Just the man I was hoping would reply! Howdy Phil 
I was thinking that I'd leave it pretty general and guage interest in any of the centers. My hope is that someone with skills like yourself could lead the contingent down there and if there was enough interest we could do one in Wellington and up here in Auckland too.
So, if anyone's pondering the idea then please let either Phil or myself know and if it comes together we can start to get firmer numbers and locations together.
So far I'm looking at:
Auckland: 2
