What are the Moeraki Boulders
The Moeraki Boulders refer to around 50 boulders on Koekohe Beach in Moeraki. Many of them are perfectly spherical with large cracks in them. About two-thirds of the boulders are the size of 1.5-2.2m in diameter. With the backdrop of the sea, these geological oddities have become a popular photo stop on the South Island.
How were the Boulders formed?
While there is no solid explanation for how the Moeraki Boulders were formed, the most common belief is that they formed on the seabed around 60 million years ago through a process called concretion. Since the land has risen from the sea, the waves have eroded the soft mudstone surrounding the bounders, exposing and releasing the boulders onto the beach.
The Maori legend of the Moeraki boulders
In Maori legend, the boulders represented the remains eel, kumara and food baskets that washed up on the shores after the legendary waka (canoe),Araiteuru, wrecked off the nearby shores of Shag Point (Matakaea).
