Angeline Ngahina Greensill (born 1948) is a New Zealand Māori political rights campaigner, academic and leader.
Between 1984–1996 while raising her young family, she worked for her hapū as co-ordinator of employment and skills training and conservation programmes for youth in the Raglan Catchment area.
As an advocate for the protection of the environment [3] and for Maori land rights of West Coast whānau and hapu in the Whaingaroa area since the mid-70s, Greensill's legal efforts have been crucial in helping to block human-cow transgenic field trials being conducted by AgResearch Ltd, and helped to educate Māori communities on the implications of genetic engineering.
Due to her expertise[citation needed] in this field she was interviewed in the documentary film The Leech and the Earthworm by Max Pugh and Marc Silver.
Greensill unsuccessfully stood for the Māori Party in the Maori electorates of Tainui and Hauraki-Waikato in the New Zealand general elections of 2005 and 2008 respectively.
