In Love With the Weeds
Taxonomist Roberta D’Archino is finding and cataloguing our marine flora, one dive at a time.

We cull hybrids. We steal their eggs, and break up inter-species breeding pairs, all in the name of genetic integrity. Protecting the mauri. We created this tangle by bringing in exotic species. Can we ever undo it? And should we even try?
You find something, something old, something with a tale to tell. Who do you call?
Stewardship land has gone from obscurity to primetime in 2022. All eyes are on a new national panel of experts, a new mana whenua panel of iwi representatives and the Minister of Conservation as they decide the fate of nine per cent of Aotearoa’s total land area—with the first million hectares to be dealt with in eight months.
With its bright-red flowers shaped like a parrot’s beak, ngutukākā—also called kākābeak—is distinctive and delicious. Only 108 plants remain in the wild in Aotearoa, but many more grow in the United Kingdom due to the efforts of an English collector and gardener in the 1830s. Now, the descendants of these plants are returning home.
Much of New Zealand’s coastal property has an expiry date, with its value set to be wiped off the ledger in as little as nine years’ time, well before sea levels rise and coastlines are redrawn. What will happen to marae and communities by the beach? And why are we still buying—and building—properties right in the danger zone?
Cats provide comfort, companionship and connection to the wild. Nearly half of all New Zealand households include a feline member. But now the country is at a crossroads—should we introduce stronger rules governing how we look after our most beloved companion animal?
In 1902, the steamship Ventnor was carrying the bones of 499 Chinese gold miners from New Zealand to southern China when it sank off the coast of Northland. For more than a century, no one knew where the ship lay. Its discovery seven years ago kindled questions and disputes that blazed into controversy earlier this year. Who decides what happens to a wreck on the bottom of the sea? And what’s the rightful resting place of men who never made it home?
What would happen if city suburbs as well as offshore islands enjoyed freedom from introduced predators? Is it possible for New Zealand to eliminate them all—stoats, ferrets, weasels, possums, and three species of rat?
Carlos Lehnebach has been looking for a ghost orchid for ten years. In July, he found one.
The hardest assignment in wildlife photography: lesser short-tailed bats.
For one fossil-fuelled week every summer, anyone can be an Invercargill motorcycling legend.
Nightfall, and the forest comes alive with squeaking. Or it used to. Lesser short-tailed bats are clinging on in a handful of places, their populations blinking out of existence. Yet researchers are only just beginning to learn about our bat species—New Zealand’s only native mammals—and what they’re finding out is pretty weird.
Retreating glaciers and thinning snow and ice are the future of New Zealand’s mountains. Climate change is predicted to warm the country’s atmosphere by 1–4°C by the end of the century, altering the natural water cycle—how much is frozen as snow, how much falls as rain, and how much flows in rivers. Climate researchers are seeking to predict what will change, and when. What will be the impact on hydroelectric power stations and irrigation schemes? Which areas will be hit hardest by flooding, or increasingly severe drought? The Deep South National Science Challenge is taking a lead role in helping decision-makers plan for the coming century.
The ocean is our playground, storehouse, transport corridor, driver of weather and coastal change. We’ve learned the hard way that it’s possible for us to exhaust its resources and overwhelm its natural processes. Now, scientists are mapping the web of relationships between the sea, the land and human industry, to figure out how fishing, aquaculture, tourism, land development, and recreation affect its health. What should be permitted, and what prohibited—and where? How can we best strike a balance between using and protecting our seas?
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.
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?
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.
Last year’s earthquake is now believed to be one of the most complex ever recorded.
The Kaikōura Earthquake was better documented and measured than any natural event in our history. As the data streams in, scientists are scrambling to decode its hidden meanings and answer some burning questions of Antipodean geology: How does seismic energy jump from one fault to another? Why were so many involved in this earthquake? And what can it teach us so we are better prepared for the next one?
