[sacrosancty]

It's possible to be both not public enough to ruin people's lives and public enough for journalists or concerned individuals to find. In New Zealand, voter registration details are, by law, available to look at but not to copy. Anyone can walk in to a public library anonymously and rifle through the book but the book is chained to the desk and you're not allowed to photocopy it or take photos. Also, it's only present in the local libraries near where the voters live.
