Wairarapa police ran several checkpoints every day during the two-week crackdown, and used covert techniques to nab drivers breaking the rules, Mr Crawley said.
People needed to realise that talking on the phone, or using other devices, posed a serious risk to other road users, he said.
"You've got a responsibility to yourself and other people to make sure you are paying attention to what you are doing."
