This seahorse is found in the south-west Pacific around Australia and New Zealand (2). It is known in Australia from Newcastle, New South Wales southwards, throughout Victoria, Tasmania and westwards as far as the northern Great Australian Bight in South Australia (9). In New Zealand, it is widespread around both North and South Islands (3). It has been suggested that the populations that make up this species are actually two separate species. However, this taxonomic splitting is still quite contentious and there is little evidence for the existence of two species (10).
