The rules can be confusing though, and there are different ways of running your KiwiSaver to make sure that you're getting the most out of it.
So I put out the invite – what are the questions you want answered about your KiwiSaver?

For this podcast, I talked to Dr Claire Matthews, associate professor from Massey Business School.
