Orcon, Telecom and Xnet are offering customers consistent broadband performance across the country, while TelstraClear users in Auckland get a better run than those in other parts of New Zealand, according to testing service TrueNet.
In its latest report, TrueNet examined internet companies' performance in Auckland and compared it with performances in the rest of New Zealand.
The tests, done during December, found that Telecom, Orcon and Xnet had a consistent performance across the country.
TrueNet measured "performance" by comparing the speeds during heavy periods of internet use (in the evening) as a percentage of those offered at off-peak times.
Telecom, Orcon and Xnet's speeds during peak periods were above 95 per cent of their speeds during periods of low demand in both Auckland and other parts of the country.
