Shares in APN News & Media are in a trading halt until Tuesday, as the company investigates questions about the leadership of chief executive Brett Chenoweth by Independent News & Media.
According to a report from Ireland, Independent News & Media, which owns 29% of APN, is calling for Mr Chenoweth's resignation, saying it has lost confidence in him.
In response, APN said it is investigating the comments, but believes they arise from the fact that it is considering a capital raising.
APN said it asked for the trading halt, while it considers the capital raising.
APN owns the New Zealand Herald.
