Depending on whom you read, the story of Kakapo in Nelson tends to be a footnote in Kakapo research papers.

For most of us, that seems unsurprising. After all, the story of Kakapo as presently told is one where extinction happened rapidly across New Zealand, and the species was almost exclusively confined to Fiordland by around the 1940s. There they seemingly faded out in the 1980s and have most likely been extinct ever since.

Nelson isn’t even a footnote. It’s a virtually blank slate. So what if I told you there’s a significant body of evidence to suggest that Kakapo survived in Northwest Nelson (more commonly called Kahurangi National Park) into the last few decades? And that understanding their extinction in Nelson might better help us map extinction for Kakapo and other species across New Zealand.

Across all the mainstream literature I’ve read about Kakapo, the following information exists. Don Merton, Ralph Powlesland, and John Cockrem, in their 2006 paper "A Parrot Apart: The Natural History of the Kakapo (Strigops habroptilus), and the Context of Its Conservation Management," simply note that "the species became extinct in the North Island and in northwest Nelson early in the 20th century."

While G.R. Williams, who kickstarted Kakapo conservation efforts in 1956, simply observed that "however, over about the last twenty-five years there seem to be no reliable records of Kakapo having been seen in the Nelson Province, although there are rumors that they still occur in some of the western mountain ranges."

Nelson is often considered a blank slate when it comes to Kakapo

Notes in the Dark : The Rabbit Hole Begins.

Two sources kicked off my interest in the topic. The first was "Quest for the Kakapo" by David Butler, a book published in 1989. Butler was heavily involved in the Kakapo searches and a methodical researcher, who was one of the few individuals to explore primary sources not explored by the Department of Conservation at the time. In his writings, he notes six stories of Kakapo being seen in Northwest Nelson between 1960 and 1985, including compelling stories from four individuals who are still widely respected in the conservation field to this day (Dr. Graeme Elliott, Kath Walker, Andy Wilshire, and Colin Roderick). These weren't backcountry users; they were conservation experts who all had a reported Kakapo story from Nelson decades after their supposed extinction in the region.

The second is a study published by Joanne Carpenter in 2023 which, from her research of a very incomplete set of information (she was reviewing digital data that hadn’t been fully completed at the time of study), suggested a modeled extinction date of 1971-1979 for Kakapo in Nelson. The piece of information that perplexed me was that the Kakapo in question was actually shot near Arthur's Pass by a deer culler in 1957. This posed a problem because the source was deemed reliable by a team of researchers; however, it sat outside the known range of the species since the 19th century! How could the last Kakapo in the top of the South Island have been found in an area they hadn’t even been known to historically exist?

These two pieces of information flew in the face of existing data. How could Kakapo possibly have existed in Nelson more than fifty to eighty years after their supposed extinction date unless there was more hidden beneath the surface?

Could Kakapo have survived into the Modern Era here?

The Ultimate Challange : A story Determined to remain untold 

Like most New Zealanders, I love a good challenge and set out to learn about the topic. I limited myself to only published information from books, newspapers, government sources, and journals. However, unlike other researchers, I don’t come from an ecology background. My background is marketing with an emphasis on data crunching, which means that when it comes to finding information online, I've built an entire business on how to find and utilize it at scale. To be clear, this information is all publicly available either online or in local government sources. It’s just that no one has ever bothered to collate it before or known where to look. It’s been a labor of love across three years, and I hope you enjoy it.

My first pit stop was determining what the known story of the final days of Kakapo in Nelson looked like. To understand that, it’s important to explore patterns of extinction in other species. Typically, across four other species (Little Spotted Kiwi, Laughing Owl, Bush Wren, South Island Kokako), final reports happened between the 1930s and 1960s in Nelson Lakes National Park, 1930s-1980s in Lake Sumner, Victoria Forest Park, Paparoas & Arthur’s Pass, and 1980s to present day in Kahurangi National Park. This was helpful because it gives us a broad date range to keep an eye out for. While there will be variables, we could reasonably expect Kakapo to follow roughly similar dates of extinction.

