I did ask NZPost about this, as they appear to have more info internally, and they said they are working on making more details public. But this was at least a year ago... so idk if it'll happen.
Yeah I went through the NZ Post investigations process, and they apparently weigh the package multiple times as it makes its way through airports (also multiple scans I presume).
I would definitely appreciate it if more information could be displayed on the tracking page.
