Former UnitedNetworks Communications general manager Sean McDonald has left the metro ethernet provider.
His departure follows the purchase of UnitedNetworks last year by Auckland electricity network provider Vector, which has its own metro ethernet business, Tangent.
Maxine Elliott, Vector's general manager for Tangent and UnitedNetworks Communications, says "we're reviewing both businesses to see how we'll pull them together."
UnitedNetworks Communications and Tangent both run on the open network model, selling capacity to content and service providers, who then on-sell to end-users. Both are also the result of electricity companies laying fibre in disused underground infrastructure.
At the time of the sale of UnitedNetworks, the communications division had networks in the Auckland and Wellington CBDs and capacity of up to 10Gbit/s.
A major customer is Hitachi Data Systems, which uses the network to connect clients to its data centre business at speeds sometimes exceeding 1Gbit/s, but most customers use it at 10 or 100Mbit/s.
Elliot was appointed about a month ago and McDonald left a few weeks before that, following some work on the transition.
McDonald has bought into a media communications business part-owned by his brother, where he has taken the role of marketing director.
