In New Zealand, there are local beekeepers clubs, and Im a member of my local Manawatu club, but there is also a national association (NBA) which all beekeepers need to join - costs about $20 a year for registration of up to 10 hives.
In return, you get hive health checks from other NBA members. Means if I miss seeing disease or a problem one of my fellow beekpers may see it for me. Sounds a bit invasive of my privacy, but the reality is very different. Great way to meet other keepers , share techniques and a great way to keep healthy hives . I'm all for it.
