"Hunters will have to work hard to take home dinner for their families with the weekend's weather forecast looking like it will favour the ducks," said Fish & Game's communications manager Don Rood.
"Hunters pray for wind and rain on opening day in the hope that ducks will fly lower but MetService is dashing these hopes with its weekend forecast.
"At this stage, it looks like many regions will be sunny with even frosts likely in some parts of both islands."
Fish & Game is expecting tens of thousands of hunters to be out on wetlands, rivers, and lakes around the country this weekend.
"Game bird hunting has a long tradition in New Zealand, and is a real opportunity for families and mates to get together and harvest birds for the family dinner table," said Mr Rood.
"Nearly 40 thousand game bird hunting licences are sold each year, but the number of hunters is higher as landowners don't need a licence to hunt on their own property."
Mr Rood said Fish & Game urged these landowners to make sure they were familiar with the local regulations and stick to the rules.
"This includes how many birds you can harvest and how many shots you load into your gun. A number of regions have now introduced magazine size restrictions, so make sure you check the rules on www.fishandgame.org.nz for the region you are hunting."
Fish & Game rangers and police will be joining forces over opening weekend to inspect hunters to make sure they have their licences and are following the rules.
The game bird hunting season runs from this Saturday through to August 27.
