More than one in five convicted Hawke's Bay offenders have not paid a $50 levy designed to support victims of serious crime.
Ministry of Justice figures show 74 per cent of offender levies imposed at Hastings and 80 per cent imposed at Napier District Courts in the first four months of the year have been paid.
The figure is down from 86 per cent in Hastings and 81 per cent in Napier during 2012.
Ministry of Justice operational services spokesman Nigel Fyfe said the offender levy was not necessarily paid in the same year it was imposed as some offenders were subject to a payment arrangement, while others were still in prison.
By April, more than $500,000 had been raised from Hawke's Bay offenders since the scheme's 2010 inception.
Victim Support chief executive Tony Paine said the levy was now "a really significant and positive part of the justice system".
"It's generating a significant amount of money, almost all of which is being channelled directly back into the pockets of victims of the very most serious crimes, particularly homicide and sexual violence."
It was appropriate offenders contributed to making things easier for victims, Mr Paine said.
"Even if their crime hasn't involved a victim, it just helps contribute to making the world a better place."
To date, $11.8 million nationwide has been raised by the levy, helping more than 4000 victims of serious crime.
Minister of Justice Judith Collins said it was critical that victims had the support they needed to be part of the justice process, and to help them recover and rebuild their lives.
The $50 levy is imposed on all offenders at sentencing and contributes to support services for crime victims.
A single levy is imposed, regardless of how many charges for which a person is sentenced.
Sensible Sentencing Trust spokesman Garth McVicar said the levy was a trust initiative.
"We wanted to move victims to having more of a voice in the justice system, but we didn't want to copy-cat the legal aid system. We felt it was wrong that the taxpayer should have to fund it so we wanted it to be funded by the people who were causing the harm - the offenders."
Mr McVicar said he hoped the current 14 per cent non-repayment rate was due to offenders being in prison, not "some giving their fingers to the system".
Offender levies cannot be collected from serving inmates but prisoners are required to pay up on release.
The order of payment priority is that reparation is paid first, followed by the levy, then any fines the person might owe.
In the 2011/12 financial year, $1.2 million was spent supporting 834 victims through the sexual violence court support service, Justice Ministry figures show.
In the same period, $115,000 was spent supporting 36 victims through the ACC additional funeral grant for families of homicide victims.
Also funded is a court attendance grant for up to five adult members of a homicide victim's family to attend proceedings and a discretionary grant for victims of sexual violence.
