It occupies temperate, Subantarctic and Antarctic oceans. Multiple calling populations have been detected around New Zealand. It is a fast swimmer that lunges through krill or schooling fish. It travels alone or in small groups.

The southern fin whale is a Migrant nationally. Historical whaling caused major declines. There is no reliable mainland site. Subantarctic voyages and deep-water crossings east of the South Island occasionally encounter it.
