Sunsuper has entered into a new agreement with global software firm SunGard, investing in the firm's recordkeeping and administration software.
"We are currently making significant investments in technology ... and this new agreement with SunGard is another step forward in supporting a more personalised, tailored service for members," Sunsuper chief executive Tony Lally said.
"Quicker enquiry response times, better web technology with a more efficient online service, as well as a raft of new online self-service features are just some of the services to be facilitated as part of the deal."
Sunsuper would not disclose how much it had invested in the technology upgrade.
The industry fund is also finalising its recent acquisition of fund administration business CSA Retirement Services, formerly CitiStreet Australia.
CSA Retirement Services will change its name to Precision Administration Services from January 31, 2009.
The rebranding is a result of the takeover of the company by Sunsuper in October this year.
It is the second name change for the company in less than six months. In September this year, the company changed its name from Citistreet Australia to CSA Retirement Services after it was acquired by ING Group.
CSA has provided administration services to Sunsuper for the past eight years. It is now a wholly-owned subsidiary of the super fund, and employs 650 staff in offices in Brisbane, Melbourne and Sydney.
Sunsuper has more than a million members and had $13 billion in funds under management as at June 30, 2008.
