The New Zealand flatworm is a non-native species, first recorded in Great Britain in Edinburgh (1965), but now widely distributed throughout much of Scotland and, to a lesser extent, northern England.

A Code of Practice has been produced for this and other non-native flatworms in GB. This is a practical guide to help producers and traders of nursery stock detect and limit the spread of non-indigenous flatworms, notably the 'New Zealand' flatworm, Arthurdendyus triangulatus, and the 'Australian' flatworm, Australoplana sanguinea.
