These nine giant green shells at Kumutoto Wharf were created by sculptor Michael Tuffery in 2012. They portray kina, a sea urchin endemic to New Zealand. This public artwork titled “Nga Kina” is a tribute to the Māori settlement that once lived at this point (Kumutoto Pa) where the Kumutoto stream emptied into the harbor. It now flows beneath an underground tunnel. Kina were fished and eaten by the Māori people for centuries.
