Trust House would be charging for providing tenancy management services for the group, which would generate extra revenue for the community-owned business, Mr Pollard said.
"There's obviously a fee for services so there would be more surplus profits for the community, and working with such a large asset management company, we might actually learn and develop some more intellectual property ... and in the long run we could develop a stronger operational model."
Working with, and learning from a very large housing provider would help give Trust House more experience and "more grunt", Mr Pollard said.
Accessible Properties, which is owned by IHC, and Hapori Connect Tauranga are the other two organisations shortlisted.
Hapori Connect Tauranga is a consortium made up of British-owned Pinnacle Community Housing, Canadian real estate management company Brookfields Global Integrated Solutions, and the John Laing Infrastructure Fund, which is listed on the London Stock Exchange.
Mr Pollard said he hoped the fact the Kainga consortium had a "real Kiwi element" would give it an edge.
The move also fits with Trust House's aspirations to grow its social housing portfolio, he said.
"We are really keen for the government to start releasing other housing in the lower North Island."
Fully costed proposals are due by June 7.
The preferred bidder for each region is due to be announced between June and September.
