Police paid $10,000 for a social media audit by a marketing company which suggested dialling back on puppy pictures and posting more about operational police work.
The audit included a manual assessment of thousands of comments on police social media channels.
It found the Southern district (Otago and Southland) had among the lowest levels of positive comments in the country, at just 4 per cent, compared with a high of 17 per cent in Waitemata.
Information about the audit, undertaken by social media marketing company Socialites last year, was obtained by the Otago Daily Times under the Official Information Act.
Police are prolific on their official social media pages, particularly Facebook, where posts about police dogs and puppies are frequent.
