Hi Charlotte, welcome, there are several members here in NZ.
Cheese making is very tough to master, especially when you can't apprentise from others and only have a book, thus this Website/Forum is so useful.
Most people here start with simple lactic acid cheese like Crem Cheese or Light Cream Cheese also called American Neufchatel in this forum, the cream or milk is held in a vat (many people use a stainless steel stockpot) and then hung in cheesecloth, simple. Then build on their knowledge, experience, and equpment from there. Also, if you are going big and wholesaling or retailing your cheese then you should many say you should concentrate on one or two cheeses with a specialty.
How much milk are you expecting and when do the cows arrive and how much of the milk are you expecting to use to make cheese? Also, have you bought any cheese making equipment and ingredients yet?
Lastly, if you have any spare time now, I suggest you buy some milk (or preferably raw from neighbor dairies) and start practicing making cheese now.
Don't forget to have fun.
