New Zealand Post have continued to adopt an innovative stance with their new stamp issues by releasing a set of twenty stamps which employ 'Rub and Reveal' technology.
Each stamp features an example of Kiwi slang which has made it in to everyday New Zealand life along with an image alluding to what this slang might mean. When the black area of each stamp is rubbed it reveals the actual translation as the heat-sensitive ink reacts to touch.
