The changes are the result of revised vision statement goals the fund has developed and implemented in the past 18 months.
The fund has hired CommInsure to manage its income protection and retained Hannover Life as its group insurer.
Christian Super is currently assessing whether to offer its members more insurance products.
"Part of our mission goals developed recently was to build new products. We are looking to broaden our insurance and offer more insurance products," Christian Super chief executive Peter Murphy said.
The fund has also boosted its investment team, hiring three people.
It hired Peter Hawkes, Sam Forrest and Emma Stewart as a credit and alternative analyst, ethical research analyst and investment analyst respectively.
The hires were also part of Christian Super's revised goals, which included an investment strategy that was consistent with its "Christian focus", Murphy said.
The fund's ethicist, Gordon Preece, will ensure the fund continues to implement an ethical investment approach.
Following the implementation of its investment strategy, the fund moved 50 per cent of its fixed income portfolio in-house and invested 50 per cent of the remaining portfolio to seed the establishment of the AMP Capital Investors Responsible Investment Leaders Diversified Fixed Income Fund.
"We see our investment strategy, which also includes an ethical focus, as being a differentiator for us," Murphy said.
"Our fund is values based, which resonates with our members who also have similar Christian values as ourselves."
