The police union says almost half of all Victorian police officers have been assaulted in the past year, with ice addiction a major contributing factor.

The Police Association of Victoria secretary Ron Iddles says there has been a concerning rise in attacks on police and emergency service workers.

"Forty-eight per cent of our members have been assaulted in some way in the last 12 months," he told 3AW on Monday.

Trying to subdue highly aggressive and violent offenders on ice is becoming difficult, Mr Iddles says.

"They will often try and resist arrest and become violent," he said in a statement.

"This often requires five or six officers, rather than just one or two, which is the norm."

Mr Iddles also pointed to ballooning figures for resisting arrest and assaults against officers.

Victoria Police confirmed there has been a 153.5 per cent increase in resisting arrest or hindering an officer from 2014/15 to 2015/16.

But the jump was because police began including new "evade police" figures into the mix.

After July 2015, police introduced strict rules preventing police engaging in car chases, which increased the amount of "evade police" offences.

"The increase can be explained by the inclusion of 'evade police' offences, which are included in the 'resist or hinder officer' statistic, and account for a total of 5385 incidents (out of a 9285 total)," a police spokeswoman told AAP.

Those pursuit rules have since been relaxed.

Mr Iddles called on Victoria Police to deploy more frontline police so offenders are deterred from "taking on police" while also providing officers with more resources on the ground.

In August, the Andrews government said 700 people will graduate from the police academy in the next 12 months.

The budget also included funds for 406 new police officers.
