Oasis Asset Management has appointed its majority shareholder, ING Australia, to provide its group insurance.
It replaced Tower Australia after an external tender process.
Oasis managing director Wayne Lowe said the firm chose ING because of its competitiveness.
"ING Australia was chosen due to the strength of their service offering and underwriting practices," Lowe said.
ING Australia bought 73 per cent of Oasis from Pacific Equity Partners in March 2006.
