Fallow Deer were among the first deer to be introduced to New Zealand and can be found in both North and South Islands. Males (Bucks) grow to 60-85kg in weight. Only Bucks develop antlers which they cast each year between October and November. The replacement set they develop by the following February. The rut lasts from April - May which typically sees small groups of Bucks and Does come together rather than individual males herding a harem.
