The disturbing facts of the case were not news to the Aims, who had been kept informed by police.
"It is beyond what good human beings can accept that anyone could do such an act. For that first week it was like being in a film on television that you couldn't change channels. It was like that today - it doesn't seem real."
Mr Aim said he believed the guilty plea, immediately before a trial was due to begin, was "unusual" but it had spared his family the ordeal of a trial.
His daughter's death had not changed his views on New Zealand. He first came with his grandfather 34 years ago and then visited with Peggy 14 years ago for his cousin's wedding.
"I have nothing but praise for New Zealand, it's a beautiful country. The people are friendly and terrible acts of violence happen all over the world."
He said the family had visited Taupo and laid flowers at the murder scene.