Similarly, in Fiordland, the last Kakapo were typically found in the head basins of U-shaped glacial valleys or on high cliff benches far above the valley floors. In the majority of instances, the elevation was 700-1000 meters above sea level. So we should lend more credence to ‘late’ stories that come from remote head basins and higher elevations.

Nelson Lakes National Park : Exploring Patterns of Extinction.

So what reports exist from Nelson Lakes National Park of Kakapo? Sitting an hour and a half outside of Nelson, Nelson Lakes National Park rises into the spine of the Southern Alps, albeit with less challenging terrain than further south. Butler records their disappearance from the area largely occurring during World War One, with Kakapo disappearing from nearby Mt. Owen around 1930.

Kath Walker, however, notes a bushman in the 1930s who commented they were still present around Lake Rotoiti, and Moncrief (a well-known author) makes some passing notes to their possible presence in the Nelson Lakes around this time (as well as sighting another in Kahurangi). Perhaps most notably, a final report was made by Ross Wylie of the Nelson branch of the Forest Service in 1946 of seeing a Kakapo in the Nelson Lakes between Lake Rotoroa and the Howard Valley on a spur about 500 meters elevation.

So was that the final story of Kakapo in Nelson Lakes? Mostly gone by World War One, but with a handful of birds surviving until just after World War Two? The patterns we see of extinction suggest that they may have held on longer. A keen observer would note that all sightings come from lower elevations in the park near the lakes themselves. The last Bush Wren, for example, was sighted nearly two decades later in 1968 right in the glacier U-shaped D'Urville and Sabine valleys nearly fifteen kilometers away at the true limit of the park before it rises into the spine of the Southern Alps. Wouldn’t we expect the final Kakapo stories to come from here?

I believe it’s helpful to remember that the absence of evidence isn’t evidence of absence; oftentimes, it just suggests our records are incomplete. We’re talking about deeply inhospitable terrain, looking for a species that is nigh on impossible to find due to its camouflaged nature. Two stories exist after this date that are worth noting. Both are from hunters and not published, so while not carrying the same weight, they are worth mentioning.

The first is from a Nelson family (who have asked to remain nameless for now) who reported that their father, who was an experienced bushman, had seen a Kakapo at the end of the Nelson Lakes in the early 1960s. He reported it to the Department of Internal Affairs, who sent a letter back that he still has. Several searches were apparently made, but a blank was drawn. While no DOC records exist, this is unsurprising as the entirety of Kakapo research from the Lands and Survey Department from this period is presently unable to be located in government archives.

The second is from a private message from an old hunter who has declined to be named or interviewed but who was adamant Kakapo were present ‘at the end of Nelson Lakes’ in the 1960s. In isolation, it’s not much to go by, but it fits with a broader picture of extinction in the area and, given he was unaware of the other information in this article, it’s worth noting if nothing else.

The last verified Kakapo in Nelson Lakes National Park were found at the end of these lakes in the 1930's and 40's.

Down South : Prospectors, Poaching and the Paparoas

So what next in our story of extinction? Well, let’s take a dive into the sighting that kicked this all off. A Kakapo supposedly from near Arthur's Pass in 1957 which records state was killed by a deer culler. I found an old interview with a deer culler named Harry Scott that referenced the story. But to find the full account, I had to submit an official information act request to the Department of Conservation, who released an interview with Mike Bennett, a well-known deer culler who was familiar with Kakapo from South Westland. He seems to think the story happened in 1958 (a year different than Harry Scott), but both were interviewed thirty to forty years later, so it’s likely a case of not recalling exactly which year.

Mike explains that they were hunting near Jacksons in the Haipu Block as deer cullers, and ‘another culler’ (he remains mum as to who it was in his party) shot a bird on dark, mistaking it for a Kea. The Wildlife Service allegedly became involved and asked the cullers to keep it quiet as they had been illegally hunting on the flats near the Jacksons highway close to the Taramakau River, and they were concerned that a scandal might arise. The story in isolation seems almost fantastic. Hundreds of kilometers away from any other known source, a Kakapo is shot in an area they’d never been recorded by a group of hunters at a low elevation. Were it not corroborated by multiple witnesses familiar with Kakapo, it’d be thrown out as lunacy.

