I found a thread about these guys from August last year and I'm really keen to see if anyone has had any recent experiences with them. http://www.geekzone.co.nz/forums.asp?forumid=141&topicid=87955
We're considering a new build (our first) and are more than a little anxious about trying to make the right choice in who to manage this process for us. Having spoken to one of their guys now I've been pretty happy with how things have progressed. We haven't commited to the purchase of a section yet so we've still got all options open to us.
I'd be interested in hearing anyone who has managed this whole process themselves, and especially anyone that has used Key2 to manage this for them.
