Male victims of wrongful death outnumber females, a new police reporting system shows, with men in their 20s most at risk of such deaths.
The culpable death report provides a breakdown of all victims of murder, manslaughter and infanticide.
Using the calender years of 2007 and 2009, it shows there were 65 and 88 culpable deaths respectively.
It says male victims were less likely to be related to, or in a relationship with, their killer than female victims.
The report also notes that children under five were more at risk than adults, and Maori are over-represented in the statistics.
Police say the report will be produced annually and includes the type of offence, where it occurred and the weapon used, as well as offenders' gender, age, ethnicity and their relationship to the victim.
