New Zealand Law MCP

New Zealand law database for the Model Context Protocol, covering privacy, harmful digital communications, electronic transactions, companies, commerce, and publications classification legislation with full-text search.

MCP Registry: eu.ansvar/newzealand-law-mcp npm: @ansvar/newzealand-law-mcp License: Apache-2.0

Deployment Tier

SMALL -- single tier, bundled. New Zealand has a smaller legislative corpus that fits comfortably within Vercel and npm size limits.

| Tier | Platform | Database | Content | |------|----------|----------|---------| | Bundled | Vercel (Hobby) / npm (stdio) / Docker | Full database (~100-200 MB) | All NZ Acts, regulations, FTS search, international cross-references |

No tiering is required. The full New Zealand legislative database fits within the Vercel 250 MB function bundle limit, similar to the Swedish and Slovenian Law MCPs.

Data Sources

| Source | Authority | Method | Update Frequency | License | Coverage | |--------|-----------|--------|-----------------|---------|----------| | New Zealand Legislation | NZ Government, Parliamentary Counsel Office | XML Download | Weekly | CC BY 4.0 | All NZ Acts, legislative instruments, regulations | | NZLII | AustLII / University of Canterbury | HTML Scrape | Weekly | NZLII Terms of Use | Case law, tribunal decisions, law reform reports |

Languages

New Zealand legislation is primarily in English. Some legislation includes provisions in te reo Maori (the Maori language), particularly:

• Te Ture Whenua Maori Act 1993 (Maori Land Act)
• Treaty of Waitangi related legislation
• Maori Language Act 2016

The MCP indexes both English (en) and Maori (mi) text where available.

Database Estimates

| Component | Size Estimate | |-----------|---------------| | NZ Acts and regulations | ~80-120 MB | | Case law (via NZLII) | ~30-60 MB | | Cross-references and metadata | ~5 MB | | Total | ~100-200 MB |

Delivery strategy: Full database bundled in npm package (same approach as Swedish and Slovenian Law MCPs). No tiering or runtime download needed.
