Vodafone continues to outperform its rivals in the nationwide broadband market and offers the fastest web-browsing speeds, according to testing service TrueNet.
Since stealing the lead from other internet companies last December, Vodafone has kept the top position in TrueNet tests between January and May.
Telecom came in second and "continues to maintain its consistently quick webpage download time", according to a TrueNet report released yesterday.
TelstraClear's DSL service came in third, despite slowing down between March and May.
However, the results for Slingshot over the first four months of this year were "a little depressing ... with download times being erratic since February".
