Current conservation status
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2017 using the New Zealand Threat Classification System (NZTCS). This report includes a statistical summary and brief notes on changes since 2012 and replaces all previous NZTCS lists for vascular plants. Authors: By Peter J. de Lange, Jeremy R. Rolfe, John W. Barkla, Shannel P. Courtney, Paul D. Champion, Leon R. Perrie, Sarah M. Beadel, Kerry A. Ford, Ilse Breitwieser, Ines Schönberger, Rowan Hindmarsh-Walls, Peter B. Heenan and Kate Ladley.

Similar taxa
The NZ species in the genus Gonocarpus can be distinguished by (adapted from A.E. Orchard, 1975, Taxonomic revisions in the Family Haloragaceae, Bulletin of the Auckland Institute and Museum 10); G. montanus: primary floral bracts opposite (at least in lower part of flower), fruit 8-ribbed (with 2-3 calluses between ribs), leaves opposite, appressed hairs on young parts, sparsely so on base of midvein on underside of leaf; G. aggregatus similar but fruits 4-8 ribbed (and without calluses), leaves hairy on both surfaces; G. incanus: primary floral bracts alternate throughout, fruit +/- ovoid, 8-ribbed with 2-3 calluses between ribs, stems with appressed hairs; G. micranthus similar but primary bracts are deciduous, stems are glabrous, and fruit is nodding and without the callusses between ribs. Plants intermediate between G montanus and G. incanus are known.
