Sorry, no etymologies found.
The Waitangiroto River is the only place where kotuku breed in New Zealand, although they are also present in Australia.
For example, the Waitangiroto Nature Reserve was established in 1957 to protect the kotuku nesting area and the 30 km2 Saltwater Ecological Area protects one of New Zealand's largest unmodified estuaries and the surrounding swamp forest.
Many wetland birds thrive here, including the Australsian bittern (Botaurus stellaris poiciloptilus) and the magnificent white heron or kotuku (Egretta intermedia).
