The epidemiology and control of tuberculosis in New Zealand is discussed. The source of infection for cattle and deer is the wild possum (Trichosurus vulpecula). The number of tuberculin reactors increased from 3610 in 1980-81 testing season, to 6011 in the 1989-90 season. The number of cattle herds placed under movement control restriction because of tuberculosis increased from 511 in March 1981 to 1246 in March 1991.
