ING Investment Management deputy chief executive Martin Donnelly has left the firm as part of a restructure.
Donnelly worked for the firm since October 2007 and was in part responsible for the distribution of the business.
In May, the firm expanded its resources in the wholesale market, appointing Jim McKay as head of wholesale business, responsible for distribution.
"We were a bit heavy on our marketing and sales capabilities. I thought it was appropriate to restructure the team. Given that Martin was also a deputy chief executive, it was a role we no longer required," ING Investment Management chief executive Steven Billiet said.
Billiet said the firm had re-organised its capabilities to focus on investment.
ING Investment Management recently made hires to its business, including a spate of new appointments in its property, small companies and credit research teams in August.
The restructure has also meant the establishment of a Melbourne office, staffed by two sales people.
"We will continue to recruit to our business. We are looking to build more sales teams for our Melbourne and Sydney offices," Billiet said.
