"Most people were happy to see us and happy with our efforts to keep drink-drivers off the roads. You get the odd one or two who feel inconvenienced or upset but we make no apologies for that because it's about keeping impaired drivers off the road."
Crowe said although there were 36 alleged drink-drivers and that was still too high, police were no longer seeing the high readings like in the past.
"That is a good thing but clearly people still need to make better plans about who is going to drive before heading out to ensure everyone is getting home safely. When you don't make plans, that's when bad decisions happen."
Crowe said he wanted to thank the responsible drivers.
"The number of people processed by police is obviously disappointing because there is a small percentage who are not getting the message but a vast majority of drivers had no alcohol at all on their breath and we applaud that."
Operation Tri-Cities heads to the Western Bay this weekend and all drivers were urged to ensure they made proper plans before heading out to celebrate the end of work and the Christmas holidays, Crowe said.
