Paphies australis or pipi (from the Māori language) is a bivalve mollusc of the family Mesodesmatidae, endemic to New Zealand.

[2] Pipi are edible and easily collected for food; traditional cooking methods include boiling and making into fritters.

The harvest limit in New Zealand is 50 per person per day, and although a minimum size is not stipulated in the regulations, only larger pipi should be taken.

For Māori, pipi are a traditional food resource, and in earlier times were gathered in specific flax baskets made for this purpose.

Smaller specimens would fall between the woven strips and back into the beds to grow as the basket was gently swirled through the water.
