Stephens Island (New Zealand)

Stephens Island, also known by its Māori name Takapourewa, is a small island in New Zealand waters noted for its lighthouse and for conservation interests linked to seabirds and reptiles. It is particularly well known in conservation history for the dramatic loss of a small flightless bird species in the late 19th century.

The island’s principal features are the lighthouse precinct and the wildlife areas that support seabird colonies and reptile species such as tuatara where management and eradication of introduced predators have been priorities. Landings are limited and normally require permission because the island functions as a protected reserve.

A lighthouse was established on the island in the late 19th century and the island became infamous when a small endemic wren species was driven to extinction after predators were introduced during that period. Management since the 20th century has focused on protecting remaining native fauna and preventing further invasive species impacts.

Stephens Island lies in Cook Strait off the northern coast of the South Island of New Zealand and is administered as part of the Marlborough region.

• Conservation status: The island is known by its Māori name, Takapourewa, and is legally protected as a wildlife sanctuary with restricted public access to protect breeding birds and reptile populations.
• Lighthouse history: A lighthouse constructed in the late 19th century operated on the island and is central to its modern history and early human impact on native fauna.

What to See#

• Lighthouse precinct: A historic lighthouse station and its associated structures sit on the island; the site is closely linked to early lighthouse operations and keeper residence remains.
• Wildlife reserve: Protected bird and reptile habitats managed as a nature reserve, including translocated or managed populations of native species and seabird colonies.

Access is by private boat or charter from ports on the northern South Island (services arranged from Picton or nearby harbours). Landings are weather-dependent and usually require prior permission from the landowner or Department of Conservation; there are no scheduled ferries.

• Arrange transport with a licensed charter from the Marlborough Sounds - private landing is required and seasonal restrictions may apply.
• Respect wildlife: the island has sensitive seabird colonies; keep distance and follow DOC or local guidelines.
• Bring foul-weather gear: conditions in Cook Strait can change rapidly; expect strong winds and spray.
