Abstract
We examined the jaw size, age and sex distribution of 324 red deer constitu ting a comprehensive record of all recreational hunting kills made by a sin gle hunter of the Tararua ranges of North Island New Zealand over a period 20 years (1976-1996). The proportion of stags shot at times other than the rut (March - April) was not significantly different to that in a sample of deer obtained by commercial helicopter hunting and did not change significa ntly after the first three years of hunting regardless of any effect of hel icopter hunting. Conversely, significantly greater numbers of males were sh ot during the months of the rut and this proportion increased significantly after the first three years of hunting presumably as a result of increased selectivity and or skill. The recreational hunter harvested significantly greater numbers of older animals than did helicopter hunters. The proportio n of older animals shot during, and at times other than the rut, increased significantly after the first three years of hunting. Analysis of jaw lengt h versus age showed a significant increase in the jaw size of age cohorts b orn after 1976 i. e. after an increase in culling effort and was indicative of a general decline in population density during the period of the study.
