Drivers are allowed to use hands-free mobile phones, provided they are completely voice-activated, unless they are securely mounted, in which case the driver can operate them infrequently and briefly.
Drivers who do not have hands-free phones have to pull over to make, receive or end calls and texting is banned under all circumstances while driving.
During the blitz, which finishes on Sunday December 2, police will also be checking to make sure that all vehicle occupants are wearing seat belts.
Mr Hodson said Northland has one of the lowest compliance rates when it comes to belting up.
"Northland's road toll currently stands at 14, double the number of deaths our roads last year and we don't want to see any more people die or get seriously injured."
