Kordia has sold its retail broadband arm, Orcon, for an undisclosed sum.
The state-owned telecommunications and media company says the business has been bought by a group of New Zealand business people, headed by Vivid Networks' managing director, Warren Hurst.
The company paid $24.3 million for Orcon in 2007.
Kordia Group chairman David Clarke says the company wants to concentrate on its core networks business and also has a significant amount of technology.
He says Kordia has growth and traction in those markets and believes it has a competitive advantage.
Mr Clarke says Kordia Group has realised retail is not its core business because it requires huge marketing spend and different skill sets.
