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

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