International mobile infrastructure measuring company Tutela says Vodafone has New Zealand’s fastest mobile data. The company beats its rivals at both downloads and uploads.

Elsewhere 2degrees has the highest consistent quality and the best latency.

Tutela describes its methodology as “crowdsourced data”. It has a panel of 300 million phone users worldwide. In New Zealand it took 3.89 billion network quality measurements including 1.36 million speed tests.

Testing took place between March and May of this year. As New Zealand was in lockdown for much of this time the numbers may not reflect everyday mobile performance. The tests only took place in areas where all three carriers operate.

When it comes to raw mobile speed Vodafone is well in front of Spark and 2degrees. Its median download speed is 23.9 Mbps. Uploads come in at 9.2 Mbps.

Spark trails with a median download speed of 20 Mbps. That’s not far behind Vodafone, yet it has the slowest upload speed at 7.7 Mbps.

While 2degrees has the slowest median download speed at 19.5 Mbps, that is only 4.4 Mbps behind the leader. The company is second when it comes to upload speeds with a median of 8.1 Mbps.

Tutela says the 2degrees network is good enough for applications like high definition video calls, streaming video and mobile gaming for 85.6 percent of the time. It calls this measure “consistent quality”.

Spark follows a fraction behind meeting the standard for 84.9 percent of the time.

Vodafone brings up the rear on that measure, reaching the required level 81.9 percent of the time.

2degrees had the best one-way latency result at 24.5 ms. It was followed by Vodafone at 25.9 ms. Spark in third for a median one-way latency of 29.4 ms.
