I want to herd sheep in New Zealand. Is there any way?

Dear, what is your situation? My understanding is: you want to work in New Zealand.

I personally recommend you to study in New Zealand. This is the most formal way. If this is the case, you can not only herd sheep, but also learn many other things. Because New Zealand is a country with a large number of immigrants, it is possible for you to immigrate after completing your studies. This is the best way.

Wish you good luck. I can also explain it to you in detail.
