The Government's new offender levy has reached its first-year target of $2 million nearly five months earlier than expected.
The levy, brought in last July, requires all convicted offenders to pay $50 when they are sentenced.
The money is used to fund entitlements and services for victims of serious crime.
Justice Minister Simon Power says his ministry's estimate that it would bring in $2 million in its first year was based on the assumption that 42% of offenders would pay the levy.
In fact, he says, 55% have paid so far.
