Chorus' share price is up slightly this afternoon after plummeting for three days.
The company's share price fell 10.5c or 6.89 per cent yesterday on the back of a 35c drop last week.
But shares were trading at $1.48 around 2:30 this afternoon, up 2.78 per cent on yesterday's close.
The slight regain of ground follows Chorus announcing yesterday it would take the Commerce Commission to the High Court over whether the regulator applied the law correctly in making cuts to wholesale broadband prices.
In November, the commission indicated wholesale broadband prices should be cut by 23 per cent. These prices are what Chorus can charge internet retailers such as Vodafone or Orcon for broadband services over the copper-line phone network.
