NZ Seafood
Toheroa (Paphies ventricosa) is a large surf clam that was once NZʻs most famous shellfish — Heinz even produced canned toheroa soup in the mid-20th century. Overharvesting devastated the population and toheroa has been fully protected since the 1980s. It cannot be legally harvested. Toheroaʻs inclusion in Provenance is as a cautionary tale: the most famous NZ shellfish was destroyed by overconsumption. The Māori principle of kaitiakitanga (guardianship) exists precisely because of histories like this. When Provenance talks about sustainability, toheroa is the example of what happens when you donʻt practice it.
