In November 2018 the Department of Conservation classified Opacuincola cervicesmadentes as Nationally Critical under the New Zealand Threat Classification System.[1] The species was judged as meeting the criteria for Nationally Critical threat status as a result of it occupying a total area of less than 1 hectare. It is found only in one location and is also classified as Data Poor under that system.[1]
