Yesterday, the forensic and data science company announced the money was raised through a funding round led by London venture capital firm Highland Europe.
The news was welcomed by Business South chief executive Mike Collins, who was "absolutely thrilled".
"This scale of investment shows confidence in their capabilities at a local level to deliver on an international stage."
Last year, Oritain was named the supreme winner of The Grand Business South Awards, after winning the excellence in science and technology award.
The company was created 15 years ago by Prof Russell Frew and Dr Helen Darling at the University of Otago and had become a global leader in using forensic science to determine product provenance.
Its science could pinpoint the exact area a product or raw material came from, within metres.
While it now had offices in Washington, Switzerland — where chief executive Grant Cochrane is now based — London and Auckland, Dunedin remained its headquarters.
When asked if there was any tangible effect from the funding on the Dunedin operation, a spokeswoman said nowhere was the company’s continuing global expansion more visible than its Dunedin headquarters.
"With more amazing staff and a full-scale renovation to our premises already well under way, we are delighted that our business is continuing to attract and retain such great talent in our spiritual home."
The company had compound annual growth of 90% year-on-year over the past six years and, in January, attracted former prime minister Sir John Key to join its board.
Clients included luxury high-end fashion and retail companies, including Lacoste, Supima and Primark, and food producers Nescafe and a2 Milk.
Mr Cochrane told RNZ the funding would help Oritain open up and diversify through research and development which was all done in New Zealand, and develop new products to sell to brands overseas.
In an interview with the Otago Daily Times in May, Mr Cochrane said the company had about 170 staff and about 50 job positions ready to go.
While 80% of Oritain’s revenue was offshore, there was no reason to move from Dunedin.
There was a great team in its office and a great relationship with the university, he said.
In a statement, Oritain said fraud and counterfeiting, exacerbated by increasingly fragmented global supply chains, cost the global economy more than $500 billion annually.
Environmental issues such as deforestation were also increasingly top of investor and customer concerns which could damage brand reputations built up over decades.
Oritain provided data-driven insights to help producers and manufacturers to monitor and adapt their supply chain to safeguard and improve transparency and certainty for its clients.
Highland Europe principal Jacob Bernstein would join Oritain’s board.
