The number of people charged and convicted of driving under the influence in this dataset will differ from that available in the 'Adults prosecuted in court - most serious offence' and 'Adults convicted in court by sentence type - most serious offence' tables on Stats NZ in the NZ.Stat tool. This dataset counts the total number of people charged and the total number of people convicted for a driving under the influence offence in a year, whereas the NZ.Stat tables show a person's most serious offence in a year (which may be for an offence other than driving under the influence). Additionally, this data counts all people, whereas the NZ.Stat tables display data separately for children and young people and for adults.
This data counts people charged in court. It does not include instances (since 1 December 2014) where a person received an infringement notice for driving under the influence of alcohol.
Changes to data collection/processing
From 29 April 2016, the Ministry of Justice sources courts data from the new Enterprise Data Warehouse (EDW), rather than the justice sector data warehouse (ISIS) used over recent years. Changes in data processing may cause small differences if compared current output with similar results produced before 29 April 2016.
Prior to March 2017 these statistics were published as 'drink driving' offences, which excluded offences for 'driving causing death'.
