Four months on from its release, John Daniell and Guyon Espiner return with a special episode of The Service revealing their continuing investigations into New Zealand's spy agencies and its Five Eyes partners.

The pair discuss the break-ins to the Indian High Commission and Iranian Embassy, both in Wellington, and we hear what both countries are doing about news of the spy missions against them.

A spokesman for the Indian High Commission says the matter has been raised with New Zealand's Ministry of Foreign Affairs, while a spokesman for the Iranian Embassy responded in writing, quoting the Vienna Conventions, which say embassies are "inviolable" and the "receiving State is under a special duty" to protect such premises. He says New Zealand and Iran have had "brilliant relations" over 50 years and the break-in seems "unrealistic".

As Guyon says in the podcast, however, "Sorry Iran, but it happened".

The Iran spokesman continues, "given that the content of the report has not been confirmed by the New Zealand Government officials, investigating the evidence and signs of the alleged action is in progress. In case of obtaining any confirmed evidence, the necessary legal action will be taken".

Guyon also reveals SIS surveillance of one of New Zealand's most famous poets and war heroes, plus how the Russian infiltrated the New Zealand embassy in Moscow. And we hear details of a darker SIS secret - when the Service discovered a serious crime taking place and didn't report it to police.

Ongoing investigations have uncovered other break-ins by New Zealand's SIS to bug and steal from embassies in Wellington.

It turns out New Zealand's Cold War enemies were not the only targets of New Zealand's SIS. And our series of raids on foreign embassies here in New Zealand was not limited to the 1980s.

In this bonus mini-episode, Guyon and John take the story on from the Cold War era and into the early 1990s. Sources who we can't name because they do not have official permission to speak and may be in danger from identification, have confirmed the SIS broke into the Indian High Commission for MI6 and the Iranian Embassy for the CIA to photograph code books, plant bugs and steal communications in the late 1980s and early 1990s.

In a statement, the SIS said it was "unable to respond to questions about what may or not be specific operational matters".

In the final episode, we close in on the details around the joint MI6/SIS operation targeting the Czechoslovakian Embassy. Finally, someone who was on the raid breaks their silence. But there's a twist...

Wadestown, Wellington: 1986. A group of MI6 and SIS intelligence officers break into the Czechoslovakian Embassy to steal codes used by Warsaw Pact countries to share secret messages. It's the height of the Cold War and knowing what the enemy was up to could, it was argued, save the world from nuclear war. But breaking into an embassy also put New Zealand outside international law, in breach of the Vienna Conventions.

Over five episodes, John Daniell and Guyon Espiner have investigated the politics, spycraft and alliances that led up to one of New Zealand's biggest missions of the Cold War. As Gerald Hensley, the Co-ordinator of Domestic and External Security 1987-89, says, being able to decipher the enemies codes was "the dream". They've also told the story of John's family and the work they did for the SIS, known as The Service.

Now, in Episode 5, we tell the story of the raid itself and what happened that night in 1986.

We also talk about how the codes work and the people whose job it is to crack them, and ask why the Czechoslovakians were targeted and who approved the mission. Czech investigative reporter Robert Brestan tracks down archives in Prague and speaks to diplomats and officials about what they know of the raid.

Then we talk to the man who led the mission for the NZSIS... and hear his surprising version of events.

The Five Eyes is an intelligence alliance with roots that go all the way back to World War II. It's a tight club - but just what does membership demand of us?

To see more images and details about the series, vist the website here.

As the Iron Curtain came down across Europe at the end of World War II and allies united against Nazism splintered into Capitalist and Communist camps, a fraternity of intelligence agencies was created, known as Five Eyes. It was a tight-knit club and one that demanded cooperation and loyalty.

The Five Eyes alliance was a group of countries whose leaders traditionally were, as former GCSB boss Sir Bruce Ferguson put it, White Anglo Saxon Protestants (WASPs). They shared a common world view. It began with a treaty between the United States and Britain, who were then joined by Canada, Australian and, in 1956, New Zealand.

Former Prime Minister and Attorney-General, Sir Geoffrey Palmer, says membership comes with obligations.

"There is a sort of feeling that we have to earn our stripes, if you know what I mean. And so there's that kind of pressure to be super cooperative".

Ferguson disagrees, but admits the relationship is "intimate".

In Episode 4, Paul Buchanan, a former security analyst at US intelligence agencies and the New Zealand-based founder of 36th Parallel Assessments, says those shared bonds have been impervious to political disputes, such as the stoush over New Zealand's nuclear-free policy. Former Prime Minister Helen Clark argues membership is a net positive, but is concerned we are once again getting too close to these traditional allies.

We look at how Russia's efforts in New Zealand in the 1980s compare to their attempt to influence American elections in recent years, the Five Eyes' attempt to influence governments around the world and learn about Sir Bruce's golf games with the CIA and FBI. And we get closer to the details of that raid on the Czechoslovakian embassy.

In the mid-1980s, New Zealand's anti-nuclear policy is attracting international attention. With the ANZUS alliance in crisis, the KGB see an opportunity.

The world lived under the shadow of the nuclear bomb through the 1980s and New Zealand briefly took centre stage in the debate when it went nuclear-free in 1986. It angered the Americans and put pressure on the Five Eyes intelligence network. Soviet Russia saw an opportunity and, according to then-deputy prime minister Geoffrey Palmer, became "extremely active" in New Zealand.

After a year of investigation, Guyon Espiner and John Daniell reveal more stories of what the NZSIS and its enemies got up to during the Cold War.

In Episode 3, Palmer and reveals new details of Russia's "full court press" in this country, and former SIS officer Kit Bennetts explains the "frog kissing" they were doing at the time. Former Soviet diplomat Rouben Azizian gives Moscow's thinking, we delve into the stories of KGB colonel and defector Oleg Gordievsky and Wellington-based spy Sergei Budnik, and reveal what the SIS were doing to former Labour MP Richard Northey.

New Zealand has Cold War spy stories we know about - and some we don't. Even now, it's hard to get people to talk. The big question is: who do you trust?

To see more images and details about the series, vist the website here.

Throughout the Cold War a front-line of sorts stretched around the world, with intelligence officers in the trenches. It reached even to New Zealand, as the two nuclear superpowers squared off over political ideology and power.

Since 1956 New Zealand has been part of the Five Eyes intelligence network, spying on friend and foe alike alongside the United States, Britain, Canada and Australia. The raid on the Czechoslovakian embassy revealed in this podcast was just one operation amongst a world of intrigue. A wilderness of mirrors, where spies fought over information and influence.

In Episode 2 we tell the stories of top New Zealand civil servant and alleged Russian agent Bill Sutch, the expulsion of USSR ambassador Vsevolod Sofinsky, and, from Australia, the Skripov Affair. We hear how the Soviets used "useful idiots" and John's mum chases a target across Wellington.

On his 10th birthday, John Daniell's Mum tells him she used to work for the SIS. But that's just the start of the secrets...

John Daniell grew up in a house where spying was the family business. His mum had worked for New Zealand's Security Intelligence (SIS) before he was born and his step-dad worked for them throughout his childhood.

Through the tense years of the Cold War, John's step-dad, who we're calling Jim Stewart, went out on missions and the family kept New Zealand's secrets. The SIS - known as The Service - works on a need to know basis. But one night, not long before he died, Jim told John a story about one particular mission; a raid on a foreign embassy right here in New Zealand that has remained a closely guarded secret. Until now.
