Chorus is having to amend a key document spelling out access to its copper business after the Communications and Information Technology Minister declined to approve it.
The access deed of undertaking sets out the requirements for access to Chorus's fixed line copper network which it expects to inherit as part of Telecom's split.
The minister, Steven Joyce, says the deed did not meet the requirements of the Telecommunications Act and he has written to Telecom setting out his reasons for declining it.
Mr Joyce says he's asked for clarification about how input standards apply, for Chorus to improve transparency in relation to disclosure of information to the Commerce Commission and how the contract between Crown Fibre Holdings and Chorus will interact with the deed.
Chorus will submit an amended version of the deed by 21 October.
