Mana Island Scientific Reserve is a 217-hectare predator-free island lying 2.5 kilometres off the Porirua coast northwest of Wellington. Managed by the Department of Conservation as a scientific reserve, it serves as a key site for ecological restoration and threatened species recovery. Day visits are possible via authorised charter or private boat, with landing restricted to specific hours and locations. Walking tracks cross the island, offering views and opportunities to observe native wildlife under strict biosecurity rules. The island supports ongoing conservation work including wetland restoration and seabird translocations.

About Mana Island
Mana Island was farmed for over 150 years before becoming a scientific reserve in 1987. Mice were eradicated between 1989 and 1992, making the island predator-free as rats had never established there. Extensive replanting and wetland restoration have returned much of the island to native forest and wetland habitat.
The island plays an important role in threatened species programmes. Shore plover (tūturuatu) have been translocated from captive breeding, along with takahe, North Island robin, brown teal and yellow-crowned kākāriki. Seabird colonies are being established through chick transfers, supported by sound attraction systems and artificial burrows. Lizards such as McGregor’s skink, goldstripe gecko and Cook Strait giant wētā have also benefited from the absence of mammalian predators.
Historic features include a restored woolshed with displays, a lighthouse site and a concrete gannet colony structure built to attract breeding seabirds. The scientific reserve classification prioritises conservation and research while allowing limited public access under controlled conditions.
Mana Island Tracks and Walking
Several walking tracks cross the island, providing access to viewpoints, the restored Waikoko Wetland and historic sites. A popular loop trail covers much of the island and takes several hours to complete at a relaxed pace. Tracks are generally easy to moderate, passing through regenerating forest and open grassland areas maintained for takahe.
Visitors must follow biosecurity protocols, stay on marked paths and respect all wildlife. Self-guided brochures are available, and guided tours can be arranged through authorised operators. Overnight stays are not permitted.
Wildlife and Conservation
Mana Island supports a growing range of native species thanks to predator eradication and habitat restoration. Returning seabirds act as ecosystem engineers by enriching soils and creating burrows used by lizards and invertebrates. Ongoing work includes further plantings and species translocations as habitats mature.
The island is closed to general public access outside authorised day visits to minimise disturbance and biosecurity risks. All conservation activities are coordinated by DOC in partnership with iwi and community groups such as Friends of Mana Island.
What Visitors Often Say
Day trips provide a rare chance to explore a working scientific reserve with regenerating forest, wetland birds and introduced species such as takahe. Walks offer good views back to the mainland and a strong sense of the island’s conservation focus.
Visitors appreciate the guided or self-guided options that highlight restoration efforts and wildlife sightings while stressing the need to follow strict landing and biosecurity rules. The experience feels special because of the limited access.
