New Zealand Port Activity: Daily Shipment Estimates and Port Calls

PortWatch provides daily port call counts and shipment volume estimates in metric tons for maritime hubs across New Zealand. This time-series data tracks both incoming and outgoing trade flows, with records updated through March 2026. It serves as a high-frequency indicator of national maritime logistics and trade activity.

Use Cases

• Modeling daily trade volatility using port call counts
• Estimating national import and export trends via incoming and outgoing shipment volume metrics
• Analyzing seasonal logistics patterns in New Zealand maritime infrastructure

Strengths

• Daily temporal granularity for maritime activity
• Dual-flow tracking of both incoming and outgoing shipment volumes
• Standardized metric ton estimates for cargo weight

Limitations

• Shipment volumes are estimates rather than verified primary customs records
• Metadata does not specify the number of unique ports covered
