Actually Vodafone dominate Auckland and Wellington is a mixed bag with average mobile data, and a range of fixed line suppliers mainly Telstra taking market share.

Mobile termination is heavily regulated, and killed telecom of late as it let in 2 degrees and abolished all of Telecom's prepay EBITDA.

As a result of LLU and regulation in general the only winners with Telco's these days are consumers. We demand newer and better products ($billions of capex) and don't want to pay much for it (less EBITDA) and don't want to be contracted (no switching costs).
