Depends what you're talking about, if its compared on a per capita ratio then it could be debatable.
For example:
"The Central police district, which includes Palmerston North and Wanganui, recorded a 1.4 per cent drop in crime, from 34,934 offences in 2002 to 34,452, its seventh consecutive decrease since 1996. The drop per 10,000 population was 1.5 per cent. Palmerston North area commander Inspector Pat Handcock said the city had experienced a 0.7 per cent increase in crime in 2003 but had recorded a 6 per cent drop in total crime during the first month of 2004."
This is a primarily rural area, with a 0.7 per cent increase in crime in 2003. If you dug deeper into the figures I wouldn't be suprised if the rural crime rates were higher per head than the urban, especially in the violent crimes area. Most of our gun related crimes/murders occur in rural areas (where gun ownership is more prevelant).
To put Wellington in perspective, the population is around 300,000 (I think), to get into a rural area only takes 10-15 minutes drive from the city center to rural farmland.