Or would it?

The Road to Arthur's pass. It was on flats similar to these that a Kakapo was shot in 1957/8

Historical Clues : Digging deep into West Coast History

Because G.J. Roberts, the Crown Commissioner of the land, noted in a 1907 report that Maori could remember Kakapo in the Bealy, Waimakariri, Otiria, Hurunui, Taramakau, and Rakaia Rivers and that in some places they were still present. G. R. Williams also corroborates that in the 1880s, Kakapo had been present. But this was fifty years later on the river flats. How could Kakapo have still been present?

The first clue is Mike Bennett himself, who commented in 1989 that while hunting above the bushline on the Taramakau River that same year, he found Kakapo feeding sign above the bushline on Mt. Howe & Mt. Alex. He was quite familiar with the species and observed their decline along with South Island Kokako in South Westland, and if one sighting by him can be accepted as true, there’s no reason to believe he lied about the second.

But we must consider the terrain. The West Coast is an isolated place, and the terrain is extremely rugged. Glacier U-shaped valleys are common, and the bushline here is well in excess of 1500 meters elevation. Few people live in the region, and my own experience of them (as the son of a former West Coaster) is that they’re very wary of outsiders. Was it that Kakapo were not present? Or that they were just never studied here well? Again, absence of evidence is not evidence of absence.

Past papers record that two prospectors reported a Kakapo ‘West of Lake Sumner’ in 1922. While Williams, in his 1956 account of Kakapo, provides a footnote confirming he had received a record of a Kakapo in the Robinson River in Lake Sumner Forest Park in 1925. A third record also exists from David Butler’s research from the Lewis Pass in 1937. Another record from a Bill Bennett (possibly a relative of Mike) exists from 1989 when he spoke of Kakapo in the Ahaura River Catchment in the late 1950s. Finally, Butler reports that road workers on the Lewis Pass found Kakapo present in 1964.

All of this paints a small but picture of isolated fragmented remnant Kakapo largely at extreme elevations in the area from the 1920s to mid-1960s. However, what was the state of the population? A handful of birds spread across several hundred square kilometers? How do you account for one still surviving on the river flats in the late 1950s when historically they vanish from lower elevations long before they do at extreme elevations?

Punakiki provides a firsthand example of the primeval legacy the Paparoas hold  

Across the Ranges : The Secret Lies in the Paparoas

Across the ranges in the Paparoas may hold the answers. This primeval range of mountains borders behind Greymouth and sits between the Grey River to the South and the Buller River to the North. Yet here, a wealth of information exists that helps paint a picture of what the broader area may have looked like.

In 1923, a J. Drummond wrote that ‘bushmen in Greymouth reported that not far from the town in accessible but not often visited gullies Kakapo could still be found.’ Similarly, Forest and Bird Magazine noted in 1924 that ‘Large Colonies’ of Kakapo are listed as being present in the mountains near Buller,’ which provided a baseline understanding that Kakapo were common in the area at the time. Yet this proves to be an understatement. A recent comment by a senior DOC worker implied that the last Kakapo to be observed breeding on mainland New Zealand occurred in the early 1900s and that the 1930s were probably the final time Kakapo successfully bred in NZ, and even then, it would have been hundreds of kilometers south in the cold mountainous depths of Fiordland.

Yet in 1947 or 1948, while prospecting east of Punakaiki, C.E. Wilks saw two Kakapo and a chick (it’s implied the two adult Kakapo were not seen together). Wilks was intimately familiar with Kakapo, having previously reported them in Glenorchy, Lake Sumner, and now near the Paparoas. It’s worth noting that this was not the main spine of the Paparoa mountains but seemingly in the vast and treacherous criss-crossed network of gullies suitable for prospecting prior to reaching the mountains. Wilks would note that the last Kakapo he saw in the area was in the Paparoas themselves in 1955.

The Punakaiki record is corroborated by another record of a Kakapo behind this area from 1958 by another prospector on the coastal side of the Paparoas. Yet it’s the final note in the Paparoas chapter that provides the most evidence. In 1964, a Kakapo was sighted by two tramline workers in the Rough River area of the Paparoa ranges. It was observed for several moments before it disappeared. Notably, this was on the river flats, not above the bushline.

