National Library of New Zealand
Papers Past contains more than two million pages of digitised New Zealand newspapers and periodicals. The collection covers the years 1839 to 1945and includes 70 publications from all regions of New Zealand.
Recent television and radio broadcasts are usually freely available from the broadcaster's web site, or as podcasts via iTunes.
Older broadcasts are rarely freely available. If you are looking for news from the last few months, or years, you will need to use a news and current affairs database.
