Rare bird in the spotlight
A secretive, critically endangered wetland bird is the subject of the Whakatipu Wildlife Trust's latest 'Talk on the Wild Side'.
Christchurch-based conservationist, researcher and author Peter Langlands will talk about the Australasian bittern (Matuku-hūrepo) and other wetland birds at Skyline Queenstown on Tuesday.
Langlands has received funding from Environment Canterbury for the past two years to carry out research on the bittern, which he calls the "kakāpō of wetlands".
"They've got a really complex behavioural repertoire.
"The male birds make a loud, resonating, booming call that can travel several kilometres."
Langlands, whose book Foraging New Zealand came out last year, lived in Queenstown in 2017 while working for Amisfield restaurant as a forager.
His bulging CV includes collecting data on braided river birds for the Department of Conservation (DoC), and setting up a national database on the bittern.
The "charismatic" bird, of which only an estimated 250 to 750 remain, symbolises the importance of conserving large wetland areas, of which 90% have been destroyed, he says.
"It's a real indictment on how we've treated our lowland wetland environments.
"The paradox is, unlike most critically endangered birds, which are usually confined to sanctuaries or remote areas, the bittern is extremely widespread, but in very small numbers."
He believes there's hope for its future — there's even been a few sightings in the Whakatipu in recent years.
Cash-strapped DoC somehow needs to give the protection and restoration of the country's wetland ecosystems more attention, he says.
"The amazing thing about this bird is if we get the habitat right for them, if we conserve the areas that are left and work to create the right habitats, they can actually thrive.
"They're highly mobile ... and they can breed reasonably fast."

Dogs allowed on Canterbury buses – but is it workable?
Environment Canterbury councillor Joe Davies is advocating for dogs to be allowed to ride on buses. Photo: Supplied/Environment Canterbury A last minute rule change to allow small dogs on buses has left Environment Canterbury (ECan) staff scrambling to make workable. Councillors adopted the Canterbury Regional Transport Plan 2025/35 at a council meeting on Wednesday [July 30] after a late amendment from councillor David East to allow passengers to take a small dog on the bus with a lead and a muzzle. Cr East's motion passed by 8-7, and followed an earlier amendment proposed by Cr Joe Davies, which would have allowed small dogs to travel in their owner's lap, which lost 9-6. This was despite staff advice that dogs are not permitted in the Christchurch bus interchange, administered by the Christchurch City Council, unless they are in a secure carrier. It could mean passengers are able to board a bus with their dog but are unable to get off with their dog at the interchange. Cr Davies has been lobbying for pets on buses for the last two years, following lobbying by resident JJ Smith. He said the plan is a good example of how policy takes time. ''This is about dogs on buses. When people think about taking a pet on the bus, a dog is different because people take them to the park or to visit people. ''Dogs are companions in ways that cats and guinea pigs aren't.'' Environment Canterbury councillor Joe Davies is advocating for dogs to be allowed to ride on buses. Photo: Supplied/Environment Canterbury But Cr Claire McKay said she felt allowing dogs was a risk to public safety, as ''we can never be certain what a dog is going to do''. ECan staff have been working on the regional transport plan since 2021 with the Canterbury Regional Transport Committee, which comprises the region's mayors and Waka Kotahi NZ Transport Agency, and the Greater Christchurch Partnership Committee. The proposed plan had a clause allowing pets to travel on buses, as long as they were in a secure carrier. Cr Grant Edge, who chaired the Greater Christchurch Partnership Committee's hearing panel, said he was disappointed to see the amendment pass. ''It is incredibly naive for us not to have simply adopted the plan. ''As staff have told us, leashing and muzzling has issues with the Christchurch City Council's rules and we have no definition of a small dog.'' Chairperson Craig Pauling questioned how bus drivers will ''determine what is a small dog?'' Dogs may soon be riding on Canterbury buses. Photo: RNZ/Dom Thomas There is still work to do before dogs can ride on buses. ECan staff will now engage with the Christchurch City Council, bus drivers and other stakeholders to come up with a revised code of conduct for pets on buses to present to a future council meeting. The Greater Christchurch Partnership Committee comprises the Christchurch, Selwyn and Waimakariri councils, ECan, Te Rūnanga o Ngāi Tahu and government agencies.