It’s this final record that probably paints a sign of the times. We have three records of birds between 1948-1964 that were not in the spine of the Paparoa mountains but instead in the bush or on flat ground and another record from the river flats near Arthur's Pass of a Kakapo on the river flats there. None of these (though other reports exist) were above the bushline, at high altitude, or in the head basin of glacial U-shaped valleys.

Why were the last Kakapo sighted not high up in the mountains?

Pulling the threads together : When did Kakapo vanish?

When did Kakapo largely vanish from the Paparoas, Arthur's Pass, and Lewis Pass? It’s hard to say. There’s only a single historic record ever from the tops of the Paparoa mountains but plenty from the river flats and lower bush areas. I’ll keep repeating it over and over again. Evidence of absence isn’t absence of evidence. My own father worked in the area in the early 1970s and described it as largely unexplored, ‘entirely absent of people except for the occasional deer culler or prospector.’ While he never heard Kakapo, he notes he never thought to look for them either.

The area was almost entirely absent of people, and the best we can do is use the example we have from Nelson Lakes National Park that extinction probably occurred around fifteen to twenty years after birds vanished from the valley floors, suggesting a rough extinction date of the early to mid-1980s. Though this is a rough estimate at best, it’s matched by trends we see in the Tutuko Valley & Sinbad Valley, where most birds had vanished from the valley floor by the late 1960s and extinction occurred fifteen to twenty years later on the high bench & head basin slopes.

So what about Kahurangi National Park?

Well, buckle in because things are about to get wild.

Kahurangi National Park

 Kahurangi : A Hidden World of Kakapo

G.R. Williams notes Kakapo as being present in Gouland Downs and the Karamea River in the first quarter of the 19th century. While Mr. Clouston, the caretaker of Gouland Downs, noted that Kakapo were present in considerable numbers in 1923 and reportedly had a pet Kakapo observed between 1920 and 1930. So considerable were numbers in the Gouland Downs region that a number were killed for a London exhibition in 1924, while prospectors reported them as still being common in the 1930s.

It’s worth noting that this extends down to Takaka itself, which reportedly had large numbers of Kakapo present behind it in the 1930s. Corroborated sightings also came from Mt. Arthur in 1930, between the Upper Mokihinui and Karamea River in 1934, and the Wangapeka Saddle in 1934. Reports here seem to dip over the next three decades.

Only two sightings exist from this period: in 1953, Michael Anderson and his father were hunting on Hailes Knob in the Waitui Stream near upper Takaka when they observed a Kakapo feeding in a clearing for three minutes in rugged bush. While in the mid-1950s, a Dr. Peat, likely of the Canterbury Museum, reported hearing Kakapo calls on the aptly named Kakapo River.

It’s worth noting that 1939-1945 saw the outbreak of World War Two, and in the immediate aftermath, the rediscovery of Takahe in Fiordland saw the closing of the Murchison Mountains, which deeply isolated the hunting community and made them reluctant to report sightings. The impact of this reluctance to share Kakapo information due to fear of loss of access cannot be overstated and is corroborated by a series of articles written by NZ newspapers during this period of time where hunters bemoan not being consulted by the Wildlife Service and offer to show the Wildlife Service where Kakapo lived if their hunting grounds were not entirely closed down.

For nearly two decades Kahurangi kept her secrets close

Wildlife Service Expeditions : Fatal Mistakes

The Wildlife Service commissioned a major expedition in 1958 which spent fourteen days combing Gouland Downs in poor weather searching for Kakapo with a young dog. Rather perplexingly, the party ‘determined’ that it was unlikely Kakapo had ever been present in large numbers this century. They further went on to write that Clouston had probably exaggerated the presence of Kakapo, and upon their advice, further expeditions were largely cancelled.

It’s worth digging into this for a moment. In the 1960s in Fiordland, more than 1000 man-days were spent in the field and only a handful of Kakapo were found. Yet official estimates place the population in Milford Sound at 100-200 birds at this time. When searching for the Kakapo male Richard Henry in 1975, it took ten days combing an area of just a few hundred meters where he was known to be present to catch him. The idea that Kakapo were entirely absent from a 5000-square-kilometer area because a team couldn't find them during fourteen days of poor weather is a ludicrous assumption that seems to have hamstrung efforts to locate Kakapo in the area after this point.

