The recent NZS review conducted by consultancy firm, Promontory says the fund's in-house NZ active equities unit, established in November 2013, should be able to "add value relative to the passive mandate".
According to the Promontory report, as at May this year, the NZS in-house team managed about $526 million of local shares.
"... (a part of this has been managed passively and a part actively, with the actively managed part increasing steadily over time), with a further $890m by the three external managers (representing approximately 5% of the Fund and around 2.4% of the NZX50 index capitalisation)," the report says.
However, Promontory also notes the NZS should be aware that "executing a substantial equity or derivative transaction in a small market (e.g. New Zealand equities) can result in shifting the market".
Adding in the AMP mandate would take NZS in-house local equities portfolio over $750 million.
However, Etheredge, says transferring the AMP portfolio to the in-house team would not impact share prices as NZS already owned the underlying securities so no trading was necessary.
Potential replacement managers are no doubt polishing off their NZS pitches with a few obvious contenders coming to mind such as boutique NZ funds firms Harbour, Mint, Salt, Castlepoint and Forte (run by ex AMP manager, John Phipps). Even Fisher Funds might give it another crack despite losing an NZS mandate in 2008.
