East Island / Whangaokeno is a small (13-hectare or 32-acre) island approximately 2 km (1.2 mi) east of East Cape in the North Island of New Zealand. Reaching an elevation of 129 m (423 ft), it was the original location for the East Cape Lighthouse, which was built in 1900. However, the island is prone to earthquakes and its steep cliffs cause numerous landslides. By 1920, the danger to the lighthouse was considered great enough to trigger a decision to move the lighthouse to the mainland.
