New Zealanders have already used 53% more internet data than last year.

That's 53,000 terabytes, excluding data from mobile phone connections.

It's the equivalent of streaming more than 12 million high definition movies.

Almost half of all broadband connections have data caps of 50 gigabytes or more.

Three years ago, only 4% had data caps that large.

Copper connections still dominate the broadband market, but fibre has jumped to 46,000 connections – three times what it was last year.

Mobile phone internet connections are up 16% to 3.7 million.
