About Us

History and origins

Veritaxa Limited is a New Zealand registered company. It’s mission is to realise the global commercial potential of intelligent imaging systems applied to high value niche applications in science, public health and industry. 

Veritaxa uses licenced technology developed at Massey University of New Zealand. The ‘Classifynder’ technology platform consists of robotic and optical technologies to locate microscopic particles of interest in natural samples combined with machine vision and mathematical classifiers to classify (identify) those particles.

The origins of the Classifynder technology are the pioneering studies and publications of Professor John Flenley, and the systems engineering skills of Professor Bob Hodgson, both of Massey University, New Zealand. Along with a number of PhD and Masters students and staff, the technology has been developed and prototyped over more than 10 years. Read the detail in John Flenley’s paper.

Veritaxa Limited is based in Palmerston North, New Zealand
