Response times for Victoria Police would be recorded and published if the opposition wins the upcoming state election.
Policing is the only emergency service in Victoria that does not measure how long it takes members to attend call-outs or make the data publicly available.
Victorian Police Association secretary Wayne Gatt welcomed the announcement and said the information would help work out where to allocate police.
"We need to record police response times because we need to know where we need to make improvements and where we need to put our resources," he said.
"We will never meet the community's expectations and our own expectations if we don't have a realistic audit of the service we're delivering.
"Recording response times isn't the easy thing to do but it's the right thing."
Shadow Police Minister Brad Battin said the move would increase transparency.
"Every Victorian deserves to know that when they call triple zero, a prompt, professional response is on the way," he said.
Victorian Police Minister Anthony Carbines said recording and publishing response times was an issue for police.
"Those are operational matters and they need to be led by police command."
"We'll keep working with the chief commissioner on all of these matters."
Response times for Victorian ambulance, fire and state emergency services were available.
NSW, Queensland, South Australia, ACT and Western Australia measured police response times but not Victoria or the Northern Territory.
It comes as Roy Morgan polling released on Tuesday showed support for the Australian Labor Party in Victoria dropped slightly but it maintains an election-winning lead.
The ALP leads the Coalition 58-42 on a two-party preferred basis, according to a telephone and online survey of more than 1400 people in August.
More than a third of Victorians intend to vote for an independent or minor party at the November election.
