Unless new evidence came out, commenting further would only serve to muddy the waters, Hope said.
He released a final statement on Tuesday explaining why Watson had failed to convince him he was innocent of murdering his daughter Olivia Hope, 17, and her friend Ben Smart, 21.
The pair disappeared in the early hours of New Year's Day 1998 after a party at Furneaux Lodge, in the Marlborough Sounds.
In his statement, Hope described Watson as elusive when asked about his movements that day, claiming the convicted murderer seemed to have rehearsed his answers.
"His response was absolute silence on some of the more circumstantial elements of the prosecution case ... "When confronted with this he was mute, unemotional, disconnected."
Hope said Watson was unable to convince him of his innocence in relation to other parts of their conversation, including his arrival time at Erie Bay, a sighting of Blade at Marine Head, and squabs in Blade that had large sections cut out.
Watson had always said he left Endeavour Inlet early on New Year's Day and sailed to Erie Bay onboard his sloop Blade, arriving sometime around noon.
However, the police and prosecution case argued he did not arrive until around 5pm, after sailing out to Cook Strait to dump the bodies of Olivia and Smart.
White said there was never going to be handshakes at the meeting, which stretched over two three-hour sessions, but there were some moments of connection between the two men.
"You and I are both victims. You believe you're a victim," Hope said at one point.
"I know I'm a victim - I know I'm a victim," Watson replied.
"We're a victim. We never got the truth," Hope said. "We haven't got the truth yet. Most people have got the comfort of the police, the legal system having done their job, so that's why you're in here."
