On December 18, Kempson made a final attempt to keep his name a secret by appealing to the Supreme Court but that last-minute bid was rejected on Tuesday and name suppression lapsed on all matters on Tuesday.
While Kempson's identity has previously been revealed by overseas media, and Google in an email to subscribers, this is the first time he has been publicly named in New Zealand.
The family said the suppression of Kempson's name had allowed people to remember Grace - “a young, vibrant girl who set out to see the world, instead of the man who took her life".
