Chorus’ network hit its 2017 peak at 9.25pm on December 10. The broadband network was delivering 1.328 Terabits per second.

Less than four weeks later it hit a new high. On January 4, at the same hour, the network was spitting out 1.33 Terabits per second. No doubt the record will soon broken again as numbers continue to climb.

Porirua people are New Zealand's most voracious data consumers. In December, the average Porirua household chewed through 202GB, that’s 34 percent up on a year earlier.

Nationwide average data consumption on the Chorus network climbed a similar amount. It is now 174GB a month. That’s up from 123GB a year ago.

Users with fibre accounts use more data than those with a copper connection. While the average monthly data base across the entire Chorus network is 174GB, customers with fibre use around 250GB.

In September a Chorus forecast said this will climb to an average of around 680GB a month by 2020. In part the rise will come as more accounts move from copper to fibre.

The growth is largely about television moving from broadcast distribution to online, on-demand delivery.

Chorus network strategy manager Kurt Rodgers says it is not just the big international providers like Netflix driving this change. He says TVNZ and Three launched live streaming in 2017 and that has helped online television become mainstream.

Rodgers says people are watching on smart TVs, but they also watch on phones and tablets connected to home wi-fi networks. He says phone handsets are used more often with wi-fi than as traditional phones.

Broadband speeds on the Chorus network are also higher. Dunedin, which was the original Gigatown now has an average connection speed of 265Mbps. Rotorua is next on 72Mbps and Wellington is in third sport with 70Mbps. The national average across the Chorus network is 64Mbps.
