John Key is going on the offensive as Kim Dotcom prepares to reveal his 'bombshell' revelations about New Zealand's spying practices.
Mr Dotcom is hosting an event this evening where he's expected to reveal evidence the GCSB has allegedly been conducting mass surveillance of Kiwis.
But Mr Key is denying the accusations, saying while spy officials were considering a form of mass surveillance, the plan never got off the ground.
"Dotcom is trying to save Dotcom's butt, and it's a reasonably large one so he's bought in all of these people, three little butts to save his butt, and it won't work but they'll say and do anything and bamoozle people," he told Newstalk ZB.
"You're dealing with a guy who is basically interested in Kim Dotcom, so we've got an election, which is about New Zealanders, being heavily influenced by a guy who cares about himself and not being extradited to the United States."
Tonight's event will be live streamed on onenews.co.nz from 7pm
Mr Dotcom will be joined by Pulitzer prize-winning journalist Glenn Greenwald, who published NSA whistleblower Edward Snowden's evidence of mass surveillance in the US, Wikileaks founder Julian Assange, likely to be via video link, and international human rights lawyer Robert Amsterdam.
Mr Key is dismissing the presentation as a "sound and light show".
However, he won't be drawn on suggestions New Zealand has been spying on China.
There's speculation Mr Greenwald could reveal evidence the GCSB has been collecting intelligence on our largest trading partner.
But Mr Key told Newstalk ZB's Leader's Breakfast it isn't something he's able to confirm or deny.
However, he did say the GCSB hasn't done anything that would undermine the trading relationship.
