Such crashes and deaths were preventable, Mr Campion said.
"Enough is enough. People need to focus on what they are doing and drive far more safely.
"It's not acceptable to have this many deaths on Western Bay roads, nor is acceptable to have so many serious-injury crashes. If you go back over 15 years, we had a reputation for being the least safest place to drive in the country and we are starting to get back to having that mantle again. It's got to stop."
Mr Campion said speed and distractions were two major factors in road crashes. Distractions came in many forms, and included drivers using mobile phones, and drinking or eating food, he said.
He urged drivers to take extreme care, reduce their speed, drive to the conditions, watch following distances, and concentrate solely on their driving. "My question to all motorists is: Who is going to be next to receive a knock on the door from police at 2am in the morning?
"Tauranga is a fantastic place to live - let's make sure our roads are also the safest places to drive."
