Whanganui police will use unmarked cars and plain-clothes police staff in a crackdown this month on drivers using mobile phones.
Sergeant Colin Wright said drivers caught could expect an infringement notice of $80 and 20 demerit points. If a driver accrued more than 100 demerit points in two years they would have their driver's licence suspended for three months.
Figures from NZTA and NZ Police show that in 2018 crashes because of distracted driving resulted in 12 deaths and 155 injuries.
Wright said the main distraction while driving was using a mobile phone to call, text or take photographs.
