Utricularia dichotoma subsp. novae-zelandiae is a subspecies of bladderwort from New Zealand and New Caledonia. The taxon was defined through phylogenetic analyses by Jobson in 2020.

Utricularia dichotoma subsp. novae-zelandiae is a very variable taxon, with a large range in size, colour and shape. Generally, the plants are diminutive, growing only a few centimetres tall (although some populations reach >20cm). The flowers are usually purple. When viewed from the front, the lower petal is kite-shaped and noticeably constricted near the yellow ridges. The upper corolla lip is commonly notched at the centre and has dark veins. The nectary spur is short and broad. The bracts are usually slightly bulbous at the base, and lack a downwards-pointing spur.

This taxon arose from phylogenetic work that sampled the DNA from plants across New Zealand. All these plants were found to form a genetically similar ‘cluster’ within the larger Utricularia dichotoma grouping. These plants were therefore designated a subspecies within the U. dichotoma species concept.

Utricularia dichotoma subsp. dichotoma grows in swamps, wetlands and moist heathland across New Zealand. It is found from sea level to the alpine areas. It is most commonly encountered within open sphagnum swamps.

In nature, U. dichotoma subsp. novae-zelandiae does not occur alongside any other subspecies of Utricularia dichotoma and is unlikely to be confused. It bears a superficial resemblance to U. dichotoma subsp. monanthos, which shares its diminutive stature. It is difficult to morphologically distinguish the two taxa, although Jobson notes that subsp. novae-zelandiae often has two flowers on the scape whereas subsp. monanthos usually has one.
