Figures released to the Otago Daily Times under the Official Information Act showed between June 30, 2008 and July 1, 2009, police staff faced 42 charges.
Nine police staff were convicted, in some cases on multiple charges, one was acquitted, three were discharged without conviction, two had charges withdrawn and two had the cases against them dismissed.
Several cases are still before the courts.
None of the police staff received jail sentences.
One, convicted on two counts of dangerous driving causing injury, was ordered to pay $30,000 to each of two victims, given 100 hours' community work and disqualified from driving for a year.
One employee was sentenced to seven months' home detention and ordered to pay a $5000 fine after being convicted of dangerous driving causing injury.
Southern police district operations manager Inspector Lane Todd said five district staff were stood down or suspended in the same period.
Two Dunedin officers are still before the courts on assault charges.
They are alleged to have punched a man while he was being arrested in March.
Two other officers, who were stood down for five and three months, were the subject of internal investigations, the outcomes of which are confidential.
Another southern officer, whose identity and charges are suppressed, is also still before the District Court.
Police professional standards national manager Superintendent Steve Hinds, from Police National Headquarters, said the charges against police staff across the country in the past year included assault, drink-driving, manslaughter, two of rape, fraudulently obtaining $10,000 and cultivating cannabis.
Police spokesman Jon Neilson said police took allegations of misconduct seriously.
There was a strict code of conduct which set out a clear process for investigating such allegations.
Thirteen police staff were also stood down or suspended pending internal misconduct investigations.
While 22 staff resigned as a result of their conduct last year, Supt Hinds said none had been dismissed.
Of the officers appearing before the courts last year, one person had been on full pay for more than two years while stood down.
Mr Neilson said, depending on the circumstances, staff were either taken off duty while stood down or placed on light desk duties.
The number of staff facing disciplinary proceedings was a small percentage of the total force of 11,881 staff (8776 sworn, 3105 non-sworn), he said.
The number of staff who were the subject of employment investigations following misconduct allegations stayed at about the same level each year, he said.
