New Zealand dairy farming is fundamentally centred around managing the dynamic changes in pasture quality and cow biology across the year to sustainably convert grass into marketable milk. Understanding New Zealand dairy farming requires an appreciation of its pasture-driven, seasonal systems as well as the wider industry context in which farms operate. The resources in this section provide a foundation for interpreting on-farm data and management decisions, covering who farms, the cows they milk, how farms are set up, how pasture supports production, and the organisations and regulations that underpin the sector.
