Rāhui was produced during Emily Karaka’s time living and working at Parehuia as the first McCahon House Artist in Residence of 2021. As the title indicates, the show centres on the concept of a rāhui, a prohibition that excludes people from an area where a tapu has been placed. The rāhui maintains and safeguards the mauri—or life force—of the area, entities within it, and the people. Karaka makes special reference to the rāhui placed on Te Wao Nui a Tiriwa, the Waitākere forest, by Te Kawerau ā Maki (one of her iwi) in order to protect it from ‘kauri dieback’. She draws a parallel between this disease and the present pandemic, emphasising that mātauranga Māori offers strategies for comprehending and counteracting the substantial environmental and health crises that we are facing.
