Lionel Terry (not his real name but I'll let him give that if he wants) did a lot of bolting up at Kiera a few years ago. He did some necessary rebolting, did some questionable retrobolting and sunk bolts into some new routes. The manner in which he went about this rubbed up a lot of the local climbers the wrong way.
There was a bit of talk (on here and on a now defunct and inaccessible Facebook forum) about doing a lot of chopping. The only chopping that actually got done was one route which was directly above the walking track. You can read the trip report and discussion here.
If you wanted to debolt more then feel free. Nobody is going to be unhappy if you get rid of any of the new bolts...especially any of the more pointless/redundant ones.
