Kim Dotcom has failed to deliver on his promise to prove John Key knew about him before Dotcom's 2012 arrest, with an email produced as evidence being labeled a fake.
"My case only affects me. It doesn't matter tonight, that's why we didn't make a big deal out of it," Mr Dotcom, the Internet Party founder, told a news conference after his "Moment of Truth" public meeting last night.
For years now Mr Dotcom has promised proof.
"I know for a fact that John Key knew before January 19," he told TVNZ's Q+A programme in November 2012.
Mr Dotcom even offered a $5 million reward for evidence supporting his theory that Hollywood was calling the shots.
But it wasn't mentioned in The Moment of Truth. Instead, just hours before, a four-year-old email suspiciously surfaced linking John Key and Warner Brothers' chief executive to a plot to trap the alleged internet pirate in New Zealand and then extradite him.
Mr Key said today: "I just know I've never had a conversation of that nature. The studios would know. They've looked at their records. They say it's fake."
So does computer forensic scientist Daniel Ayers.
"This email did not come out of an email programme. In my view it has to have been created by hand, faked by hand," he said.
Questions about the email evidence did not go down well with Kim Dotcom.
"You need to wake up and do your jobs," he told journalists last night. "You have failed New Zealanders in the past."
Internet Party leader Laila Harre is standing by Mr Dotcom on the email.
"What I say is that Kim believes in the authenticity of the email. I trust Kim's judgment."
Despite calling US journalist Glenn Greenwald "a loser" and a "henchman", Mr Key has been surprisingly reserved when it comes to Kim Dotcom's failure to deliver.
When asked would he say Mr Dotcom was a liar, Mr Key said: "In the end I don't care about the guy anymore. What I care about is the fact that we are three or four days from an election."
And, ONE News deputy political editor Michael Parkin says, time's running out for Kim Dotcom to prove his case.
