New cyber monitoring measures are being put to Parliament with the backing of Police Minister Judith Collins, which would give police and the SIS power to monitor all aspects of online life.
The Interception Capability Act allows officials to tap into texts, email, internet surfing, social networking and chatting, to catch criminals using new technologies to communicate.
Technicians have already begun installing specialist spying devices and software into telephone exchanges and internet companies, providing police with the capability to monitor almost all communications.
A police spokesperson says officials will still have to obtain an interception warrant, but this will cover all internet and phone usage.
