When Paul Ward first suggested bringing kiwi back to the hills around Wellington, people thought he was mad. He heard it in woolsheds and village halls, in farm kitchens and on marae. The idea — restore New Zealand's beloved national bird to a landscape it hadn't inhabited for more than a century — sounded like a conservationist's fever dream.

On April 28, Ward and his team will celebrate the release of the 250th kiwi into the wild, marked by a special pōwhiri at Parliament. It is a milestone that belongs not to one man, but to an entire city.

From backyard traps to a 24,000-hectare sanctuary

The Capital Kiwi Project began modestly in 2018. Ward and a handful of neighbours had been trapping rats, stoats, and ferrets in the Waimapihi Reserve after native birds — kākā and tīeke — started spilling over the fence from the Zealandia eco-sanctuary into unprotected territory.

"If you can have a bird like the kākā come back, could we bring back our national symbol, our taonga?" Ward asked.

Within a year, 70 community trappers had joined. Within six years, more than 4,600 traps covered 24,000 hectares of wind-swept hill country on Wellington's fringes. The project brought together mountain bikers, trail runners, four-wheel drivers, mana whenua, and families — a citizen army united by a single, improbable ambition.

"There was this profound shift from guardianship being something a DOC ranger did somewhere far away, to something that's done by us," Ward says.

The science of survival

The kiwi's great enemy is the stoat — a wily predator introduced in the nineteenth century. Without pest control, fewer than five in every hundred kiwi chicks survive to adulthood. The Department of Conservation required Capital Kiwi to demonstrate stoat detections in no more than five per cent of tracking tunnels, measured quarterly, for three consecutive years before any birds could be released.

The team deployed a network of DOC 250 and Goodnature A24 traps, but encountered an unexpected problem: hedgehogs kept triggering them. The team's science advisor, Dr Christine Stockum, led research that produced an elegant solution — raising each trap just ten centimetres off the ground. Hedgehogs, reluctant climbers, were deterred. Stoats, agile by nature, were caught in even greater numbers.

"It's not a silver bullet," Ward says, "but it's an example of getting to know your landscape, paying attention to its signals."

In 2022, the first kiwi walked Wellington's hills in over a hundred years. Today, more than 200 roam free — and crucially, they are breeding. A chick named Maui, hatched on Terawhiti Station in late 2024, recently made "fight weight," growing large enough to fend off stoats with his sharp raking claws. The project's target was for 30 per cent of the first 20 monitored chicks to reach 1.2 kilograms. They hit that mark from just the first seven.

"The rate at which our chicks are reaching stoat-proof weight is, pun fully intended, beyond our wildest expectations," Ward says.

More than numbers

What sets Capital Kiwi apart is its deep partnership with local iwi and its embrace of Te Ao Māori perspectives. Traditional conservation removes eggs and rears chicks in captivity. Capital Kiwi's approach is the opposite: restore a landscape where kiwi can breed, raise their young, and establish territory naturally — preserving the whakapapa connection between parent and chick.

"From a Te Ao Māori perspective, you've severed the whakapapa connection between the chick and the parents," Ward explains. "Our response is restoring a large-scale population to the wild where they can do all those things naturally."

The human impact has been just as profound. Wellington's dawn chorus now rivals that of the country's national parks, according to Ward. The project has drawn coverage from The New York Times and National Geographic, and Ward was recognised as a Nature Hero alongside Jane Goodall.

A city transformed

The 250th release is a celebration, but it is also a proof of concept. It demonstrates that conservation need not be the province of distant rangers in remote forests. It can happen on the hills above a capital city, driven by ordinary people who decided to act.

"Having a bird like the kiwi living back in our lives means we experience their mana," Ward says. "We're not separate from nature. We're living with nature."
