[1][2][3] After lengthy internal and corporate trials, a Vodafone New Zealand and Telecom dispute about network interference pushed the date to 29 May.
With the launch of the XT network, a number of new services were available to subscribers, including Prepaid roaming, video calls, Mobile TV, and high-speed internet access.
However, Telecom had said it is working with Vodafone to resolve the issues and was surprised by that company's decision to pursue legal action.

Telecom said a technical fault, affecting a Christchurch-based technology component that was installed to fix a prior fault, had caused the loss of mobile service, including voice, SMS, and mobile broadband[6][7] At approximately 7:00 am on the morning of the network outage, Telecom published a statement via Twitter acknowledging the issues.
On Wednesday, 27 January 2010 around mid-morning, the Telecom XT Mobile Network once again suffered a major outage, affecting approximately 100,000 customers south of Taupō.
Advertising material at the time proclaimed the network to reach "97% of places Kiwis live and work".
[10] As of 2011 the meaning of "XT" remains unknown to the public, as even Telecom's website fails to address this anomaly.
"The 4G LTE coverage was initially offered to subscribers in Auckland, Wellington and Christchurch starting 12 November 2013.
