And that's an interesting little comment, which deserves an asterisk and a footnote.
Because the aggregate KiwiSaver statistics, published by the IRD, show that a large proportion of auto-enrolled members have made an active choice since first being shunted into a default fund.
According to the IRD stats, from the 2007 launch of KiwiSaver until the end of April this year 986,003 members have been automatically enrolled into a default scheme. But as at the end of April the IRD records only 556,061 members in default-allocated funds.
Based on mathematics, that shows almost 44 per cent of those originally defaulted into a KiwiSaver scheme have since made an active choice - an incredible statistic.
The IRD figures don't show whether auto-enrollees shift to a different fund offered by the original provider (probably not) or when they make the choice.
But perhaps the very act of auto-enrolment prompts some members to shift elsewhere, in the spirit of 'no one tells me what to do'.
The numbers also give a hint as to why providers struggle to move-on the rump default members.
With the easily-activated defaultees already shifted, what remains are the pathologically-disengaged, the conspiracy-theorists, the unsaveable, the right-at-homes and the GNFAs (gone-no-forwarding-addresses).
