Labour is using the latest Police Workplace Survey to support its call for more frontline officers.
Police spokesman Stuart Nash says it shows more than 55 percent say they have an unacceptable level of stress in their jobs.
And only 42 percent believe the police deliver on the promises they make to the public.
"The survey shows what we already know - that our police are committed to the work they do and feel a sense of commitment to their job," Mr Nash said.
"These results tell us that staff want to deliver on their promises and are committed to crime prevention and resolution.
"They simply don't have the resources to deliver."
