Those who don't buy a license, Mr van Dorp explained, are just riding on the back of those conscienscious hunters who contrinute directly to Fish & Game's management of game bird habitats and resources.
Fish & Game staff also teamed up with Police to ensure firearms regulations were being followed, and found a small number of hunters consuming alcohol against the 'guns and alcohol don't mix,' advice and laws.
"Most hunters have got the message to leave the beers until hunting is over and the guns are secured away but we still need to get it through to a small minority," Mr van Dorp said. "They're putting themselves and anyone nearby at risk."
Following the late-summer drought, the Eastern Region season for mallard and grey ducks has been shortened to four weeks, although upland game birds - including pheasant and quail, paradise shelduck and black swan - have a longer season extending into July and August depending on the species.
Results from the opening weekend supported indications mallard numbers were down across the region, although many hunters managed to collect their limit of paradise ducks, especially in the Eastern Bay and East Cape areas, while officers also reported excellent numbers of pheasants in some areas.
"We saw flocks of paradise ducks as thick as flies in parts of the Gisborne and East Coast area and there were large flocks in paddocks out the back of Whakatane," Mr van Dorp said. "Even though overall bags were only average or below average, most hunters we spoke to were happy with the opening weekend and had thoroughly enjoyed themselves, especially once the weather front came through when the ducks were generally a bit more mobile and flying lower."
A handful of banded birds were also seen by Fish & Game officers and they want to hear from any hunters who harvested more, by writing, phoning or emailing with details of the bird and its band number. They also want information on any birds shot which have a radio transmitter fitted, as part of an earlier tracking study.
