First collected from New Zealand by the Cunninghams in the 1830s. It is an eastern Australian species associated with sea bird nesting sites and coastal dune field, it is also indigenous to Norfolk Island. It is dispersed by sea birds common to Australia and New Zealand and is commonly found in their nests. In New Zealand it has never been particularly widespread but where it occurs is mostly on offshore islands – and in remote sea bird nesting grounds along the coastline of the northern North Island.
