The Commission announced the imrovement on Tuesday following a collaboration between its independent testing partner, SamKnows, and the industry, to identify and fix performance issues with premium fibre plans.

“Overall performance is now in line with advertised speeds. There is no noticeable dip in performance during peak hours and performance differences across the country have been smoothed,” says Telecommunications Commissioner Tristan Gilbertson.

The report shows the average download speed of Fibre Max plans has increased by more than 200 Mbps, or 35%, since the previous report, to around 840 Mbps.

“We’re pleased that for the first time the programme can now also compare Fibre Max plan results by provider, as well as the performance of Vodafone’s cable technology,” says Gilbertson.

The results show that average download speeds are similar across the tested providers’ Fibre Max plans.

Meanwhile, the Commission said Vodafone’s cable (Ultrafast HFC Max plan) is delivering speeds significantly higher than copper technologies but around 160 Mbps slower than premium fibre plans.

The Commission notes that as illustrated in previous reports, fixed wireless technology (broadband delivered via the 4G mobile network) continues to experience significant latency.

“While 4G fixed wireless can offer higher download speeds than copper broadband, it is not comparable to fibre in its performance in real-time applications. Higher latency can have a real impact on consumers who use the internet for video calling, online gaming and watching high-definition video,” Gilbertson said.

The report also shows an improvement in Netflix streaming results for copper broadband and fixed wireless technologies, attributable to Netflix changing the way it delivers ultra-high definition and 4K video.

In August last year - as reported by iTWire - The Commerce Commission's Measuring Broadband New Zealand report revealed that there has been a 10% drop in the peak time broadband speeds of high-speed Fibre Max in New Zealand.
