In reply to JCB42:
I had a quick look but also couldn't find much DMM stuff for sale in NZ. I used the old 'site:.nz' to search for DMM stuff, and found almost nothing - which fits my recollection last time I went back that it was BD and petzl that had pretty much cornered the NZ market.
Australia is probably your best bet. I had a quick look, and found one set of DMM QDs here:

There are probably a lot more shops there too.
In terms of Mammut - you're probably out of luck.
