McCullum comfortable with his evidence in court

New Zealand captain Brendon McCullum has stood by the evidence he gave in the trial of former teammate Chris Cairns, despite the former Kiwi allrounder being found not guilty of perjury in a London court.

Before his team's two-match Test series against Sri Lanka, starting on Thursday, McCullum had to answer a few questions about Cairns, who publicly asked the current Black Caps skipper for an explanation about why he gave evidence against him.

In court, McCullum said Cairns approached him to fix matches in 2008 but admitted that he did not come forward until now because Cairns was his 'hero'.

McCullum told reporters on Wednesday: "From my point of view, I was comfortable with the evidence I gave in London. I stand by that evidence. It was a pretty big deal in New Zealand cricket, and now that it's over, it's time to move on.

"I don't think my reputation has been on the line during the whole thing. I was one of a number of witnesses who gave evidence in the trial.

"People are going to have their own opinions on what unfolded. I was comfortable with it, and I think it's time to move on and focus on cricket.

"I don't think I need to [give Cairns an explanation]."
