In July 2023 four male kākāpō were released into the fenced Sanctuary Mountain Maungatautari – part of a new habitat trial to investigate suitable locations for the growing kākāpō population. But after a further six were introduced, the kākāpō began to wander – beyond the fence. A year on, and several escapes later, what’s been learned? And what’s next for kākāpō in Maungatautari?

There are plenty of night-time wanderers in New Zealand that you might expect to come across driving on back roads – rats, mice, a seemingly endless number of possums.

But it’s not often that you round a corner to come face to face with a kākāpō.

Elwin’s escapade

This was the surprising sight that faced Tyler James Lindsay very early one morning in January 2024.

A Cambridge local, Tyler was driving a milk tanker along Scott Road, northeast of Sanctuary Mountain Maungatautari, when suddenly he saw before him a strange shape.

“Just a big green bird. Just in the middle of the road looking straight at my lights, I think it was rather confused,” he says.

Luckily, Tyler is into native birds, so he was aware that kākāpō had been introduced to the fenced sanctuary six months earlier. He knew exactly what he was looking at.

The next day, Tyler’s report made its way to Sanctuary Mountain Maungatautari kākāpō ranger Dan Howie, who quickly began the search for the elusive Elwin.

“Such an incredible interaction that he saw this bird out there – in the middle of the road no less – which is absolutely terrifying as kākāpō ranger,” says Dan.

But this was not the first time, nor the last, that Dan would feel that fear.

The habitat trial

Kākāpō numbers are growing. In 1995 there were just 51 kākāpō and the threat of losing them forever was all too real.

A decade ago, around the time that Dr Andrew Digby joined the Kākāpō Recovery team, there were just over 120 kākāpō. Today there are 247.

Intensive management and three quite successful breeding seasons have enabled this doubling of kākāpō numbers in the last 10 years. Initially, the challenge was to save the charismatic, flightless parrots from extinction. Now, the team also has an added challenge: where to put them.

To date, the majority of kākāpō have lived on offshore predator-free islands in the rohe of Ngāi Tahu – Whenua Hou / Codfish Island next to Rakiura / Stewart Island, and Pukenui / Anchor Island in Fiordland. But these islands are getting full…
