Hi, cool product. I will be working on a design and hopefully I will see it rolling out as I am based in NZ too.
There are a few retailers I can think of that this product would do well in too.

A couple of questions; do you prefer a cardboard box or clear plastic type?
Are you firm on the 4 pack or is a 2 pack an option?

Hey just an update on where our head is...
We have 2000 packs currently ready to be made up but are undecided on our packaging, we are thinking a small circular clear tube with a recycled paper insert, we want the product clearly displayed for the consumer hence this idea, and it will house 2 of our cups. With the name we are open to ideas we have a couple we have thought of but as of yet nothing is set in stone.

Cheers

Nick
