Spark New Zealand, the rebranded Telecom Corp, said it was nearing the end of the first phase of its transformation from a traditional telco to a digital services business. Managing director Simon Moutter told shareholders at the annual meeting in Auckland today said they had done the hard work of restructuring the business from one that relied on dwindling landline use to one that incorporated a landline and mobile phone network, cloud-based business services, big data and a subscription internet service.
