Police have now charged a man with the murder of a Tokaanu man who was assaulted in his house near Turangi on 14 April.
Gordon Tunnicliffe, 64, died in a hospice two weeks afterwards.
The accused has not been named. He was originally charged with assault but police have upgraded the charge to murder after analysis of the post-mortem results.
He will appear in the Taupo District Court on Tuesday.
