It’s just a hill with a view, right? Wrong. If you’ve ever stood on the windy summit of One Tree Hill Auckland, looking out over the narrow neck of the North Island, you’ve likely felt that weird, heavy sense of history that a standard city park just doesn’t have. It’s Maungakiekie. It’s a tomb. It’s a battlefield. And, since the year 2000, it’s a hill without an actual tree.
You’ll see tourists hopping off buses, squinting at the massive stone obelisk, and asking where the tree is. The irony isn't lost on locals. But the story of how this volcanic peak became the soul of the city—and why there’s currently a bunch of young totara and pōhutukawa growing in a cage at the top—is way more intense than most travel blogs suggest. This isn't just a photo op; it’s a site of deep-seated Māori heritage and a very visible scar of New Zealand’s colonial friction.
The Massive Scale of Maungakiekie
Most people call it One Tree Hill, but its original name is Maungakiekie. It translates to "mountain of the kiekie vine." Back in the day—we're talking 18th-century heights—this wasn't just a park. It was the largest indigenous fortification (pā) in the entire Southern Hemisphere. Estimates from historians like Dr. R.C.J. Stone suggest that at its peak, several thousand people lived on these slopes.
Think about that for a second.
The terraces you see today? Those aren't natural geological formations. They were hand-dug. Every flat ridge where you might want to pitch a picnic blanket was once a living platform, a storage pit for kūmara, or a defensive trench. The Waiohua iwi (tribe) transformed a volcano into a literal city. When you walk up from the Cornwall Park side, you’re basically walking through an ancient, vertical metropolis.
It's huge. 182 meters high. From the top, you can see both the Waitematā and Manukau harbors. If you were a chief 300 years ago, this was the ultimate strategic high ground. You could see enemies coming from either ocean hours before they arrived.
Why Is There No Tree on One Tree Hill Auckland?
This is the question that haunts the Auckland visitor center. The short answer? Politics and a chainsaw.
Originally, there was a sacred totara tree at the summit, which gave the hill its Māori name Te Puke-o-Taramainuku. That tree was cut down by a European settler in the 1850s, allegedly for firewood, which is pretty much the most depressing metaphor for colonization you could invent. Sir John Logan Campbell, the man who eventually gifted the land to the city, tried to replant a grove of trees to replace it, but only a single Monterey Pine survived.

That pine became the "One Tree."
But in the 1990s, it became a target for Māori activists, most notably Mike Smith, who attacked the tree with a chainsaw to draw attention to government injustices against Māori. The tree survived the first attack in 1994 but was struck again in 1999. By 2000, the tree was a dying safety hazard. The council had to cut it down.
For sixteen years, the summit was bald.
Honestly, it looked weird. Aucklanders felt like something was missing from the skyline. It wasn't until 2016 that a new grove of native trees—totara, pōhutukawa, and tōtara—were planted during a dawn ceremony. They are currently surrounded by a massive windbreak and cage to protect them from the brutal winds and, well, people. They’re growing, slowly. One day, one will be chosen to remain as the "One" tree, but nature takes its time.
The Ghost of Sir John Logan Campbell
You can’t talk about One Tree Hill Auckland without mentioning the man buried at the top. Sir John Logan Campbell is often called the "Father of Auckland." He loved this hill so much he wanted it to be his final resting place.
His grave sits right under that 30-meter-high obelisk.
The obelisk itself is a bit of a contradiction. Campbell intended it to be a permanent memorial to the Māori race, which at the time, many Europeans mistakenly thought was "dying out." It’s a massive, towering structure that dominates the skyline, but it was actually funded by Campbell’s estate and completed long after he died. It wasn't unveiled until 1948 because of delays from World War II.

