UPDATED 7.10am: Lou Vincent has revealed allegation after allegation as he's testified at the trial of Chris Cairns.

LISTEN ABOVE: NZME reporter Jared Savage joins Rachel Smalled on the KPMG Early Edition to discuss developments in the Chris Cairns trial.

 The former Black Cap is the first witness in Cairns' perjury trial in London.

 NZME. reporter Jared Savage said Vincent admitted to the court that he was involved in match fixing in the Indian Cricket League in 2008.

 He outlined what he said were Cairns' instructions, including that he was to score 10 to 15 runs off 20 balls.

 Jared Savage said Vincent laid allegation after allegation all day, for about five hours.

 Lou Vincent claims he was offered a woman as a present and a wad of cash to provide information to a bookie when he was playing in the ICL cricket league.

 Savage reports the former Black Cap confessed to match fixing, saying it was all at the instruction of Cairns.

 He went on to claim Cairns was angry when Vincent mistakenly scored 28 runs in one match, telling him Vincent had cost him millions.

 The former Black Cap has been the first witness called in Cairns' perjury trial in London.

 Vincent has told Southwark Crown Court he worked under direct orders from Chris Cairns to match fix in the Indian Cricket League in 2008.

 He's also named former teammate Daryl Tuffey as another person who was fixing.

 Cairns is charged with perjury in relation to a 2012 libel trial in which he stated he had "never, ever cheated at cricket".

 He, along with friend and barrister Andrew Fitch-Holland, also face a charge of perverting the course of justice for allegedly trying to induce Vincent to give a false statement.

 Vincent arrived at the court with his wife Suzie Markham saying "first into bat, hopefully it's a green one", referring to the fact that he's the first witness in a month-long trial.

 At least seven New Zealand cricketers are expected to give evidence against their former team mate in his trial on charges of perjury and perverting the course of Justice.
