JBHifi at Mt Gravatt (not Garden City), has the Collaborative Jurassic Park set and Back To The Future, plus several of the more recent Studio Series Deluxes. I went there for Junkheap, as the website says it was there (and their own inventory system says there were 2), but I couldn't find them, and the staff there couldn't find them.
I had it on order at the Garden City store for 3 weeks now, and it still hasn't come in yet, so I might just have to wait for the Amazon release on September 15th.
