5. Dairy Key Organisations

Key Organsiations

The New Zealand dairy sector is supported and governed by a network of government agencies, industry bodies, milk processors, professional regulators, and farmer organisations. These entities have distinct roles spanning regulation, food safety, biosecurity, milk processing, industry-good functions, and workforce and leadership development.

Central Government and Regulatory Agencies

Ministry for Primary Industries (MPI)

The Ministry for Primary Industries (MPI) is the primary national regulator of the dairy sector. Its responsibilities include:

animal welfare regulation and enforcement
biosecurity surveillance, readiness, and response
administration of the NAIT system
regulation of veterinary medicines under the ACVM Act
• dairy food safety oversight, including Risk Management Programmes
regulatory oversight of NZCP1 compliance

MPI sets national standards, conducts audits and investigations, and leads responses to major biosecurity and food safety incidents.

Regional Councils

Regional councils regulate the environmental impacts of dairy farming under the Resource Management Act 1991. Their responsibilities include:

setting regional freshwater and nutrient limits
issuing and monitoring resource consents
regulating effluent storage and land application
enforcing land-use and discharge rules

Biosecurity system delivery

OSPRI

OSPRI New Zealand is responsible for delivering national animal disease and traceability programmes on behalf of government and industry, including:

bovine tuberculosis eradication
operational delivery of the NAIT system

OSPRI operates under contractual arrangements with MPI and industry partners and plays a central role in disease surveillance and movement control.

Industry Good Organisations

DairyNZ

DairyNZ is the statutory industry-good organisation funded by a levy on dairy farmers. It does not regulate but provides sector-wide functions, including:

research and development
farmer education and extension
biosecurity preparedness support
workforce development and wellbeing programmes
environmental sustainability initiatives

DairyNZ acts as a key interface between farmers, researchers, processors, and government.

Farmer Representation and Sector Networks

Federated Farmers

Federated Farmers is the principal advocacy organisation representing farmers’ interests. Within the dairy sector, it provides:

policy advocacy on regulation and compliance
representation in government consultation processes
coordination of farmer perspectives on proposed reforms

Dairy Women's Network

The Dairy Women’s Network supports leadership, governance, and professional development across the dairy sector. It focuses on capability building, connection, and inclusion rather than regulation or advocacy.

Future Farmers

Future Farmers is a cross-sector organisation focused on developing the next generation of farmers and agribusiness professionals. It contributes to workforce capability, leadership development, and long-term sector sustainability.

Dairy Processors

Milk processing and export are dominated by a small number of processors, each operating supplier assurance programmes aligned with MPI food safety requirements, including NZCP1 verification.

registration and oversight of veterinarians

defining requirements for veterinary–client–patient relationships
guidance on veterinary authorisation and Restricted Veterinary Medicines
