Ms Jackson said human cell lines could be cultured outside the body, including in petri dishes, and in some cases some human body structures could also be developed outside the body. Her organisation believed that using such human resources for research was more morally and scientifically responsible than undertaking animal experiments.
An Otago University spokesman said the university "recognises that there are different views on this matter, but believes that animal-based research is a vital component for important medical and scientific advances".
Claims of animal mistreatment at Otago University were "outrageous and unfounded", the spokesman said.
"All animal-based research undertaken at Otago goes through a strict ethics approval process and is carried out as humanely as possible.
"The care and treatment of animals housed in our facilities is of the highest standards and is undertaken by professional staff who take their animal welfare responsibilities very seriously.
"Animals are only used in research or teaching if there are no appropriate alternatives. Cell lines, human-based research or computer simulations are used extensively in place of animal research at the university where possible," he said.
