If you after family notices for earlier years (back to 2006), these are available at The Treasury, Thames - copies can be requested via their research service.
Alternatively the Thames Library and Hauraki Herald Office has copies that you can go in and browse covering all years.
Another old Thames Newspaper that has come to light is THE THAMES SENTINEL AND MINERS JOURNAL, published by William Wood back in the 1890s.
