under the Public Records Act 2005. Variations in collection size The table below shows the variation in the reported size of Ngā Taonga Sound & Vision's collections. The figures are drawn from official correspondence, documents and websites. Notably the reported size of the TVNZ Archive collection dropped by 212,000 items between 2013 and 2017. As custodian of the TVNZ Archive Collection since 2014, the Ministry for Culture and Heritage has never audited the size of the collection. It believes the significant drop in the reported size is because Ngā Taonga Sound & Vision is currently only estimating the size of the collection. The Ministry is waiting on the archive to complete an audit (due by August 2018). The archive will then share the methodology and total number of items with the Ministry. New Zealand Film Archive collection By 2012 the New Zealand Film Archive collection contained over 150,000 items including moving-images from 1895 to the present day. The collection includes predominantly New Zealand features and short films, newsreels, documentaries, home movies, music videos, television programmes, commercials, experimental films and video art. The collection also contains items with significant Māori content, including records of karanga, whaikorero, iwi and hapu whakapapa, powhiri, wharenui and marae, kapa haka, Waitangi Day events (from 1934), raranga, tukutuku and whakairo. There are also stills, posters, scripts, clippings, printed programmes, publicity material, production records and files, personal records, storyboards, props and costumes, animation cells, taped interviews, glass advertising slides, ephemera and equipment. Dating to before the amalgamation of the TVNZ Archive collection, the New Zealand Film Archive maintained the National Television Collection on behalf of NZ on Air. This involved constantly recording off-air broadcasts including television news, dramas, documentaries, games shows, music videos, infomercials, youth programming and sport. Māori broadcasting was archived on behalf of Te Mangai Paho, the Māori Broadcasting Funding Agency. The New Zealand Film Archive collection also holds the Chapman Collection. Deposited by Professor Robert and Noeline Chapman of the Political Studies Department at Auckland University, the collection begins with audio recordings of television news from the 1960s. From 1984 the collection contains VHS recordings of nightly news bulletins. The Chapman collection precedes TVNZ's own archival collection of television news.
