Pourewa Island, Coastal island in Tolaga Bay, New Zealand

Pourewa Island is a 42-hectare island at the southern edge of Tolaga Bay on New Zealand's North Island east coast. With the Mitre Rocks opposite, it forms the entrance to Cook's Cove, where James Cook anchored the Endeavour on 23 October 1769 to take on fresh water and supplies.

The island was named Spöring Island by James Cook in 1769 during his voyage aboard HM Bark Endeavour, after Finnish draughtsman Herman Spöring. This naming reflects the connections between European exploration and the individuals who participated in these journeys.

Pourewa Island was inhabited in Cook's time, and Māori sources record that the high-ranking woman Hinematioro lived there; she died in 1823. In 1885 a carved figure used as house-panel decoration was found in the mud, and local Māori identified it as belonging to Hinematioro's house. A related object said to be her gift to botanist Joseph Banks is held at the Institute of Ethnology in Tübingen.

Pourewa Island is a 42-hectare island at the southern edge of Tolaga Bay, and together with the Mitre Rocks opposite it forms the entrance to Cook's Cove. There is no regular boat service, so access depends on arranging a private craft and on sea conditions at the bay mouth. The island is not a landing site for the cove's walking track.

Hinematioro, a high-ranking Māori woman said to have lived on the island, died in 1823. In 1885 a carved figure used as house-panel decoration was found in the mud; local Māori linked it to her house.