Saving NZ's rarest species
Alborn Skink photo copyright James T. Reardon The tara iti, Alborn skink and rare habitats need urgent help. The first thing people usually say when you tell them where you're from? 'Oh wow, New Zealand's such a beautiful country.' That's true, but the very quality that makes our country so unique and globally recognised is not to be taken for granted. With more than 4000 species threatened or at risk of extinction, the country's natural heritage faces significant challenges from habitat loss, invasive species, and climate change. 'Our natural environment is fundamental to our wellbeing, to our health, and to our economy,' says Sia Aston, Public Affairs Deputy Director General at the Department of Conservation. 'Just in economic terms, 70% of our exports rely on nature, so in a very real sense this country is built on it.' However, she says many remain unaware of the crisis unfolding in our own backyard. While DOC enjoys an earned reputation for its tireless work protecting threatened species and ecosystems, Aston says the organisation is constantly stalked by limited resources and seemingly unlimited issues demanding attention. Just like in an emergency room, triage and focusing efforts where they're most needed is essential, Aston explains. 'Those efforts depend on our work as much as they depend on help and support from every Kiwi. While we do have specific programmes where we're asking for donations, there are multiple ways you can get involved, including volunteering for organised conservation groups.' Among the most urgent priorities currently being targeted are three projects. The tara iti (New Zealand fairy tern), Alborn skink, and limestone ecosystems of the Waitaki Valley. The tara iti is the country's rarest endemic breeding bird and teeters on the brink with fewer than 40 adult tara iti left and of them, only 10 are known breeding females. Found in Auckland and Northland, these tiny coastal birds are ground-nesters vulnerable to predators and storms. Despite their precarious status, there's hope. A recent breeding season produced 17 fledglings, up from nine the previous year and just three the year before, bringing the total population to 50. DOC techniques protecting them include satellite tracking to monitor movements, newly developed zoo based rearing techniques in partnership with Auckland Zoo and intensive nest management techniques that use 3D printed eggs. 'Tracking shows how far individual birds go around the country,' Aston explains. 'Some have even gone as far as New Plymouth from Northland, and they're tiny little things.' The 3D printed replicas are cleverly swapped in during storms to protect viable eggs from damage. 'We go to great lengths to look after these birds with strategic partners like Auckland Zoo,' says Aston. DOC is seeking $1.5 million towards work to secure the tara iti future. Found in a Pakihi clearing surrounded by beech forest, near Reefton, the Alborn skink has an estimated total population of just 30 individuals. Predators like mice threaten their survival, and DOC is taking action. 'With so few of them, they are at extremely high risk of extinction,' Aston says. 'We're looking to build a five-hectare fenced-enclosure to ensure the species' survival.' Currently under construction, this predator-proof fence will provide a safe haven for breeding and recovery. 'Keeping predators out gives Alborn skinks a chance to survive and breed and breathe.' she adds. DOC aims to raise $466,000 for additional work to help the species survive and thrive. New Zealand's limestone ecosystems comprise unique habitats supporting over 150 species of endemic plants. 'Limestone ecosystems are rare and unusual. They are life-sustaining for so many other species, many of which are as yet unnamed.' With 73% of these species confined to areas smaller than 10ha, they're highly vulnerable to habitat loss, invasive weeds and extreme weather. DOC's plan involves removing exotic plants, propagating threatened species, and creating forest buffers for protection. The cost of effective protection securing the future of these ecosystems is $1.4 million for a project Aston says could set a global blueprint for ecosystem restoration across Aotearoa. You can donate directly to these priority projects through the New Zealand Nature Fund (NZNF) – the charitable trust responsible for funds donated to these projects. These projects are already planned; with your support, they can go further, faster. But it isn't just about money. 'We want New Zealanders to fall back in love with their natural environment and be a part of it,' says Aston. 'This is your heritage, and we can be proud of its international recognition. Our environment is very much part of our identity, so I encourage everyone to get involved, volunteer with local conservation groups, or simply go for a walk because as much of a taonga as it is, our nature is free to enjoy.'

