NZ Post

Goal

Query NZ Post public APIs for parcel tracking, location search (PostShops, parcel-collect points, postboxes), and address/postcode lookup. No authentication required.

Use this when

• A user wants to know where their NZ Post parcel is
• A user asks if a parcel has been delivered
• A user wants to see the full tracking history for a shipment
• A user has a domestic NZ Post tracking number or an international inbound tracking number routed through NZ Post
• A user asks "where is my package?" with an NZ Post or CourierPost number
• A user wants to find a PostShop, parcel-collect point, or postbox near a location
• A user wants to look up a New Zealand address or postcode

Do not use this for

• DHL, FedEx, UPS, or other non-NZ Post carriers
• NZ Post MyMail/standard letters (untracked items)
• Booking or scheduling courier pickups
• Redirecting or modifying delivery instructions

Preferred workflow

1. Run track <number> for a human-readable status summary and event timeline
2. Run locations --near "SUBURB" to find nearby NZ Post facilities
3. Run address "QUERY" to look up NZ delivery addresses and postcodes
4. Add --json to any command for machine-readable output suitable for piping

python3 skills/nzpost/scripts/cli.py <command> [flags]
