Shareholders Association associate director Alan Best told the meeting that Mogridge's performance as Pyne Gould chairman "did not bear close scrutiny".
"He really is in the chair when the state of the accounts today is inadequate," Best said, adding that Mogridge was "closely aligned with the company historically" and could not be considered an independent chairman.
The association said it was "completely unsatisfactory" for Pyne Gould to be holding an annual meeting without a complete set of audited accounts.
"Unless we hear some comprehensive and satisfactory answers to shareholders' questions, NZSA will consider asking for PGC shares to be suspended from trading until audited accounts are produced because, in our view, the market is currently not properly informed," it said.
Mogridge, who was re-elected yesterday, defended his track record, pointing out the key role he played in the firm's $250 million capital reconstruction.
Pyne Gould reported a profit of $18.4 million for the year to June 30, down from $45.2 million a year earlier. Its shares closed down 1c at 46c yesterday.
The issue
• Pyne Gould released its annual report last month without a completed audit from PwC.
• Shareholders complain they are not being properly informed about the firm's financial situation.
