Cystic fibrosis in New Zealand: incidence and mortality data.

The incidence of and mortality from cystic fibrosis in New Zealand for 
the years 1965-1971 have been reviewed. Data were obtained from hospital 
admission and death records. All of the 171 cases were of 
European parentage except for one part-Maori child. The minimum incidence of 
cystic fibrosis in the European population (one in 3185 live births) 
is comparable with that in other populations of similar background but 
somewhat lower than that derived by Becroft (1968). The data show 
that, during the period of the survey, approximately 30 percent of 
cystic fibrosis suffereres died at less than 12 months of age.
