CIA plane spotted in Wellington

It looks like just another white, anonymous private jet parked in Wellington - the kind that come and go all the time.

But a small five-digit number on the plane's tail gives away a big secret: It's owned by the United States' Central Intelligence Agency, more commonly known as the CIA.

The registration number is 10030, and type that into Google and it reveals the Gulfstream Aerospace G-IV is in the hands of one of the world's most powerful and ruthless spy agencies.

Its very presence in the country confirms the 'VVIP' event in Queenstown is a top-secret meeting of the Five Eyes nations.

Five Eyes is the name of the global spying alliance of the US, the UK, Canada, Australia and New Zealand.

Prime Minister Bill English has confirmed there will be more than one important visitor, but shot down talk it was former US President Barack Obama.

US Vice President Mike Pence is currently on a tour around Asia and Australia, but New Zealand is not on his agenda.

Quit the Five Eyes - Nicky Hagar

Author and investigative journalist Nicky Hager appeared on Three's The Project on Friday night, and asked what we get from the alliance.

"If we don't think that we're exactly likeminded and the same as the United States on their foreign policy and military policy, that's when we have to think again," he says.

Mr Hager says that governments use the fear of terrorism to extend their surveillance powers.

"It's kind of like: 'come on children, be scared of terrorism, and don't question what's going on'," he says.

"Our GCSB - who will say that they study terrorism - have hardly got any staff allocated to terrorism. They've got people spying on the Pacific Islands, in India, and Japan, and Antarctica and all these different part of the world."