It highlights the importance of methodical, well-funded research over a large period of time, rather than one-off research trips by individuals not well accustomed to the area. It wouldn’t be the last time this caused problems for Nelson Kakapo. One final record comes from this period, though it wouldn’t emerge for some decades. Snow Meyer, the old NZ Forest Service Ranger from Kahurangi National Park back when it was a state forest, is corroborated by a number of witnesses as having spoken about a Kakapo being present on the Karamea River. He repeatedly told a number of trampers in the 1980s that the old male was booming from Garibaldi Ridge near Karamea Bend Hut during the 1950s and early 1960s. Snow was both a legend in the area, and given his wealth of expertise, there’s no reason to doubt this record.

 

Snow Meyer last heard a Kakapo booming in the Karamea in the 1950's & 60's.

The Heaphy Track & Mt Arthur Tablelands : A Final Refuge

The 1960s brought with them a renewed volume of Kakapo reports, in part because of both the creation of the North West Nelson Forest Park in 1965 and the rediscovery and restoration of the Heaphy Track. While on Mount Arthur, geological surveys appear to have stumbled across a number of Kakapo.

The restoration of the Heaphy is of particular note because of a spate of sightings over a short period of time. A Ministry of Works team reported a Kakapo on the Heaphy Track in 1967. The following year, a former NZ Defense Force member and family reported seeing another Kakapo on the Collingwood side of the Heaphy Track. While a third sighting was made not far away in the Iwitiuaroa Range of the Mackay Downs in Kahurangi National Park south of Rocks Point. A fourth possible sighting was reported to a local paper in 1970.

The sightings don’t end there. Robyn Allan of Nelson recalls his father heard them in the 1980s while repairing huts up in Gouland Downs. While Colin Roderick, who actually worked with Kakapo at Mount Bruce, reported hearing booming in Gouland Downs in 1978. An active track and bowl system was also reported by Kath Walker and Dr. Graeme Elliott in 1982.

It’s worth focusing on this for a moment. This was one of the first well-restored ‘great walks’ throughout remote New Zealand, and its opening seems to have coincided with a sudden increase in Kakapo sightings. In my estimation, it’s also the nail in the coffin of the report a decade earlier in the same area suggesting Kakapo no longer were present. Instead, I’d argue it’s a sign that Kakapo were still present at least intermittently across the medium-altitude Gouland Downs.

Gouland Downs shares many similarities with southwest Stewart Island. It sits at about six to eight hundred meters altitude on a cold, wind-swept mixture of tussock tableland and an impregnable hedge of native bush. It wasn’t until 1918 that stoats were even recorded here, almost twenty-five years after they were first recorded in Fiordland.

Kakapo seem to last be found on tablelands such as these. It’s worth noting that the other location of many sightings, Mt. Arthur, has similar tablelands but at higher altitude. In fact, tablelands across the country are a common theme in late Kakapo sightings, with Lake Fraser Tablelands in Fiordland being the location of three 1960s Kakapo sightings. Anecdotally, I’ve had several hunters claim that Kakapo were present until the 1970s on the Stockton Tablelands. Lending credence to this is the recent rediscovery of Haast Tokoeka on the Cascade Tablelands in South Westland.

Similar to Gouland Downs, the Mount Arthur Tablelands saw a Kakapo sighting in 1972 and then another in 1983 when two birds were heard booming on the tablelands, and feeding sign from a third bird was found further along the tablelands. It’s worth noting that both the 1972 and 1983 sightings were in the exact same location near Salisbury Hut. While at the base of the tablelands, Dr. Miles Hursthouse would report seeing a Kakapo near Leslie River and Peel Stream in 1978.

Gouland Downs is home to the Heaphy track.

