concern (43 percent) since tracking began," Ipsos said. That - and the fact that more of those surveyed chose Labour as the party most capable of managing health - would have stood out for the government. The same is true of how the issue plays out in the media. Under the headline The political problem of health Health Minister Simeon Brown told the Sunday Star-Times last weekend the job "matters to every New Zealander from the moment they're born to the moment they die. It's a huge responsibility, but there's also significant opportunity." He'd just announced an opportunity for private hospitals - instructing Health NZ to make long-term deals with them for elective surgeries. "We haven't been ideological about it, we've been focusing on pragmatic solutions to ... maximise what's delivered both in the public and private system," Brown told Newstalk ZB the same day. The next day, New Zealand Herald political editor Thomas Coughlan reported official papers showed Treasury reckoned further cuts to health would be needed to meet the demands of the government's health delivery plan. But that didn't come up when the prime minister appeared that day on Newstalk ZB for his regular Monday morning chat. The host Mike Hosking said he couldn't agree more when the PM said people don't care who's doing their long awaited op when they are staring at the hospital ceiling. But then Hosking told the prime minister about an interview last week with a Christchurch surgeon who works in both the public and the private systems. "We need to be more flexible in public (hospitals). They even come round at one o'clock and say it looks like you'll finish after 4 or 4.30, so we won't let you do your second case," Chris Wakeman told Hosking last week. "You wouldn't close your factory at 4 o'clock if you still had work to do," he added. Later, Mike Hosking read out a text from an unnamed listener who claimed nurses and anaesthetic technicians insist operating stops early if it looks like it's going to go past 4pm. The following day Mike Hosking asked Brown if surgeries that might overrun 4pm were routinely postponed. "Look, there are heavily unionised contractual arrangements in the public system and so you do end up with inefficiencies throughout the system. Those issues need to be dealt with by Health New Zealand to make sure that it is more efficient," Brown replied. "These union agreements ... drive inefficiency and a lack of productivity. These are issues that do need to be resolved as part of (Health New Zealand) negotiations with the unions." Health Minister Simeon Brown Photo: RNZ / REECE BAKER "Absolutely not. The limits are more about management decisions on staffing costs, availability of recovery beds and how to distribute operating theatres between acute and elective work," Sarah Dalton, executive director of the Association of Salaried Medical Specialists told Mediawatch . "The barrier to providing more elective surgeries is a refusal to pay staff required to work longer hours ... and inability to provide sufficient staff to run our operating theatres to their maximum capacity." "We don't have anything in place that would stand in the way of doctors opting to work in a different work pattern or longer hours. And in fact, many of them frequently do. "Typically surgeons and anaesthetists work 10 hour days. A number of hospitals sometimes run what are sometimes called twilight theatres in the early evening or on weekends. "I don't think the way that the discussion has been presented is entirely fair - and it is somewhat misleading. "It is concerning to us that 'private' is seen as the answer when in fact they are already near capacity for what they can do. And we also have significant doctor shortages." Sarah Dalton Photo: LDR / Stuff / Kevin Stent Hosking [ returned to the issue] with Health NZ's Chief Clinical Officer Dr Richard Sullivan on Thursday. He said the proportion of "early finishes" in theatres doing elective surgery is declining - and under the government's 'elective boost' programme they had been doing some surgeries on Saturdays and Sundays too. "It's more than just the unions. You'd need a quite a big workforce to run full Saturday lists all the time. That's not to say we shouldn't look at that, but we need the most efficient way of getting people through our theatres," Dr Sullivan said. Hosking told his listeners the bottom line in public hospitals was: "If it's 4:30, we're going home." There's a bit more to it than that. While there is some extra capacity in theatres, many more people would have to be paid for more hours to do more out-of-business-hours. They don't have all the staff to do a lot more of elective surgeries, in either public or private hospitals And as the Herald' s Thomas Coughlan reported earlier this week, Treasury reckoned the Health Delivery Plan targets could mean increased spending cut targets in the year ahead. Health workforce pay increases would be limited to a degree described as "unprecedented," Treasury documents also stated. In the Herald , Brown rejected Treasury's conclusions. He said government provided Health NZ additional funding in three successive Budgets and Treasury had not consulted the Ministry of Health or Health NZ before reaching its conclusions. "Why do we still have 10 days' sick leave?" Hosking also asked the PM last Monday. He said the question had been put to him by "my tech guy" working at his house. The tech guy got a headline-making response on that from the nation's leader. "So we had five sick days until Jacinda [Ardern] decided we needed ten for Covid. Can we agree that it's