Pittosporum obcordatum, commonly called Heart-leaved Kohuhu, is a species of plant in the Pittosporaceae family. It is endemic to New Zealand. The plant exists in few locations in the North Island and The Catlins only. Pittosporum obcordatum was discovered by Étienne Raoul in 1840 in Akaroa, but could then not be found again on Banks Peninsula for 170 years. It was rediscovered by Melissa Hutchison in 2012 in Okains Bay, and confirmed by local botanist Hugh Wilson.
