Fonterra Co-operative Group

Fonterra, one of the world's largest dairy exporters, collects 22 billion liters of milk per season across more than 100 plants spanning 26 sites in New Zealand. Managing quality, throughput, and compliance across a distributed operation of this scale — where raw milk must move from farm to processing to export within strict time and temperature windows — requires real-time visibility that siloed, on-premise systems could not deliver. Without unified access to production data, workers had no consistent means to monitor equipment health or identify bottlenecks across sites, leaving OEE improvement opportunities unrealized and operational decisions dependent on lagged, fragmented reporting.

Fonterra partnered with Rockwell Automation to execute an edge-to-cloud digital transformation across its multi-site New Zealand manufacturing network. IoT sensors embedded across production lines stream real-time telemetry — equipment state, throughput rates, quality parameters — up through edge control hardware to Microsoft cloud infrastructure for storage and cross-site data sharing. PTC's ThingWorx IIoT application development platform serves as the integration layer, normalizing data from disparate plant control systems into a unified operational view. Rather than replacing legacy automation wholesale, the architecture layered connectivity on top of existing Rockwell Automation control hardware, reducing deployment risk and preserving prior capital investment. The result is a device-agnostic interface giving workers access to live production data from any location on any device.

The transformation delivered a 20% improvement in OEE across Fonterra's manufacturing facilities — a substantial gain for a co-operative processing 22 billion liters of milk per season, where each point of equipment effectiveness translates directly to capacity, yield, and energy efficiency.

Key outcomes:

• 20% OEE improvement across 100+ plants at 26 New Zealand sites
• Frontline workers gained live production data access on any device, on-site or remotely
• Decision-making across the full farm-to-table value chain shifted from lagged reporting to real-time operational awareness
• Standardized data access reduced information asymmetry between plant floor operators and operations managers

• Multi-site food manufacturers can achieve significant OEE gains by layering IoT connectivity over existing control infrastructure rather than replacing it, preserving capital investment while accelerating deployment.
• An edge-to-cloud architecture — sensors at the plant, unified storage in the cloud — enables real-time visibility across geographically distributed operations without centralizing processing overhead.
• A dedicated IIoT application platform (Fonterra used PTC ThingWorx) is critical for normalizing data from heterogeneous plant systems into a single operational view at scale.
• Device-agnostic data access is a key adoption driver: workers who can check line status from any device are more likely to act on production data in real time.
• For dairy and food processors, OEE improvements at this scale directly affect seasonal volume commitments, product yield, and cost per unit.
