I was emailed this. It apparently was made in New Zealand but I do not have any other information. It uses a conventional zip gun design: a bolt in a tube with a threaded barrel.
What makes it interesting is that it looks like both barrels can be fired at once by pressing on or pulling down the rod (on the left side of the photo).

Yes, its housed in a cell phone.
I don’t know of any New Zealand laws restricting ammo.
Zip guns often use .22 because it is more readily available, cheaper and small but mainly because it operates at a very low pressure. There is much less chance of losing your hand 
Saying that .. I would never risk my trigger finger on something like that!

Interesting that whomever built it used .22lr . Is that round more available under NZ firearm laws?
Seem to recall that’s why the Chechen rebels used .22lr so extensively.
