Deer hunters are advised to take extra care in the forests over the next month, as the roar begins.
Traditionally the roar, which starts near the end of March and will continue until the end of April, is the busiest time of year for deer hunting, and this year it coincides with the Easter holiday period, when many people will be camping and tramping on conservation land.
Deer Stalkers Association iwi spokesman Alec McIvor said fatalities happened when hunters did not take an extra second to establish their target.
"The main thing is, if you are with a hunting partner, make sure you identify your target.
"There's lots of hunters out in the bush at this time of year, being the roar, so take extra care. Most hunters hunt alone or with a mate, these incidents happen, 99 per cent of the time, when two hunters separate. Most of the time it's mates shooting a mate or a son shooting a dad or vice versa.
