2. New Cases notified as Tuberculous to the Medical Officer of Health during 1945 are scheduled and compared with cases notified in years 1943 and 1944:

Total new cases, both races, notified: 1943, 2,603 ; 1944, 2,254 ; 1945, 2,572. Some of these cases have been found to be non-tuberculous and consequently deregistered. 3. Incidence Rates, all Forms: — Rates per 1,000 Population. The known incidence for Europeans— 1945. 1944.

The European incidence is 11-13 times the annual deaths. Figure for 1944, 9-7. The Maori incidence is 6-4 times the annual deaths. Figure for 1944, 5-7. The combined race incidence is 9-3 times the annual deaths. Figure for 1944, 8-0. The incidence of the combined races is approaching the figure 10 that is usually accepted as the ratio of cases to deaths in other countries. The New Zealand European incidence is higher than this figure. 4. The 1945 Mortality Returns for Tuberculosis, as supplied by the Government Statistician, are scheduled as follows
