Whineray said the move wouldn't alter the NZS relationship with its three existing active New Zealand share managers, Milford Asset Management, Devon Funds Management and AMP Capital.
"But [The move to in-house active management] does reduce the risk of relying on external managers," he said.
However, several industry insiders have indicated AMP Capital was set to lose its NZ Super equities mandate while Devon and Milford would retain their roles.
If so, AMP would join the growing list of local managers who fired by the Super Fund, which has included Fisher Funds and Brook Asset Management. The financial chair-swapping is also par for the course in the investment industry.
AMP Capital has itself been the beneficiary of a portfolio rethink at its sister company, AMP Financial Services (AMPFS). For example, AMPFS has removed Milford Asset Management from its list of underlying managers recommended by the group's financial advisers, putting AMP Capital in charge of the money (believed to be about $100 million, an amount, strangely enough, close to its NZS mandate).
