"Given pretty positive leads offshore it's a little bit disappointing - the market was almost flat. Maybe investors are just sitting back, waiting to see what happens when reporting season really gets into the swing of things," said James Smalley, director at Hamilton Hindin Greene.
Chorus led the drop, down 3.6 per cent to $4.215. Communications Minister Simon Bridges today unveiled plans to deregulate the company's copper network where it competes with fibre from 2020. Chorus general counsel Vanessa Oakley said the changes created "some additional complexity for regulatory implementation, such as cost allocation" and raised "questions around incentives to invest in the high-cost rural areas currently served by copper".
