Clever Kash is a digital moneybox designed to teach kids about money. It connects with the bank's mobile banking app seamlessly, allowing kids to "swipe" coins into the little yellow elephant. In two years it went from interesting concept to central brand piece from one of the country's biggest banks - and is in the homes of more than 200,000 New Zealanders.

It won Gold at Cannes, a D&AD Yellow Pencil and Wood Pencil, a Webby Award and a truck load of others. One Show only gave it a couple of bronzes but we'll let that slide.

UPDATE: Clever Kash has now been licensed to Bank of Changsha, China, a bank with 11 million customers. I believe they call it “Happy Elephant”.
