Cairns denied he approached McCullum to underperform was found not guilty of charges of perjury and perverting the course of justice last December.
McCullum's evidence was repeatedly attacked by Cairns' legal team during the trial, particularly the three year delay before he reported the alleged approaches from Cairns and the "shifting sands" of his three statements to investigators
"There have been inconsistencies and inaccuracies in Brendon's story from the beginning and not surprisingly this occurs again in his book in a number of respects," said Cairns.
"There are things that Brendon could never have forgotten if his version of events was correct.
"Things which he inexplicably omitted and added to his third statement after the news became public. But he chose to not write and explain about those," said Cairns.
"All of the evidence has been considered to a degree of detail impossible to summarise in the media during both a High Court trial and then a criminal trial. I have been found not guilty.
"I am trying to move on with my life and I suggest Brendon does the same. I hope he finds peace in his retirement, and I hope for his sake, that he never has to go through what I did in mine."
