That was soon after Collins had said the ideal of having one officer for every 500 New Zealanders had slipped to one for every 526.
It also followed a pledge by NZ First leader Winston Peters that if his party was in government another 1000 police would be trained.
After her speech, Collins indicated to reporters that she was asking for a substantial increase.
Greg O'Connor, the association's outgoing president, suggested there could be an extra 450 officers.
Since National came to power, police numbers have increased by more than 600.
Collins used her speech to discuss recent family violence initiatives, saying the government was committed to reducing the damage it causes.
She also praised police for the way they're targeting illegal drugs.
