Dozens of the curious Moeraki Boulders are grouped in clusters along Koekohe Beach near the village of Moeraki. These enormous, spherical and veined rocks seem like ominous pods from a sci-fi movie. They average three to over six feet high. The largest is ten feet in diameter. They are 60 to 65 million years old. Geologists have a detailed explanation for how they were formed. It is boring and dilutes their mystery. Māori tradition explains them as gourds from the shipwrecked Āraiteuru canoe, the legendary vessel used by Polynesians to discover New Zealand.
