Along with Joan I attended NDF 2014 a couple of weeks back.
They appear to have loaded most of the recorded sessions now and these can be viewed here.
The sessions that I attended and would also recommend are as follows (sometimes the Q&A at the end of the presentations can be as useful as the main event itself):
Brewster Kahle – Universal Access to All Knowledge
Mia Ridge – Collaborative collections through a participatory commons
Claire Murdoch – Digital Publishing and Museums
Panel Discussion – Open progress in NZ – NDF 2014
Vanessa Gibbs – mining Marsden: the four pieces of the puzzle
Frank Stark – Ngā Taonga: Tuple or nothing
Karl Kane & Tim Parkin – Designing the Library of the Future
Rick Shera – It’ll be the death of us (copyright and Facebook etc).
