A portolan/stac catalog of every known available non-AI generated field boundary.
This dataset covers Irrigated Land. Adapted by Ministry for the Environment and Statistics New Zealand to provide for environmental reporting transparency
The spatial data covers all mainland regions of New Zealand, with the exception of Nelson, which is not believed to contain significant irrigated areas. The spatial dataset is an update of the national dataset that was first created in 2017. The current update has incorporated data from the 2019 – 2020 irrigation season.

The latest edition is also available at a stable path: nz/latest/nz.parquet. All editions together through the S3 glob s3://ftw/harmonized-field-data/nz/year=*/*.parquet (see the AGENTS.md for the DuckDB setup; plain https cannot expand *).
Properties that are the same for every field are stored once, in the GeoParquet file's collection metadata rather than as columns (latest edition shown; a client reading only the table will not see them):
admin:country_code: NZQuery the published files in place with DuckDB; nothing needs downloading first.
This catalog is a mirror: the data is produced and licensed by Aqualinc Research Limited and republished here as cloud-native GeoParquet and PMTiles by Fields of the World. Each edition was downloaded from the source and converted with fiboa-cli 0.21.0, vecorel-cli 0.2.15:
The conversion is deterministic and lives in fiboa-cli; changes to how a column is mapped are made there, not in this catalog.
