The police are paying out about $2.95 million to nearly 3500 former staff to correct mistakes made in calculating their pay.
While many will only receive a few cents, other will get considerably more.
Eleven former staff would receive more than $20,000 each, with a further 26 getting between $10,000 and $20,000, and 96 getting from $5000 to $10,000, police said.
At the other end of the scale, 485 former staff were owed less than $1, and altogether 807 were owed less than $10, and 2021 less than $200.
The problem arose after the Holidays Act was applied to police in 2004, and was not fixed until the police payment system was upgraded in 2010.
Mistakes made in the pay of staff still working for the police had already been corrected.
