In its release, the Internet Party said local media had reported the Moment of Truth as a flop despite "record" attendance and revelations made by Edward Snowden.
"This revisionist history has a use-by date that is set to expire in 2017. Further information will continue to come to light about the extent to which New Zealand and the world have been actively deceived by their politicians and the state."
The release also raised the murder of former Democratic National Committee employee Seth Rich. Washington police have repeatedly said they think Rich was shot in a random robbery attempt.
Dotcom is a leading promoter of the conspiracy theory that Rich had supplied DNC documents to WikiLeaks and was killed as a result.
Rich's family has accused Dotcom of attempting to hack Rich's email account, a claim he denies.
The Internet Party release said both it and Dotcom are long-term supporters of WikiLeaks "and we are certain such claims would not be made unless they were true".
