New Zealand sheep farming is fundamentally centred around managing the dynamic changes in pasture quality and animal biology across the year to sustainably convert grass into marketable meat and wool. Understanding New Zealand sheep 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 breeds they run, how farms are set up, how pasture supports production, and the organisations and regulations that underpin the sector.
