I am undertaking non-commercial historical and geospatial research on legacy telecommunications infrastructure in Auckland. Please advise whether any publicly releasable datasets, registers, reports, archived map indexes, metadata catalogues, or data dictionaries exist concerning: historic telecommunications routes, ducts, conduits, cable corridors, pits, cabinets, exchanges, and exchange-service areas; historical road-corridor works, permits, consents, notices, occupation records, engineering drawings, or as-built records identifying telecommunications construction; and metadata, data dictionaries, archive catalogues, accession lists, map indexes, or register descriptions identifying the existence, date range, geographic coverage, custodianship, format, and access conditions of these records. Geographic focus is the present Auckland Council area, including legacy Auckland City, Manukau City, North Shore City, Waitakere City, Papakura District, Franklin District, and Rodney District areas where applicable. I do not seek live operational network geometry, asset-security information, customer or address-level service data, network capacity information, access-control details, or other information unsuitable for public release. Generalised, historic, de-identified, superseded, aggregated, or index-level material would be useful. Preferred release formats are GeoPackage, GeoJSON, Shapefile, CSV, PDF map index, scanned historic plans, report PDFs, or a catalogue/archive reference with sufficient metadata to support a separate access request where appropriate.

There is currently limited public visibility of the historical development and spatial footprint of Auckland's legacy telecommunications network. Researchers, local historians, GIS practitioners, infrastructure planners, and heritage groups cannot readily determine what historical records exist, which agency holds them, their geographic and temporal coverage, or whether non-sensitive versions can be reused. This creates unnecessary duplication of research effort and makes it difficult to document the relationship between telecommunications development, street works, urban growth, exchange areas, and other public infrastructure over time.

Publishing suitable historic, generalised, or index-level material would enable transparent, non-commercial research without exposing live network operations or sensitive asset information. A dataset, archive catalogue, or map index would allow users to identify relevant records by location, period, asset type, and source agency. Where release of spatial geometry is not appropriate, metadata and catalogue-level information would still provide a practical discovery tool, supporting evidence-based heritage documentation, historical mapping, research into public-works coordination, and more efficient future requests for specific archived material.
