UPDATED 8.10am The World Anti-Doping Agency has issued a damning report on state-controlled doping in Russian sport.

LISTEN ABOVE: Andy Brown from the Sports Integrity Initiative speaks to Andrew Dickens

It says Russian athletes at both summer and winter Olympics have benefited over at least a four-year period, across all sports, not just athletics.

It's found the sports ministry and secret service "directed and oversaw" the manipulation of urine samples, and resulted in at least 312 falsified results up until at least last year's world swimming championships.

The WADA report says the state-sponsored cheating happened after an "abysmal" medal count at the Vancouver Winter Olympics in 2010.

The investigation undertaken by Canadian lawyer Professor Richard McLaren has found drug cheating by Russian athletes occurred at the London Olympics right up to the Sochi Winter games in 2014.

Sky's Tom Parmenter said clean urine was taken from athletes before the games and frozen in Moscow and then transported to Sochi.

"They created a shadow laboratory in an adjacent room with, bizarrely, a small hole in the wall where samples were passed through and then switched, with the help of intelligence officers working on behalf of the Russian government.

"WADA have, within the last few minutes, come out and said they believe that the entire Russian squad should be prevented from travelling to Rio."

The Sports Integrity Initiative says it should be the final nail in the coffin for Russia's participation at the Rio Olympics.

But spokesman Andy Brown is also pointing the finger at WADA.

He told Andrew Dickens it was already known some of this was going on.

"The idea that 8000 samples were destroyed not 1400, and the idea that WADA told the Russian laboratory they would be coming to pay a surprise visit and investigate them, also makes WADA culpable."

Drug Free Sport NZ chief executive Graeme Steel told Larry Williams a ban must be imposed on Russian participation in the Rio Games, and decisive action must be taken on the findings of the report.

"I don't think there can be any other appropriate response. There may be some athletes that are innocent in all this but it's so pervasive, according to this report, throughout Russian sport that I don't think there's any other appropriate."

Mr Steel said it betrays everything sport stands for, and is a terrible indictment on Russia, but it isn't just the doping that shocks him.

"What shocked me in a way was that McLaren could get access to the material that corroborated the story. What was revealed was what we had heard but the fact they were able to prove it beyond reasonable doubt is perhaps the extraordinary thing."

New Zealand's Olympic Committee says the findings are shocking and deeply concerning and will have an unprecedented impact on international sport.

Mr Brown agrees the ripples could spread to other sports.

He said the Russian Minister of Sport is a member of the FIFA Council and also leading Russia's World cup in 2018.

"And he's been shown to have covered up a positive test for a footballer who plays in the Russian premier league. I imagine he's one of the officials that they've said has got to go. If he does have to go that's going to seriously effect and destabilise the world cup."

The Associated Press has reported Vladimir Putin as saying that Russian officials named as directly responsible in the report, will be suspended.

The NZOC is expecting to hear an initial position from the International Olympic Committee about any sanctions within 24 hours.

At the moment, the IOC is promising "the toughest sanctions available" after the report on Russia's doping practices.

But it doesn't spell out whether it will heed the growing calls for Olympic bans already imposed on Russia's track and field athletes and weightlifters, to be extended to all its competitors in Rio.
