The NZX is under questioning from the Financial Markets Authority about not disclosing information on time, a failure that could constitute a breach of their own rules.
NZX comments about the performance of Clear Grain Exchange, which it purchased in 2009, began negatively when chief executive Mark Weldon reportedly talked about the poor performance of the grain exchange in May last year.
However, according to Radio New Zealand, the latest annual report from NZX said that trading momentum in the grain exchange had gathered pace.
The contrasting comments have led the Financial Markets Authority to start asking questions.
The $6.4 million purchase of Clear Grain Exchange is under further strain, with NZX taking legal action against the former owners, claiming a breach of warranty.
Shares in NZX fell 5 cents on Friday to $2.30.
Failing to disclose information in a timely manner is something the industry frowns on, as it could give investors a false impression.
