Shares in industrial resins and specialties group Nuplex Industries were down 3.2 percent in early trading, following yesterday's announcement the Securities Commission is filing civil proceedings against the company and six current and former directors.
The commission alleges Nuplex breached its continuous disclosure obligations under the NZX Listing Rules and the Securities Markets Act by failing to disclose to the market a breach of a banking covenant.
Nuplex denied the allegations and said the company and its directors would defend themselves vigorously.
Shares in Nuplex fell as much as 12c in early trading, but the decline eased to 10c within a few minutes of the market opening, with the stock price down to 2.9 percent to 337.
