Abstract Cylindrospermopsis raciborskii is a
planktonic freshwater cyanobacterium that is becoming increasingly prevalent
in water bodies worldwide. During a survey of toxic cyanobacteria in New
Zealand, C. raciborskii was identified in a sample collected from
Lake Waahi (Waikato). This is the first identification of this species in
New Zealand. Liquid chromatography-mass spectrometry and liquid chromatography-tandem
mass spectrometry were used to confirm the presence of the cyanotoxins cylindrospermopsin
(CYN) and deoxy-cylindrospermopsin (do-CYN). Detection of CYN and do-CYN
demonstrates that C. raciborskii is a now a species of concern in
recreational, stock drinking, and potable water supplies in New Zealand.
