Two sources of New Zealand statistics on serious traffic accident injuries were compared for the period 1973-82. The official statistics based on Ministry of Transport reports showed consistently lower figures than the supposedly comparable hospital admission statistics from the Department of Health. The reporting ratio in the official statistics had decreased from 66% of the first admissions to hospital in 1973 to 43% in 1982. The highest reporting ratios were observed for drivers and passengers (66% in 1982). For pedestrians it was 48%, for motor cyclists 45% and for bicyclists 15%. A detailed analysis of reporting ratios for specific types of accidents among children showed that for certain accidents almost none of the injured children were recorded in the Ministry of Transport statistics. It is concluded that these statistics present a distorted picture of the nonfatal road toll and that a new statistical reporting system combining information from several sources is needed.
对1973年至1982年期间新西兰严重交通事故受伤情况的两个统计来源进行了比较。基于交通部报告的官方统计数据显示，其数字一直低于卫生部提供的本应具有可比性的医院入院统计数据。官方统计中的报告率已从1973年首次入院人数的66%降至1982年的43%。司机和乘客的报告率最高（1982年为66%）。行人的报告率为48%，摩托车手为45%，骑自行车者为15%。对儿童特定类型事故报告率的详细分析表明，对于某些事故，交通部的统计数据几乎没有记录受伤儿童的情况。得出的结论是，这些统计数据歪曲了非致命道路伤亡情况，需要一个结合多个来源信息的新统计报告系统。