Scattered Reports : Kakapo across Kahurangi 

Across the park, a Canterbury caving team allegedly reported a Kakapo booming from above the Buller River in the early 1970s. While a team reportedly recorded a Kakapo booming above the Karamea River in the 1980s, the recording was later lost. Neither of these reports has been corroborated, though, and should be treated with a degree of skepticism.

More authentic reports include two sightings of Kakapo in the Castles area of Aorere Valley, one in 1974 and the other in 1981. The 1981 sighting was by Kath Walker, one of the leading experts on insect life in New Zealand today. She ended up being involved in a significant number of Kakapo searches and wrote a fifty-page report on Kakapo in North West Nelson that I obtained from old government archives through an official information act release. Elsewhere, F.S. Biddle reported Kakapo calls from the head of the Ugly River in 1976. While in 1987, Brian Thomas reported booming from Happy Valley Saddle near Corbyvale.

Perhaps the most notable and equally tragic part of the story of Kakapo in Nelson comes from just how close we were to saving some of them.

The mid screen Blue icon to the right indicates Mt Arthur. The Dommet and Ugly Rivers are centre left. The Karamea River lies to the bottom left.

Roaring Lion River : A Reprieve for Kakapo.

In early December 1984, a party of four reported hearing booming near the headwaters of the Roaring Lion River. One of the group, Andy Wiltshire, was an NZFS worker from Nelson who had spent a month looking for Kakapo on Stewart Island and was familiar with the species. The following month, a team of four returned with a trained dog and searched the area for five days. The party included the legendary Ron Neilson, who had significant experience working with Kakapo across Fiordland and Stewart Island and had been instrumental in saving the species.

A forty-page report privately commissioned by the Wildlife Service details that two active track and bowl systems were found, both of which had recent feeding signs nearby. While nearby, a third possible track and bowl system and feeding sign were discovered too, though it was partially damaged by rain. Ron Neilson himself confirmed that he firmly believed the track and bowl systems had Kakapo present, and the Wildlife Service released an internal memo that they wanted the first captured Kakapo to be called ‘Andy’ after Andy Wiltshire. It’s worth noting that the track and bowl systems were both around 1200 meters elevation, as were the two reports from Kath Walker. The Mount Arthur sightings were at 1200 meters elevation, while the calls in the Ugly River were heard at 1000 meters elevation but were immediately next to a 1200-meter elevation ridgeline. Even the Happy Valley Saddle sighting, while at a lower elevation, was on a ridge extending from Mount Connor, which sits at 1257 meters elevation. Surely these could not be mere coincidence, but instead a theme - all locations in the 1980s where Kakapo were confidently found were at higher elevation than any Fiordland birds were found. No Fiordland bird was ever found above 1100 meters, mostly because the steep nature of the terrain didn’t allow birds to reach higher elevation, at least in areas studied. Perhaps here lies a clue. Should Kakapo remain in Fiordland, the place to look would be above 1200 meters elevation.

Yet it’s here that the story takes an odd turn. Butler notes that significant traction was gained in searching North West Nelson. Don Merton himself, in a private letter, acknowledged his belief that a population was probably present. But poor weather hampered searches, as did inexperienced staff. It’s not immediately clear as to where some things went wrong. But one report claims nearly thirty possible track and bowl systems were ‘found’ over a two-year period, most in the nearby Gouland range.

It's not hard to see how these isolated mountains could have been home to Kakapo

A Tragic End : How Budget Pressure Impacted Saving Kakapo.

But it’s this set of track and bowl systems that probably derailed research efforts across the area. Funding was a major issue; the entire Kakapo recovery program was at threat of being defunded in the late 1980s, and untrained volunteers were heavily relied upon for Nelson searches. Arnold Heine seems to have been an individual who, according to Department of Conservation records, found most of these ‘later’ track and bowl systems.

Under pressure to make cuts, a senior member of the department flew into the Gouland range and studied eight of these track and bowl systems over the course of a day. It’s notable that he chose to study only track and bowl systems found by inexperienced volunteers (Kath Walker, Andy Grant, and Arnold Heine), none of which came from the Roaring Lion River, where experienced Kakapo recovery team members had conducted their research.

