"... there will be no change to the team who look after your money and answer your emails and phone calls," KiwiBank says in its note to members.
However, the bank does hint at "some other changes to the scheme" that should be made public by the end of March.
According to Tracey Berry, acting CEO says the "other changes" include an upgrade from monthly to weekly pricing. Berry says while the Kiwi Wealth scheme won't be "unitised in the sense the industry understands it", the switch to weekly pricing offers more flexibility for members.
The change in pricing methodology may also ease the proposed transfer of members from KiwiBank's other, AMP-managed KiwiSaver scheme.
Berry says discussions with the Financial Markets Authority (FMA) on effecting a bulk transfer of members of the KiwiBank AMP scheme - which has been on hold for a couple of years - are "progressing well".
Meanwhile, KiwiBank and a number of other KiwiSaver providers, are awaiting the government's default scheme decision, which is due at the end of March.
According to industry insiders, the FMA has been focused on screwing down default contenders on fees - forcing some providers to question whether it's worthwhile.
But, as one source put it, what bank would be likely to turn down a default appointment on the grounds it couldn't charge enough?
