The Most Remarkable Rock Formations in New Zealand
6 places · updated 14 October 2026
In short: By our ranking, the most remarkable rock formations in New Zealand are Moeraki Boulders / Kaihinaki, Pancake Rocks and Castle Hill. The list covers 6 rock formations. Last updated 14 October 2026.
New Zealand rides the boundary of the Pacific and Australian plates, so seabeds have been lifted into hills and coasts within geologically recent time. That uplift exposes rocks that formed under the sea, while heavy rain and surf carve them quickly, and the result is a country where limestone, mudstone and gravel take shapes found almost nowhere else.
The Moeraki Boulders on Koekohe Beach in Otago are near-perfect spheres, some around 2 m across, that grew as concretions in seafloor mudstone millions of years ago and are now washed out by the waves. The Pancake Rocks at Punakaiki are layered limestone stacks, with blowholes that spout at high tide. The Ōpārara Arch in Kahurangi National Park is a great limestone span over a river in dense forest. The Pūtangirua Pinnacles in the Wairarapa are eroded columns of gravel that served as the Paths of the Dead in The Lord of the Rings.

01 Moeraki Boulders / Kaihinaki
New Zealand · 29.4 km from Oamaru45.345° S 170.826° E
Image by Simon from Pixabay The boulders are best seen around low tide, when more of the beach is exposed and you can walk among them, and at sunrise, when the light comes straight off the Pacific and the wet spheres shine.
Did you know? Besides calcite, the cracks inside the boulders contain small amounts of dolomite and quartz.
02 Pancake Rocks
New Zealand42.117° S 171.327° E
Image by Makalu from Pixabay The rocks lie within Paparoa National Park, next to the small village of Punakaiki, which sits between the mouths of the Pororari and Punakaiki rivers. A loop of paths winds among the formations, out to viewing platforms above the blowholes and surge pools. Early gold-rush travellers, who crossed this headland on the coastal route in the 1860s, left no record of the extraordinary rocks just off their track.
Did you know? The blowholes work like pistons: incoming waves trap and compress air in sea caves, blasting air and water up through openings in the roof.
03 Castle Hill
New Zealand43.229° S 171.716° E
Michal Klajban · CC BY-SA 4.0 The outcrops lie on high-country station land and inside the Kura Tāwhiti Conservation Area, and over the past decades they have become one of the best-known bouldering areas in New Zealand, their rough, pocketed stone drawing climbers from around the world. Neighbouring Flock Hill station, with a similar field of boulders, served as the backdrop for the climactic battle in the 2005 film The Chronicles of Narnia: The Lion, the Witch and the Wardrobe. A popular story holds that the Dalai Lama, on a visit to New Zealand in 2002, called Castle Hill a spiritual centre of the universe, and the phrase has followed the place ever since.
Did you know? The limestone formed on an ancient seabed roughly 30 to 40 million years ago.
04 Ōpārara Arch
New Zealand41.145° S 172.188° E
Stewart Nimmo · CC BY-SA 4.0 The basin is also a site of global importance for fossils. The cave system of Honeycomb Hill, explored in the 1980s, has yielded the largest collection of bird fossils found in New Zealand, including the most complete remains of the extinct Haast's eagle and nine species of moa. Today the forest is home to great spotted kiwi, blue duck and kea, and to giant carnivorous land snails found nowhere else.
Did you know? The Honeycomb Hill cave system has about 70 entrances and roughly 13 km of passages, inventoried by the Buller Caving Group in the 1980s.
05 Mount Sunday
New Zealand43.548° S 170.893° E
Jeff Hitchcock from Vancouver, BC, Canada · CC BY 2.0 Its modern fame comes from Peter Jackson's The Lord of the Rings. Location scouts flying over the valley picked the hill as Edoras, the hilltop capital of Rohan, and the crew spent months building a road, houses, stables and the Golden Hall of King Théoden on the summit. After filming in 1999 the whole set was dismantled and the land returned to its natural state, so nothing of Edoras remains. Yet even without it, visitors who recognise the silhouette from The Two Towers find the scene instantly familiar, and the hill lies within Hakatere Conservation Park, where a short track climbs to the top.
Did you know? The hill is a roche moutonnée, carved asymmetrically by the Rangitata Glacier during the ice ages.
06 Pūtangirua Pinnacles
New Zealand · 39.1 km from Upper Hutt41.447° S 175.246° E
Simeon W from Wellington, New Zealand · CC BY 2.0 The formation lies within a scenic reserve managed by the Department of Conservation, where a track follows the Pūtangirua Stream bed and then climbs to a lookout on the ridge above the pillars. The eerie landscape served as a film location for the Paths of the Dead sequence in The Lord of the Rings: The Return of the King and for the opening of the film Braindead. In December 2019 the name Pūtangirua Pinnacles was officially gazetted for the formation.
Did you know? Filming conditions also required the horses to come from stables free of gorse and broom, two invasive weeds.
How this list is ranked
Places are chosen for how they look, not for how famous they are: each one has its own description and a photograph credited to its author. The order is a single world ranking that weighs the beauty of the place in curated photography together with how widely it is documented — the number of language editions of its encyclopedia article and how often that article is read in a year. The list is rebuilt as places are added, so the order and the counts on this page are always current.
Questions people ask
- What are the most remarkable rock formations in New Zealand?
- On our list, Moeraki Boulders / Kaihinaki ranks first, followed by Pancake Rocks and Castle Hill.
- How were the Moeraki Boulders formed?
- The boulders are concretions that grew slowly around a core within mudstone on the ancient seafloor, cemented by calcite. Coastal erosion of the cliffs behind Koekohe Beach releases them onto the sand.
- Why do the Pancake Rocks look layered?
- The Pancake Rocks are limestone formed from layers of marine organisms and softer mud on the seabed. After uplift, weathering removed the softer layers faster than the hard ones, leaving stacks that look like piles of pancakes.
- How many rock formations are on this list in New Zealand?
- The list covers 6 rock formations.
