But Ian Purdy of ACC fired back at Scott's board accusing them of being bad managers who should leave.
ANZ was not involved in managing property anywhere else in the world and badly-performing managers should not get a big payout, Purdy said.
Tim Storey, DNZ chairman, hit back at Argosy accusing it of lacking transparency in its management and objecting to the media accusation.
"We didn't give an undertaking but we thought it appropriate matters were discussed directly rather than through the media," Storey said.
He implored investors to reject the internalisation proposal and consider alternatives, forcing the board to commission a comprehensive independent report explaining all the alternatives and financial benefits of a new path such as another manager taking over, a process which could be achieved quickly.
"It's only then we will be in a position to make a proper decision," Storey said.
"This process has been characterised by vigorous and hostile responses from the manager but I don't want to get into petty debate," Storey said.
He also asked investors to consider why they would think of paying $20 million to have precisely the same managers, same governance team and same directors in charge of Argosy.
