The toheroa has long been a popular seafood, often made into a greenish soup, for which it has an international reputation.

Toheroa were translocated across New Zealand by Māori using pōhā (kelp bags) made from southern bull kelp (Durvillaea poha).

It was over-exploited in the 1950s and 1960s, and there has been a ban on harvesting (except for limited customary purposes) since 1979.
However, numbers have not recovered since 1979, due to illegal poaching, poorly policed customary harvesting, vehicle driving on beaches, pollution, reduction in fresh water coming onto beaches, and gas bubble disease.
