Self managing KiwiSaver?
Unfortunately you cannot self manage KiwiSaver. You have to invest in an approved scheme. There is a scheme called Smartshares which invests in a couple of ETF's (smartFONZ and smartMOZY). Depending on your investment balance the fee is either 0.85% or 0.65%. You can find the investment statement here. Otherwise Craigs Investment Partners offers a personalised scheme but that will sting you 1.25% in brokerage and 1.25% in custodian fees.
