Main image

Cuvier Island (Repanga) is an uninhabited island in the Hauraki Gulf off the east coast of New Zealand’s North Island, administered as a nature reserve for seabirds and native vegetation. The island is managed for conservation and has no general public facilities.

The island supports native coastal forest and important seabird colonies; it is known for predator-free restoration work and for breeding seabirds that use offshore islands in the Hauraki Gulf. Visits are limited to protect nesting birds and to maintain biosecurity.

European-era structures include a lighthouse and small historic buildings related to its past use for navigation. The island is managed by the New Zealand Department of Conservation as a wildlife sanctuary and biosecurity is strictly controlled.

Cuvier Island sits in the outer Hauraki Gulf in the Waikato region, off the eastern seaboard of the North Island, east of the Coromandel Peninsula. It is several tens of kilometres offshore and isolated from the mainland by open Gulf waters.

  • Access restrictions: Landing and visits are restricted and generally require permission from New Zealand conservation authorities to protect breeding seabirds and sensitive habitats.

What to See #

  • Lighthouse: A historic lighthouse stands on the island and marks shipping routes through the Hauraki Gulf; the light installation is a visible built feature though the island has no permanent population.
  • Nature reserve: The island is managed as a wildlife sanctuary and is important for breeding seabirds and for the conservation of native forest once introduced pests were removed.
