Read NZ public transport GTFS static timetables: feeds, stops, routes, trips, scheduled departures and route geometry. Use for Auckland Transport, Metlink (Wellington), BUSIT (Waikato) and Orbus (Otago) schedule baselines, spatial stop queries and timetable analysis.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# NZ GTFS static timetables

Use `scripts/cli.py` for keyless NZ timetable baselines: registered feeds, stops,
routes, trips, scheduled departures and route shapes. Python stdlib only.
AT realtime departures, vehicles and alerts belong to `at-transport`, which
requires the user-supplied `AT_API_KEY`. This skill does not query realtime APIs.

## Workflow

1. Run `feeds --json` to check the registry and feed validity dates; add `--refresh` for a live download.
2. Select `--feed at`, `metlink`, `busit` or `orbus`.
3. Look up stops/routes first; use their exact GTFS IDs for departures/trips/shapes.
4. Check `meta.warnings`, `meta.latest_data`, `meta.truncated` and the service date before using
   results. Static departures are schedules, not predictions or proof of operation.

## Commands

Run `python3 skills/gtfs-nz/scripts/cli.py <command> [flags]`.
Every command supports `--json`, `--cache-dir PATH`, and `--max-age SECONDS`
(default 86400). Every command supports `--refresh`; data queries support `--limit N` (default 100,
maximum 10000). All commands reuse fresh ZIPs unless `--refresh` is given. Expired caches are refreshed; a failed refresh is an error.

How to install

The exact contents, by fingerprint

mdr add thecolab-ai/.skills/gtfs-nz@sha256:ca69f522c466dddd

The line at the top of this page pins the label git:20261008.7621d3b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
