This site introduces one of those community groups:
These groups are working to help save the brown kiwi – specifically the form known as western brown kiwi.
Kiwi sanctuaries and mainland islands
Of the five kiwi sanctuaries managed by the Department of Conservation, the one closest to the Whanganui/Manawatu area is at Tongariro.
The Department also manages six mainland islands where introduced pests are intensively managed to help protect native species. While one is in the Whanganui/Manawatu region – Paengaroa mainland island – it doesn’t have kiwi. The nearest mainland island with kiwi is Boundary Stream, in Hawke’s Bay.
The closest places to see captive kiwi are the Nga Manu Trust, Waikanae, and the Pukaha Mount Bruce National Wildlife Centre, in the Wairarapa.
The nearest opportunities to see wild kiwi is at Zealandia, in Wellington city.
You may also see kiwi if you volunteer to help the local kiwi groups.
