Portland Island (New Zealand)

Portland Island (also known as Māhia Island) is a small island located off the eastern coast of the Māhia Peninsula, in the Hawke's Bay Region of New Zealand's North Island. It is situated approximately 8 kilometers (5 miles) offshore. The island is relatively flat, reaching a height of about 128 meters (420 feet) at its highest point.

Historically, Portland Island played a significant role for Māori, with evidence of settlements and cultivation. Its Māori name, Māhia Island, reflects this deep connection to the land.

The island is known for its lighthouse, the Portland Island Lighthouse, which has guided ships navigating the often-turbulent waters off the coast since its construction in 1878. While the original lighthouse was manned, it is now automated and managed remotely.

Portland Island is an important habitat for various seabirds and marine life. Efforts have been undertaken to manage and protect the island's biodiversity, including pest control programs. Access to the island is typically restricted to protect its fragile environment and archaeological sites. Visiting often requires permits or organized tours. The island forms part of a wider protected marine area.
