Key Research Group operates market research and call centre businesses. Its services include Pulse Business Solutions, a full-service call centre company with 85 Computer Assisted Telephone Interview (CATI) stations in Tauranga and Oamaru.
Key Research Group was founded in 1993 in Tauranga to provide strategic market research services for private and public-sector businesses, and has grown substantially since being bought as a small boutique company by Mr Hooker more than a decade ago.
It won the AUT Business School's Excellence in Support Award for companies in the $5 million - $10 million revenue sector last month.
The company said the acquisition further advanced the global expansion plans for the Key Research Group.
Research Panel has Western Australia's largest online research panel, CATI and face-to-face fieldwork offering and also provides panel group recruitment and facilities, said Key Research.
QOR was established in 2009 and is focused on providing consumer and business online panels for research purposes. Its chairman, Brian Fine, said although QOR's management of Research Panel had been relatively short, the company had helped improve the quality of the fieldwork and delivery of accurate data.
"The decision to sell was a difficult one as we had developed a strong emotional attachment to both the team at Research Panel, as well as the WA market."
The management team will stay in place. Research Panel became part of the Key Research Group from October 1.
