Common technology like cars and home appliances will be connected to the mobile network by 2020, Vodafone predicts.
The mobile provider said yesterday it estimates 20 million devices will be hooked into its New Zealand network by the end of the decade.
This figure is backed up by forecasts from Cisco, which claims there will be more than 15 million internet-capable devices in the country by 2015 - three for every New Zealander.
Vodafone's head of networks Tony Baird said a whole range of machinery would be connected to the web.
"I can imagine a day where all the cars and trucks across the country will be connected up so if your [vehicle] gets stolen they can track its movements and locate it. All of your engine monitoring will be done through [the mobile network]," Baird said.
