jonherries:gzt: The question on the figure is not about rounding up or down.
Does that figure represent the total value of recorded music sales in NZ or something substantially different?
In any case, it is clearly not the total value of music purchased in NZ because the figure does not include iTunes and Amazon sales to users in NZ but that is a different question again and not related to the first directly.
According to RIANZ it is the value of "the market" whatever that means. I assume it is all the royalties they collect on behalf of local and international artists?
Exactly. Yes, whatever that means. You are forced to make assumptions because they provide no details. RIAANZ is a media company association. You are getting confused with organisations like APRA who represent the interests of artists. Click 'single page' and search this thread for APRA for earlier comments on that important difference.
