An Otago University study reveals the fitness of an ageing police force is a concern.
A review of the police competency test was commissioned by police and conducted by the School of Physical Education last year.
Seventy one volunteers took part, all under the age of 50.
It found the test itself needed few changes, but the fitness of older and less physically active officers is a cause for concern.
The average age of a constable has risen from 34 to 39 in the last decade, due mainly to fewer early retirements and lower staff turnover.
Officers need to pass the test every two years.
