Data from an Auckland coronary heart disease register have been used to assess the validity of Maori mortality statistics produced by the National Health Statistics Centre. During the period 1983-4, 804 people aged 35-64 years and resident in the Auckland statistical region, were identified by both the register and death registration data as having died of coronary heart disease. The coronary heart disease register failed to classify the ethnicity of thirteen of these people. Of the remaining 791 cases, the register classified 80 as Maori while only 44 were classified as Maori in the national death registration data; over the period 1983-4 Maori mortality due to coronary heart disease in the Auckland statistical region was understated by 82% (80-44/44). Although some of this discrepancy may be due to differences in classification of ethnicity, the major reason for the understatement is missing information on the death registration form. Simple changes in the documentation of ethnicity could markedly reduce the degree of underreporting.
来自奥克兰冠心病登记处的数据已被用于评估国家卫生统计中心编制的毛利人死亡率统计数据的有效性。在1983 - 1984年期间，登记处和死亡登记数据均确认，在奥克兰统计区居住的804名35 - 64岁的人死于冠心病。冠心病登记处未能对其中13人的种族进行分类。在其余791例病例中，登记处将80例归类为毛利人，而在国家死亡登记数据中只有44例被归类为毛利人；在1983 - 1984年期间，奥克兰统计区因冠心病导致的毛利人死亡率被低估了82%（80 - 44/44）。尽管这种差异部分可能归因于种族分类的不同，但低估的主要原因是死亡登记表上缺少信息。种族记录方面的简单改变可能会显著降低漏报程度。