What three Rotorua principals think about open-plan classrooms
'When one teacher is leading the whole class, another can provide targeted support to students who need it the most.' She said the school's 130 Year 5 and Year 6 students consistently expressed a 'strong preference' for collaborative learning spaces. Lynmore Primary School principal Hinei Taute. Photo / Supplied Taute said 100% of students surveyed stated it benefitted their learning, and feelings of safety and belonging. 'Our teachers echo those sentiments, emphasising that when 'teacher relationships are right and students and teachers are invested in working together, the magic happens'.' She said students thrived with 'greater agency', such as choosing where they wanted to work, and benefited from diverse learning spaces. 'We've seen first-hand the rapid academic, social and emotional growth of our students when routines are set and teachers collaborate effectively.' Rotorua-based Lynmore School students working in open-plan classrooms. Photo / Supplied She said this was a testament to the school's commitment to teaching excellence and 'a deep understanding of how students learn best'. Kawaha Point principal Maria Gillard said scrapping open-plan classrooms was the right move. She said when she took over as principal in May 2022, student achievement rates were 'very low' - 30-40%. 'I was shocked by how chaotic and disruptive it was for students and teachers working in four large open-plan learning spaces, including two hubs that housed up to 90 children in each. Kawaha Point School principal Maria Gillard. Photo/ Supplied 'It was loud, it was noisy, like having to teach in a barn, and students were able to run from one side to the other.' She and the board immediately decided to transform the two largest teaching hubs. 'We installed permanent glass sliding doors and created three classrooms in each, and reinstated folding doors in some original classroom blocks to redefine them as quieter, purposeful learning spaces.' Two distinct classrooms were also created for younger learners, Gillard said. 'We've worked hard to reshape our learning environment to meet the needs of our tamariki, and now have 12 individual classrooms.' Kawaha Point students studying in one of the school's reinstated smaller quieter learning spaces. Photo / Kawaha School She said some of the school's capital property funding, along with other school funds, had made these changes possible. 'The results speak for themselves - calmer classrooms, improved behaviour, and children who see themselves as confident learners.' Gillard said achievement rates were now in the 60-65% range and trendng upwards. Ngongotahā Primary School principal Eden Chapman said before taking up his role on July 14, he spent 15 years as a principal in 'high-equity, low-decile' primary schools. 'In those environments, open-plan classrooms would have presented far more challenges than benefits — particularly around self-regulation, behaviour, and teacher workloads." Ngongotahā Primary School principal Eden Chapman. Photo / Supplied Chapman, who is also president of the Rotorua Principals' Association, said local principals' feedback was 'varied'. 'Some schools have embraced open-plan and collaborative learning spaces with great success. 'Others found them challenging, particularly for students who need more structured, less stimulating settings to stay engaged.' He said many local principals supported the move back to single-cell classrooms as it aligned better with learners' needs. Chapman said major issues faced by schools were the 'inflated cost of building projects' and overcrowded classrooms. He said the new NZ School Property Authority (NZSPA) had the potential to streamline the 'complex and often time-consuming' process of school property development. 'In areas like Rotorua where new subdivisions are being developed, we believe the Ministry (and NZSPA) need to get ahead of the curve, not play catch-up.' Education Minister Erica Stanford. Photo / Alyse Wright Stanford said the new agency would give schools 'improved project delivery and communication, better value for money, and increased transparency around decision-making'. She said the ministry was developing standard building layouts after considering New Zealand and overseas research on how different learning environments impacted student engagement, well-being and achievement. This would support 'a shift towards adaptable classroom designs that prioritise student needs and local context, over a one-size-fits-all, open-plan approach'. 'While some schools used their open plan classrooms well, classrooms are intergenerational assets, so building them to be flexible and adaptable will ensure they will endure beyond the tenure of individual teachers and principals.'
