Assault in New Zealand

Offence: refers to any act or omission by a person/organisation or persons/organisations for which a penalty could be imposed by the New Zealand legal system. Offences in this collection are defined by the 2011 edition of the Australian and New Zealand Standard Offence Classification (ANZSOC).
Offender: refers to a person or organisation Police apprehend because Police allege the person or organisation is involved in a criminal incident involving one or more offences.
Proceeding: refers to a legal action initiated against an alleged offender for an offence(s). Police proceedings represent a count for each separate occasion on which police initiate a legal action against an offender. Each proceeding is classified to a principal offence and principal method of proceeding. It does not represent a count of offences.
Proceeding population: the measure involving counting a person once on each day they are proceeded against by police in the reference period, whether by court or non-court action.