Standing at the base of the obelisk is a bit surreal. You’ve got a Victorian-era merchant’s tomb, a monument to a "vanishing" people who are very much alive and thriving, and 360-degree views of a modern, bustling city. It’s a lot to process while you’re trying to keep your hat from blowing off.
Cornwall Park vs. One Tree Hill
People use the names interchangeably, but they’re different things. One Tree Hill is the volcanic cone. Cornwall Park is the lush, green estate that surrounds it.
Sir John Logan Campbell gifted the parkland to the people of New Zealand in 1901 during a royal visit by the Duke and Duchess of Cornwall (hence the name). The cool thing? It’s managed by a private trust, not the city council. This is why it feels different from other parks. It’s immaculately maintained. There are cows. There are sheep.
Yes, literal sheep in the middle of New Zealand’s biggest city.
In the springtime (September and October), the park is full of lambs. It is probably the only place in the world where you can take a suburban train to a park and find yourself in the middle of a working farm. It’s sort of surreal to see a lamb frolicking with the Sky Tower in the background.
Practical Tips for the Ascent
If you’re planning to head up there, don't just put "One Tree Hill" into Google Maps and hope for the best. There are some things you should know.
- No Cars at the Top: Since 2018, the road to the summit has been closed to private vehicles. This was a move by the Tūpuna Maunga Authority to show respect to the spiritual significance of the site. You have to walk.
- The Hike: It’s not Everest, but it’s a bit of a puff. It’ll take you about 15 to 20 minutes from the base of the cone to the summit. Wear decent shoes. Flip-flops (jandals) are a bad idea if it’s been raining.
- The Wind: It is always, always windier at the top than you think it will be. Even on a hot summer day, bring a light jacket.
- Acacia Cottage: Stop by this little wooden building near the main park entrance. It’s one of Auckland’s oldest surviving houses, built in 1841. It looks like a dollhouse compared to the mansions in nearby Epsom.
The Geological Reality
Auckland sits on a volcanic field of about 53 volcanoes. Maungakiekie is one of the big ones. It last erupted about 67,000 years ago. Geologically speaking, it’s a scoria cone with three craters.

When you stand in the middle of the main crater, you can actually feel the temperature drop. The acoustics change. It’s quiet. It’s a massive natural amphitheater that once held thousands of people. Today, it’s mostly home to some very confused-looking cattle.
The lava flows from this volcano actually created a lot of the flat land you see in the surrounding suburbs of Onehunga and Royal Oak. The rocks used for the dry-stone walls throughout the park? That’s all volcanic scoria from right under your feet.
Why it Matters in 2026
In recent years, the management of Maungakiekie has shifted. It’s now co-governed by the Tūpuna Maunga Authority, representing 13 iwi and hapū. This shift is part of a larger movement in New Zealand to return the "mana" (prestige) to these ancestral mountains.
You’ll notice more signage in Te Reo Māori. You’ll notice a focus on native replanting. The park isn't just a relic of the colonial past anymore; it’s a living piece of bicultural Auckland.
There’s a tension here that’s worth acknowledging. Some people miss being able to drive to the top. Others feel the obelisk is an eyesore. But that’s what makes One Tree Hill Auckland interesting. It’s not a sterile tourist park. It’s a place of friction, history, and incredible beauty.
How to Get the Most Out of Your Visit
If you want to do this right, don't just run to the top and leave.
- Start at the Stardome: The Stardome Observatory is located at the southern end of the park. Even if you don't go inside, the area around it is great for seeing the old lava flows.
- Walk the Rim: Instead of just standing by the obelisk, walk the entire circumference of the summit. You get different views of the city from every angle—Rangitoto Island to the east and the Waitākere Ranges to the west.
- Picnic in the Olive Grove: There’s a grove of olive trees planted by Campbell that feels like you’ve been transported to the Mediterranean. It’s much more sheltered than the summit.
- Respect the Tapu: Remember that for Māori, the summit is a sacred site. Don't climb on the graves or the monuments. It’s basically an outdoor cathedral.
Actionable Next Steps:
- Check the Weather: Use the MetService app specifically for Auckland Central. If the cloud cover is below 200 meters, you won't see anything from the top.
- Timing: Aim for "Golden Hour"—the hour before sunset. The way the light hits the terraces of the hill makes the ancient Māori earthworks pop, creating shadows that reveal the true scale of the old pā.
- Transport: Take the train to Greenlane Station. It’s a 10-minute walk to the park gate. It beats fighting for a parking spot on a sunny Sunday.
- Supplies: Grab a coffee at the Cornwall Park Bistro near the playground before you start the climb. Their scones are legendary among locals, but watch out for the seagulls; they are bold and have zero respect for your personal space.
