It would be good if historical unit prices for KiwiSaver were available. On your website you have a tool that can search up unit prices up to a year ago but not before 11/2/2013 (A non binding constraint)
Can you publish graphs of unit prices over time on your website and within internet banking so this information is readily available to customers.
I think you need to be more open about the results so that customers can get an understanding of how KiwiSvaer is performing.
Would it be possible to make weekly unit prices available for download, all the way back to bnz starting their KiwiSaver scheme
