At present, animal research facilities were housed in university departments.
The facility would benefit the public by advancing research in areas including cancer, diabetes, obesity, fertility and neuroscience, he said.
Construction was scheduled to start in August and be completed in February 2018.
The facility would provide the "highest standard of care" for the animals used in research, Dr Blaikie said.
"The Research Support Facility will provide an environment to meet that care, complementing the stringent ethical criteria applied by the university to all animal research before it is initiated and including the principles of reduction, replacement and refinement where possible."
The latest technology offered at the facility would also enhance animal welfare and husbandry, he said.
The new building would not mean a rise in the number of animals involved in research, or animal research staff.
Figures from 2012 show more than 25,000 animals died during research projects and teaching at Otago since 2009. Animals used for research include mice, rats, guinea pigs, birds and pigs.
Last year, the university attracted criticism from animal rights groups after it was discovered live pigs were shot in the head as part of a study to measure back-spatter from gunshot wounds.
Otago said using pigs helped to confirm whether a model head made for the study "successfully approximated an actual human head".
