These groups are working to help save the brown kiwi – specifically the form known as eastern brown kiwi.
Kiwi sanctuaries and mainland islands
Of the five kiwi sanctuaries managed by the Department of Conservation, the one closest to the East Coast is at Tongariro.
Two of the Department’s six mainland islands are near the East Coast area – Northern Te Urewera and Boundary Stream. These are places where introduced pests are intensively managed to help protect kiwi.
The closest place to see captive kiwi in the East Coast region is the National Aquarium of New Zealand in Napier.
You may see kiwi if you volunteer to help the local kiwi groups.
