New Zealand Police's 2020/21 annual report shows mental health-related events have increased by 60 per cent over the past five years and are predicted to increase by a further 44 per cent by 2025.
Superintendent Lane Todd said these calls take a significant amount of police time.
He said police resources are going towards up to 20 mental health and suicide callouts a day.
"Officers do get training and advice on how to deal with these situations but not at the same level as a psychologist," Todd said.
There's now a push for change as police callouts for mental health issues rise steadily.
Police Association president Chris Cahill said officers are not mental health experts and shouldn't be the first port of call to respond to mental health crisis callouts.
People often contact police looking for help because it's a 24/7 service that deals with emergencies, Cahill said.
He believes police officers are not the right people for these calls, as they're not appropriately trained.
"These calls are making the job difficult for officers," Cahill said.
Last year, police, Wellington Free ambulance and Capital and Coast District Health Board trialled a co-response team to respond to emergency mental health calls in Wellington.
The findings have found the pilot scheme was a success.
Cahill said this shows there are much better outcomes for people experiencing mental distress if experts are working with police and can take over the situation when required.