gone-ish - and therefore we might need to do something about sick leave?" Hosking asked. "We might need to do things about pro rata and sick leave as well, because you know, people who are on part time contracts are getting full-time 10-day equivalency. Brook Van Velden is working through some of those issues," Luxon replied. The possibility of that went straight into Newstalk ZB's news bulletins. When the prime minister did his turn on RNZ's Morning Report soon after that, he was asked if he would support a cut in sick leave. "Well, I think there's probably a need for us to look at it ... and just make sure that we've got that setting right," he replied. ZB's political editor Jason Walls was puzzled. "Sick leave is an entitlement that everybody has. So it's not just some beltway story. It is an interesting thing for the Prime Minister to bring up. It was just Mike's mate that was talking about it." But Mike's mates behind the mic at Newstalk ZB were teed up to talk about sick leave all day. "A very strong hint that 10 days of sick leave might be going the way of the dodo," was Kerre Woodham's take when she followed the Mike Hosking Breakfast . "I get that it's a godsend if you are prone to infections during winter, but really spare a thought for the employers." Employers such as perhaps Nick Mills, a hospo guy in the capital who's also the host of Wellington Mornings on Newstalk ZB. "I go with the flow. But I'm in an industry where people take the absolute mickey," Mills told his listeners in the capital. "They're just teasing it a bit at the moment on the fact that it's going to be for only part- time employees, but that's going to change," he said. One hour later they were hearing more on this on ZB in Canterbury from the local host, John MacDonald. When Matt Heath and Tyler Adams took the ZB mic for the full national ZB network at noon, they had a similar sense of what was common sense. "10 days a year? Does the average person walking around need 10 sick days a year? I don't think so," Heath said. The questions for the workplace relations minister Brooke van Velden followed. On ThreeNews and Checkpoint she batted back questions about whether it was a gender issue. She was also taken aback that this was a talking point at all. "The only reason we're talking about this is because Mike Hosking was talking about it this morning. There was nothing from the government side to say we had an announcement to make," she told ThreeNews . In the end it will be months before all this is fully aired in Parliament, long after Mike Hosking's tech guy first put it on the agenda.

Youth offending drops with safe, stable housing
Photo: RNZ / Nate McKinnon An Otago University study has found a link between safe, stable housing and a reduction in youth offending rates. The study looked at the relationship between different types of housing assistance, including emergency housing, public housing, and the accommodation supplement. Lead author Chang Yu said researchers found clear links between housing deprivation and alleged youth offending. "We found offending decreased significantly among young people living in public housing or receiving the accommodation supplement, compared with the general population. "The research underscores the importance of stability in housing assistance - more stable forms of assistance are associated with better outcomes beyond shelter, particularly in reducing youth justice involvement. "Emergency housing - which provides accommodation for seven nights - remains a highly debated model, attracting both support and criticism. This study adds to the debate by showing that emergency housing does not appear to reduce youth offending." The study found that 3 years after moving into public housing, alleged offences and court charges among young people reduced by 11.7 percent and 10.9 percent more than the general population. Rates of alleged offending and court charges also decreased by 13 percent among those receiving an accommodation supplement. Yu said stable and longer-term housing can positively impact whānau and provide social cohesion. "If you have stable housing, then the kids can consistently attend school and develop community bonds. The parents will have more time to spend with their children." he said. It found Māori and Pacific youth face systemic disadvantages in both the housing and justice systems. "Housing deprivation is closely linked to justice sector involvement. This suggests that youth offending cannot be addressed in isolation from housing conditions - addressing structural inequities in housing is essential for meaningful justice reform." Yu called for the government to move beyond short-term solutions for housing that provided more security for people to survive.

Approaching life-changing diagnosis for "missing millions" with ME/CFS
Photo: Professor Warren Tate Photo: Supplied Anyone who has or knows someone with ME, chronic syndrome fatigue or long covid knows that being believed is one of the toughest parts of having the condition. University of Otago Emeritus Professor Warren Tate has dedicated his life to researching ME/CFS and is considered a leading authority on long covid. Along with his team, he has been developing a diagnostic test, that so far has shown promising results. If implemented, it would be life-changing. Warren and his co-researcher Dr Katie Peppercorn have also released a one-of-a-kind book to help clinicians and researchers find ways of better understanding post-viral conditions and improve the lives of those 'missing millions' affected with ME/CFS and most recently long covid.
