Air New Zealand Air Points - Air NZ Snack

I was on a couple of Air NZ flight several months ago (NRT-CHC/CHC-LAX) and really enjoyed the snack we got with the initial beverage service. It was sort of a potato chip, air puffed crisp. Its hard to discribe but was really good. Anyone able to tell me what it is and is it avalible in the US?

Thanks for your help!

p.s. enjoyed the service in the new J seats and very friends FAs - didn't like the seats but that is a personal preference, missed being able to look out window easily.

Vege crisps! No idea whether or not available in US.

It's cassava/e - should be available from health stores (not that it's THAT healthy!)

Not even remotely healthy.
