New Zealand Cricket have released a statement this afternoon to express their dismay that Brendon McCullum's testimony to the International Cricket Council has been leaked to the media.
"We can confirm that Brendon is not under investigation by the ICC and his testimony has actually been applauded by them," the statement read.
"NZC has 100 per cent confidence in our captain and his role in tackling corruption."
Details of the match-fixing offer made to, and rebuffed by, the New Zealand captain have been leaked to media.
The approach, first reported by the Herald on Friday, is part of the ICC's investigation into match-fixing.
