Ive just been doing some research for you. Im not sure if I am allowed to post links, so wont unless I get permission, but will just list the guys who I think will give you a great time. Its important to know that the NZ guiding industry is unregulated, and the organisation representing them- The NZPHGA- actually has no clout as far as ethics or behaviour gos.
With that in mind, I have stuck to recommending you guys who I have met or talked with somewhat and who have a reputation as honest, positive guides.
Chris Mcarthy of Lake Hawea Hunting Safaris.- Chris has been in the game a long time and understands his client well. he spends most off seasons in NZ, guiding in the states or Canada for mountain game.
Marcus Pinny, of wilderness Trophy hunting- Note hes mostly been a Tahr and Chamois Guide, but I hear he has secured a fantastic fallow property, and his website says coming soon on fallow, so He would be worth talking too.
Joseph Peter Of Hard yards Hunting- Joseph only offers free range hunts and is one of the hardest working guides out there- You will see again there is not alot of info about fallow. Mostly this is because the average hunter coming to NZ is after a red stag, and other hunts are lower income earners that are often tagged onto the red stag hunt.
Its worth contacting all these guys to see what they can offer you.
And finally
Gerald Telford, of Telford hunting and fishing- I know hes got some great fallow areas, and is well respected and has been guiding most of his life. He's also done a bit of bow hunting himself. I spent a day hunting pheasants with him on my place last year and got on well with him.
Some issues- the hunting industry has been smashed by our countries response to Covid, alot of the guides have been forced to take up other jobs. In some areas there will not have been any restocking of animals, but if you are after free range hunting, then that should not be an issue. The upside is that alot of game has not been hunted for a couple of years and the first season after this all ends will see some cracker heads taken I suspect.
Also if you are in the country for a while and end up in my area, Ill happily host you and do some hunting at my place if you are keen.
