A range of data, including milksolids production and rainfall, is now collected from farms in Greymouth, Westport, Ikamatua and Kowhitirangi. Every season the farms are analysed to identify trends and a comparison is made between seasons (going back to 2008). This information is shared through field days, discussion groups, and weekly DairyNZ Farmwatch reports.

The project is supported by DairyNZ, Westland Milk Products, CRV-Ambreed and Ravensdown - ARL Labs
