However, some commenting thought the criticism was unfair.
"I remember getting my tail light fixed and literally by the afternoon it had blown again. They probably didn't know," wrote Angelique Lamb.
Rotorua Senior Sergeant Steven Shaw confirmed the driver probably did not realise, as the car was part of a fleet used 24 hours a day by many different drivers.
"Now that it's been brought to our attention we'll fix it, it's as simple as that."
He said he would prefer if people alerted police to incidents like this rather than post to social media, "just like we tell members of the public", he said.
"At the end of the day we deal with these things all day every day."
Acting Sergeant for road safety Chris McLeod said police gave members of the public a chance to fix safety hazards like broken tail lights before they issued a ticket, so similarly there was no need to discipline the officer driving the car at the time the photo was taken.
"It's all about road safety. It's not about fining people, and certainly not for minor road safety incidents like this."
He said the car in question was currently at the Rotorua police station's preferred mechanic getting fixed.
