The reports were sometimes incomplete, or had not been sent to the Land Transport Safety Authority (LTSA), which was at that time responsible for the data entry, coding and analysis of crash reports. Injuries were often inaccurately recorded, if at all. Crash locations were often imprecise and Blood/Breath Alcohol levels, and pre-crash speeds, were not recorded in all cases. This combination of under-reporting of casualties and missing data resulted in important crash data not being captured, understating both the actual levels of road trauma and crash contributing factors.
