The proportion of Maori officers in the police has remained static over the past two years and stands at 11%.
The figures are contained in the New Zealand Police annual report for 2011.
It notes, however, that the ethnic profile of new recruits is moving towards mirroring the make-up of the New Zealand population.
According to the report, Maori trainees made up 15% of recruits who graduated from the Royal New Zealand Police College in Porirua in 2010.
That figure compares to 8.5% for Pacific officers and 6% for Asian constables.
