Beetle mania
A nondescript field in Cromwell is the world’s first—and only—nature reserve dedicated to the protection of an invertebrate.
Birds of play
Packs of kea are reliable entertainers in places such as Arthur’s Pass or Glacier Country, and new research is showing that kea are smarter and have more complex communication than previously thought. But large flocks in tourism hotspots conceal the fact that kea numbers are dramatically falling across the Southern Alps. Why is this? How can we reverse it? And what do we still have to learn about them?
State of mind
The number of New Zealanders seeking help for mental illness is rising: it’s now the third-highest cause of ill health in the country, and doctors, specialists and community organisations are struggling to meet the need for treatment and intensive care. Meanwhile, researchers are attempting to identify what takes place in the brain before and during a mental illness. It’s a young and inexact science—and at the moment, it’s all we’ve got.

Most of the stellar yachting careers of New Zealand’s America’s Cup sailors began in humble seven-foot boats—a class now a century old—designed by a Public Works employee who couldn’t swim, and who was too hard up to build anything larger.
The long haul
Antarctica is a puzzle that science is racing to solve. The continent shifts from stable to unstable, frozen to melting, without much warning—and we don’t know why, or how. This switch hasn’t taken place in the century we’ve been observing it. But Antarctica has its own records that go back millennia, buried in the sea floor beneath hundreds of metres of ice. To retrieve them, a New Zealand-led expedition journeyed to the heart of the Ross Ice Shelf—a featureless, inhospitable expanse the size of France.
The legend of the argonaut
A rare and misunderstood octopus, the argonaut lives far out to sea, where females construct fragile shells to live in, marble-sized males woo them with severed arms, and much of their lifecycle has never been observed.
Farming for our future
As things stand, the land can’t endure our enterprise much longer. If it’s to sustain our grandchildren, we have to change the way we think and cultivate. The Our Land and Water National Science Challenge is helping us forge a new accord with the soil beneath our feet.
Gold rush
Mānuka honey has exploded in value in recent years, and now it’s a high-stakes business, attracting hive thieves, counterfeit products, unscrupulous players—and triggering a race for the blossom every spring, wherever the trees are in flower.
3d test
"By it and with it and on it and in it," said the Rat. "It's brother and sister to me, and aunts, and company, and food and drink, and (naturally) washing. It's my world, and I don't want any other.
Track and trace
Most introduced mammals have had a devastating effect on native wildlife, but one species is bucking the trend. About 80 conservation dogs are deployed around the country, helping to protect vulnerable native species by leaping into action at a single command: Seek!
The last of the giants
Kauri create shelter and nourishment for other species to grow, but now, a disease without a cure is killing these forest giants one by one. In the past five years, the infection rate of kauri has more than doubled in the only forest where it's monitored—the Waitakere Ranges. At least one in five trees there are doomed. Can we save the species?
Robots are here to care for us
A surge in New Zealand’s elderly population is on the way, yet health and home-care services are already stretched. A joint research project between New Zealand and South Korea—which is already experiencing the demographic swing that awaits us—is investigating one solution: robots.
Ready or not
Preparing for a natural disaster has long been considered a matter of personal responsibility—but what happens to those without the finances to stockpile supplies or the physical ability to run up the nearest hill? Lessons learned during New Zealand’s most recent crises have shifted how towns and cities are building resilience. Researchers with the Resilience National Science Challenge and other agencies now believe that strong community connections will best help everyone ride out a worst-case scenario—but can we form those bonds in time for the next big one?
Why are whitebait on the brink of extinction?
There isn’t a catch limit on the lucrative whitebait fishery, which threatens to extinguish a cherished tradition and a small family of fish in one sweep of the net. If nothing changes, two whitebait species will be gone within five years, and the rest by 2034.
The lava caves hidden beneath suburban Auckland
Hidden beneath quiet suburban streets are clues to Auckland’s tumultuous geological past: lava caves.
Exploring the underwater realm far from our shores
Barely seven per cent of New Zealand is land. The rest of it, the wet bit, covers four million square kilometres. In 2016, photographer Richard Robinson won a Canon Personal Project Grant that enabled a dozen expeditions into this vast marine prairie, arguably the country’s last great tract of undisturbed wilderness.
We can edit genes better than before. Should we?
Gene editing is now being used in research around New Zealand, usually to ‘switch off’ genes one by one in order to figure out what they do. Overseas, this technology has started to emerge from the lab—it has the potential to help eradicate pests, save threatened species, even cure diseases—and soon, we’ll have to decide whether gene editing should be permitted more widely in New Zealand. What are the risks? What could we use it for? And how should we decide?
The fate of the Nino Bixio
On August 17, 1942, an Italian prisoner-of-war ship carrying Allied soldiers was torpedoed off the coast of Greece. Crammed into the forward hold were 174 New Zealand servicemen. One of them was Ben Stanley’s great-uncle.
The coming swarm
Every summer, a plague of wasps gathers, ruining picnics, harassing trampers and disrupting ecosystems. Wasps outcompete bees for food, costing New Zealand about $130 million each year in loss of honey and pasture crops. Where wasps abound, biodiversity suffers: butterflies disappear, songbirds stop breeding and invertebrate communities are looted. But there’s hope on the horizon. Scientists are developing weapons, both biological and genetic, in a bid to cure the pestilence, once and for all.
Last chance to see
Twice the kākāriki karaka has returned from the dead. Orange-fronted parakeets were declared extinct in 1919 and again in 1965, but each time, the birds were concealed deep in the beech-forested valleys of Nelson and Canterbury. Now, the bird is approaching its third extinction, and this time, rangers have already scoured the valleys for hidden strongholds. This time, there isn’t a secret population waiting in the wings.
