Cossar said students studying tourism and hospitality at Toi Ohomai played a key role in filling the positions.
"The business wouldn't operate in the highly skilled areas, without migrant labour, including international students, because we simply don't have these people in Rotorua."
He said one of Te Puia's long-term employees originally came to Rotorua to study and was now a key member of the IT staff at Te Puia.
"We sponsored him and his wife, who were both working for us at the time, for permanent residency. He's a great example of someone who came as a student to become a highly valuable and highly paid net contributor to our economy," Cossar said.
Another former international student who works at Te Puia in marketing, helped the tourist destination make connections with Asian countries through her language skills and understanding.
Cossar said international students, turned employees, fit in well and added "welcome diversification" to the workplace.
"Some of our migrant workers at Te Puia, who have come through education, are highly active in social groups, rotary clubs, and other things. They're giving back, because New Zealand has given them an opportunity."
In the report, Education New Zealand chief executive Grant McPherson said international students brought a raft of benefits to the country, including a $4.5 billion economic contribution.
He said they also provided a chance for New Zealanders to develop cultural awareness.
Other benefits outlined in the report were money spent on domestic travel, job creation and alumni as ambassadors.
"International students have the potential to make a significant contribution to business in their host country," the report said.
"Including international students in communities and classes is an essential part of global education."
