Safari can’t open the page “feed://www.listener.co.nz/sm/rss/latestissue.rss”. The error is: “The feed could not be loaded because the content is not in a known feed format.” (PubSub:2)

Fixed now. Thanks for that.

..what about an RSS feed?

..the new year

And while we work on a clean feed you will find that Fiona's daily TV and Radio updates appear dailiy in here:
Latest Issue RSS

.. along with any other featured articles we put live that day.

Note though that once each week you will see a swathe of the magazine content arrive with links to stuff you can't read.. I know.. it's daft.. we're working on it.

Hopefully they'll be able to manage it themselves

Hopefully we can indeed. Having recently taken on the job of looking after APN's magazines online presence, I feel rather like I'm nursing a neglected puppy back to health. RSS feeds of content as it becomes available online is high on my wish list for the new year, as are commenting functionality and viewing all articles by a particular columnist.

Does the Listener have a full TV/Radio anywhere on it's site? ... Seems like there is a bit of a void there

Agreed; that's something we are investigating - historically I understand that the limitation has been the price that the broadcasters charge for the rights to publish this information online.
