CSG has won a five-year, $9 million outsourcing contract with the Northern Territory Government-owned insurance and banking firm TIO.

CSG will handle all of TIO's infrastructure, networking and voice systems, including Windows-based systems and IBM AS 400 servers.

The deal will allow CSG to engage in both of its strengths — printer management and ICT services — according to the company.

"By outsourcing to a supplier with greater capability and skills than what we have in-house, TIO can improve our IT systems in a cost-effective and sustainable way," TIO general manager corporate services Jeff Wright said in a statement.
