FuelClock NZ

Goal

Query live New Zealand fuel price and supply data from fuelclock.nz through a CLI that is easy for agents to script and easy for humans to scan. Includes geopolitical shipping risk markets and recent NZ fuel headlines.

Use this when

• A user asks about current NZ petrol, diesel, or premium fuel prices
• A user wants to know whether NZ fuel supply is tight or below MSO thresholds
• A user asks what tankers are en route to New Zealand
• A user wants a quick fuel situation summary focused on prices, supply, and vessels
• A user asks about geopolitical shipping risk markets relevant to NZ fuel supply
• A user wants recent NZ fuel headlines

Do not use this for

• Fuel prices outside New Zealand
• Electricity, gas, or LPG pricing
• Vehicle fuel efficiency calculations
• Forecasting future fuel prices beyond the live observed data

Preferred workflow

1. Run scripts/cli.py with the narrowest subcommand that answers the task
2. Use summary for a quick situational briefing across prices, supply, and vessels
3. Use watch for a quick briefing across geopolitical risk markets and recent headlines
4. Use default human output for direct answers
5. Use --json when another tool or agent needs machine-readable output

CLI

Run with:

python3 skills/fuelclock-nz/scripts/cli.py <command> [flags]

summary [--json]

Resources

• CLI entrypoint: scripts/cli.py
• Live smoke test: scripts/smoke_test.py

Notes

• No API key required
• Pure Python 3 standard library (urllib); no third-party dependencies
• Default output is human-readable and filtered for quick answers
• --json output is intended for chaining into other tools or agent steps
• FuelClock supply data and MBIE stock data are related but not identical, FuelClock applies its own live supply model on top of source data
• Geopolitical risk probabilities are market yes-prices from Polymarket-style data, not direct NZ fuel risk scores
