Hosted by the New Zealand Hereford Association, from March 9-13, delegates will hear sector speakers, and industry reports from the various countries.
As part of their itinerary they will visit Walter Peak Station, near Queenstown, as well as Earnscleugh Station and Locharburn Hereford studs, near Alexandra and Cromwell.
Media spokeswoman Debbie Knight said judging from early bird registrations, attendance looked good.
''It is the first time in 30 years it has been in New Zealand,'' she said.
''We are expecting people to come here from all over the place, including from Australia, United States and United Kingdom.
''The idea is to come here and learn off each other.
''They will share country reports so we can find out where we are in terms of growing Herefords.''
In addition, at least nine teams from around the world will compete in the inaugural Young Breeders Competition.
New Zealand will have two teams representing the association and Future Beef.
Ms Knight said they would compete in various modules including animal preparation, showing and handling at the Wanaka A&P Show, as well as attend the conference and visit some of the region's studs.
Delegates also have the chance to go on pre- and post-conference tours, which visit studs in both islands.
They include Waikaka Station, Kane Farms, Limehills Herefords, Waiau Herefords and Monymusk Polled Herefords.
One of the conference organisers, Gray Pannett, of Limehills Hereford stud, Teviot, said delegates would be visiting their property.
''We will be showing a range of age groups of stock,'' he said.
''They will be doing about 12 places in four days, which is not too bad as they will have a good look around.''
Association general manager Posy Moody said there were more international delegates registered than there were from New Zealand.
''We encourage New Zealanders to register,'' she said.
She said during stud visits, where Herefords were farmed in all types of environments, New Zealand breeders could showcase their high quality genetics, which could generate semen sales for breeders.
''We've made sure our international visitors will have plenty of opportunity to get out and about by offering farm visits to renowned high country studs so they can observe stock in their natural environment.
''We're offering our attendees the chance to hear from a wide array of our inspirational and knowledgeable speakers on varying topics including regenerative grazing management, and beef cattle, carbon and the environment.
''It's going to be a very exciting time for breeders, as they enjoy reconnecting with their clients and friends who share the same passion for good breeding.''
