Waikato and Bay of Plenty Police Association regional director Wayne Aberhart said the figures were concerning.
"Twenty years ago I would have gone with that and gone, 'that's probably right' but things have changed. Even in the last 10 years the police culture has changed remarkably," he said. "I'm surprised at that."
The Bay district scored a 67 per cent "agreement" rate across all questions.
The overall results were largely unchanged from the previous year and slightly higher than the national average.
Overall, the Western Bay of Plenty recorded some of the lowest scores in the district.
Survey results dipped below the national average, most notably for workplace communication, the belief that NZ police were interested in the wellbeing and opinions of staff, and enjoyment of the job.
Bay of Plenty district commander Superintendent Glenn Dunbier said respect and diversity were taken "extremely seriously" and he was confident that strong processes were in place to deal with inappropriate workplace behaviour. Confidentiality of the survey limited staff's ability to demonstrate that they had been dealt with appropriately, Mr Dunbier said.
"It goes without saying that we would like to see our staff having greater belief in the processes, regardless of gender, and we will continue to work hard to nurture that trust."
Western Bay area commander Inspector Clifford Paxton said results would always show "some areas higher and some lower".
"We strive continually towards achieving a healthy workplace, where our members enjoy coming to work, the work is meaningful and they feel valued and recognised."
Nationally, the survey showed overall results had slipped compared to 2012. It also revealed a widening gap between men and women in the safe reporting and effective handling of inappropriate workplace conduct.
"Not only have females held a less favourable opinion on these questions year on year, the gender gaps widened in 2012 and the size of these gaps remained virtually unchanged in 2013," the survey analysts wrote.
This year, 19 per cent of female police had experienced or witnessed inappropriate workplace conduct, compared to 14.7 per cent of males.
