From a NLNZ Blog Post:
Through a combination of Legal Deposit and actively seeking out New Zealand music across the internet, we are rapidly accumulating a huge collection of great tunes, which we are preserving for posterity in our National Digital Heritage Archive.
Even better, an increasing number of artists are giving us permission to offer access to their music in our collection beyond the confines of the National Library building.
Unfortunately there is not currently a way of identifying the music that is available off-site, however I will be posting regular blogs here highlighting some my favourite open access music that has come into our collection.
If you happen to be on-site at our building in Wellington, there is a wealth of digital music available to stream through this site.
Access to the streaming music collection is available globally.
