Each piece of Ancient Kauri follows a fully traceable journey from excavation to final registration.

This system ensures origin, handling, and identification are recorded at every stage.

When excavated, each log is formally recorded and assigned a milling statement number issued under the New Zealand Ministry for Primary Industries (MPI).

This record includes the date and location of recovery, establishing the material’s point of origin.

During milling and production, each slab is assigned a unique serial number by the manufacturer.

Where applicable, radiocarbon analysis is conducted to determine the burial age of the material within the ancient peat system.

Each serial number is then registered within the Ancient Kauri archive system, creating a dedicated reference record for the piece.

This record links origin, processing, and material identity into a single traceable profile.
