The invasive seaweed Caulerpa brachypus was discovered in New Zealand just over a year ago, and it promises to ruin everything. On Aotea/Great Barrier Island, people are sacrificing their way of life in an attempt to contain the weed—and stop it reaching the mainland.

Six parrot species are set to be banned in the Auckland region due to the dangers they pose to native wildlife. Is this fair?
A study by the Pacific Islands Forum Fisheries Agency of illegal, unreported and unregulated tuna fishing has found that the problem may not be as bad as was feared. It estimated that between 2017 and 2019, 192,000 tonnes of tuna worth more than US$300 million was caught each year in the Pacific Islands region by people not following fisheries rules—down from 300,000 tonnes in the 2016 estimate. “The assumption that unlicensed fishing is rampant has been proven false,” says Auckland-based fisheries consultant Francisco Blaha, who contributed to the report. Only five percent of the dodgy dealings involved unlicensed fishing boats. Most—89 per cent—involved licensed operators misreporting which fish they caught, or how many.
Blue sharks swim in all the world’s oceans, and a new study reveals surprising stories about their migrations and behaviour. For his doctoral research at the University of Auckland, Riley Elliott carefully attached satellite tags to 15 blue sharks—11 males and four females—in the waters off northeastern New Zealand between 2012 and 2015. With limited funding available for the expensive tags, Elliott turned to community groups and individuals, the sponsors following the animals’ movements online. In some cases, the tag stayed attached for at least a year. One shark travelled more than 14,000 kilometres from New Zealand to the Pacific Islands and Indonesia and back. Another dived to more than 1364 metres below the surface—a record at the time for blue sharks—and a third swam all the way to the equator. “We were all kind of cheering for him,” says Elliott. “The scientific theory is they don’t cross the equator.” One kilometre from the line, as though the shark had sensed it, he turned and swam south. “Unfortunately, he went through a real hotspot of tuna fishing, and we stopped hearing from him.” These long-distance travellers were all males. The tagged females remained in and around New Zealand waters all year round—a surprise, given fisheries data had suggested there were few mature females here. In a shark fairy tale, Elliott tagged a male and a female off Aotea/Great Barrier Island in 2014. The female had fresh mating scars (shark romance is not gentle), and there were young pups close by. In late summer, the male swam north to the tropics, while the female stayed around Northland. The following spring, they reunited—returning to the same spot near Aotea at the same time. Blue sharks are declining almost everywhere, as they’re caught more often than any other shark in longline fisheries. In 2019, surface longline fishers in New Zealand caught almost as many blue sharks as they did southern bluefin, the species they were actually targeting. About three-quarters of the sharks caught were killed and processed for their fins or meat.
As this issue went to print, hundreds of kororā had been found washed up dead in separate events along Te Oneroa-a-Tōhē/Ninety Mile Beach and other beaches in the Far North, in what are called penguin wrecks. The Department of Conservation says little blue penguins are dying as a result of the summer’s marine heatwave, which makes it harder for them to find food. Read more at nzgeo.com/penguins
Where do young sea creatures spend their first weeks? What’s at the root of oceanic food chains? Kelp forests are to Aotearoa what coral reefs are to other marine ecosystems. Or they used to be.
A symphony is taking place beneath the waves, as many different animals call to each other, scare off predators, stun their prey, or munch on algae. What happens when humans drown them out?
How hard could it be to find a manta ray? They’re six metres wide, after all.
Land is owned, but the sea is shared. And we haven’t been sharing very well.
What’s a wildlife photographer to do when lockdown puts an end to travel?
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?
Humans can see three primary colours. Birds can see four. What does an ultraviolet world look like? And why did birds develop the colours they wear today?
Tuna are the gold of the ocean—and, because certain species are so sought-after, they’ve become synonymous with overfishing and modern slavery. But in some areas, populations that were teetering on the edge of total wipe-out seem to be making a tentative comeback. Are things finally turning around for these fisheries?
Last century, southern right whales were hunted until there were none left—none that we could find. A small group of these whales, also called tohorā, hid from the harpoon. Deep in the subantarctic, the survivors birthed and nursed their young. Now, tohorā are returning to the coasts of New Zealand. Are we ready for them?
During winter, dozens of seabird species take flight from New Zealand on epic migrations across the planet—and recent advances in tracking technology mean we can now follow them. What we’re learning has upended scientists’ ideas about the lengths animals will go to in order to raise a family.
Old bones are a staple of museum collections, but only a handful of people in New Zealand have the skills to prepare them for display. Recovering the skeleton of a large animal—rotting it down, preparing, cleaning and articulating it—is a long and demanding journey that only the most dedicated pursue.
Hundreds of millions of years ago, mantis shrimps evolved technologies we’re still trying to copy.
The rarest bird in this country is the fairy tern, with perhaps 36 adults left in existence. It’s got everything going against it: weather, cats, its own DNA, and the fact that humans love the white-sand beaches where it raises its young. Only a small group of people, many of them volunteers, stand between it and oblivion. What will we lose if it vanishes altogether?
Are there plenty more fish in the sea? Reports of falling hoki stocks off the West Coast and the near-disappearance of crayfish from the Hauraki Gulf suggest that our ‘best in the world’ fisheries management may not be living up to the hype. Three decades ago, the right to catch and sell fish became a property right, one that has now accumulated in the hands of a few. How has that worked out for people—and for fish?
New Zealand’s forests were cleared at a record pace, and from this destruction, a sport arose: who can fell a tree the fastest? Competitive woodchopping transformed the labour of forestry into a community event. Now, 150 years on, a diminishing number of axemen and axewomen chop for top honours at A&P shows around the country.
