Overall the cities all showed growth of over 50 per cent over the last 12 months, with Rotorua's connection speed jumping 84.6 per cent from 28.6Mbps to 52.8Mbps.
"The results show that New Zealanders are downloading, streaming TV and gaming at a huge rate," says Chorus network strategy manager Kurt Rodgers.
"Our use of new technology is also driving the increase in speed. It doesn't matter whether you live in the cities or live rurally, content is flying into our homes faster due to newer technology such as high definition online television and more interactive and complex online games."
"As a nation our average data use is growing fast. Last year we chewed through 1.5 exabytes (or 1,500,000,000 gigabytes) of data. That's a lot of information, emails, movies, music, and more being bundled and carried all over the country," Rodgers said.
