Ensuring the safe and efficient transport of perishable goods requires a well-managed cold chain. Chilled transport in NZ is essential for industries like food, pharmaceuticals, and medical logistics, where maintaining the right temperature prevents spoilage and contamination. In this article, we’ll explore best practices for cold chain success and how businesses can optimise their logistics operations.

1. What Is Chilled Transport?

Chilled transport refers to the movement of temperature-sensitive products using refrigerated vehicles, insulated packaging, and monitoring systems. It ensures that perishable goods remain within a specific temperature range throughout transit.

Key temperature categories include:

• Frozen (-18°C to -30°C) – Ideal for frozen meats, ice cream, and some pharmaceuticals.
  
  

• Chilled (0°C to 5°C) – Used for dairy, fresh produce, and vaccines.
  
  

• Controlled ambient (15°C to 25°C) – Suitable for certain pharmaceuticals, cosmetics, and specialty foods.
  
  

2. Industries That Rely on Chilled Transport in NZ

a) Food and Beverage Industry

The food industry is one of the largest users of chilled transport in NZ. Key sectors include:

• Supermarkets and grocery stores
  
  

• Restaurants and catering services
  
  

• Dairy, meat, and seafood suppliers
  
  

• Beverage manufacturers (wine, kombucha, cold-pressed juices)
  
  

b) Pharmaceuticals and Medical Logistics

Temperature control is crucial for pharmaceutical and medical supplies, including:

• Vaccines, insulin, and prescription medications
  
  

• Blood, plasma, and biological samples
  
  

• Laboratory and research materials
  
  

c) Fresh Produce and Horticulture

New Zealand’s agricultural sector depends on chilled transport to maintain product freshness, including:

• Cut flowers and plants
  
  

• Fresh fruits and vegetables
  
  

• Specialty herbs and organic produce
  
  

d) E-Commerce and Grocery Deliveries

Online food and grocery deliveries require chilled transport to ensure that perishable products arrive in optimal condition.

3. Best Practices for Chilled Transport in NZ

a) Temperature Monitoring and Control

Maintaining consistent temperatures is the foundation of chilled transport. Best practices include:

• Real-time temperature monitoring with GPS tracking.
  
  

• Automated alerts for temperature fluctuations.
  
  

• Regular calibration of refrigeration units to ensure accuracy.
  
  

b) Proper Packaging and Insulation

The right packaging prevents temperature loss and protects products during transit. Common solutions include:

• Insulated containers and gel packs for smaller deliveries.
  
  

• Refrigerated pallets and thermal blankets for large shipments.
  
  

• Dry ice and phase-change materials for frozen products.
  
  

c) Efficient Loading and Unloading Procedures

To minimise temperature fluctuations, businesses should:

• Use pre-cooled storage areas before loading.
  
  

• Load perishable items last to reduce exposure to external temperatures.
  
  

• Implement quick unloading procedures at delivery points.
  
  

d) Regulatory Compliance and Safety Standards

Businesses involved in chilled transport in NZ must comply with:

• New Zealand Food Safety Authority (NZFSA) regulations.
  
  

• Hazard Analysis and Critical Control Points (HACCP) protocols.
  
  

• Good Distribution Practice (GDP) standards for pharmaceuticals.
  
  

e) Preventative Maintenance of Refrigerated Vehicles

Regular maintenance ensures that refrigerated trucks and vans operate efficiently. Important steps include:

• Routine inspections of cooling units to prevent failures.
  
  

• Checking door seals to maintain airtight insulation.
  
  

• Regular cleaning of refrigeration components to prevent contamination.
