Would be interesting to know what the letter drop said exactly. Wonder if it's case of the letter simply saying fibre was being laid (which is true to be fair to Chorus) and people interpolating from it to assume it was UFB rather than another form of fibre (which again is fair enough assumption for layman to make given all the recent media attention on UFB and Chorus significant involvement with it). But then again easy enough for someone to bring up the wrong mail merge template by accident. It's disappointing yeah but by all accounts it was a long shot to expect UFB to be rolled out.
