Just today we completed work on the Saturday Morning with Kim Hill programme archive.
This opens up all the content that has been broadcast on the show since the start of the year.
All audio can be downloaded in MP3 format, and in Ogg Vorbis since August. The programme archive page lists a summary of all programmes, and you can also search audio and text.
Morning Report and Nine To Noon now have Ogg Vorbis, and I expect to be able to open up their older content in the next few weeks.
Other programmes will have Ogg Vorbis added as I have time.
I have a test RSS feed (the URL might change) with Ogg enclosures for Saturday Morning. Send any feedback to webmaster at radionz dot co dot nz.
