Mr Ellis did acknowledge there would likely be a reduction in the number of community newspapers in cities such as Whangarei, which has two competing mastheads.
He said the potential merger was about gaining efficiencies, which would lead to contraction within the industry.
"There will be job losses, there's no doubt about that," he said.
However, Dr Ellis said the merger was not a precursor to print media or radio about to disappear.
"Some industries have endured sustained severe downsizing and then recovered by adapting and becoming different," he said.
He points to industries such as coach building as well as aspects of the steel industry and others. Dr Ellis suggested that future for print media did not look that strong.
"Printing and distribution costs are onerous - it makes no sense to chop down trees and truck newspapers to consumers when there is a low cost digital platform available."
Both companies are being valued as part of the process and there is pressure on each to perform financially and retain or grow circulation over the next few months. A Commerce Commission decision will take four to six months.
