Cairns' defence team will say Vincent is lying.
Brendon McCullum
The Black Caps skipper is expected to give formal evidence next week. He played for the Kolkata Knight Riders in the IPL during 2008.
Cairns was his idol and the pair became friends. McCullum will allege they once met in a hotel room in India and Cairns steered the conversation towards "spread betting". Cairns is alleged to have said "everyone was doing it" and he didn't want McCullum to miss out, with payments of $70,000 to $180,000 per game. McCullum was shocked by the alleged proposal and later declined to be involved.
They met again later at a café in Worcester in June 2008, when Cairns allegedly asked McCullum if he had changed his mind. He had not.
McCullum did not officially report the alleged approach - something he regrets - until 2011 following an anti-corruption presentation ahead of the World Cup.
Cairns' defence team will say McCullum is lying.
Andre Adams
Close friends with Vincent, who approached him to fix games in the middle of 2008. Adams declined but did not report his friend because of his fragile mental health. Will allege that Cairns spoke freely about match-fixing at a dinner attended by members of the New Zealand team and boasted that no one could ever prove it.
Chris Harris
Captained the Hyderabad Heroes in the ICL during 2007 and 2008. Remembers two specific games involving the Chandigarh Lions and other teams in the competition.
The first involved Cairns hitting the ball for a simple catch, which was dropped by the other team, before he went for a "silly run" and was run out. Harris found this suspicious.
In the second game, both teams seemed to deliberately underperform until the Chandigarh wicketkeeper started to score some runs and won the game. The winning captain, Chris Cairns, was not happy, according to Harris.
Shane Bond
Played for the Dehli Giants in the ICL and also remembers the same game as Harris when Cairns was unhappy his team won. Umpires in the ICL are also expected to give evidence about suspicious behaviour. McCullum also told Bond that Cairns had allegedly approached him to fix matches.
Daniel Vettori
Was told by McCullum that Cairns had allegedly approached him to fix matches.
Kyle Mills
Was told by McCullum that Cairns had allegedly approached him to fix matches.
