The committee had identified "a number of instances where it appears that Diligent was not, or may have have been, in compliance with its New Zealand regulatory obligations".
"For example, a number of smaller option grants to employees in New Zealand were made in the absence of a prospectus, which would create issues under New Zealand law if a prospectus was required," the company said.
Diligent said the committee deemed any non-compliance was "inadvertent" and could be partly blamed on constrained resources and complex regulations in multiple countries.
Any issues discovered would be reported fully to the NZX and the Financial Markets Authority, Diligent said.
Diligent's share price closed down 10c yesterday at $5.45.
In its latest quarterly result released this week, Diligent said revenue for the three months to December 31 was US$13.6 million, up 109 per cent from the same period in 2011. Revenue for the whole of 2012 was US$ 43.7 million, up 143 per cent from 2011.
