The Treasury, Thames, an archive and family history research centre for the Hauraki region, is housed in the historic Carnegie building. The Coromandel Heritage Trust administers the building and the collection it houses. One of the Trust's aims is to collect and preserve the records of the Hauraki region. This includes family records, area records, business and organisation records. The collection includes the Pioneer Family Register, school and cemetery records, books and papers about the towns and businesses/organisations of the region, family history books, papers about the families of the region, mining information, photos and maps. There is also a comprehensive collection of books. The books include a large collection of Government Gazettes, Maori (NZ-wide), towns of New Zealand, overseas countries of interest to genealogists, and Captain Cook. There are oral histories, digital stories, and various CDs and fiche of interest in particular to genealogists. A film reader and films of the early Thames newspapers are also housed here. Fiche machines and computers are available to use. An indexing group meets regularly and we hope to have the index up and running soon.
