This morning, they left home at 5.15am and travelled to their shooting spot.
Shooting would begin at 6.45am and had to stop by 7pm.
In Central Otago they would mainly be shooting mallard but had a chance of paradise ducks, canadian geese, and shovelers.
After the duo had finished shooting ducks, their game season would continue.
Quail season would open on June 2 and finish in August, and they would also participate in pheasant shooting in Waimate.There was one key element to the whole season, Mr Southee said.
"You have to do it right. You scare ducks away if you don't."
Central Otago police urged duck-shooters to keep alcohol consumption to a minimum this weekend.
Acting Central Otago sub-area supervisor Detective Sergeant Derek Shaw warned shooters not to drink alcohol if they were using firearms or driving.
"Duck-shooting is a long held tradition in the Central Otago area but often that comes with a combination of firearms, vehicles and sometimes alcohol, it's just about the responsible use of all three.
"If you're using firearms you can't use alcohol."
No extra police would be rostered on, but patrols would focus on rural areas near duck-shooting hotspots.
Cromwell Fish and Game officer Cliff Halford said it was important to respect the bag limits and also to have an "enjoyable weekend" and get home safely.
