| Abstract: | 
We estimate that the total costs of crime in New Zealand in 2003/04 amounted 
to $9.1 billion. Of this, the private sector incurred $7 billion in costs and 
the public sector $2.1 billion. Offences against private property are the most 
common crimes but offences against the person are the most costly, accounting 
for 45% of the total estimated costs of crime. Empirically-based measures like 
those presented here – the total and average costs of crime by category – are 
a useful aid to policy analysis around criminal justice operations and 
settings. However, care needs to be taken when interpreting these results 
because they rely considerably on assumptions, including the assumed volume of 
actual crime, and the costs that crime imposes on victims. This difficulty in 
constructing robust estimates also implies that care should be taken not to 
draw conclusions about whether the Government should be putting more or less 
resources into any specific categories of crime, based on their relative costs 
alone. |
