Molecular-based approaches for harmful algal bloom species, which can be difficult to identify by light microscopy, are important tools for detecting and predicting the blooms. In this study, 84 samples from Aotearoa/New Zealand coastal waters that contained  Azadinium -like cells were analysed using an Amphidomataceae real-time PCR assay. Nineteen samples were positive, and 24  Azadinium -like clonal isolates were established from these samples. Subsequently, only five isolates from one sampling point were positive using the real-time PCR assay. Four of the five isolates were genetically identified as  Amphidoma languida  and one as  Azadinium dalianense . The field samples were analysed retrospectively using the species-specific real-time PCR assays;  Am. languida  was detected from the temperate areas, while  Az. poporum  and  Az. spinosum  were detected at one site. Two representative strains of each species were analysed by liquid chromatography-tandem mass spectrometry (LC-MS/MS), including  Am. languida,  which is known as toxic in the previous studies, but neither produced the currently monitored azaspiracids (AZAs). These two newly recorded species for New Zealand are important findings. The results highlight the need for more information on the spatio-temporal variations of potentially toxic Amphidomataceae species and the risk of AZAs in New Zealand coastal waters.
