There were two great reasons to buy the Samsung Galaxy S5 from Vodafone - they were the only retailer with the Gold edition, and their network has 4G coverage in more areas.

So we created a digital gold rush, where prizes were hidden in 4G areas all around the country, and buyers of the S5 could drop gold pins anywhere on a map of NZ. The closest guesses won the prizes. It was NZ's most successful S5 launch.
