Many of the local libraries will have microfilms of their district newsppers..worth checking library catalogues
eg Auckland and Hamilton have a lot of titles
If there is a particular paper you want..check the National library index and see if they have an interloan copy
for the charge of a normal interloan they will send you a copy of the film that you can view at your local library (if it has a microfilm machine that is!!