His conclusion was that these eight systems were the results of a lightning strike, but in a stunning decision, he recommended that the entire Nelson program be canceled as a result of his findings in a single afternoon. At least the team in 1958 had spent fourteen days before concluding Kakapo were not present! It’s notable that he himself appears to have had no experience with Kakapo, and while it’s been forty years, a cross-reference of his name (which I’ve chosen not to publish because he appears to still be living and does not deserve the hate) to all known Kakapo documents I can find at least suggests this was his one and only piece of Kakapo fieldwork. To my knowledge, no one ever visited the active systems in the Roaring Lion River again, and the story of Kakapo in Nelson ends on a tragic footnote. All fieldwork was shelved and so well hidden that it could not be found in a search for these documents in 2021, and it took a second request in 2024 for the relevant reports to be found and released.

A tragic end to the story of Kakapo in Nelson

Painful Lessons : What can we learn from this?

The story of Nelson Kakapo seems to be a heartbreaking tale. But for government budget cuts, we might have rescued a handful of birds that would have been genetically invaluable to the modern Kakapo population. Modern Kakapo suffer deeply from inbreeding, and a single Fiordland bird, Richard Henry, represents about twenty percent of unique alleles in the population. The addition of a handful of Nelson birds would have been an incredible genetic boon.

Why then was the program not followed up? There are more reports from Nelson in the 60s, 70s, and 80s than Fiordland. I believe much of the issue lies with the 1958 party, who very publicly denounced the continued survival of Kakapo in Nelson. They had successfully found a Kakapo in Fiordland the previous year (albeit with a different, more experienced dog) and, without the benefit of hindsight, probably felt that if Kakapo were present, they should have been easy to find.

Yet by comparison, a six-week study of Port Pegasus and the Tin Range in the 1960s failed to turn up any evidence of Kakapo, despite several hundred likely being present. This was mostly due to the weather, and its impact cannot be underestimated on the 1958 search.

Additionally, there has never been a central system of collecting Kakapo sightings across New Zealand. Reports were largely made to regional offices or, because multiple government departments historically handled backcountry management, to uninterested officials who never passed on relevant information. It’s amazing how the many reports from Nelson have skeptical comments from officials in the margins. Outside of David Butler and Kath Walker, no one ever actually compiled any reports together and studied them as a whole. Even Butler and Walker both lacked the access to digital information we have today to compile a complete picture of Kakapo in the park.

We stand on the shoulders of giants who searched the park for Kakapo

The Ugly River : The Final Mystery

The story of Kakapo has one final footnote. It’s one that’s as yet unverified, but I’ve heard the story from so many separate hunters over the years that it does seem to have a grain of truth. Purportedly, in the last decade, an eccentric older Motueka hunter claimed to have found active Kakapo sign above the bushline in the Ugly River. He returned from the bush with green Kakapo feathers (which a number of hunters I’ve spoken to have been to his house and seen), feeding chews, and Kakapo droppings.

Ultimately, I’ve not been able to schedule an interview - and those I’ve spoken to have suggested I’ll be unlikely to. There’s a real sense that he’d like to not speak publicly about his experiences. Perhaps the ring of truth comes from the location itself and the elevation. The bushline in the Ugly River sits at between 1300-1500 meters, and it backs onto the other side of the mountains in the Roaring Lion River, where Andy Wiltshire found Kakapo in 1985. Both things none of the hunters would have known when they shared the story.

It fits the pattern of where you’d expect to find the last Nelson Kakapo. However, without corroboration, we’ll never know the truth. In some ways, that’s a fitting end to the story of Nelson Kakapo, a deep sense of mystery, of wonder, and that drive to get out into the remote northwest Kahurangi wilderness where the last Kakapo were found.

It’s made me want to visit again. To climb to the top of the Ugly River and camp above the bushline this coming summer. To stay up late after dark…and just listen.

Even if all that responds is silence.

It’d be worth it to experience that.

N.B Undoubtedly there is more to this story to tell. I'd love to interview Graeme Elliot, Kath Walker, Andy Wiltshire and Colin Roderick to my knowledge all of whom are still living. I'd also encourage Karamea, West Coast, Nelson locals to ask older hunters and outdoorsmen their stories and pass on any that come up.
