Mills said the organisation would be there to help both Cairns and the other players involved in the trial while New Zealand Cricket have promised to give their full support to McCullum in the wake of the trial.
Cairns had previously won £90,000 in damages from former Indian Premier League boss Lalit Modi in a libel case three years ago but was later accused of lying, paving the way for the second case.
During the trial, McCullum (right) claimed Cairns had twice asked him to fix matches, but the latter was cleared in a case which he described as “five years of hell”.
New Zealand Cricket chairman Stuart Heal said: “Brendon is an employee of ours, so we’ve got a duty of care that makes sure he’s free of harassment and all that humiliation stuff. I hope it doesn’t come to that but of course we’ll support him.”
