The head of the Southern Cross Cable Network has disputed Prime Minister John Key's claim that a cable had been tapped into as part of a proposition to collect metadata.

Prime Minister John Key has challenged Edward Snowden and Glenn Greenwald to front up with evidence of their claims of mass surveillance and NSA bases in New Zealand.

Laila Harre says she has no doubt Kim Dotcom is telling the truth over an email dismissed as fake, which the Internet Party founder says is "100 per cent true".

'You are being watched,' said renegade former intelligence analyst Edward Snowden, as he went on to claim the NSA has two facilities in NZ - one of them in Auckland.

My phone rang on Sunday night. No caller ID. But I'm curious. "Hello Mark, this is Kim Dotcom."

John Key says he won't release documents that show that spy agencies do not conduct mass surveillance until after Glenn Greenwald tries to prove the claim.

Prime Minister dismisses claims GCSB was involved in mass surveillance of New Zealanders and attacks the Pulitzer-winning journalist who made them.

The relationship between the Government and "the sordid workings of Hollywood" will form a key part of Kim Dotcom's highly anticipated announcement on Monday.

New Zealanders remain sceptical about whether Kim Dotcom's pre-election bombshell will prove Prime Minister John Key hasn't told the truth, a Herald- DigiPoll survey shows.

Internet-Mana press secretary Pam Corkery offered to resign after swearing at journalists at the party's launch, but she says she won't apologise to the reporters.

The new-found wealth of entrepreneur Kim Dotcom came in part from an immigrant who has had at least $15m in assets seized in a money-laundering inquiry.

Mega's chief executive doesn't think the seizure of 20 per cent of the company's shares will cause problems for its backdoor listing on the New Zealand stock exchange.

Kim Dotcom says he's not behind the hacking of the Whale Oil blog, and he's not paid out any of a $5m bounty he'd offered for information to help his legal case.

To borrow Churchill's famous line, Kim Dotcom is a riddle wrapped in a mystery inside an enigma.

Blogger Cameron Slater says he will complain to police about the hacking of his Whale Oil website and will name entrepreneur Kim Dotcom as someone detectives should speak to.

In the lead-up to the election, the Herald is delivering political leaders as they're meant to be seen. Under the grill.

Hone Harawira sees the Internet Mana alliance enduring beyond the election because he and Laila Harre are synchronizing so well.

The man described as Winston Peter’s "right hand man” has quit NZ First and is now working for the Internet Mana alliance.

There is no question which party has made the most impact in the "phony war" of these weeks before the election campaign gets properly under way.

They live a life of unimaginable luxury — yachts worth hundreds of millions, the best food, international shopping — and that’s just the staff.

Invercargill Mayor Tim Shadbolt must be wondering whether New Zealand society has changed at all in 50 years.

'Are you Red-dee for a Rev-Oh - Loo- Shin? Are you Red-dee to take down the Government? Are you Red-dee to extradite John Key?"

Prime Minister John Key will face both Internet-Mana Party leaders on Monday at his only local public debate in his Helensville electorate.

The icing on the cake for Mr Dotcom is that the stand-off will occur in his home electorate of Helensville.
